Weathering the Storm: Climate Resilience in Supply Chains

Thu, 10 Oct 2024 12:57:11 GMT

Supply chains, the intricate networks that connect businesses and consumers worldwide, have become increasingly vital to modern economies. They ensure the smooth flow of goods and services, underpinning our daily lives. In recent decades, supply chains have evolved into sophisticated systems, a marvel of human ingenuity and cooperation. However, this complex interconnectedness also makes them vulnerable to a growing threat: climate change.

Supply Chains and Climate Change

Supply chains are a major contributor to climate change due to their reliance on fossil fuels for transportation, energy consumption, and manufacturing processes. According to the Carbon Disclosure Project (CDP), of the 18,600 companies that disclosed their carbon emission data through the CDP in 2022, scope 3 emissions (often referred to as supply chain emissions) are, on average, 11.4 times greater than scope 1 and 2 emissions (often referred to as operational emissions) [1]. Additionally, the production and consumption of goods and services within supply chains contribute to emissions through energy use, deforestation, and waste generation.

Not only are supply chains significant contributors to climate change through greenhouse gas emissions, but they are also increasingly impacted by its adverse effects. A study from the University of Oxford estimates that climate change is already jeopardizing global trade and economic activity, putting a staggering US$81 billion of trade and US$122 billion of economic activity at risk annually. Climate-related events such as extreme weather, rising sea levels, and natural disasters pose significant risks to supply chain operations. For example, the summer of 2022 brought low water levels to the Rhine River, causing severe delays to shipping arrivals and departures. Some vessels were forced to sail with cargoes at just 25% of capacity as Europe endured its worst drought in 500 years [3].

Mitigation and building resilience

To mitigate climate change and enhance supply chain resilience, organizations must take proactive steps. One crucial strategy is to reduce greenhouse gas emissions throughout the supply chain. This can be achieved by transitioning to renewable energy sources, improving energy efficiency, and adopting sustainable practices. Additionally, organizations can support suppliers who are also committed to reducing their environmental impact.

Building resilience against climate-related supply chain risks is equally important. Supply chains must become more diversified, collaborative, and adaptable. Long-term planning and risk-based management are essential to proactively address climate-related challenges. This can be achieved using the following strategies:

Avoiding over-reliance on single regions or suppliers.
Sharing data across the supply chain to enable better monitoring, prediction, and collective action in response to extreme weather patterns.
Investing in early warning systems to allow for timely responses and mitigation efforts.
Identefying vulnerable points in supply chains and specific risks posed by climate change such as vulnerable waterways and ports, endangered transportation infrastructure, unprotected manufacturing and production facilities, and agricultural production threatened by droughts and extreme weather.

In conclusion, climate change poses a significant threat to global supply chains. By understanding the risks and taking proactive measures, organizations can mitigate their own environmental impact and build resilience to climate-related disruptions. Supply chain companies and industries heavily reliant on supply chains should be at the forefront of efforts to reduce their carbon footprint. Like a smoker who realizes the negative impact of their habit on themselves and others, supply chain organizations should prioritize carbon reduction. This not only safeguards their own operations but also helps create a more sustainable and resilient global economy.

Climate Change and War: A Complex Interplay

Thu, 05 Sep 2024 17:31:29 GMT

How Conflicts in Ukraine, Palestine, and Sudan in 2024 are Shaped by and Impact the Global Climate Crisis

In 2024, the world faces ongoing conflicts in Ukraine, Palestine, and Sudan, which are not only tragic in human terms but also profoundly interconnected with the global climate crisis. As global temperatures rise and environmental degradation worsens, climate change acts as both a trigger and amplifier of conflict. At the same time, wars damage ecosystems, disrupt environmental governance, and increase greenhouse gas (GHG) emissions, intensifying the environmental toll.

Climate Change as a Conflict Trigger

Climate change has long been recognized as a "threat multiplier," intensifying underlying tensions, particularly in regions already facing political instability and resource scarcity. For example, Sudan has experienced prolonged droughts that severely impact agriculture, increasing competition over resources like water and fertile land. These conditions can foster disputes between communities, particularly in rural areas, fuelling the ongoing conflict (World Resources Institute, 2021) .

Similarly, in Ukraine, the war is disrupting access to critical energy sources, including clean energy infrastructure. Ukraine has been on a path toward expanding renewable energy; however, the war has halted many projects, making the energy transition harder and deepening reliance on fossil fuels (IEA, 2022).

News Spotlight: War’s Devastating Environmental Impact

Recent news reports show how wars in 2024 are exacerbating environmental degradation. For instance, the war in Ukraine has led to the destruction of key energy infrastructure, including the Zaporizhzhia Nuclear Power Plant, raising concerns of catastrophic contamination (BBC News, 2024). In Palestine, the bombardment of cities has destroyed natural habitats and damaged water supplies, while in Sudan, deforestation and desertification are rapidly increasing due to uncontrolled migration and urban sprawl as millions flee the violence (Al Jazeera, 2024).

These crises illustrate that while war is an immediate human disaster, the long-term environmental consequences can linger for decades, adding stress to already fragile ecosystems.

Wars Escalate Greenhouse Gas Emissions

One often overlooked consequence of war is its impact on GHG emissions. A recent study published by the Journal of Environmental Science and Policy revealed that military operations, including the movement of troops and equipment, fuel massive carbon emissions. In Ukraine, the burning of fossil fuels to power military operations and replace damaged infrastructure has pushed carbon emissions back up, negating progress made in recent years (Environmental Science and Policy, 2023).

Additionally, damage to Ukraine’s forests and agricultural land has reduced carbon sinks, while the destruction of renewable energy plants has forced a temporary shift to more carbon-intensive energy sources, further compounding the issue (UNEP, 2023).

Climate Refugees: The Intersection of Conflict and Migration

Wars create large-scale displacement, and when combined with climate impacts, the situation worsens. In Sudan, nearly 4 million people have been displaced by the ongoing conflict, exacerbating environmental stress in neighboring countries where refugee camps are located. The lack of sustainable infrastructure in these camps leads to deforestation and water pollution, which not only damages the environment but also undermines the quality of life for displaced people (UNHCR, 2024). According to the World Bank, climate-induced migration is expected to increase dramatically if climate action and conflict resolution are not prioritized in global policy discussions.

Sudan’s Extreme Weather in 2024: A Double Blow of Floods and Droughts

In 2024, Sudan faced a devastating combination of floods and droughts, further exacerbating the ongoing humanitarian crisis caused by conflict. Climate change has intensified the severity and frequency of extreme weather in the region. According to recent reports, Sudan experienced one of the worst floods in decades, displacing thousands of people, destroying infrastructure, and contributing to the spread of waterborne diseases (UN, 2024). At the same time, large parts of the country suffered from prolonged droughts, crippling agricultural production and deepening food insecurity.

The interaction between extreme weather events and ongoing conflict has created a "climate-conflict nexus." With resources already scarce due to war, floods and droughts have amplified tensions among communities, particularly in rural areas. Water sources have become unreliable, and competition over fertile land has increased, leading to further displacement and violence (World Resources Institute, 2024).

Additionally, the environmental damage caused by these extreme weather events is immense. Floodwaters have destroyed homes, crops, and infrastructure, while the drought has led to land degradation, making recovery even more difficult. This situation has placed further strain on refugee camps and humanitarian efforts already struggling to cope with the impacts of conflict (UNHCR, 2024).

Linking Science to Solutions: Building Climate Resilience in Post-Conflict Recovery

Scientific research emphasizes the need for integrating climate resilience into peace-building and recovery efforts in conflict zones. Rebuilding efforts should prioritize sustainable energy solutions such as solar and wind, as well as water conservation and reforestation projects. For example, Ukraine’s post-war recovery could serve as a model for green reconstruction by focusing on renewable energy and infrastructure (World Bank, 2023).

In Palestine, efforts to manage water sustainably through modern technologies like desalination could help prevent future conflicts, while reforesting degraded land in Sudan could create jobs, reduce emissions, and restore ecosystems (FAO, 2023).

The conflicts in Ukraine, Palestine, and Sudan demonstrate that climate change is not just an environmental issue but a security challenge. As wars exacerbate environmental degradation and climate change triggers resource conflicts, we must address both together. Integrating climate resilience into post-conflict recovery will not only prevent future wars but also contribute to the global fight against climate change.

Climate Forcers: The Hidden Drivers of Global Warming

Thu, 05 Sep 2024 16:17:33 GMT

We often hear about carbon dioxide as the primary reason behind global warming, but there's more to the story. A variety of substances, known as climate forcers, are playing a significant role in heating or cooling our planet. Let's delve into the world of climate forcers and understand how they're contributing to the climate crisis.

Climate forcers come in two main types: Short-Lived and Long-Lived .

Long-Lived Climate Forcers (LLCFs):

Long-lived climate forcers are greenhouse gases that remain in the atmosphere for an extended period, ranging from several decades to centuries. The most well-known LLCFs include:

Carbon Dioxide (CO2): The primary greenhouse gas emitted through human activities, particularly the burning of fossil fuels and deforestation. CO2 can remain in the atmosphere for hundreds to thousands of years.
Methane (CH4): Although methane is also considered a short-lived climate forcer due to its shorter atmospheric lifetime (about 12 years), its long-term impact on climate is significant because it is much more effective at trapping heat compared to CO2.
Nitrous Oxide (N2O): Emitted from agricultural activities and industrial processes, nitrous oxide has a lifetime of about 114 years.
Fluorinated Gases: These include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), which are synthetic gases used in various industrial applications. They can remain in the atmosphere for thousands of years.

LLCFs contribute to long-term climate change by trapping heat in the atmosphere, leading to a gradual increase in global temperatures. Their persistent nature means that even if emissions were to stop today, their effects would continue to influence the climate for many years to come .

Short-Lived Climate Forcers (SLCFs):

Short-lived climate forcers are substances that have a much shorter atmospheric lifetime, typically ranging from a few days to a few decades. Despite their short lifespan, SLCFs can have a significant impact on the climate and air quality. Key SLCFs include:

Black Carbon: A component of particulate matter (PM) produced from incomplete combustion of fossil fuels, biofuel, and biomass. Black carbon absorbs sunlight and warms the atmosphere but only remains in the atmosphere for days to weeks.
Tropospheric Ozone (O3): Unlike stratospheric ozone, which protects us from harmful UV radiation, tropospheric ozone is a pollutant formed by the reaction of sunlight with pollutants like nitrogen oxides (NOx) and volatile organic compounds (VOCs). It has a lifetime of a few weeks.
Hydrofluorocarbons (HFCs): While some HFCs are long-lived, others have shorter lifetimes and are used as refrigerants and in other industrial applications.

SLCFs can have both warming and cooling effects on the climate. For example, black carbon has a warming effect, while some aerosols can reflect sunlight and cool the atmosphere. The impact of SLCFs is more immediate compared to LLCFs, making them a critical target for short-term climate mitigation efforts.

In addition to the main short- and long-lived forcers we discussed earlier, here are some others:

Water Vapor (H₂O)

Impact: Water vapor is the most abundant greenhouse gas, but it behaves differently than CO₂ or methane. It amplifies the effects of other greenhouse gases because, as the atmosphere warms due to CO₂ or methane, more water evaporates into the air. This extra water vapor traps more heat, creating a feedback loop that increases global warming.
Duration: It has a short life cycle, cycling out of the atmosphere through precipitation within days, but it plays a critical role in the overall climate system.

Aerosols (Reflective Particles)

Impact: Aerosols, like sulfate particles, reflect sunlight back into space, which cools the Earth. They are often produced by industrial pollution, burning of fossil fuels, and volcanic eruptions. While they have a cooling effect, this does not counterbalance the warming from greenhouse gases.
Duration: Aerosols have a short lifespan in the atmosphere (days to weeks), but their cooling effects can mask some of the warming caused by greenhouse gases.

Clouds

Impact: Clouds can act as both climate forcers and climate dampeners. Low clouds tend to reflect sunlight, having a cooling effect, while high clouds trap heat, contributing to warming. Their overall effect on climate is complex and depends on various factors such as altitude and type.

Smoking and Climate Change

Thu, 29 Aug 2024 15:29:44 GMT

The Hidden Link Between Cigarette Smoking and Climate Change

When we think about climate change, the usual suspects that come to mind are industries, automobiles, and deforestation. However, there is an often-overlooked contributor to environmental degradation and climate change: cigarette smoking. While smoking is primarily recognized for its health impacts, its environmental footprint is significant and alarming.

Cigarette Production and Deforestation

The journey of a cigarette begins with tobacco farming, a process that heavily relies on deforestation. Vast areas of forests are cleared to make way for tobacco plantations. According to the World Health Organization (WHO), tobacco farming is responsible for the loss of 200,000 hectares of forests each year. These forests, which act as carbon sinks, are vital in absorbing CO2 from the atmosphere. When they are destroyed, the carbon stored in trees is released back into the atmosphere, contributing to global warming.

Carbon Emissions from Tobacco Manufacturing

The manufacturing process of cigarettes is another significant source of carbon emissions. It’s estimated that the production of just 300 cigarettes (around 15 packs) results in the emission of about 1 kilogram of CO2. With nearly 6 trillion cigarettes produced annually worldwide, the carbon footprint is staggering.

Moreover, the energy consumption involved in curing tobacco, manufacturing cigarettes, and packaging is considerable. Factories rely on fossil fuels for energy, further increasing the carbon emissions associated with cigarette production.

Environmental Impact of Cigarette Waste

Cigarette butts are the most discarded waste item worldwide, with about 4.5 trillion butts littered each year. These butts are not just unsightly; they are also toxic. They leach harmful chemicals, such as nicotine, heavy metals, and carcinogens, into the soil and waterways, harming wildlife and ecosystems.

But beyond the direct pollution, the decomposition of cigarette butt’s releases greenhouse gases. Though each individual butt contributes a small amount, the cumulative impact of trillions of discarded butts is significant.

Fires Caused by Smoking

Another link between smoking and climate change is the role of cigarettes in starting wildfires. Carelessly discarded cigarette butts are a common cause of forest fires, which can result in the loss of vast areas of forest and significant carbon emissions. Wildfires not only release carbon stored in trees but also reduce the planet’s capacity to absorb CO2, creating a vicious cycle.

The Bigger Picture

While smoking is often framed as a personal choice with personal health consequences, it is also an environmental issue with global implications. The entire lifecycle of a cigarette — from production to disposal — contributes to climate change. Reducing smoking rates worldwide could have a meaningful impact not only on public health but also on the health of our planet.

This intersection between personal behavior and global climate change highlights the importance of addressing all contributors to environmental degradation, no matter how seemingly small. By raising awareness of the environmental impacts of smoking, we can encourage more people to quit, benefiting both their health and the planet.

I-RECs: A Catalyst for Renewable Energy Investment in Qatar

Sat, 24 Aug 2024 15:15:18 GMT

As a signatory to the Paris Agreement, the State of Qatar has reaffirmed its commitment to combating climate change by setting ambitious targets. The State aims to reduce greenhouse gas (GHG) emissions by 25% from 2010 levels and achieve an 18% share of renewable energy, primarily solar photovoltaics (PV), in its electricity generation mix by 2030. This is a significant challenge, especially given Qatar’s status as having the highest GHG emissions per capita globally.

Qatar’s economy, heavily reliant on its abundant natural gas reserves, reached a record Gross Domestic Product (GDP) of $236 billion USD in 2022, with projections suggesting growth to $320 billion USD by 2030. To accommodate this economic expansion, the Qatar National Renewable Energy Strategy (QNRES) anticipates energy demand to rise to 11,500 Megawatts (MW) by 2030, up from 9,600 MW in 2021. Consequently, the supply capacity from conventional sources is planned at 13,200 MW, necessitating approximately 2,900 MW of solar PV capacity to meet the 18% renewable energy target.

Based on IRENA’s Energy Profile for Qatar, the average solar PV potential is 1.7975 MWh/KWp annually. This means that the 2,900 MW of solar PV capacity could generate around 5.2 TWh of electricity each year from 2030 onwards, equivalent to 5.2 million International Renewable Energy Certificates (I-RECs) .

I-RECs are Environmental Attribute Certificates (EACs) that represent the environmental attributes of electricity generated from renewable resources. They are issued by certified issuers accredited by the International Tracking Standard Foundation (ITS), ensuring transparency and credibility. Each I-REC represents 1 megawatt-hour (MWh) of renewable electricity, providing detailed information about its origin, technology, region, and vintage.

Qatar’s anticipated economic growth over the next five years is expected to attract significant investments, with many international companies eager to contribute to and benefit from this growth. Aligning this economic expansion with global corporate initiatives like RE100, which aims for 100% renewable electricity procurement by 2050, could further boost investments in solar PV in Qatar. RE100 has attracted a significant number of leading businesses, including industry giants like Apple, Google, Intel, 3M, and many others. As the global push for net-zero emissions and renewable energy adoption intensifies, the demand for I-RECs has surged. Since 2020, the annual growth rate of I-REC issuance has been an impressive 100%, underscoring the increasing importance of this tool in the transition to a sustainable energy future.

REC Market Development in Qatar

To fully leverage the benefits of Renewable Energy Certificates (RECs), Qatar can implement several strategic steps to develop a robust REC market:

Establish a Clear Regulatory Framework: A transparent and well-defined regulatory framework is crucial for the successful development of a REC market. This framework should outline the rules and guidelines for REC issuance, trading, and compliance.
Promote REC Trading: The government can foster REC trading by setting up a REC registry and facilitating transactions. This can be achieved through various initiatives, such as creating an online platform for REC trading and providing incentives for market participants.
Incentivize REC Purchases: Government agencies and businesses can be encouraged to purchase RECs through financial incentives, tax benefits, or recognition programs. These incentives can drive demand for RECs and support the growth of renewable energy projects.
Educate the Public: Raising awareness about the benefits of RECs and how they contribute to renewable energy development is essential. Public education campaigns can help increase participation in the REC market and promote a culture of sustainability.

RECs present a valuable tool for Qatar to accelerate its progress towards its renewable energy targets and ambitious climate goals. By developing a robust REC market, Qatar can stimulate investment in renewable energy, encourage consumer adoption, and effectively track progress towards its sustainability objectives. This strategic approach will not only help Qatar meet its environmental commitments but also position the country as a leader in the global transition to a sustainable energy future.

Driving Climate Action Through Renewable Energy Finance

Thu, 01 Aug 2024 15:15:10 GMT

The urgency of addressing climate change has never been more apparent. As global temperatures continue to rise and the impacts of extreme weather events become more severe, the need for sustainable solutions is critical. Renewable energy finance is at the heart of these solutions, providing the necessary capital to transition from fossil fuels to clean energy sources. I’m here to walk you through the pivotal role of finance in advancing climate action and to share insights from my experience in the field.

The Role of Finance in Climate Action

Overview

Finance is the lifeblood of climate action. It enables the development and deployment of technologies and infrastructures necessary for a sustainable future. From solar farms to wind turbines, the capital required to bring these projects to fruition is substantial. However, with the right financial mechanisms and investments, we can accelerate the transition to a low-carbon economy.

Challenges and Barriers

In renewable energy projects, several challenges and barriers arise. Key factors include access to financing, often hindered by perceived risks and high initial costs. Expected returns are crucial for investors who require confidence in long-term profitability. Additionally, the costs associated with renewable energy technologies and projects can be significant, requiring substantial upfront capital. Addressing these challenges involves innovative financial mechanisms, effective risk assessments, and supportive policies. Overcoming these obstacles is essential for making renewable energy projects more appealing and feasible, and ultimately, promoting a transition to a sustainable and low-carbon economy.

There are three main sources of finance for renewable energy (RE) projects: banking systems, private investors, and public finance instruments. Each source faces obstacles, such as a challenged commercial lending sector, high capital requirements, and macroeconomic barriers. These limitations result in fewer RE plants being constructed, impacting the transition to renewable energy.

The lack of support instruments leads to higher project risks, deterring investors seeking stable returns. Developers must compensate for these risks by demanding higher expected returns, making projects less attractive to capital providers. This hurdle further limits the pool of potential investors and increases the difficulty of securing financing. Furthermore, the absence of financial instruments like guarantees could significantly reduce the perceived risk of renewable energy projects. Without these risk mitigation mechanisms, investors face higher uncertainty, which leads to higher required returns. This increased cost of risk further limits the pool of potential investors and reduces the number of plants that can be constructed.

The third barrier refers to the substantial upfront capital investment required for renewable energy projects, particularly pronounced in developing countries. Coupled with often limited access to affordable financing, developing countries face significant challenges in bridging the financial gap for renewable energy projects. Additionally, the complexities of project development, including securing land rights, permits, and grid connections – can further escalate costs.

Renewable Energy Finance: Key Considerations

Investments Trends

In recent years, there has been a notable shift in investment trends towards renewable energy. Solar and wind projects have seen substantial growth, driven by technological advancements and favourable policies. Energy storage is another area gaining traction, as it addresses the intermittency issues associated with renewables. These trends indicate a broader movement towards sustainable investments, which reflects the increasing importance of Environmental, Social, and Governance (ESG) criteria in decision-making.

Risk Assessment

While the renewable energy sector offers promising returns, it is not without risks. Investors must carefully assess factors such as regulatory changes, technological risks, and market dynamics. Due diligence is crucial, as it helps identify potential pitfalls and mitigate risks. Structured finance solutions, such as green bonds and public-private partnerships, can also play a significant role in de-risking projects and attracting capital.

Future Outlook

Looking ahead, we expect continued growth in the renewable energy sector. Technological innovations, such as advanced energy storage and smart grid technologies, will further enhance the viability of renewables. Additionally, increasing pressure from regulators and consumers for sustainable practices will drive more businesses to adopt green energy solutions.

For investors, the key to success in this sector lies in understanding the unique dynamics of renewable energy finance. It is essential to stay informed about policy developments, technological advancements, and market trends. Collaboration between public and private sectors is also critical, as it can unlock new financing mechanisms and expand access to capital. Finally, transparency and accountability are vital in building trust with stakeholders and ensuring the long-term success of renewable energy projects.

As we move towards a sustainable future, the role of finance in supporting renewable energy cannot be overstated. By investing in clean energy projects, we are not only addressing climate change but also fostering economic growth and social well-being. I invite you to join me and enerQA in exploring the vast opportunities in this field. Together, we can drive meaningful change and create a more sustainable world.

GHG Emissions: The Burden on our Planet

Tue, 30 Jul 2024 15:18:23 GMT

Greenhouse gases (GHG) emissions are a serious issue for our world. It has been demonstrated that in recent decades, the rise has accelerated. It is evident that, overall, the trend has been upward over the past 170 years, from 4.2 to approximately 54 billion tons of CO 2 equivalent (CO 2 eq) (an increase of 1183%), between 1850 and 2022. However, the last 40 years of the same period have accounted for more than 50% of all emissions. Put otherwise, a little 23% of that timeframe accounted for over half of the emissions during the same timeframe.

In the meantime, there has been an average annual change of +2% across those years. Additionally, positive shifts have greatly exceeded the negative ones; with the maximum Year-On-Year (YoY) percentage being just below 10% from 1949 to 1950; 4 years following the end of the second world war.

On the contrary, the greatest decrease in YoY% was observed between 1944 and 1945, towards the end of World War II, and it was by 5.87%. This was followed by the 4.99% in 1919, one year after the end of World War I, whilst the third largest decline happened more recently in 2020 during the Covid-19 outbreak.

To sum up, the overall trend reflects the large impact of human activities on the amounts of GHG emissions, as it is directly affected by the major events associated with biggest switches in YoY% change during the period.

Breathing vs. Burning: The Carbon Footprint Contrast

Thu, 25 Jul 2024 12:57:27 GMT

The human body, a marvel of biological engineering, produces carbon dioxide (CO 2 ) as a natural byproduct of respiration. While essential for life, this CO 2 emission often gets overshadowed by the staggering amounts of CO 2 released through human activities, particularly the burning of fossil fuels. This article delves into the shades of these two sources of CO 2 , comparing their magnitudes and implications for our planet.

Factors influencing CO 2 exhaled:

Age: Children generally have lower CO 2 emissions due to smaller lung capacity and lower metabolic rates compared to adults.

Exercise: Physical activity significantly increases CO 2 production and exhalation due to higher energy demands and faster breathing rates.

Weather/Seasons: Hot weather can increase respiration rate, while cold weather might decrease it slightly.

Altitude: Higher altitudes have lower air pressure, leading to increased respiration rates to compensate for less oxygen per breath.

Individual Variations: Metabolism, body size, and overall health can influence CO 2 production and exhalation rates.

CO 2 from Breathing: A Drop in the Bucket

The average person exhales roughly 336 kilograms of CO 2 annually (note that the average annual CO 2 exhaled per person can range from approximately 190 kg to 450 kg, with a wider range due to various influencing factors), a considerable amount when viewed in isolation. However, this CO 2 is part of the natural carbon cycle. The carbon we breathe out originates from the plants we consume, which, in turn, absorb CO 2 from the atmosphere during photosynthesis. Thus, our respiratory CO 2 is considered "carbon neutral" and doesn't contribute to the net increase of CO 2 in the atmosphere.

CO 2 from Human Activities: The Elephant in the Room

In contrast, the CO 2 emitted through human activities, primarily the burning of fossil fuels for energy, transportation, and industrial processes, is the main driver of climate change. These activities release CO 2 that was previously locked away for millions of years, disrupting the natural carbon cycle and leading to a rapid increase in atmospheric CO 2 concentrations.

The disparity between CO 2 emissions from breathing and human activities is evident when examining per capita emissions across different regions are shown in the above figure, which highlights that CO 2 emissions from human activities overshadow those from breathing, especially in developed regions like North America and Europe.

In conclusion, while individual actions like reducing our carbon footprint through lifestyle changes are important, addressing the climate crisis necessitates systemic shifts away from fossil fuels towards renewable energy sources and sustainable practices. The comparison between CO 2 from breathing and human activities underscores the urgent need for global cooperation in mitigating anthropogenic emissions to safeguard our planet's future.

Global CO 2 Emissions: A Disparity in Responsibility

Sudan's Energy Balance 2020

Sun, 09 Oct 2022 23:39:17 GMT

Energy supply, transformation and consumption

All units are in kilotons of oil equivalent (kTOE)

Sudan’s energy balance for the year 2020 had shown lower figures from previous years trends, while maintaining largely the same proportions of energy supply resources, transformation processes and demand sector consumptions. These lower figures are most likely attributed to the COVID-19 pandemic that caused the authorities to pose restrictions on general movement, in-country travel, gatherings and others. As shown in the Sankey diagram above, Total Final Energy Consumption (TFEC) was 9,761.1 kTOE. When compared, TFEC for 2020 is 23% less than the figure for 2017 (12,739 kTOE).

The general trends indicate that petroleum products imports have been increasing over the period (2012 – 2020), from 8.5% in 2014, to 12.5% in 2017 and 28% in 2020. This can be attributed to the noticeable declines in Sudan’s production of crude oil from 5,170 kTOE in 2014 to 4,582 kTOE in 2017 and reaching 3,524 kTOE in 2020.

The main transformation processes in Sudan’s energy balance are power generation and crude oil refining, with energy inputs of 23.4% and 29.6%, respectively, of Total Primary Energy Supply (TPES) in 2020. With an input energy of 3,912.4 kTOE, the power generation output electricity was only 52%, and hence, the significant losses seen in the power generation flow in the diagram. The oil refining processes input energy was 3,753.8 kTOE and produced a 91% output of the input energy (3,420.3 kTOE), with almost 76% of the refineries products were consumed in the transport sector, which is the highest demanding sector for petroleum products, followed by the residential sector that consumed almost 13.4%.

By energy product, petroleum products such as gasoline and diesel are generally the highest consumed, with almost 41% of the TFEC in 2020, followed by biomass, with almost 39% and lastly, electricity, with almost 21%. The residential sector is the highest demanding sector; and had a share of TFEC of around 47%, followed by transport, with 27%. Agriculture sector is the least energy consuming sector, by 6% in 2020, and yet, is the highest contributing sector to the economy, with almost 30% contribution to Gross Domestic product (GDP), according to Central Bank of Sudan (CBOS) annual reports.

Artisanal Gold Mining: Environmental Impacts of Mercury Use

Thu, 15 Aug 2019 15:15:13 GMT

Artisanal and small-scale gold mining (ASGM) is a critical economic activity in Sudan, providing livelihoods for many people across various regions. However, the widespread use of mercury in this sector poses severe environmental and health risks. Recently, these risks have been further exacerbated by the heavy rains and floods that have swept across mining areas, particularly in markets where both the milling and burning of mercury amalgamated gold occur. Figure 1 shows the Geographical distribution of artisanal mining activities (Ibrahim, 2015).

In this article, I explore the environmental impacts of mercury use in ASGM in Sudan, with a focus on soil, water, air, vegetation, wildlife, and human health. I also examine how torrential rains and floods have intensified these impacts, creating new challenges for communities and ecosystems alike.

Soil Contamination

Mercury, a well-known environmental contaminant, is frequently employed in the gold extraction process. This practice can lead to soil pollution through direct spillage during the milling operation or indirect atmospheric deposition from the combustion of amalgam. In certain mining regions where I have worked, the mercury-to-gold ratio utilized in the milling phase has been observed to range from 1.48 to 3.48 grams, with a substantial quantity of mercury being released into the environment.

The recent heavy rains and subsequent floods are expected to exacerbate soil contamination by dispersing mercury-laden soil across broader areas, including agricultural lands and residential zones. These torrents and floods will likely spread the contamination beyond the immediate vicinity of the mining activities, rendering the land unsuitable for agriculture or other productive uses over a much larger area. The dispersion of mercury through floodwaters significantly increases the risk of widespread soil infertility and disruption of microbial communities, further threatening food security and the sustainability of local ecosystems.

Air Quality Degradation

The burning of concentrated amalgam is a widespread practice within Sudan's artisanal mining sector. In specific mining regions where I have worked, the mercury-to-gold ratio used during the burning phase varied from 1.32 to 3.23 grams of mercury per gram of gold, with an average of approximately 2.14 grams of mercury per gram of gold. This process releases hazardous mercury vapor into the atmosphere, which can be transported over long distances before deposition. Inhalation of these vapors poses significant health risks, including respiratory and neurological impairments, to both miners and surrounding communities. Additionally, atmospheric mercury deposition contributes to soil and water contamination.

The heavy rains and floods are expected to compound the impact of air pollution by dispersing mercury vapor over a wider area. The turbulent weather conditions associated with the floods will carry mercury vapor and droplets far from the mining markets, where burning occurs, causing mercury to settle in areas previously unaffected. This will lead to new zones of contamination, further degrading air quality and increasing the risk of mercury exposure to a larger population.

Water Pollution

Water bodies near mining areas are particularly vulnerable to mercury contamination. During the gold extraction process, mercury spills into streams and rivers, leading to the contamination of surface and groundwater. The mercury in water can transform into methylmercury, a highly toxic compound that accumulates in aquatic organisms. This bioaccumulation in fish and other wildlife poses risks to ecosystems and the humans who rely on these water sources for drinking, cooking, and fishing.

The torrential rains and resulting floods are expected to dramatically worsen this situation. Floodwaters will wash mercury from mining sites, where both milling and burning are conducted, directly into rivers, streams, and groundwater systems. This will lead to a sharp increase in the levels of mercury pollution in water bodies, expanding the contamination zone and intensifying the risk of methylmercury formation. The floods will thus not only increase the concentration of mercury in aquatic ecosystems but also elevate the danger to communities that depend on these water sources for their daily needs.

Impact on Vegetation

Mercury contamination of soil and water adversely affects plant life. Vegetation absorbs mercury through the roots, leading to stunted growth, reduced agricultural yields, and the death of plants. Contaminated plants can also enter the food chain, posing risks to herbivores and, subsequently, to predators, including humans who consume them.

Floodwaters, driven by torrential rains, will spread mercury-contaminated soil and water over vast tracts of land, severely impacting vegetation. In areas where crops have survived the floods, they are now at risk of absorbing higher levels of mercury, making them unsafe for consumption. This situation threatens not only local agriculture but also the broader ecosystem, as contaminated plants can poison herbivores and, through the food chain, pose risks to humans and predators alike.

Threats to Wildlife

Wildlife, particularly in regions with high levels of mercury pollution, faces significant risks. Aquatic life is especially vulnerable, with fish and other organisms accumulating mercury in their tissues. This bioaccumulation not only affects individual species but also disrupts entire ecosystems. Birds and mammals that feed on contaminated fish or plants may suffer from mercury poisoning, leading to reproductive issues, behavioral changes, and death.

The recent floods will intensify these threats by spreading mercury across wildlife habitats. Aquatic species are now facing even higher levels of mercury exposure, as floodwaters concentrate the contamination in ponds, lakes, and rivers. Additionally, as floodwaters recede, they leave behind pools of mercury-contaminated water, creating concentrated hotspots of pollution that can devastate local wildlife populations. This will lead to a cascade of ecological disruptions, threatening the survival of various species and the balance of ecosystems.

Human Health Hazards

The most concerning impact of mercury use in ASGM is on human health. Miners are directly exposed to mercury during the milling and burning phases, leading to chronic mercury poisoning, characterized by neurological and cognitive impairments, kidney damage, and respiratory problems. The local communities are also at risk through the consumption of contaminated water, fish, and crops. Mercury exposure is particularly dangerous for pregnant women and children, as it can cause developmental delays, birth defects, and other severe health issues.

The flooding will significantly heighten these health risks, particularly in market areas where both milling and burning occur. As mercury spreads through floodwaters into residential areas, more people will be at risk of exposure through contaminated water and food sources. The health implications will be especially dire for vulnerable populations, including children, pregnant women, and the elderly, who are now facing an increased likelihood of mercury poisoning. The long-term health consequences will be devastating, with a potential rise in chronic illnesses and developmental issues within affected communities.

Conclusion

The environmental and health impacts of mercury use in artisanal and small-scale gold mining in Sudan will be profoundly exacerbated by the recent heavy rains and floods. Soil, water, air, vegetation, wildlife, and human health all suffer from the compounded effects of mercury contamination and extreme weather events. The torrents and floods will spread mercury far beyond the immediate mining areas, leading to widespread environmental degradation and escalating health crises.

Addressing these challenges requires a concerted effort to reduce mercury use, promote safer alternatives, and implement effective environmental and health protection measures, especially in the face of increasingly unpredictable and severe weather patterns. The sustainability of Sudan’s gold mining sector depends on balancing economic benefits with the urgent need to mitigate its environmental and health impacts in a changing climate.
