Who Is The Worst Corporate Polluter?

The world's most polluting company is a contentious topic, with various sectors and industries contributing significantly to global carbon emissions. However, the fossil fuel industry consistently ranks as the most polluting, with new data revealing that 20 fossil fuel companies are directly linked to over a third of all greenhouse gas emissions. Notably, 100 companies have been responsible for 71% of global emissions since 1988, with ExxonMobil, Shell, BP, and Chevron among the highest emitters. The leading state-owned polluter, Saudi Aramco, has produced 4.38% of carbon dioxide and methane since 1965. Other polluting industries include agriculture, fashion, and construction, with the fashion industry contributing about 10% of our annual carbon footprint.

Fossil fuel companies

The fossil fuel industry has long been aware of the dangers of rising global temperatures and their contribution to climate change. Investigations have revealed that companies like Exxon and Koch Industries have funded climate deniers to confuse the public and delay action. Despite the urgent need to reduce emissions, fossil fuel companies are driven by short-term profitability, risking wasting trillions of dollars by continuing to pursue coal, oil, and gas projects.

A 2021 report by the Carbon Disclosure Project (CDP), a non-profit organization, revealed that just 100 companies, including ExxonMobil, Shell, BP, and Chevron, have been responsible for 71% of global GHG emissions since 1988. These companies have contributed significantly to climate change and continue to extract and burn fossil fuels at an alarming rate, threatening the lives of millions.

The transition to renewable energy is crucial to stabilizing our climate. However, fossil fuel companies are spending billions to lock in more climate pollution, even as they face scrutiny and pressure to accelerate their environmental strategies. As public awareness grows, companies like BP have withdrawn their greenwashing advertisements, but much more urgent action is needed to address the climate crisis caused by these polluting industries.

Construction

Volatile organic compounds (VOCs) are another significant air pollutant in construction sites. These compounds, found in fuels, paints, and solvents, can cause various health issues, including headaches, organ damage, and cancer. Additionally, asbestos fibers released during construction can remain in the air for extended periods, posing serious health risks when inhaled. Noise pollution is also a concern, impacting both construction workers and local residents, and leading to stress, sleep disturbances, and high blood pressure.

Water pollution is another issue in construction, with sediment runoff, chemical spills, and improper waste disposal contaminating nearby water bodies. Fuel leaks and spills can be particularly costly to clean up and have negative consequences for aquatic life and water quality. Soil pollution caused by petroleum products and asbestos-containing materials further adds to the environmental impact of construction activities.

To reduce their environmental impact, construction companies should adopt sustainable practices, use pollutant-free building materials, and minimize the discharge of pollutants. Financial incentives and regulations, such as the 'polluter pays' principle, can encourage companies to prioritize pollution prevention and sustainable practices. Air quality monitoring solutions and strict protocols can also help construction sites manage their pollution output.

Fashion

The fashion industry is responsible for significant environmental pollution, with fast fashion companies being some of the biggest contributors. Fast fashion is defined by its constant provision of new styles at very low prices, and its mass production, low prices, and high sales volumes. The ever-growing throwaway culture it promotes generates an estimated 92 million tonnes of textile waste globally every year, and this is expected to increase to 134 million tonnes by 2030.

Some of the biggest fast fashion companies responsible for environmental pollution include Shein, Zara, Forever 21, H&M, Uniqlo, Fashion Nova, and PrettyLittleThing. These companies have been criticised for their rapid production and trend cycles, ultra-fast turnaround times, and social media marketing strategies that encourage consumers to buy more and dispose of clothing after only a few wears. For example, Shein adds at least 500 new products to its website daily and has garments ready to be sold in just 10 days, while Zara releases 24 collections per year.

The environmental impacts of these companies include textile waste, water pollution, carbon emissions, and labour rights violations. Textile dyeing is the world's second-largest polluter of water, and the fashion industry is responsible for 20% of industrial water pollution worldwide. It is also the second-biggest consumer of water, with high water usage in the production of cotton garments. The industry contributes to nearly 10% of global carbon emissions, and microplastics from synthetic textiles further contribute to ocean pollution.

To address these issues, consumers and retailers are promoting sustainable fashion practices, such as slow fashion, which focuses on the production and sale of sustainable clothing created with eco-friendly materials. Organisations in Geneva and beyond are also working towards a shift to sustainable fashion and fostering international cooperation on the issue. The European Commission has presented a strategy to make textiles more durable, repairable, reusable, and recyclable, and the EU has developed an Ecolabel for producers that respect ecological criteria.

Livestock production

One of the main issues with livestock production is that consumers have become spatially disconnected from the processes involved in producing animal products. This disconnect leads to a lack of awareness about the environmental impact of consuming these products. The trend of increasing consumption of animal products, particularly in developing countries, has a negative impact on ecosystems and water sources. Livestock production processes are the biggest culprits in farm emissions, generating 4 billion tons of CO2eq in 2018 and contributing to widespread deforestation.

In addition to air and water pollution, livestock production also has other environmental impacts. It requires crop production for animal feed, and long-term meat preservation methods can further contribute to environmental degradation. Certain ecosystems, such as arid and semi-arid lands, are better suited for livestock production as they are more efficient and rational in utilizing land resources. However, the overall environmental impact of the livestock industry is significant, and it is important for consumers to be aware of the consequences of their food choices.

While there is growing awareness about the environmental impact of livestock production, legislative and regulatory efforts to address this issue have faced challenges. In the United States, for example, Congress has exempted livestock producers from reporting air emissions to federal authorities, hindering progress in reducing emissions from this industry. Despite these setbacks, some states are taking initiatives to monitor and regulate livestock emissions. Additionally, the development of sustainable practices, such as regenerative agriculture or carbon farming, offers more environmentally friendly ways to produce food while sequestering carbon in the soil.

Oil and gas companies

The report names ExxonMobil, Shell, BP, and Chevron as among the highest-emitting investor-owned companies since 1988. These companies have faced criticism for their environmental records and their role in perpetuating the climate crisis. Despite the growing pressure to reduce emissions and transition to renewable energy, some oil and gas companies have continued to pursue coal, oil, and gas projects, risking wasting trillions of dollars in the face of international climate action and the rise of renewables.

The leading state-owned polluter, Saudi Aramco, has produced 4.38% of all carbon dioxide and methane since 1965. The Carbon Majors Report also highlights that 32% of emissions come from public investor-owned companies, emphasizing the responsibility of investors in driving the transition to a sustainable economy. Oil and gas companies are beginning to recognize the need for change, with some making green investments and exploring carbon capture and storage technologies. However, for many, the investments and pace of change are not considered sufficient to address the climate emergency.

The future of the oil industry is uncertain, and investors face a choice between managing its decline and reinvesting in sustainable industries or risking stranded assets as the world moves towards clean energy. The Carbon Tracker study in 2015 highlighted the economic risks associated with continued investment in fossil fuel companies, and more and more large corporations are committing to renewable energy sources.
