The world's most polluting companies are often those involved in the fossil fuel industry. Research has shown that just 20 companies, mostly state-owned, have contributed to 35% of all energy-related carbon dioxide and methane emissions worldwide, totalling 480 billion tonnes of carbon dioxide equivalent since 1965. Leading climate scientists have called on politicians to take urgent measures to rein in their activities. These companies have been accused of delaying national and global action and thwarting the shift to a low-carbon future. Some of the highest emitting investor-owned companies include ExxonMobil, Shell, BP, and Chevron. However, it's important to note that other industries, such as agriculture, fashion, and construction, also contribute significantly to global pollution levels.

Fossil fuel companies
The top 20 polluting companies, including state-owned and multinational firms, have contributed to 35% of all energy-related carbon dioxide and methane emissions worldwide, totaling 480 billion tonnes of carbon dioxide equivalent since 1965. The leading state-owned polluter, Saudi Aramco, has produced about 4.38% of global carbon dioxide and methane emissions during this period. These companies have been aware of the threat of climate change posed by their products since the 1950s but have often disputed these claims and worked to delay action.
The burning of fossil fuels releases large amounts of carbon dioxide, a greenhouse gas that traps heat in the Earth's atmosphere, leading to global warming and climate change. Fossil fuels are currently responsible for about 80% of the world's energy supply and include coal, oil, and gas. Coal is the dirtiest fossil fuel, contributing the most to the increase in global temperatures. Oil releases significant carbon when burned, accounting for about a third of the world's total carbon emissions. Natural gas, while cleaner than coal and oil, is still a fossil fuel and contributes to a fifth of total carbon emissions.
The fossil fuel industry's impact extends beyond carbon pollution and climate change. The extraction and burning of fossil fuels cause local air pollution, with particulate matter (PM2.5) from soot small enough to enter the bloodstream, increasing the risk of stroke, heart disease, lung cancer, and respiratory illness. Additionally, the upstream oil and gas industry has one of the highest rates of severe injuries, and coal miners face health issues like black lung disease.

Oil and gas companies
These companies have been accused of delaying, controlling, or blocking policies addressing climate change, and their operations have had detrimental effects on wildlands and communities. Oil and gas drilling disrupts wildlife, damages public lands, and generates pollution and air pollution, which poses significant health risks, including respiratory and cardiovascular diseases. Additionally, fossil fuel development can leak toxic substances into the soil and water sources, causing cancer, birth defects, and liver damage. Disproportionately impacted communities include Black, Brown, Indigenous, and low-income groups, who often live in more polluted areas.
Some of the top-polluting oil and gas companies include ExxonMobil, Shell, BP, and Chevron. These companies have made efforts to improve their environmental impact, such as investing in carbon capture and storage technologies and renewable energy projects. However, critics argue that these companies have been aware of the threat their products pose to the climate since the 1950s and have continued to expand their operations, prioritising profits over the planet.
As a result, organisations like the Climate Accountability Institute aim to hold these companies accountable and shift the focus from individual responsibility to corporate accountability. With the knowledge that the fossil fuel industry has contributed significantly to climate change, there is a growing movement towards renewable energy sources and a decline in the oil industry.

State-owned companies
A notable example is Saudi Aramco, which has been identified as the leading state-owned polluter, having produced 4.38% of global carbon dioxide and methane emissions since 1965. Other state-owned companies with significant emissions include Gazprom and Coal India, which have been responsible for over 3% and 3% of global emissions, respectively.
These state-owned companies have continued to expand their operations despite being aware of the detrimental effects of their industries on the planet. They have contributed to the climate emergency, with some sources indicating that just 20 state-owned and multinational companies are driving the crisis threatening humanity.
While some companies have disputed claims regarding their environmental impact, there is a growing recognition of the need to hold these entities accountable for their role in climate change. Researchers and organizations like the Climate Accountability Institute aim to shift the focus from individual responsibility to ensuring that companies most responsible for carbon emissions are held accountable for their actions.

Energy companies
The top 20 polluting companies, including 12 state-owned enterprises, have contributed to approximately 35% of all energy-related carbon dioxide and methane emissions worldwide, totalling about 480 billion tonnes of carbon dioxide equivalent since 1965. The leading state-owned polluter, Saudi Aramco, has produced about 4.38% of global carbon dioxide and methane emissions during this period.
Many of these energy companies have spent millions lobbying governments and delaying or blocking policies addressing climate change. However, there is a growing trend of companies investing in renewable energy sources. For example, Shell established a renewables arm in 2015 with a $1.7 billion investment, and Chevron is investing in carbon dioxide injection projects to capture and store carbon.
Electricity producers are also significant contributors to pollution, with companies like Duke Energy, Southern Co., and American Electric Power being listed as some of the largest carbon polluters. While some still rely heavily on coal, the dirtiest fossil fuel, there is a shift towards renewables as solar and wind power become more cost-effective. For instance, NextEra Energy and Berkshire Hathaway Energy obtain nearly a quarter of their electricity from renewable sources.
Overall, energy companies, particularly those in the fossil fuel industry, have played a substantial role in driving climate change and must be held accountable for their actions.

Fashion industry
The fashion industry has a significant impact on the environment, particularly in terms of pollution. Fast fashion, which involves the constant provision of new styles at very low prices, has been identified as a major contributor to this issue. The fast fashion business model relies on the rapid exploitation of resources and human labour to deliver garments following the latest trends, resulting in a significant amount of waste and pollution.
One of the main environmental concerns associated with the fashion industry is water pollution. Textile dyeing is considered the world's second-largest polluter of water, as the water leftover from the dyeing process is often dumped into ditches, streams, or rivers. The industry is also responsible for drying up water sources, with fashion production requiring massive amounts of water. It is estimated that producing a single cotton t-shirt requires 700 to 2700 litres of freshwater, enough to meet one person's drinking needs for up to 2.5 years.
Another issue is the use of synthetic fibres such as polyester, nylon, and acrylic, which take hundreds of years to biodegrade. When these synthetic textiles are washed, they release microplastic fibres that contribute to water pollution and can end up in the food chain. A single laundry load of polyester clothes can discharge 700,000 microplastic fibres. The International Union for Conservation of Nature (IUCN) estimated in 2017 that 35% of all microplastics found in the ocean come from laundering synthetic textiles.
The fashion industry also contributes to air pollution and greenhouse gas emissions. It is estimated that fashion production accounts for about 10% of total global carbon emissions, equivalent to the emissions generated by the entire European Union. The industry's reliance on fossil fuel-based energy for energy-intensive processes contributes to this impact. Additionally, the fashion industry has been associated with land degradation, particularly in developing nations where garment industries are often located due to cheap labour and lenient laws and regulations.
To address these environmental concerns, there have been calls for a shift towards "slow fashion," which prioritises sustainable and ethical practices over excessive production and consumption. Organisations like the World Resources Institute advocate for business models that reuse clothes and maximise their useful life. The European Commission has also proposed strategies to make textiles more durable, repairable, reusable, and recyclable, and to hold companies accountable for minimising their carbon and environmental footprints.
