What You'll Learn
Fossil fuel companies vs consumers
Fossil fuels are a group of energy resources that include coal, oil, and natural gas. They are formed from the decomposition of carbon-based organisms that died millions of years ago. The burning of fossil fuels releases large amounts of carbon dioxide (CO2), a greenhouse gas, into the atmosphere, contributing to global warming and climate change.
Fossil fuel companies play a significant role in pollution and climate change. A report by the Guardian states that just 100 companies, including ExxonMobil, Shell, BP, and Chevron, have been responsible for more than 70% of the world's greenhouse gas emissions since 1988. These companies have continued to invest heavily in oil and gas, despite advertising campaigns promoting low-carbon energy and cleaner natural gas. For instance, in 2019, BP spent millions on advertising its low-carbon initiatives, while over 96% of its annual expenditure was still focused on oil and gas. Fossil fuel companies are also responsible for enormous volumes of wastewater, which can be contaminated with heavy metals, radioactive materials, and other pollutants, posing risks to human health and the environment.
On the consumer side, individuals contribute to pollution through their daily activities, such as driving cars and using electricity. The transportation sector is the largest source of direct greenhouse gas emissions, with over 94% of the fuel used for transportation being petroleum-based, resulting in emissions from burning gasoline and diesel. Additionally, electricity production, which is often powered by burning fossil fuels, contributes to emissions. Consumers can play a role in reducing pollution by conserving energy, using energy-efficient products, and opting for renewable energy sources.
While individual actions are important, addressing the pollution and emissions caused by fossil fuel companies is crucial. The Carbon Majors Report highlights the significant impact of a small number of fossil fuel producers on climate change. It emphasizes the need for transparency among these companies and for investors to recognize the risks associated with their fossil fuel holdings. As such, investors are encouraged to move away from fossil fuels and towards clean energy alternatives.

Fashion industry emissions
The fashion industry is a major contributor to climate change, ranking as the third most polluting industry globally. It is responsible for about 10% of global carbon emissions annually, more than all international flights and maritime shipping combined. This figure is projected to increase, with the industry potentially accounting for 26% of global carbon emissions by 2050 if no changes are made. The industry's large carbon footprint is driven by several factors, including fabric production, manufacturing processes, and transportation.
Fabric production, particularly the use of synthetic fibres like polyester, has a significant environmental impact. Polyester, the most widely used clothing fibre, requires 1.3 billion barrels of oil annually for its production and can create carbon emissions up to three times those generated by manufacturing cotton. Synthetic fibres also contribute to microplastic pollution, as washing these garments releases microplastics into waterways, eventually reaching the oceans.
Manufacturing processes, often located in developing countries, rely on coal-powered plants, further increasing the carbon footprint of garments. The pressure to keep up with trends leads to continuous garment production and a cycle of buying and discarding clothing, exacerbating the industry's environmental impact.
To address these issues, there is a growing focus on sustainable fashion and international cooperation. Initiatives like the Fashion Industry Charter for Climate Change aim for net-zero emissions by 2050 within the fashion industry. Additionally, legislation such as New York's Fashion Act seeks to hold brands accountable by requiring them to map their supply chains and disclose their environmental and social impacts. Consumers are also encouraged to move away from fast fashion, buying fewer but higher-quality, sustainable pieces.
While the fashion industry plays a significant role in pollution, it is important to recognize that corporations are the primary culprits of climate change. Just 100 companies have been responsible for 71% of global greenhouse gas emissions, and the focus should be on their accountability and structural changes to combat climate change effectively.

Food retail waste
Food waste is a significant contributor to global carbon emissions, with an estimated 8 to 10% of global GHG emissions stemming from food waste alone. Retailers play a pivotal role in this issue, as they are responsible for a substantial portion of the food waste generated. In the United States, for instance, the grocery retail sector produces nearly six million tons of unsold food annually, with 38% of food going unsold or uneaten.
Grocery retailers face challenges in managing food waste due to high customer expectations for variety, quality, and freshness. This often leads to the disposal of edible food based on aesthetic standards or misinterpretation of expiration dates. However, retailers are increasingly recognizing the importance of reducing food waste and are exploring various strategies to optimize their operations.
One approach is to partner with technology providers to implement intelligent routing, temperature monitoring, early spoilage detection, and precise product sorting to minimize waste. Retailers are also exploring dynamic pricing and promotions to incentivize shoppers to purchase items nearing their expiration dates, such as through startups like Wasteless and Too Good To Go. Additionally, retailers are working to educate consumers about responsible consumption and providing information on food storage and preparation to reduce waste at home.
Some countries have also taken legislative action to address food waste. For example, France introduced a law in 2016 prohibiting supermarkets from discarding edible food, instead requiring them to donate it to those in need. This dual approach of industry initiatives and governmental regulations is crucial in mitigating food retail waste and its environmental impact.
While consumers are often encouraged to make sustainable choices, it is essential to recognize that corporations hold a significant responsibility for climate change. Since 1988, just 100 companies have been responsible for 71% of global greenhouse gas emissions. Thus, addressing the actions of these major polluters is vital to tackling the climate crisis effectively.

Transport emissions
Transport is a major contributor to global carbon emissions, responsible for about one-fifth of the world's CO2 output. In the US, the transportation sector accounted for the largest portion (28%) of total US GHG emissions in 2022. Cars, trucks, commercial aircraft, and railroads are among the sources contributing to transportation sector emissions. Passenger travel, including cars, bikes, and buses, makes up 60% of these emissions, while the remaining 40% come from freight and logistics.
The transport sector's dependence on fossil fuels is a significant factor in its carbon footprint. Motorised transport on land, sea, and air relies heavily on internal combustion engines that use liquids or natural gas as fuel. While there has been a slight increase in the use of biofuels, the sector still depends on oil products for nearly 91% of its energy. This has led to a growing focus on electrifying road vehicles and improving fuel economy. About 50 countries have implemented fuel economy and/or vehicle efficiency standards for light-duty vehicles, and nearly 40 have similar standards for medium and heavy-duty vehicles.
To reduce transport emissions, governments and organisations have introduced various initiatives. The US EPA, for example, has worked to reduce GHG emissions from the transportation sector through joint rule-making with DOT. They have set standards for vehicles that emit less harmful greenhouse gases, encouraging manufacturers to improve fuel efficiency and consumers to make environmentally friendly purchases. Additionally, the 2007 Energy Independence and Security Act requires federal agencies to acquire low-emission vehicles, contributing to a greener federal fleet over time.
The IEA's Net Zero Scenario aims for a significant reduction in transport sector emissions by 2030, encouraging the use of less carbon-intensive travel options and more efficient technologies. Strong regulations, fiscal incentives, and infrastructure investments will be crucial to achieving these goals and transitioning to low- and zero-emission vehicles.

Deforestation and agriculture
Agriculture is a significant contributor to deforestation, with 60 to 80% of tropical deforestation attributed to it. This involves clearing forests to make room for crops, livestock, and paper production. The expansion of pastureland for cattle grazing and beef production is a leading driver of deforestation, especially in Brazil, where it is responsible for the majority of forest loss. In addition, soy production, which is used to feed livestock, has also contributed significantly to deforestation in Brazil and other regions.
The demand for meat and agricultural products is increasing globally, and this shift in diet towards greater meat consumption is a significant driver of deforestation. As consumers, one of the most effective ways to combat deforestation is to reduce meat consumption, especially beef and other livestock raised on cleared rainforest land. Additionally, consumers can advocate for and support companies that adopt zero-deforestation policies and commit to avoiding deforestation and degradation in their supply chains.
Industrial activities such as logging and mining are also major contributors to deforestation. Logging activities, often facilitated by the construction of roads and other infrastructure, have led to significant forest loss, particularly in the Amazon, Southeast Asia, and sub-Saharan Africa. Mining operations, especially in Brazil, Ghana, Indonesia, and Suriname, have had alarming environmental fallout, with one-third of mining-related deforestation in the last two decades occurring in just the last five years.
Infrastructure development, including transportation and energy infrastructure, is another significant driver of deforestation. Poorly planned infrastructure can lead to severe environmental damage, including the fragmentation and destruction of forest and freshwater habitats, interruption of wildlife migration routes, erosion, and air and land pollution. As countries develop and their economies grow, the demand for resources and land can lead to deforestation, particularly in low-to-middle-income nations.
To address deforestation caused by agriculture and industry, various solutions are being implemented. The WWF, for example, works with companies that depend on forests to strengthen certification standards for forest-based products through the Forest Stewardship Council (FSC) system. They also engage with agricultural organizations to ensure responsible land management and prevent encroachment on forests. Additionally, regenerative agriculture, also known as carbon farming, offers a more sustainable way to produce food while sequestering carbon in the soil. Agroforestry practices, such as planting riparian buffers, can restore ecosystems and reduce the impacts of flooding and water pollution.

Frequently asked questions
The fossil fuels sector is the most polluting industry in the world, with other major polluting industries including fashion, transport, food retail, and electronics.
Consumers have a relatively small impact on pollution compared to corporations. Since 1988, just 100 companies have been responsible for 71% of global greenhouse gas emissions. Consumers are often encouraged to make changes in their everyday lives to tackle climate change, but this ignores the main culprit of emissions: corporations.
The focus on consumer behaviour can misplace responsibility for GHG emissions onto individual consumers, ignoring the disproportionate climate impact of corporate interests. For example, the average American household produces only 8.1 metric tons of carbon dioxide out of a total of over 33 billion tons globally. Blaming consumers can also let fossil fuel companies off the hook, as they have led the charge on climate change denial and spread false perceptions.
