Fossil fuel emissions are the dominant cause of rising global temperatures
Fossil fuels are responsible for a significant portion of global greenhouse gas emissions, with estimates ranging from 74% to over 75%. In 2018, 89% of global CO2 emissions were attributed to fossil fuels and industry. The combustion of fossil fuels for energy production, transportation, and industrial processes is a major contributor to these emissions.
CO2 emissions from fossil fuel combustion have seen notable fluctuations, with an 8% increase in 2022 relative to 2020 and a 1% rise compared to 2021. The COVID-19 pandemic caused a temporary decline in emissions due to reduced travel and economic activity in 2020. However, as economic activities rebounded in 2021 and 2022, emissions increased again.
The transportation sector, including cars, trucks, ships, trains, and planes, relies heavily on fossil fuels, with over 94% of transportation fuel being petroleum-based. This sector is the largest source of direct greenhouse gas emissions. Additionally, the commercial and residential sectors contribute to emissions by burning fossil fuels for heating and using gases for refrigeration and cooling in buildings.
The production and use of fossil fuels also have indirect environmental impacts. The extraction, processing, and transportation of fossil fuels disrupt ecosystems and destroy critical wildlife habitats.

Fossil fuel companies are huge polluters, advertising green energy while selling fossil fuels
Fossil fuels, including coal, oil, and natural gas, are the largest contributor to global climate change. Burning fossil fuels to generate electricity and heat is a significant source of greenhouse gas emissions, with carbon dioxide and nitrous oxide being the primary gases emitted. Fossil fuel companies have been identified as major polluters, and their continued extraction and sale of these products contribute significantly to global warming and climate change.
Despite the urgent need to transition to renewable energy, fossil fuel companies have been criticized for their advertising strategies that distract the public from the realities of their environmentally detrimental operations. These companies engage in greenwashing, where they mislead consumers by promoting their investments in clean energy and low-carbon projects while simultaneously expanding their core businesses of oil, gas, and coal. For example, in 2019, BP spent millions on an advertising campaign highlighting its commitment to low-carbon energy and cleaner natural gas. However, the reality is that BP continues to allocate the majority of its annual expenditure to oil and gas, with minimal investments in renewable energy sources.
The Greenwashing Files, launched by ClientEarth, analyzed the advertising claims of some of the world's biggest fossil fuel companies and found that their publicity often misrepresented the sustainability of their activities. These companies underreported their greenhouse gas emissions, overemphasized their clean energy investments, and promoted commercially unproven "solutions" to continue their fossil fuel production. Additionally, they publicized "net-zero" ambitions and sustainability targets that were not aligned with the Paris Agreement goals, often including loopholes that allowed for increased fossil fuel operations.
Fossil fuel companies have also utilized social media, specifically Twitter, to communicate their renewable energy projects and showcase their efforts in adopting renewable technologies. Companies like Shell, ExxonMobil, BP, and TotalEnergies tweet about renewables such as solar, biofuels, and hydrogen to shift the conversation away from their ongoing fossil fuel production. This strategic discourse aims to delay the transition to a renewable future and maintain their profits from the extraction and sale of fossil fuels.
While fossil fuel companies claim to be trusted partners in society's transition to cleaner energy, their actions often contradict their advertising messages. The continued extraction and sale of fossil fuels contribute to global warming, species extinction, and the disruption of natural balances, posing risks to human beings and all other forms of life on Earth. As such, there is a growing call for these companies to change their business models and for investors to move away from fossil fuels toward clean energy alternatives.
