Just how damaging for the environment is our use of fossil fuels?
Fossil fuels, which include coal, oil, and natural gas, are the primary contributors to global greenhouse gas emissions. When burned, these fuels release vast amounts of carbon dioxide (CO₂) and other greenhouse gases. The accumulated emissions lead to an enhanced greenhouse effect, trapping more heat in the atmosphere and causing global temperatures to rise. Current data indicates that about 91% of global greenhouse gas emissions are a result of fossil fuel emissions.
Furthermore, the extraction, transportation, and burning of fossil fuels result in severe environmental degradation. This includes habitat destruction, air and water pollution, and oil spills, harming fragile ecosystems. What’s more is that air pollutants from fossil fuel combustion, such as sulfur dioxide and nitrogen oxides, lead to smog formation and respiratory illnesses in human populations.
“ Repeatedly, climate experts have underscored the imperative of reducing our dependence on detrimental fossil fuels, advocating for a move toward renewable energy. The IPCC has urgently appealed to nations to expedite their transition from burning fossil fuels. They highlight that emissions from current and proposed fossil fuel infrastructures will notably exceed the emission limits set to contain global warming to 1.5 degrees Celsius. Achieving net zero requires slashing fossil fuel demand by 80% by 2050, coupled with effective carbon removal measures. ”
Considering the detrimental effects of burning fossil fuels, the solution appears straightforward: eliminate fossil fuel usage to protect the climate. However, the complexities of energy infrastructure and global dependence on these fuels mean that the transition is not as simple as it seems.
