Natural gas is often described as the cleanest fossil fuel, producing less carbon dioxide per joule delivered than either coal or oil, [50] and far fewer pollutants than other fossil fuels. However, in absolute terms, it does contribute substantially to global carbon emissions, and this contribution is projected to grow.
Burning fossil fuels: Burning oil, coal and gas is estimated to have emitted 37.4 billion tonnes of CO 2-eq in 2023. [34] The largest single source is coal-fired power stations, with 20% of greenhouse gases (GHG) as of 2021. [35] Land use change (mainly deforestation in the tropics) accounts for about a quarter of total anthropogenic GHG ...
The burning of fossil fuels has a number of negative externalities – harmful environmental impacts where the effects extend beyond the people using the fuel. These effects vary between different fuels. All fossil fuels release CO 2 when they burn, thus accelerating climate change.
But carbon pollution from burning fossil fuels has risen 1% on 2021 levels, the analysis from the Global Carbon Project says, and is now slightly above the record levels seen in 2019.

This phenomenon is popularly known as global dimming, [133] and is primarily attributed to sulfate aerosols produced by the combustion of fossil fuels with heavy sulfur concentrations like coal and bunker fuel. [53] Smaller contributions come from black carbon (from combustion of fossil fuels and biomass), and from dust.
The burning of fossil fuels and cement production are the main reasons for the increase in atmospheric CO 2 since the beginning of the industrial era. [ 10 ] Other human-caused changes in the atmospheric carbon cycle are due to anthropogenic changes to carbon reservoirs.
An estimated 5.13 million deaths per year globally are attributable to air pollution from fossil fuel use that could be avoided by phasing them out.
