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.
While crude oil and natural gas are also being phased out in chemical processes (e.g. production of new building blocks for plastics) as the circular economy and biobased economy (e.g. bioplastics) are being developed [16] to reduce plastic pollution, the fossil fuel phase out specifically aims to end the burning of fossil fuels and the consequent production of greenhouse gases.
Natural gas (mostly methane) is an even more potent greenhouse gas when it escapes into the atmosphere prior to being burned. Since the industrial age began circa 1750–1850 with growing wood and coal use, the atmospheric concentration of carbon dioxide and methane have increased about 50% and 150%, respectively, above their relatively stable ...
Global fossil fuel consumption and energy emissions hit all-time highs in 2023, even as fossil fuels' share of the global energy mix decreased slightly on the year, the industry's Statistical ...
Fossil fuel CO 2 emissions on log (natural and base 10) scales. The graphic shows the logarithm of 1850–2019 fossil fuel CO 2 emissions; [85] natural log on left, actual value of Gigatons per year on right. Although emissions increased during the 170-year period by about 3% per year overall, intervals of distinctly different growth rates ...
As of 2019, 37% of global electricity is produced from low-carbon sources (renewables and nuclear energy). Fossil fuels, primarily coal, produce the rest of the electricity supply. [160] One of the easiest and fastest ways to reduce greenhouse gas emissions is to phase out coal-fired power plants and increase renewable electricity generation. [136]
China produces 31% of global fossil fuel CO2 emissions. The new report cited some bright spots, with emissions in the U.S. and European Union both falling, driven in part by coal plants being retired.
However, gas venting and unintended fugitive emissions throughout the supply chain can result in natural gas having a similar carbon footprint to other fossil fuels overall. [11] Natural gas can be found in underground geological formations, often alongside other fossil fuels like coal and oil (petroleum). Most natural gas has been created ...
