About a quarter of the world’s electricity currently comes from power plants fired by natural gas. These contribute significantly to global greenhouse gas emissions (amounting to 10% of energy-related emissions according to the most recent figures from 2017) and climate change. By gathering data from 108 countries around the world and quantifying the emissions by country, a team has estimated that total global carbon dioxide (CO2) emissions from the life cycle of gas-fired power is 3.6 billion tonnes each year. They found that this amount could be reduced by as much as 71% if a variety of mitigation options were used around the world.
