After the world recovered from the Covid-19 pandemic with significant reliance on fossil fuels, carbon emissions surged to their greatest levels in history in 2021, with energy related emissions increasing 6% to 36.3 gigatonnes, according to a new report from the International Energy Agency (IEA).
Coal was the driving factor of the increase, accounting for more than 40% of the bounce in worldwide carbon emissions, which reached an all-time high of 15,3 billion tonnes. Energy-related emissions rose by nearly 2 billion tonnes, which marked the highest yearly increase.
