According to calculations by the US think tank Energy Innovation, a second term of US President Donald Trump could almost completely undo the progress made in US climate policy. If Trump implemented the climate policy elements of „Project 2025,“ annual emissions would still amount to 4.92 gigatons of CO2 equivalents in 2030. However, if the current US policy continues, emissions would fall to 4.14 gigatons in 2030. The difference is greater than Germany’s total emissions of 0.67 gigatons of CO2 equivalents in 2023.
