The Earth is edging ever closer to a point of no return, with a joint statement issued during the COP24 climate conference calling for “decisive action” on climate change within the next two years. Most nations have taken on the challenge to switch from a reliance on fossil fuels to a sustainable energy system – some faster than others. A recent Carbon Brief report written by E4tech and Imperial College London and published by Drax has ranked 25 major world economies on their efforts (or lack thereof) in the transition to clean energy.

Green and clean: Clean electricity underpins almost all efforts to shift towards a decarbonized future. In 2017, the global average carbon intensity of electricity was 450 gCO2/kWh. Of the 16 major countries below that average, the United Kingdom showed the fastest transition to decarbonization.
