Electric vehicles produce less carbon dioxide than petrol cars across the vast majority of the globe – contrary to the claims of some detractors, who have alleged that the CO2 emitted in the production of electricity and their manufacture outweighs the benefits. The finding is a boost to governments, including the UK, seeking to move to net zero carbon emissions, which will require a massive expansion of the electric car fleet. A similar benefit was found for electric heat pumps. In the UK, transport is now the biggest contributor to the climate crisis and domestic heating has been stubbornly stuck on natural gas for much of the country. In the UK, the savings are about 30%. However, that is likely to improve further as electric vehicles grow even more efficient and more CO2 is taken out of the electricity generating system. Heat pumps use electricity and heat exchange systems – similar in principle to those found in fridges – to take advantage of the difference in temperature underground and at the surface, in the case of ground source heat pumps, and between the outdoor air and indoors in the case of air source heat pumps. If they were widely used, the study found, they could reduce global carbon emissions by up to 0.8 gigatons a year by 2050, or the equivalent of Germany’s emissions today. “The idea that electric vehicles or heat pumps could increase emissions is essentially a myth,” said Florian Knobloch of Nijmegen University in the Netherlands, the lead author of the study. “We’ve seen a lot of disinformation going around. Here is a definitive study that can dispel those myths.”

Switching to an electric car in most parts of the world will cut emissions, according to new research that debunks claims electric vehicles (EVs) are only greener if powered by renewable electricity. Researchers at Radboud University in the Netherlands concluded electric cars are almost always greener than petrol cars, even when fossil fuels are used to generate most of the electricity needed to charge them. Only in countries heavily reliant on the dirtiest fuels like coal or oil – such as in India, Poland or the Czech Republic – is it better for the environment to drive a petrol car, the study published in the journal Nature Sustainability concluded.
