Theresa May has said at the One Planet Summit in Paris that the UK will host an international Zero Emission Vehicle Summit in Autumn 2018 which will gather industry leaders from across the world to promote the electric vehicle industry.
May's also announced funding of £140 million to boost to poorer communities around the world which are disproportionately affected by climate change.
Christian Aid's International Climate Lead, Mohamed Adow, said: "As the first country to industrialise, the UK has a moral duty to help the world's poorest people cope with the impacts of climate change they did not cause.
"It is good to see Theresa May putting some of the UK's money where her mouth is and committing to provide £140m of new funding to help poor communities on the front lines of climate change."
The UK government wants almost all cars and vehicles to have zero emissions by 2050, something Christian Aid support: "The UK is already a key hub for the manufacture of electric vehicles and it has the potential to be a true world leader in a technology that could reduce carbon emissions and cut fossil fuel use across the globe."
Adow added: "The UK is striking back at Donald Trump's misguided promotion of coal by leading the Powering Past Coal Alliance along with Canada and others."
Donald Trump didn't attend the conference.
Theresa May said in Paris on Tuesday: "By redoubling our efforts to phase out coal, as well as build on our world leading electric car production, we are showing we can cut emissions in a way that supports economic growth."
