With air pollution causing a fifth of deaths in Nepal, growing EV use could add nearly three years to Kathmandu residents’ lives

In a rundown hangar in the heart of Kathmandu, the remains of a dozen electric trolley buses stand abandoned and corroding. Caked in dust and bird-droppings and lined with rubbish, they are a reminder of a bold experiment, launched 50 years ago, to electrify the city’s public transport system. Down the side of one is written, “Keep me alive”.

Today, that plea is being heard. More than 70% of four-wheeled passenger vehicles – largely cars and minibuses – imported into Nepal last year were electric, one of the highest rates in the world. The figure reflects a remarkable growth in the use of electric vehicles (EVs), which saw the country import more than 13,000 between July 2023 and 2024, up from about 250 in 2020-21.

In Sweden, most residential heating and hot water comes from heating networks – helping to pool resources and innovation

District heating is sometimes talked about like some kind of unattainable utopia, but in the Swedish capital these low-carbon heating networks are not special.

In fact, district heat is so run-of-the-mill that many Stockholmers do not know that they have it, said Fredrik Persson, as he showed the Guardian around Stockholm Exergi’s pioneering power station in Norra Djurgårdsstaden, a former port and industrial area.
