Cycling is ten times more important than electric cars for reaching net-zero cities. Globally, only one in 50 new cars were fully electric in 2020, and one in 14 in the UK. Sounds impressive, but even if all new cars were electric now, it would still take 15-20 years to replace the world’s fossil fuel car fleet. The emission savings from replacing all those internal combustion engines with zero-carbon alternatives will not feed in fast enough to make the necessary difference in the time we can spare: the next five years. Tackling the climate and air pollution crises requires curbing all motorised transport, particularly private cars, as quickly as possible. Focusing solely on electric vehicles is slowing down the race to zero emissions. This is partly because electric cars aren’t truly zero-carbon – mining the raw materials for their batteries, manufacturing them and generating the electricity they run on produces emissions. Transport is one of the most challenging sectors to decarbonise due to its heavy fossil fuel use and reliance on carbon-intensive infrastructure – such as roads, airports and the vehicles themselves – and the way it embeds car-dependent lifestyles. One way to reduce transport emissions relatively quickly, and potentially globally, is to swap cars for cycling, e-biking and walking – active travel, as it’s called.

An “elite minority” of frequent flyers cause most of the climate damage resulting from aviation’s emissions, according to an environmental charity. The report, which collates data from the countries with the highest aviation emissions, shows a worldwide pattern of a small group taking a large proportion of flights, while many people do not fly at all. In the US, 12% of people took 66% of all flights, while in France 2% of people took half of the flights, the report says. In China 5% of households took 40% of flights and in India just 1% of households took 45% of all the flights.

Bill Gates and the billionaire behind the mobile network Three, Li Ka-Shing, have invested a further $24m into a hydrogen plane start-up. ZeroAvia, which is based in Cranfield and also has backing from the government, is working on a hydrogen powered propulsion system that will ultimately allow aircraft with up to 50 passengers.

A 50-seat hydrogen-powered plane will take to the skies in as little as five years under plans backed by British Airways to eliminate emissions on short-haul flights. It could eventually replace jet-fuel aircraft on domestic and some European flights.
