Climate scientists are shining a light on an important question: Over the last century cars have shaped our cities. We’ve gone from cobbled streets, to 18 lane super highways. But now scientists are worried. Health experts are telling us that vehicle exhaust fumes are making us sick. And climate experts are telling us we’re burning too many fossil fuels. Countries like France and the UK are trying to fix things by banning the sale of new petrol and diesel vehicles by 2040. But there’s a major problem with these bans. They’re set to happen That’s professor Peter Newman. He’s a climate scientist shining a light on the problem. While some car companies claim that fossil fuel cars will be around for a long time, the science says that’s bad idea. Experts say to stop dangerous levels of climate change, wealthy countries must Such a huge switch won’t be easy. But the good news is some countries are already well on their way. Take Norway. Their schemes to get people to buy electric vehicles have been so successful that Also, Norway is banning new petrol and diesel cars by 2025. That’s 15 years earlier than in France and the UK. To reduce pollution, Norway’s capital has created car free zones to get people to walk and cycle too. Norway isn’t perfect. It’s still exporting lots of oil and gas. But if more countries followed its example on phasing out polluting cars, we’d be in a much better position. And we’d be even better off if governments scaled up public transport and made it easier for us to walk and cycle too. Record-breaking heat waves and wildfires this year have shown us just how urgently we need to cut all sources of greenhouse gases.
