Immediate phase out of fossil fuels could keep warming below 1.5°C
Despite some positive climate action, new fossil fuel infrastructure is still being built and deployed. Dozens of new coal power plants are currently planned or under construction, for instance, while petrol car sales will nearly hit 100m in 2019.
But what if all that ceased tomorrow? It turns out that if we built no more fossil fuel infrastructure and instead replaced existing infrastructure at the end of its productive life with a zero carbon alternative we could limit peak temperature rise to 1.5°C – as long as we start now.
