Building new roads increases traffic, leading to more carbon emissions. The Government claims new roads will not significantly increase emissions so we decided to find out using their own data. We used Freedom of Information laws to ask Highways England for each of the fifty RIS2 schemes carbon impact. So far we have data for 40 out of the 50 listed schemes, which reveals that Highways England estimate the extra traffic will lead to over 23 million tonnes of extra carbon emissions, whilst construction adds another 3 million tonnes.
We’ve also requested more construction emissions but are still waiting for most of these.
