We risk losing our battle against climate change unless we make the built environment more sustainable. That was the message I gave the audience at a Greening our Homes seminar arranged by the Policy Exchange Think Tank yesterday. It’s a stark message, but is backed up by the facts. Around half of all the carbon emissions the UK produces each year come from buildings, with our homes contributing 27% on their own. By contrast, only 15% come from our cars, so we could reduce our carbon emissions by a greater amount with a two-thirds cut in emissions from the residential sector than by taking all our cars off the road.
Yet, when compared to sustainable transport, like electric cars, or renewable forms of energy, the built environment gets scant mention. But if we’re committed to being the greenest government ever, we need to do it in the most practical and cost-effective way we can. That means buildings.
