RIBA Architects say building demolitions cause of carbon emissions

Experts used to be proud to reduce emissions by replacing leaky old buildings with energy-efficient new ones.

Now the Royal Institute of British Architects says that was a mistake.

Instead, it says we should refurbish old buildings rather than scrap them, because of the pollution that would be involved in constructing a replacement building, otherwise known as embodied carbon.
