Stop demolishing buildings, say engineers

 The Royal Academy of Engineering, which one might have expected to have an interest in lots of new building, has set that aside in the interests of reducing carbon dioxide emissions. BBC reports:
Britain’s top engineers are urging the government to stop buildings being demolished. Making bricks and steel creates vast amounts of CO2, with cement alone causing 8% of global emissions. They say the construction industry should where possible re-use buildings, employ more recycled material, and use machinery powered by clean fuels. They are concerned about "embodied emissions", which is the CO2 emitted when buildings and materials are made.
