    The second little pig was unlucky. He built his house from sticks, which was blown away by a wolf. His brother, by contrast, built a wolf-proof house from bricks. The fairy tale could have been written by an agent for the construction industry, strongly favoring brick, concrete and steel. However, in the real world it would help reduce pollution and slow global warming if more builders copied the wood-loving second pig.

No other building material has environmental credentials (认证信息) as exciting and overlooked as wood. The energy required to produce a laminated wooden beam (层压木梁) is one-sixth of that required for a steel one of comparable strength. As trees take carbon out of the atmosphere when growing, wooden buildings contribute to negative emissions by storing the stuff. And for refitting older buildings to be more energy efficient, wood is a good insulator (绝缘体). A softwood window frame provides nearly 400 times as much insulation as a plain steel one of the same thickness and over a thousand times as much as an aluminium (铝) equivalent.

But such bigger stories are still uncommon. Governments can help push the industry to use more wood, particularly in the public sector — the construction industry’s biggest client. That would help wood-building specialists achieve greater scale and lower costs. Zero-carbon building regulations should be altered to take account of the emissions that are presented in materials.

Construction codes could be regulated to make building with wood easier. Here the direction of travel is wrong. Britain, for instance, is banning the use of timber on the outside of tall buildings after 72 people died in a tower fire in London in 2017. That is a nonsense. Grenfell Tower was covered in aluminium and plastic, not wood. Modern cross-laminated timber (交叉层叠木板) panels perform better in fire tests than steel ones do.

Carpentry alone will not bring the environmental cost of the world’s buildings into line. But using wood can do much more than is appreciated. The second little pig was not wrong, just before his time.
