The second little pig was unlucky. He built his house from sticks. It was blown away by a huffing, puffing wolf, which quickly ate him up. His brother, by contrast, built a wolf-proof house from bricks. The fairy tale could have been written by someone hired by the building industry, which strongly favours 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.

In 2015 world leaders meeting in Paris agreed to move towards zero net greenhouse-gas emissions in the second half of this century. That is a tall order, and the building industry makes it even taller. Cement- making(水泥制造) alone produces 6% of the world 's carbon emissions. Steel, half of which goes into buildings, accounts for another 8%. If you factor in all of the energy that goes into lighting, heating and cooling homes and offices, the world's buildings start to look like a giant environmental problem.

However, buildings can become greener. They can use more recycled steel and can be made in sections that can be put together later in off-site factories, greatly reducing lorry journeys. But no other building material has environmental credentials (证书) as exciting and overlooked as wood.

The energy required to produce a wooden beam 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. When a mature tree is cut down, a new one can be planted to replace it, capturing more carbon. After buildings are torn down, old beams and panels are easy to recycle into new structures. And for improving older buildings to be more energy efficient, wood is a good insulator(隔热材料). 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 equivalent.

Wood 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.
