War on concrete continues

John Hardy quoted in “Flat-packed cities: wooden skyscrapers sprout over concrete concerns” by Thompson Reuters Foundation.

Vancouver plans a 40-storey building it says will be the world’s tallest, a title also claimed by Sumitomo Forestry’s 350-metre skyscraper in Tokyo.

“The interest is definitely being driven by environmental concerns – the amount of damage we’re doing with concrete is unbelievable,” said John Hardy, a sustainability expert in Bali, Indonesia.

“Bamboo and wood are carbon sequestering materials. So the other advantage of building with them is that you will look better to your children and grandchildren,” he said.

Construction of office towers, bridges, airports and highways is booming in developing nations across the world.

The manufacture of steel, concrete and brick accounts for about 16 per cent of global fossil-fuel consumption – and up to 30 per cent when transport and assembly of the materials is considered, according to the Yale School of Forestry & Environmental Studies.
