China builds vertical forests to CO2 emissions



May 12, 2017

China is building vertical forests, each planted with 1,100 trees and 2,500 plants to help mitigate its CO2 emissions. The towers, to be completed by the end of 2018, will each absorb around 25 tons of CO2 every year. But isn’t this more a feel-good than effective solution to a huge problem?

It’s also hoped that the towers will also help to mitigate some of China’s terrible smog.

However, as China’s emissions are around 10 giga tonnes of CO2 per year, one commenter has calculated that China would need to build 4 million of these towers to absorb just 1% of its emissions.

While the towers will look great and who doesn’t want more trees – wherever they’re planted – wouldn’t be a lot better for China to just wean itself off coal-fired power?
