This week on Dezeen, several key figures said that planting trees is not a reliable way of sequestering atmospheric carbon. 

Interviewed as part of our carbon revolution series, the experts cast doubts on the effectiveness of afforestation, as the trees planted need to grow for a long time to be effective as carbon stores.

"Planting trees is probably the most difficult potential method from a measurement and verification perspective," Paul Gambrill, CEO of carbon marketplace Nori told Dezeen.

Continuing the carbon revolution series, a report revealed that only one per cent of new buildings are being assessed to determine their carbon footprint.

However, one group that will be assessed are a series of low-carbon urban quarters that are set to be built as part of the Reinventing Cities global competition.
