Green infrastructure is more economical in the long term. Building low carbon infrastructure in the next five years will be four times less expensive for cities than building high carbon infrastructure that will need to be replaced in the future.
With 1.5 million people moving into cities and towns every week, the construction and refurbishment of urban infrastructure will account for one third of the remaining global carbon budget. That means cities have a crucial choice: build green infrastructure instead of traditional, and avoid locking in 45 Gt C02 by 2030, eight times the US’s current annual emissions.
