Exponential roadmap: scaling 36 solutions to halve emissions by 2030

Greenhouse gas emissions could be halved in the next decade if a small number of current technologies and behavioural trends are ramped up and adopted more widely, researchers have found, saying strong civil society movements are needed to drive such change. Solar and wind power, now cheaper than fossil fuels in many regions, must be scaled up rapidly to replace coal-fired generation, and this alone could halve emissions from electricity generation by 2030, according to the Exponential Roadmap report from an international group of experts. If the rapid uptake of electric vehicles in some parts of the world could be sustained, the vehicles could make up 90% of the market by 2030, vastly reducing emissions from transport, it said.
