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. 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.
Avoiding deforestation and improving land management could reduce emissions by the equivalent of about 9bn tonnes of carbon dioxide a year by 2030, according to the report, but contradictory subsidies, poor planning and vested interests could stop this from happening.
Key to any transition will be the growing social movements that are pressing for urgent action on climate breakdown. By driving behavioural change, such as moving away from the overconsumption of meat and putting pressure on governments and companies, civil movements have the power to drive the transformation needed in the next decade, say the report’s authors.
