A recent study (published 3 March) by Project Drawdown forms a comprehensive update to list of policy, business, community and individual actions needed to achieve ‘Drawdown’ – the point at which greenhouse gas (GHG) levels in the atmosphere peak and begin declining.

Drawdown’s first comprehensive analysis in 2017 was based around the Paris Agreement, listing refrigerant management, onshore wind and reducing food waste as the top three climate solutions. The updated version details the changes necessary to meet the IPCC’s call to climate action, made in its landmark report on global warming of 1.5C vs 2C above pre-industrial levels – an assertion that has seen the rise of net-zero national, state and business-level pledges accelerate rapidly across the world.

According to the updated report, it would be “feasible” to reach Drawdown by the early 2040s and global net-zero by 2050 without the use of any technologies and practices which do not currently exist – so long as simultaneous transitions towards stopping emissions at the source and sequestering them are made quickly.
