What is the scale and challenge of the energy system transition required to meet long-term climate goals? Policy Card C2a

Achieving emissions consistent with a 50% chance of remaining below 2°C by 2100 will require large changes in the energy system over the 21st century, including increased use of renewables and significant retirement of fossil fuel generation capacity. Delaying global coordinated mitigation action towards the 2°C goal beyond 2020 would substantially increase the costs of mitigation and require very rapid subsequent rates of decarbonisation.
