Global roll-out of successful policies may help limit global warming to well below 2 °C

Accelerating the global roll-out of good practices to reduce greenhouse gas emissions may help limit global warming to well below 2 °C. This is the main finding of the BRIDGE scenario, explored in the framework of COMMIT project, showing that it is possible to narrow the global emission gap between reductions announced as part of the Nationally Determined Contributions (NDCs) and reductions needed for a cost-optimal well below 2 °C scenario by 2030. After 2030, more comprehensive mitigation measures are needed – the study finds – if we are to keep well below 2 °C within reach. Although a wide set of good practice policies is included in the BRIDGE scenario, these are insufficient – even if all would be jointly implemented – to put the world on track to limit global warming to 1.5 °C.
