The emissions gap

This chapter presents an update of the emissions gap in 2030. In line with previous reports, the emissions gap is defined as the difference between where global greenhouse gas (GHG) emissions are heading under the current Nationally Determined Contributions (NDCs) and where science indicates emissions should be in 2030 to be on a least-cost path towards limiting warming to below 2°C or further to 1.5°C. The 2018 assessment draws on several new studies that present updated NDC estimates and additional low emission scenarios in line with achieving the climate objective of the Paris Agreement.
