The median estimate of global greenhouse gas emissions in 2030 under current policies is 57 billion metric tons of carbon dioxide equivalent (GtCO₂e). This results in an emissions gap of 16 GtCO₂e consistent with limiting global warming to below two degrees Celsius. If the unconditional nationally determined contributions (NDCs) are fully implemented, the emissions gap for a below two degrees Celsius scenario would be reduced to 14 GtCO₂e. The full implementation of conditional NDCs would reduce the emissions gap by a further three GtCO₂e.
