  1. Global GHG emissions set new record of 57.4 GtCO2e in 2022
  2. Current and historical emissions are highly unequally distributed within and among countries, reflecting global patterns of inequality
  3. There has been negligible movement on NDCs since COP 27, but some progress in NDCs and policies since the Paris Agreement was adopted
  4. The number of net-zero pledges continues to increase, but confidence in their implementation remains low
  5. The emissions gap in 2030 remains high: current unconditional NDCs imply a 14 GtCO2e gap for a 2°C goal and a 22 GtCO2e gap for the 1.5°C goal. The additional implementation of the conditional NDCs reduces these estimates by 3 GtCO2e
  6. Action in this decade will determine the ambition required in the next round of NDCs for 2035, and the feasibility of achieving the long-term temperature goal of the Paris Agreement
  7. If current policies are continued, global warming is estimated to be limited to 3°C. Delivering on all unconditional and conditional pledges by 2030 lowers this estimate to 2.5°C, with the additional fulfilment of all net-zero pledges bringing it to 2°C
  8. The failure to stringently reduce emissions in high-income countries and to prevent further emissions growth in low- and middle-income countries implies that all countries must urgently accelerate economy-wide, low-carbon transformations to achieve the long-term temperature goal of the Paris Agreement
  9. Low- and middle-income countries face substantial economic and institutional challenges in low-carbon energy transitions, but can also exploit opportunities
  10. Further delay of stringent global GHG emissions reductions will increase future reliance on CDR to meet the long-term temperature goal of the Paris Agreement
