As this report shows, not only temperature records continue to be broken – global GHG emissions and atmospheric concentrations of carbon dioxide (CO2) also set new records in 2022.

New Delhi (ABC Live): The world is witnessing a disturbing acceleration in the number, speed and scale of broken climate records. At the time of writing, 86 days have been recorded with temperatures exceeding 1.5°C above pre-industrial levels this year. Not only was September the hottest month ever,it also exceeded the previous record by an unprecedented 0.5°C, with global average temperatures at 1.8°C above pre-industrial levels. These records were accompanied by devastating extreme events, which the Intergovernmental Panel on Climate Change (IPCC) has warned us are merely a meek beginning. While the records do not imply that the world has exceeded the 1.5°C temperature limit specified in the Paris Agreement, which refers to global warming levels based on multi-decadal averages, they signal that we are getting closer.

This fourteenth Emissions Gap Report is published ahead of the twenty-eighth session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP 28). It provides an annual, independent science-based assessment of the gap between the pledged greenhouse gas (GHG) emissions reductions and the reductions required to align with the long-term temperature goal of the Paris Agreement, as well as opportunities to bridge this gap. COP 28 marks the conclusion of the first global stocktake under the Paris Agreement, held every five years to assess the global response to the climate crisis and chart a better way forward. This closely mirrors the objective of the Emissions Gap Report, and the report aims to provide findings relevant to the concluding discussions under the global stocktake.

To inform COP 28 – including on the outcomes needed from the global stocktake – and set the scene for the next round of nationally determined contributions (NDCs) that countries are requested to submit in 2025, which will include emissions reduction targets for 2035, this report looks at what is required this decade and beyond 2030 to maintain the possibility of achieving the long-term temperature goal of the Paris Agreement. It underscores that maintaining this possibility hinges on relentlessly strengthening mitigation action this decade to narrow the emissions gap. This will facilitate significantly more ambitious targets for 2035 in the next round of NDCs, and pave the way for enhancing the credibility and feasibility of the net-zero pledges that by now cover around 80 percent of global emissions. Failure to bring global GHG emissions in 2030 below the levels implied by current NDCs will make it impossible to limit warming to 1.5°C with no or limited overshoot and strongly increase the challenge of limiting warming to 2°C.

As this report shows, not only temperature records continue to be broken – global GHG emissions and atmospheric concentrations of carbon dioxide (CO2) also set new records in 2022. Due to the failure to stringently reduce emissions in high-income and high-emitting countries (which bear the greatest responsibility for past emissions) and to limit emissions growth in low- and middle-income countries (which account for the majority of current emissions), unprecedented action is now needed by all countries. For high-income countries, this implies further accelerating domestic emissions reductions, committing to reaching net zero as soon as possible – and sooner than the global averages from the latest IPCC report implies – and at the same time providing financial and technical support to low- and middle-income countries. For low- and middle-income countries, it means that pressing development needs must be met alongside a transition away from fossil fuels.

Furthermore, the delay in stringent mitigation action will likely increase future dependence on carbon dioxide removal (CDR) from the atmosphere, but the availability of large-scale CDR options in the future cannot be taken for granted. This year, the report thus explores opportunities and challenges associated with energy transitions as well as the development and deployment of CDR.
