Emissions Gap Report 2023: UNEP

Emissions Gap Report 2023: UNEP

United Nations Environment Programme (UNEP) has released a report titled- the Emissions Gap Report 2023: Broken Record – Temperatures hit new highs, yet world fails to cut emissions (again), stating that urgent Climate Action is crucial to avoid the alarming trajectory of Temperature Rise.

  • The report is the 14th edition in a series that brings together many of the world’s top climate scientists to look at future trends in greenhouse gas emissions and provide potential solutions to the challenge of Global Warming.

Emissions Gap Report (EGR):

  • The EGR is UNEP’s spotlight report launched annually in advance of the Annual Climate negotiations.
  • The EGR tracks the gap between where global emissions are heading with current country commitments and where they ought to be to limit warming to 1.5°C.

Key Highlights of the Report:

  • Current pledges under the Paris Agreement set the world on a course for a 2.5-2.9°C temperature rise above pre-industrial levels by the end of this century.
  • Paris Agreement (also known as the Conference of Parties 21 or COP 21) is a landmark environmental accord that was adopted in 2015 to address climate change and its negative impacts.
  • To limit warming to 1.5-2°C, substantial emission cuts of 28-42% by 2030 are necessary.
  • Greenhouse Gas Emissions (GHG) hit a new record of 57.4 Gigatonnes of Carbon Dioxide Equivalent (GtCO2e) in 2022, with a 1.2% increase from the previous year.
  • Fossil CO2 emissions account for approximately two thirds of current GHG emissions using 100-year global warming potentials.
  • Fossil CO2 emissions grew between 0.8–1.5% in 2022 and were the main contributor to the overall increase in GHG emissions.
  • In 2022, fluorinated gases emissions grew by 5.5%, followed by Methane at 1.8% and nitrous oxide (N2O) at 0.9%.
    GHG emissions across the G20 also increased by 1.2% in 2022. However, members vary widely in their trends with increases
  • in China, India, Indonesia and the United States of America, but decreases in Brazil, the European Union and the Russian Federation. Collectively, the G20 currently accounts for 76% of global emissions.23
  • In 2022, energy supply was the largest source of emissions at 20.9 GtCO2e (36% of the total), followed by Industry (25%), followed by agriculture and LULUCF CO2 (18%), transport (14%) and buildings ( 6.7%).
  • If current policies and pledges continue, global warming will likely reach 3°C above pre-industrial levels by the end of the century.
  • Implementing unconditional Nationally Determined Contributions (NDCs) could limit the rise to 2.9°C, while conditional NDCs might cap it at 2.5°C.
  • Although countries have made Net-Zero Pledges, none of the G20 Countries are reducing emissions at a pace consistent with their targets.
  • Even in the most optimistic scenario, the likelihood of limiting warming to 1.5°C is only 14%.
