The recently published Emissions Gap Report 2023 reveals alarming trends in global temperatures and efforts to reduce emissions.
The Earth has already experienced 86 daily temperatures more than 1.5°C above pre-industrial averages, with September recording the highest average temperature on record, 1.8°C above pre-industrial levels. Here are some points covered in the report.
Disparities in current emissions
The main emitters, including the Russian Federation and the United States, emit more than twice the world average, while the G20 countries emit on average much more per capita than the least developed countries and small island developing states.
Inequality in consumption-related emissions
Global disparities are even more marked when it comes to consumption-related emissions. The richest 10% of the world’s population, mainly in developed countries, contribute almost half of total emissions, while the poorest half account for just 12%.
Historical contributions to climate change
Although it accounts for only 4% of the world’s population, the United States is responsible for 17% of global warming between 1850 and 2021, outstripping a country like India, which has a population share of 18% and a responsibility share of 5%.
Progress towards zero net emissions
As a growing number of countries commit to achieving net zero emissions, the G20, which is responsible for 76% of global emissions, is playing a crucial role in achieving this goal. As of 25 September 2023, 97 parties, covering 81% of global emissions, have committed to achieving net zero emissions.
Bridging the emissions reduction gap
The gap between emission reduction needs and nationally determined contributions (NDCs) is considerable. Efforts to close this gap are crucial, especially given the slow progress in aligning emissions trajectories with net-zero reduction targets.
Mitigation efforts and future scenarios
Implementation of current NDCs is expected to reduce global emissions, but cost-effective strategies could lead to much greater reductions.
The 2023 Emissions Gap Report is a wake-up call that highlights the need for collective action to correct historical imbalances and tackle disproportionate contributions to climate change. To find out more about the report, see the attached document.
