One other Emissions Hole Report from the United Nations Setting Programme (UNEP) printed final week, 24 de October.
This time titled “Emissions Gap Report 2024: No more hot air … please!”, in regards to the “massive gap between countries rhetoric and reality”.
As local weather impacts intensify globally, nations should ship a couple of months away stronger ambition and motion within the subsequent spherical of Nationally Decided Contributions (NDCs).
Perhaps one of many key functions of this 2024 version of the report is “naming and shaming” (i.e. publicly indicating) nations extra and fewer more likely to obtain their NDCs. And in addition pointing the finger on the G20 nations.
In keeping with the chief abstract, “GHG emissions across the G20 members also increased in 2023 and accounted for 77 per cent of global emissions. If all African Union countries are added to the G20 total, more than doubling the number of countries from 44 to 99, total emissions increase by just 5 percentage points to 82 per cent. The six largest GHG emitters accounted for 63 per cent of global GHG emissions. By contrast, least developed countries accounted for only 3 per cent.”
The report alerts that international greenhouse fuel emissions in 2023 had been 1.3 per cent larger than 2022 ranges, setting a brand new file of 57.1 GtCO2e (ton of carbon dioxide equal), of which:
-
26% or 15.1 GtCO2e from the ability sector (i.e. electrical energy manufacturing);
-
15% or 8.4 GtCO2e transport;
-
11% or 6.5 GtCO2e business;
-
11% or 6.5 GtCO2e agriculture;
-
10% gas manufacturing (i.e. oil, fuel, strong fuels);
-
9% industrial processes to provide cement, chemical compounds and metals;
-
7% land-use change and forestry (LULUCF);
-
6% buildings; and
-
4% strong and liquid waste.
“The magnitude of the challenge is indisputable. At the same time, there are abundant opportunities for accelerating mitigation action … Technology developments, particularly in wind and solar energy, continue to exceed expectations … The updated assessment of sectoral emission reduction potentials included in this year’s report shows that the techno-economic emission reduction potential based on existing technologies and at costs below US$200 per tCO2e remains sufficient to bridge the emissions gap in 2030 and 2035. But this will require overcoming formidable policy, governance, institutional and technical barriers as well as an unprecedented increase in the support provided to developing countries along with a redesigning of the international financial architecture.”
At this US$200/tCO2e price degree, the report signifies 41 GtCO2e (adjusted by some overlaps) because the annual mitigation potential by 2035, divided as follows by sector:
-
14.7 GtCO2e in Vitality;
-
12.8 GtCO2e in Agriculture, Forestry, and Different Land Use (AFOLU);
-
6.6 GtCO2e in Trade;
-
4.8 GtCO2e in Transport;
-
4.2 GtCO2e in Buildings; and
-
2.4 GtCO2e different.
With AFOLU within the 2nd place when it comes to potential, would that imply that nature associated options are seen by the physique of scientists behind this report as extra urgently related than technological mitigation itself, by sectors reminiscent of business and transportation, for instance? It seems so.
The report is the fifteenth version in a collection that brings collectively most of the world’s prime local weather scientists to take a look at future tendencies in greenhouse fuel emissions and supply potential options to the problem of world warming.
