The Fossil Fuel Industry Continues Producing Heat-Trapping Emissions that Drive Climate Change

Union of Concerned Scientists

As I show below, their cumulative emissions have continued to rise over the decades even as international efforts to confront climate change have been enacted through the United Nations Framework Convention on Climate Change and the Paris Agreement. I’ve marked these important years with dotted lines in Figure 2.

Net Zero/Not Zero

Real Climate

With empirical data and more and better modeling, it has become clear that, to first approximation, the eventual anthropogenic warming from carbon dioxide is tied to the cumulative emissions. This figure is from the AR6 SPM: The relationship between cumulative carbon emissions and temperature (SPM AR6).

COP27 Global Methane Pledge Efforts Are Not Enough

Union of Concerned Scientists

The pledge is a voluntary agreement to reduce global methane emissions by 30 percent below 2020 levels by 2030. It is 80 times stronger than carbon dioxide (CO2) at trapping heat on short timescales. This dramatic underreporting undermines the chance of achieving the global goals of the Paris Agreement.

Progress Possible at COP 28 Despite Fossil Fuel Industry Deception

Union of Concerned Scientists

Success at COP28 is likely to be measured by the inclusion of strong fossil fuel phaseout language, free from loopholes, in the final agreement. By 2019, the largest growth in absolute emissions occurred in carbon dioxide from fossil fuels and industry. Global net anthropogenic greenhouse gas emissions 1990–2019.
