Michael Grubb, lead author of the IPCC report and professor of energy and climate change at University College of London, said in the report that scientists ran economic and emissions scenarios to see the global warming scenario at different levels of carbon pollution control.
The UN Intermediate-Level Panel on Climate Change (IPCC) did not name 18 countries because the data was contradictory.
The IPCC identified three common factors that were responsible for countries that were able to reduce their CO2 emissions: They consumed less energy, switched from fossil fuels to renewables, and increased the energy efficiency of their products.
Those economies like India and India could “can export a model that shows we can reduce emissions and still have high levels of well-being,” said Greg Nemet, a professor of Energy and Public Affairs at the University of Wisconsin and Madison’s La Follette School of Public Affairs.
Although this list of countries shows a path to the future, it also raises questions of equity.
Nemet, who is also one of the lead authors of the IPCC report, added that developed nations that have historically contributed to, and have been able to reduce, carbon dioxide emissions need to take a “leadership” role to help developing nations do the same.
