According to new research, the world must move beyond decreasing carbon dioxide emissions to decrease lesser-known pollutants like nitrous oxide, which play a major role in global warming.
CO2 emissions, which are the most abundant in the atmosphere, have dominated global climate discussions for decades. The shared objective of “net-zero” emissions usually refers only to CO2 emissions.
More than 100 countries have committed to a 30 percent reduction in methane emissions by 2030, a carbon-based greenhouse gas that traps heat significantly more effectively than CO2. The majority of those countries have yet to state how they intend to achieve the deadline.
