To limit global warming to 1.5 or 2 degrees Celsius, we need to reduce all greenhouse gases, not just CO2. Scientists used a model to study different ways to cut CO2 and non-CO2 emissions. They found that if we don't cut non-CO2 emissions enough, we'll need to reach net-zero CO2 emissions 20 years earlier. But if we tackle all greenhouse gases together, we can reach the 1.5-degree goal. Switching to cleaner fuels helps reduce non-CO2 emissions, while targeted actions can cut emissions from industrial processes and cooling. Overall, cutting all greenhouse gases can help us reach our climate goals sooner.
