Carbon Dioxide Regulation refers to the methods and policies used to control the amount of carbon dioxide (CO2) released into the atmosphere. This is important because CO2 is a major greenhouse gas that contributes to climate change. Governments and organizations implement regulations to limit emissions from industries, vehicles, and other sources to help protect the environment. These regulations can include setting emission limits, promoting renewable energy sources, and encouraging energy efficiency. By reducing CO2 emissions, we can help mitigate global warming and its associated impacts, such as extreme weather events and rising sea levels.
