Greenhouse gas reduction refers to efforts aimed at decreasing the emissions of gases that trap heat in the atmosphere, such as carbon dioxide and methane. These gases contribute to global warming and climate change, which can lead to severe environmental impacts. Strategies for reduction include using renewable energy sources like solar and wind, improving energy efficiency, and promoting sustainable transportation options. Governments, businesses, and individuals can all play a role in greenhouse gas reduction. Policies such as carbon pricing and regulations on emissions encourage industries to adopt cleaner technologies. Additionally, practices like reforestation and reducing waste can help absorb carbon dioxide, further contributing to a healthier planet.
