Carbon emission reduction refers to the process of decreasing the amount of carbon dioxide (CO2) and other greenhouse gases released into the atmosphere. This is crucial for combating climate change, as these emissions trap heat and contribute to global warming. 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 carbon emission reduction. Policies such as carbon pricing and incentives for clean energy can encourage lower emissions. Additionally, practices like reforestation and carbon capture technology help absorb or prevent the release of CO2, further supporting environmental sustainability.
