Emission reduction refers to the process of decreasing the amount of greenhouse gases and pollutants released into the atmosphere. This can be achieved through various methods, such as improving energy efficiency, using renewable energy sources like solar and wind, and adopting cleaner technologies in industries and transportation. The goal is to mitigate climate change and improve air quality. Governments, organizations, and individuals can all play a role in emission reduction. Policies like carbon pricing and incentives for electric vehicles encourage lower emissions. Additionally, practices such as recycling and sustainable agriculture contribute to a healthier environment by minimizing waste and resource consumption.
