Detailed explanation-1: -The most effective way to reduce CO2 emissions is to reduce fossil fuel consumption. Many strategies for reducing CO2 emissions from energy are cross-cutting and apply to homes, businesses, industry, and transportation. EPA is taking common sense regulatory actions to reduce greenhouse gas emissions.

Detailed explanation-2: -Greenhouse gas emissions can be reduced by making power on-site with renewables and other climate-friendly energy resources. Examples include rooftop solar panels, solar water heating, small-scale wind generation, fuel cells powered by natural gas or renewable hydrogen, and geothermal energy.

Detailed explanation-3: -There are many ways to reduce greenhouse gas emissions from the industrial sector, including energy efficiency, fuel switching, combined heat and power, use of renewable energy, and the more efficient use and recycling of materials.

Detailed explanation-4: -Blending hydrogen (especially hydrogen produced from low-carbon sources) with natural gas in pipelines, as hydrogen burns more cleanly and reduces downstream air pollution and greenhouse gas emissions.
