The energy sector is the contribution of 37% of worldwide Greenhouse gas emissions. Emission of GHG is increased due to fossil fuel-based resources, lack of efficiency, and lack of knowledge. Improving energy efficiency in the industry through Energy management contributes to reducing GHG emissions and reducing energy waste. Different methods can reduce energy management and GHG emissions, and they should be implemented in the building, industrial, and transportation sectors. Energy management techniques and the contribution of it to GHG mitigation are described in this article.
