Energy conservation and emission reduction means saving energy, reducing energy consumption and reducing pollutant emissions. Energy conservation and emission reduction include two major technical fields, energy conservation and emission reduction. The two are related and different. Emission reduction projects must strengthen the application of energy-saving technologies to avoid the surge in energy consumption caused by one-sided pursuit of emission reduction results, and focus on the balance between social and environmental benefits. "Energy Conservation Law of the People's Republic of China" refers to energy conservation (referred to as energy conservation), which refers to strengthening the management of energy use, taking technically feasible, economically reasonable and environmentally and socially acceptable measures, from energy production to consumption. Reduce consumption, reduce losses and pollutant emissions, stop waste, and use energy efficiently and reasonably. my country's fast-growing energy consumption and high foreign dependence on oil prompted the government to put forward in early 2006 that it hoped that by 2010, the energy consumption per unit of GDP will be reduced by 20% compared with 2005, and the emission of major pollutants will be reduced by 10%. The combination of these two indicators is what we call "energy saving and emission reduction".
