Excuse me: what is EIA? Does every new enterprise need to do environmental assessment? Which government departments are EIA mainly used for?

EIA is environmental impact assessment. Generally speaking, before a new project is started, an environmental impact assessment must be carried out. The environmental impact assessment report can entrust experts to investigate the natural environment, social environment and atmospheric environment quality status of the proposed project, and analyze the possible impact of environmental factors such as project scale, production technology level, product scheme, consumption of raw materials, fuel and water, and pollutant discharge. Report on feasible improvement measures and strengthening environmental protection measures for the surrounding soil and crops, people's health, geology, hydrology, meteorology, etc., and send it to the environmental protection department for approval before the project can be established.
