Environmental Impact Assessment (EIA) is a process used to identify and assess the potential environmental impacts of proposed projects or activities. The classification of EIA projects can vary depending on the specific criteria and regulations of each country or region. However, I can provide you with a general classification of different types of EIA projects based on their nature and sector. Please note that this classification is not exhaustive and can vary in different contexts.

It is important to note that the classification of EIA projects may also consider the scale and magnitude of the proposed activities, their potential impacts on sensitive ecosystems or protected areas, and the involvement of public participation in the decision-making process. Additionally, specific regulations and guidelines for conducting EIAs may vary across jurisdictions, so it’s essential to consult the relevant local authorities and regulations for accurate classifications and requirements.
