The Environmental Impact Assessment (EIA) serves as a mechanism to evaluate the environmental, social, and economic consequences of a project before any decisions are made. In recent years, however, governments, environmental specialists, researchers, media, and local communities have developed a comprehensive legislative and institutional framework for the EIA. To mitigate the environmental and social risks associated with any proposed project and its related components, as well as to safeguard and conserve the environment from negative effects, the Government of Bangladesh (GoB) has established specific regulations, policies, and guidelines. The EIA study has become a regulatory requirement for all RED categories and certain ORANGE categories of projects, contingent upon the directives issued by the Department of Environment (DoE), as specified in the Environment Conservation Rules. This study is essential for securing the Environmental Clearance Certificate, which is a prerequisite for any industrial and developmental initiatives. The Ministry of Environment, Forest and Climate Change (MoEF&CC), in accordance with Section 20 of the Environmental Conservation Act (ECA) 1995, has introduced the Environmental Conservation Rules 2023 (ECR 2023), thereby repealing the previous regulations enacted in 1997. According to Rule 5 (1) of ECR 2023, for the issuance of the Environmental Clearance Certificate (ECC), every industrial unit or project will be categorized into four classifications based on their site and environmental impact. This categorization is determined by the spatial extent of potential impacts on human health and both natural and manmade resources. The current review outlines the rules, fundamental principles, and procedures for EIA approval, while also highlighting the comprehensive guidelines for EIA approval in Bangladesh as per the new ECR 2023.

Serial No. | Year | Brief History |
|---|---|---|
1 | 1960s | EIA serves as an integral part of the environmental policy framework in the United States |
2 | 1969 | The National Environmental Policy Act (NEPA) of 1969 mandates that an environmental assessment be conducted for all significant federal projects and programs that may impact the quality of the human environment |
3 | 1972 | During the United Nations Conference on the Human Environment held in Stockholm, the UN General Assembly reached a consensus on a Declaration that encompasses 29 principles related to environmental issues and development |
4 | 1973 | Canada officially implements Environmental Impact Assessment (EIA) legislation via the federal Environmental Assessment and Review Process (EARP) |
5 | 1974 - 2006 | Between 1974 and 2006, various countries implemented Environmental Impact Assessment (EIA) legislation globally. Below is a list detailing the introduction of EIA legislation in these nations; Australia (1974), Germany and Thailand (1975), France (1976), Brazil (1977), Philippines (1978), Israel (1981), Costa Rica (1982), Pakistan (1983), Italy (1986), Netherlands (1987), Tunisia and Sri Lanka (1988), Belize and Estonia (1992), Bosnia and Herzegovina (1993), Nicaragua (1994), Romania and Bangladesh (1995), Montenegro and Nepal (1996), Japan (1997), Ecuador and Ireland (1998), Lebanon (2002), Panama (2006) |
6 | 1984 | The World Bank has implemented its "Environmental Policy and Procedures," which mandate the incorporation of environmental factors during the early phases of project definition and preparation |
7 | 1985 | The EIA Directive mandates that European Union Member States carry out Environmental Impact Assessments (EIAs) before granting approval for development projects that are expected to have considerable environmental impacts |
8 | 1987 | The United Nations Environment Programme (UNEP) has endorsed the Goals and Principles of Environmental Impact Assessment, which consist of 13 guidelines aimed at supporting the establishment and advancement of EIA systems in member nations, while also fostering the creation of a global EIA framework |
9 | 1989 | The EIA Operation Directive (OD) is intended for staff use and details the methods and procedures for implementing EIA in proposed projects, in addition to offering manuals tailored to specific sectors |
10 | 1992 | Principle 17 of the United Nations Rio Declaration highlights the significance of Environmental Impact Assessments (EIAs) as a "national instrument" applicable to all projects that may cause considerable negative environmental effects and are under the jurisdiction of national authorities |
11 | 2002 | UNEP highlighted the necessity for Environmental Impact Assessments (EIAs) to place greater focus on incorporating social and health effects |
12 | After 2010 | Day by day additional studies are carried out to supplement the EIA decision making process in all over the world |
