Environmental Impact Assessments

US National Environmental Policy Act

• Signed by Nixon in 1970

• First legislation anywhere to require systematic evaluation of environmental effects before federal decisions

• Established the concept of the Environmental Impact Statement (EIS)

The Idea of Environmental Impact Assessments

Environmental consequences should be anticipated before a project proceeds, not dealt with after the damage is done.

EIA Essentials

• It should allow the public and other stakeholders to present their views and inputs on the planned development

• It must contribute to and improve the project design, so that environmental as well as socioeconomic measures are core parts of it

• It is critical that that the approved practices and design are followed during the project operations and construction and that ongoing monitoring is in place during the lifetime of the project

First Wave of Adoption of EIA

• Rich countries (Australia, Canada, New Zealand & France)

• Developing countries (Colombia & Philippines)

UN & EIA

• 1987: UNEP adopts Goals and Principles of EIA

• 1991: Espoo Convention on transboundary EIA

• 1992 Rio Declaration Principle 17 explicitly calls for EIA as a national instrument

World Bank & EIA

• In 1989, the World Bank adopted EIA for major development projects

• Borrowing countries must comply with Bank safeguards

• Spread EIA requirements to many countries that didn't have them

Global Diffusion of EIA

• Other MDBs (ADB, AfDB, IDB, EBRD) followed similar paths to the WB

• Today: >100 countries have EIA legislation

• Near-universal requirement for large development projects worldwide

The 7 Steps of EIAs

1. Screening: Does this project need an EIA?

2. Scoping: What should the EIA cover?

3. Impact assessment: What are the likely environmental and social effects?

4. Impact management: How to avoid, minimize, restore, compensate? (mitigation hierarchy)

5. EIA report: Compile findings into a document.

6. Review and licensing: Authority decides: approve/approve with conditions/reject.

7. Monitoring: Track whether mitigation measures actually work.

1. Screening

Determines whether the environmental and social impacts of a proposed development project would be significant enough to develop an EIA.

2. Scoping

Establish the boundaries of the EIA, set the basis of the analyses that will be conducted at each stage, describe the project alternatives and consult the affected public.

3. Impact Assessment & Mitigation

Evaluate the socioeconomic and environmental impacts of the planned project and its alternatives, and then identify the mitigation measures to reduce those impacts.

4. Impact Management

Prepare the plans required for addressing mitigation measures and other project risks, such as technological failures and natural disasters.

5. The EIA Report

Pull together all the research and work done during the previous steps into a comprehensive, structured document, ensuring that the EIA report contains all the key components.

6. Review & Licensing

Designated authorities review the EIA report to determine if the planned project will get a license or if it requires amendments.

7. Monitoring

Ensure that the mitigation measures, priorities listed in the EMP, and contingency plans are properly implemented and effectively address the project’s impacts.

Environmental & Social Standards (ESS)

• ESS1 Assessment and Management of Environmental and Social Risks and Impacts

• ESS2 Labor and Working Conditions

• ESS3 Resource Efficiency and Pollution Prevention and Management

• ESS4: Community Health and Safety

• ESS5: Land Acquisition, Restrictions on Land Use and Involuntary Resettlement

• ESS6: Biodiversity Conservation and Sustainable Management of Living Natural Resources

• ESS7: Indigenous Peoples/Sub-Saharan African Historically Underserved Traditional Local Communities

• ESS8: Cultural Heritage

• ESS9: Financial Intermediaries

• ESS10: Stakeholder Engagement and Information Disclosure

Effectiveness of EIA

• Highly uneven

• Many countries have EIA legislation on paper, but implementation is weak:

  • Limited institutional capacity

  • Underfunded environmental agencies

  • Consultant-driven reports that tell the client what they want to hear

Other Limitations of EIA

• Communication failures: EIA reports are technical, voluminous, and often inaccessible to the communities most affected

• Monitoring gap: Even when EIAs are well done, monitoring and enforcement during project implementation is often weak

• The EIA is a one-time exercise but projects often last decades

Politics & EIA

• EIA assumes a rational-technocratic model: good information leads to good decisions

• But decisions about large projects are political

• In many contexts, the decision to approve precedes the assessment, and the EIA becomes a post-hoc justification

Shift from Consultation to Consent

• Shift toward Free, Prior and Informed Consent (FPIC) for Indigenous peoples embedded in the World Bank ESF (ESS7, 2016) and IFC Performance Standards

• But ESS7 does not grant veto rights for local people

Courts & Civil Society

• In some countries (e.g., India, Kenya, South Africa, Colombia), courts used to challenge inadequate EIAs

• In LatAm, Escazú Agreement (2018) now guarantees access to environmental information, public participation in environmental decision-making, and access to justice

  • Communities now have a legal basis to demand EIA documents, participate in EIA processes, challenge inadequate assessments in court

Transparency & Open Data

• EIA documents from major development banks are now publicly available online (e.g. Canada's Impact Assessment Registry, World Bank ESRS repository)

• Satellite monitoring (Global Forest Watch) and open environmental data → evidence base that communities and NGOs can use to challenge project claims
