Environmental Impact Assessment "is a systematic process to identify, predict and evaluate the environmental effects of proposed actions and projects." (UNEP EIA Training Resource Manual )
According to the Espoo Convention, EIA is "a national procedure for evaluating the likely impact of a proposed activity on the environment" (Article 1(vi)).
Transboundary EIA is the same as EIA, but there is an explicit consideration of potential transboundary effects, including consultation and public participation in the affected Party (i.e. the country that may be affected by a project in the 'Party of origin' or, more formally, the Contracting Party or Parties to the Convention likely to be affected by the transboundary impact of a proposed activity).
What does EIA do?
When done well, EIA has several potential benefits:
- It may help the project proponent to identify project alternatives (alternative locations or technology, for example) and mitigation and compensatory measures that reduce the environmental impact of the project. Suggestions may come from the public, the EIA experts, the consultees and the developer.
- It may provide for public involvement in the project design, promoting understanding between the community and developer. It may also promote good governance in the longer term: for example, Almer & Koontz found that public hearings as part of an EIA process "provide important indirect benefits that can contribute to the capacity for democratic governance and an active civil society".

General definition of Strategic Environmental Assessment: "The formalised, systematic and comprehensive process of evaluating the environmental impacts of a policy, plan or programme and its alternatives, including the preparation of a written report on the findings of that evaluation, and using the findings in publicly accountable decision-making." (Source: Therivel et al)
According to the Protocol on SEA, SEA is "the evaluation of the likely environmental, including health, effects, which comprises the determination of the scope of an environmental report and its preparation, and the carrying-out of public participation and consultations, the taking into account of the environmental report and the results of the public participation and consultations in a plan or programme." (article 2.6).

UNECE member States (see list) can become Parties to either instrument. For other UN Member States, the possibility of becoming a Party is described below.
For the Espoo Convention, an amendment to the Convention has been adopted (in 2001) to allow non-UNECE member States to become Parties to the Convention (see current status ). Once in the amendment is in force, the Meeting of the Parties to the Convention may approve the accession of a UN Member State that is not a member State of the UNECE.
The Protocol on SEA includes a similar provision. The 'Meeting of the Parties to the Protocol' may approve the accession of a UN Member State that is not a member State of the UNECE.
Accession (or ratification, etc.) to a treaty requires that a State is able to implement the treaty, i.e. all the preparatory work such as enactment of national legislation should have been completed.
The secretariat to the Espoo Convention undertook an informal review of transboundary EIA provisions in selected multilateral environmental agreements:
