ESIA or environmental audit? Matching the tool to your project
An ESIA assesses a proposed project before it starts; an environmental audit checks how an operating project performs. How to tell which one you need in Uganda.
"Do we need an ESIA or an environmental audit?" is one of the questions we hear most often from developers, factory managers and project financiers. The two are related, and both are submitted to the National Environment Management Authority (NEMA), but they answer different questions at different points in a project's life.
In short, an Environmental and Social Impact Assessment (ESIA) looks forward: it predicts the effects of a project that has not yet been built and sets out how to manage them. An environmental audit looks at what is actually happening: it checks whether an operating project is complying with the law, its approval conditions and its own management plan. This guide explains both, how they connect, and how to work out which one your project needs.
The two tools side by side
| Aspect | ESIA | Environmental compliance audit |
|---|---|---|
| Question it answers | What effects will this project have, and how should they be managed? | Is this project complying with its obligations, and where is it falling short? |
| When | Before the project starts, and before significant expansions or changes | While the project is being built or operated; usually every year |
| Main legal basis | National Environment Act Cap. 181 and the National Environment (Environmental and Social Assessment) Regulations, 2020 | National Environment Act Cap. 181 and the National Environment (Audit) Regulations, S.I. No. 47 of 2020 |
| Evidence used | Baseline surveys, predictions, consultation with affected people | Records, permits, site inspection, monitoring results, consultation |
| Key output | ESIA report and Environmental and Social Management Plan (ESMP) | Audit report with a compliance assessment and a corrective action plan |
| NEMA outcome | Decision on approval, usually a certificate with conditions | Decision on the audit: commendation, further investigation, a compliance agreement, notices or orders |
The ESIA: deciding before you build
Under the National Environment Act Cap. 181, projects of the types listed in the Act's schedules must be assessed, and approved by NEMA, before they are implemented. The detailed procedure is set out in the National Environment (Environmental and Social Assessment) Regulations, 2020. The purpose is to make sure environmental and social risks are understood and planned for while there is still time to change the design, location or method of the project.
A typical ESIA moves through these stages:
- Screening. The developer submits a project brief describing the project, its location and its likely effects. This determines whether a full assessment is needed.
- Scoping and terms of reference. The study is focused on the issues that matter for this project and site.
- Baseline studies. Field surveys and measurements establish existing conditions: water, air, noise, soils, ecology, land use and the social and economic setting.
- Stakeholder consultation. Affected communities, local governments and lead agencies are consulted, and their concerns are recorded and addressed.
- Impact assessment. Positive and negative effects are predicted and their significance evaluated.
- Mitigation and the ESMP. Measures to avoid, reduce or compensate for adverse effects are set out, with responsibilities, monitoring and costs.
- Submission, review and decision. NEMA reviews the report, consulting lead agencies where needed, and decides whether to approve the project and on what conditions.
Where a project is financed by a development bank or international lender, the ESIA is usually also prepared to meet that lender's standards, such as the World Bank Environmental and Social Framework, the IFC Performance Standards or the AfDB Integrated Safeguards System.
The ESIA is not the end of the process. Its ESMP and the conditions on NEMA's certificate of approval become the commitments the project will be held to for the rest of its life.
The environmental audit: checking what is happening
The National Environment (Audit) Regulations, S.I. No. 47 of 2020, define an environmental audit as a systematic, documented and periodic evaluation of how well a project, its management system, facilities and equipment perform in protecting the environment and conforming to the law. These regulations replaced the 2006 Audit Regulations, which should no longer be cited as current.
The regulations describe three kinds of audit:
- Compliance audits are carried out by the developer, through a certified audit team, to establish the project's compliance status. They are mandatory for the projects listed in Schedule 3 of the regulations.
- Enforcement audits are carried out by NEMA or a lead agency to enforce compliance, for example after a complaint or petition.
- Voluntary audits are commissioned by an organisation for its own purposes, such as preparing for certification, investment or a sale.
Who must carry out a compliance audit, and how often
Developers of projects listed in Schedule 3 of the Audit Regulations must carry out a compliance audit every year, unless NEMA directs otherwise. Schedule 3 covers a wide range of activities, including fuel service stations, factories and processing plants, mining and quarrying, waste facilities, large water abstractions, hotels and lodges in or near sensitive areas, and energy projects. NEMA can also require an audit of a project that is not on the list, and many certificates of approval include an audit condition of their own. Check your certificate as well as the schedule.
What the audit examines
A compliance audit measures the project against:
- the conditions of the ESIA certificate of approval;
- the commitments in the ESMP;
- the National Environment Act Cap. 181 and the regulations and standards made under it, for example on waste, effluent, air quality and noise;
- the conditions of other permits and licences, such as water abstraction and wastewater discharge permits;
- other applicable law, such as the Occupational Safety and Health Act Cap. 231 and the Water Act Cap. 164;
- issues raised in previous audits, monitoring reports and inspections, and whether they have been closed.
The audit also assesses how effective the project's environmental management system is, and it must include consultation with people who are, or are likely to be, affected by the project.
Who carries it out, and what is submitted
The audit is carried out by a team of environmental auditors certified and registered under the National Environment (Conduct and Certification of Environmental Practitioners) Regulations, supervised by a lead environmental auditor. Specialists can be added where the project needs expertise the team does not have.
The report follows the content set out in Schedule 2 of the Audit Regulations, and every team member signs a declaration. Where the audit finds non-compliance, the report must include a corrective action plan that sets out:
- the proposed actions and specific deliverables;
- who is responsible for each action;
- an implementation schedule with timeframes;
- a commitment to improve the environmental management system, or other measures, so the problem does not recur.
The developer submits two hard copies and an electronic copy to NEMA and pays the fee set by the regulations. NEMA may ask a lead agency to comment, and must communicate its decision within 90 days of receiving the report.
Why accuracy matters
The developer is legally responsible for the content of the audit report. Making a false or misleading statement in a compliance audit report, failing to submit one, or failing to implement a corrective action plan are offences under the regulations. The maximum penalty is 10,000 currency points (UGX 200 million), up to five years' imprisonment, or both, for an individual, and 50,000 currency points (UGX 1 billion) for a company. A credible audit identifies problems honestly and shows a realistic plan to fix them.
How the two connect
An ESIA and the audits that follow it are parts of one cycle:
- The ESMP written during the ESIA becomes one of the main yardsticks later audits measure against. A realistic, specific ESMP makes every future audit easier; a generic one creates commitments the project cannot show it has met.
- The baseline data collected for the ESIA gives auditors a reference point for detecting change in water quality, air quality, noise and other conditions.
- The certificate conditions issued after the ESIA are audited item by item.
- Every third year, the Audit Regulations require an updated environmental and social management and monitoring plan to be submitted with the audit report, so the plan keeps pace with how the project has actually developed.
Which do you need? Common situations
| Your situation | What you are likely to need |
|---|---|
| You are planning a new project of a type listed in the National Environment Act Cap. 181 | A project brief for screening and, where required, a full ESIA, with NEMA approval before work begins |
| Your project is operating with a NEMA certificate of approval | Annual compliance audits if it is a Schedule 3 project or your certificate requires them, plus the monitoring your ESMP commits to |
| You plan to expand, change processes or change the use of a site | Early advice on whether the change needs screening and a new or updated assessment; your audit will also need to reflect the change |
| Your facility is operating but has no approval, or its approval does not cover what it now does | Specialist advice and early engagement with NEMA on how to bring the facility into compliance; NEMA can direct an audit of any project |
| A complaint or petition has been made about your operations | Be prepared for an enforcement audit by NEMA or a lead agency, which can lead to an instruction to carry out a compliance audit |
| You are seeking finance, preparing for ISO 14001 certification, or buying or selling a facility | A voluntary audit or due-diligence review, often against lender standards such as the IFC Performance Standards |
Mistakes we see often
- Treating the certificate as the finish line. Approval brings ongoing obligations: monitoring, record-keeping, reporting and audits.
- Copying a generic ESMP. Commitments that are not tailored to the project become non-compliances at the first audit.
- Not keeping records. Without monitoring results, waste records, training logs and grievance records, an auditor cannot verify compliance, even where good practice is happening.
- Letting audits lapse. Failing to submit an audit report is itself an offence, and gaps make it harder to show a consistent compliance record.
- Citing outdated law. Reports should cite the 2020 Audit Regulations, not the 2006 version, and should cite Acts in their 7th Revised Edition form.
Questions to ask early
- Has the project started, or is it still being planned?
- Is it a type of project listed in the National Environment Act Cap. 181, or in Schedule 3 of the Audit Regulations?
- Does it have a NEMA certificate of approval, and what conditions does that certificate set?
- Is a lender involved whose safeguard standards also apply?
- When was the last audit, and are its corrective actions closed?
- Are expansions or changes planned in the next year?
