Zambia’s new Environmental Impact Assessment Regulations: What You Need to Know

If you are a developer, investor, or business owner planning a project in Zambia, there is a new set of rules you need to fully understand. On 9 January 2026, the Environmental Management (Environmental Impact Assessment) Regulations, 2026 (Statutory Instrument No. 3 of 2026) came into force, revoking the old Environmental Protection and Pollution Control (Environmental Impact Assessment) Regulations, 1997, which had been on the books for nearly three decades.

What has actually changed, and why does it matter?

A fresh legal home

The old regulations were made under the Environmental Protection and Pollution Control Act of 1990. The new ones sit under the Environmental Management Act, 2011, which has been Zambia’s governing environmental statute for some time. This shift brings the Environmental Impact Assessment (EIA) framework into proper alignment with the current law, something practitioners had long flagged as overdue.

A more structured classification system

Perhaps the most significant practical change is the introduction of a tiered project classification system. Rather than a broad, relatively undifferentiated list, projects are now sorted into five classes (Class I through Class V), based on scale, environmental sensitivity, and sector. 

Class I covers the most significant projects (large-scale mining, major dams, nuclear power plants, industrial estates over 500 hectares). Class V sits at the lighter end, ie small-scale quarrying, fuel service stations, and solar projects below 20MW. Classes I to IV require a full Environmental and Social Impact Statement (ESIS), while Class V projects need only an Environmental and Social Project Brief (ESPB), a less onerous document.

Under the 1997 rules, the distinction was essentially binary, project brief or full environmental impact statement, with less nuanced guidance on which projects fell where. The new tiered approach gives developers much clearer expectations from the outset.

Tighter timelines

The new regulations also introduce more defined timelines at each stage of the regulatory process. The Zambia Environmental Management Agency (ZEMA) now has five days to assess whether submitted terms of reference are acceptable, seven days to transmit a completed environmental and social impact statement (ESIS) to appropriate authorities, and must make its final decision within 35 days (or 45 days where a public hearing is required). Under the old framework, the Council had 30 to 40 days to act on a project brief, but the intermediate steps were far less structured. For developers, greater procedural certainty is a welcome improvement.

Decision letters have a shelf life

This is a point that often catches clients off guard. A decision letter, the green light from ZEMA approving your project, lapses if land preparation and construction have not started within three years of approval. The 1997 regulations had a similar rule, but the new framework is more detailed about what happens next: developers can apply for an extension before expiry, and ZEMA will determine whether a fresh EIA is needed, a supplement is sufficient, or the project can simply proceed.

Decision letters can be transferred

A genuinely new feature is the formal mechanism for transferring a decision letter to another entity, for instance, where a project changes hands. The transferee and transferor share liability for obligations under the letter up to the date of transfer, after which the transferor is released from future obligations. This will be of particular interest in mergers, acquisitions, and restructures involving projects with existing environmental approvals.

Stronger penalties

The penalty regime has been significantly upgraded. Contraventions now attract fines of up to 300,000 penalty units (ZMW 0.40 per penalty unit) or imprisonment of up to three years, or both. The old regulations capped fines at 556 penalty units, a figure that had long since lost any deterrent effect. ZEMA also retains the power to cancel or suspend a decision letter as an additional sanction.

What should developers do now?

If you have a project in the pipeline, the first step is to identify which class it falls into under the new schedules, that determines your process and your fees. 

If you already hold a decision letter, check whether your three-year clock is still running. And if you are in the middle of an application that was lodged under the old regulations, the transitional provisions confirm that those applications carry over and will be processed under the new framework.

The 2026 Regulations represent a meaningful modernisation of Zambia's environmental approval regime. Navigating them well from the start can save significant time and cost down the line.
