Panama's Ministry of Environment (Ministerio de Ambiente, MiAmbiente) has issued new regulations for the environmental impact assessment process (evaluación de impacto ambiental), the review a project must pass before its works can go ahead. They take the form of Executive Decree 4 of May 28, 2026, published in Official Gazette 30534-B. An executive decree is a regulation issued by the President with the relevant minister to implement a statute, and it applies alongside the laws it develops.
The decree repeals in one stroke the two decrees that governed the subject until now, Executive Decree 1 of 2023 and Executive Decree 2 of 2024, and it took effect on promulgation. This is not a touch-up. It reorganises the whole procedure, from the initial study to sanctions, and the points below are the ones a developer or investor should keep in view.
Three categories set the depth of the study
The decree classifies each environmental impact study into one of three categories according to the expected impact. The category determines how deep the study must go, the applicable time limits and the minimum content required, so the table is the first thing to read when scoping a project.
| Category | Expected impact | What it implies |
|---|---|---|
| Category I | Low or minor | The lightest level of study |
| Category II | Medium or moderate, mitigable with known measures | An intermediate study |
| Category III | High or severe, synergistic or cumulative | An exhaustive analysis |
Picking the right category from the outset is a planning decision, not a formality, because it drives both the cost and the timetable of the approval.
Splitting a project is now expressly banned
This is probably the change with the greatest practical weight. Breaking a development into pieces so that each one looks low-impact, and so avoids a comprehensive assessment, is now expressly prohibited.
For investors buying into a master-planned development, this also becomes a due diligence point: ask whether the environmental approvals cover the full project or only a slice of it.
Financial guarantees and accountable consultants
The Ministry may require the project promoter to post an environmental financial guarantee backing its environmental obligations. The requirement depends on the study category, the nature of the project and the risks of its construction, operation and closure phases. In practice, an environmental commitment stops being just a signature and gains financial backing.
The people who prepare the studies are also brought into the frame. Consultants must be listed in a registry of environmental consultants, subject to regulation, administrative sanctions and even disqualification, so the quality and responsibility of the consultant now formally count.
Public participation under the Escazú Agreement
The decree relies expressly on the Escazú Agreement, the Latin American and Caribbean treaty on access to environmental information, public participation and justice, which Panama approved by Law 125 of 2020. It adds concrete mechanisms, a community consultation and a public forum during the review, so that any person can learn about the study and submit observations. Developers should build that step into their timeline rather than treat it as an afterthought.
Emergencies and the digital platform
The decree includes an exception for emergencies. Actions carried out during an officially declared state of emergency, such as earthquakes, floods, tsunamis, hurricanes or health emergencies, and for up to sixty days afterwards, do not need to go through the assessment when they are tied to mitigating the disaster. It is a reasonable safety valve for acting fast when it matters.
The whole procedure now runs on a digital platform operated by the Ministry. Filing, review and follow-up all go through it, with its own rules on receipt and notification.
What developers should do now
Any project with a land component, whether a residential development, an industrial plant, an infrastructure work or a tourism project, has to clear environmental review alongside zoning and municipal construction permits. The new rules raise the bar in two areas that used to leave room: a large project can no longer be diluted into small parts, and the environmental commitment may require financial backing. Correcting course later is expensive, which is why the broader debate on planning rules people can actually follow applies here too. A practical sequence:
- Scope the study under the correct category before committing to a budget or schedule.
- Present the project as a single whole so that it cannot be read as fragmentation.
- Budget for a possible environmental financial guarantee across construction, operation and closure.
- Confirm that your environmental consultant is listed in the Ministry's registry.
- Plan time for the community consultation and the public forum within the review.
