The Green Mask Slips: Guyana’s 2026 Environmental Performance Index Score Exposes the Gap Between Biodiversity Branding and Climate Reality

While the Ali administration markets Guyana abroad as a biodiversity partner and low-carbon development model, Yale’s 2026 Environmental Performance Index ranks the country dead last of 177 nations on climate change mitigation — the single steepest ten-year decline in the entire index.
Guyana ranks 151st of 177 countries in the 2026 Environmental Performance Index (EPI), published by the Yale Center for Environmental Law & Policy in partnership with Columbia University — a score of 30.32, nearly 12 points below the Latin America & Caribbean regional average of 42.07, and 30th of 31 countries in the region. The figure has circulated widely in recent days, framed as proof that Guyana now trails even Haiti in environmental standing. That comparison is true on its face. But it is also the least interesting fact in the dataset.

The real story is not the overall rank. It is what sits beneath it: a country that performs credibly on the metrics tied to its standing forest, and catastrophically on the metrics tied to its oil economy. Those two facts sitting side by side, in the same government’s official messaging, in the same fiscal year, are the actual scandal — and they are Yale’s numbers, not ours.

The Number the Government Won’t Be Citing

Buried inside Guyana’s aggregate score is a single category result that deserves to be the headline: Guyana ranks 177th of 177 countries — dead last, full stop — on Climate Change Mitigation, the policy objective that measures a country’s trajectory on greenhouse gas emissions. Guyana’s score in that category is 3.67. Its ten-year change is -20.77, the steepest decline recorded for any country in the 2026 index — worse than Mongolia, worse than Laos, worse than any of the traditional laggards this ranking usually surfaces.
A related indicator, greenhouse gas emissions trend adjusted per capita, tells the same story from a different angle: Guyana scores 0.0, tied for the worst rank in the world (171st of 177), with a ten-year swing of -18.25. This is not a measure of how much a country emits in absolute terms — small, low-population states are structurally protected from that comparison. It is a measure of trajectory: whether a country’s per-capita emissions, adjusted for economic growth, are rising or falling. Guyana’s are rising faster, relative to its own growth, than almost anywhere else measured.

Forests: 36th of 177. Climate Change Mitigation: 177th of 177. Same country, same year, same government.

That divergence is the anomaly this report should be built around — not Guyana-versus-Haiti, but Guyana-versus-Guyana. On Forests, the country ranks a respectable 36th of 177, a score of 30.42 that reflects the genuinely low deforestation rate and the intact landscape integrity that has anchored every LCDS and carbon-credit pitch this government has made since 2009. The rainforest claim is not manufactured.

What is manufactured is the impression, cultivated in international forums and glossy biodiversity-partnership announcements, that this forest performance describes the country’s environmental trajectory as a whole. It does not. It describes one category out of twelve — and it is being used to paper over the worst-performing category in the entire index.

Reading the Category Breakdown

The table below sets out where Guyana’s 2026 EPI performance actually sits, category by category, against the field of 177 countries scored under this edition’s methodology (47 indicators across 12 issue categories, spanning three policy objectives: Environmental Health, Ecosystem Vitality, and Climate Change).

Source: Yale Center for Environmental Law & Policy / Columbia University, 2026 Environmental Performance Index, epi.yale.edu. Regional average (Latin America & Caribbean): 42.07.

The pattern is unambiguous. Guyana’s ecosystem assets — the forest it did not build, only declined to destroy — are propping up an aggregate score that would otherwise sit even lower. Strip Forests out of the picture and weigh Guyana purely on the categories shaped by government policy choice — energy procurement, emissions trajectory, industrial permitting — and the picture is one of the worst-performing petrostates measured anywhere in the 177-country field.

The Con: Selling Biodiversity While Failing Climate

This publication has tracked, across the Wales Gas-to-Energy project, the Karpowership rate escalation from 7.06¢ to 9.5¢ per kWh, and the broader energy dependency thread, a pattern of procurement decisions that entrench fossil generation rather than displace it.

The 2026 EPI’s Climate Change Mitigation collapse is the statistical signature of exactly that pattern.

A country cannot credibly market itself as a biodiversity and low-carbon partner to sovereign wealth funds and COP delegations while its own emissions trajectory — independently measured, methodologically transparent, published by one of the most cited environmental research institutions in the world — is rated the single worst of any nation on earth.

The Long Creek estate controversy, the Former Presidents Benefits Bill, and the GPL-InterEnergy sole-source contract are, on their face, governance stories about land, money, and procurement law. The EPI data gives them an environmental dimension that has been largely absent from the public conversation: every one of those threads sits downstream of the same executive posture — extraction and consumption decisions made with minimal independent oversight, dressed in the language of climate leadership abroad.

What This Is Not

Fairness requires two caveats, both of which strengthen rather than weaken the case.    First, Yale’s own FAQ states plainly that EPI scores should not be compared across editions as a time series, because methodology and indicator counts change with each release — the 2026 edition uses 47 indicators across 12 categories and 177 countries, versus 58 indicators, 11 categories, and 180 countries in 2024. Any claim that Guyana has “fallen” some number of places since the last edition is not supportable from this data and should not appear in this publication’s coverage. The story is not a decline narrative. It is a snapshot — and the snapshot alone is damning enough.
Second, the Forests and land-use performance is real and should be stated as such without qualification. The case here is not that Guyana’s environmental record is uniformly poor. It is that the government’s public messaging leans entirely on the one category where performance is strong, while remaining silent on the category — climate mitigation — where performance is, by Yale’s own numbers, the worst measured anywhere in the world.

The Accountability Question

Every biodiversity partnership announcement, every ART TREES carbon-credit sale, every appearance at an international climate forum trades on the credibility of Guyana’s forest numbers. None of that messaging, to date, has had to answer for the 177th-place climate mitigation score sitting in the same index. That is the question this newsroom will be putting to the relevant ministries: how does a government reconcile marketing itself as a global biodiversity and climate partner while its own independently measured emissions trajectory is rated worst in class among 177 nations?

Guyanese taxpayers, and the international partners being asked to fund and endorse these biodiversity arrangements, deserve an answer grounded in the same data the government cites when the numbers run in its favour.
