About
The 2026 Global Conference of the International Decade of Sciences for Sustainable Development (IDSSD) is UNESCO's stock-taking moment two years into the UN Science Decade. It assesses progress, showcases science-driven solutions, and helps shape priorities toward a post-2030 development agenda.
Held in Paris in the second half of July, it extends the month's SDG-and-technology thread from Geneva and New York into the science-policy arena.
The opening in brief
The conference opened on 15 July, and the scorecard we were waiting for arrived with it. UNESCO announced the first Global Report of the International Decade of Sciences for Sustainable Development, its first stocktake two years into the Decade, and presented it in a launch session on the morning of 16 July. It is built on 397 endorsed scientific initiatives across 79 countries supporting all 17 Goals and USD 50 million in confirmed funding. Two of its findings are the ones worth carrying. The Decade is lopsided: Africa accounts for under 10% of its initiatives while holding 17.5% of the world’s population. And the binding constraint is not the one usually named, because 40% of the initiatives said their primary barrier was coordination rather than funding.
A second publication, the Open Science Outlook, got its own launch in a parallel session that afternoon, and it contains the sharpest counting of the conference. 81 countries have implemented UNESCO’s 2021 Recommendation on Open Science. But of governments reporting an open science policy framework, 79% have the framework, 41% have a plan to implement it, and only one in three has a monitoring mechanism. That is a policy commitment surviving into measurement barely a third of the time.
Figures are as UNESCO reported them at launch and are attributed to the specific publication that carries them: the initiative, funding, Africa and coordination figures are from the IDSSD Global Report; the open science figures are from the separate Open Science Outlook, which was launched in its own session the same afternoon. We have not read either report in full: UNESCO publishes both as view-only, so neither can be read outside its own online viewer.
What we watched, and how it turned out
- A mid-Decade scorecard. It arrived, and it marked its own homework honestly. The first IDSSD Global Report was announced on 15 July and presented at a launch session on 16 July. It is the closest thing to an official progress check on the Decade, and the two findings it leads with are uncomfortable ones: the Decade is lopsided, and the barrier its own initiatives name most often is coordination rather than money.
- Governing the frontier. The sessions on AI, quantum science and the governance of emerging technologies ran in the parallel thematic track on 16 and 17 July. UNESCO webcast the plenaries only, so that track has no public record and we hold none of it.
- Closing science divides. This ran through the whole programme, and the Global Report turned it back on the Decade itself: Africa holds 17.5% of the world’s population and under 10% of the Decade’s initiatives.
Session coverage
Our summaries of the conference’s main programme, ordered as they happened, drawn from the UNESCO webcast of the two main days, 15 and 16 July. Day 3 (17 July) was given over to partner-led thematic events and a half-hour Closing Ceremony. None of it entered the public record: the thematic events were not broadcast, and UNESCO’s webcast archive, which carries the two main days only, holds no recording of the closing.
The Decade can count its initiatives. It cannot yet count its results.
Two years in, UNESCO's stocktake counts initiatives, countries and dollars. Across two hours, nobody said “indicator.”

Ólafur Ragnar Grímsson says science cooperation is worse than at the Cold War's height, and answers it with a Chatham House style norm that nobody owns.
Read summary → 15 July · PlenaryA diagnosis with almost no diagnostics
Seven panellists were asked where science is failing the SDGs. They answered almost entirely without numbers, and the hardest figure in the room was a zero.

The Decade counted 397 endorsed initiatives, 79 countries and 29 government focal points, then said from the podium that the count is not the measure.

The Decade built its reporting plumbing in public, and UNESCO gave two different counts of its own network on the same day.

The main programme closes with three spoken messages and no outcome text, and names no next milestone between here and 2033.
