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.

Khaled El-Enany, Director-General of UNESCO: “The world is not lacking scientific knowledge. What we need now are stronger systems to put that knowledge to work for people and the planet.”
Our read: The two reports land on the same point from opposite ends. The Decade’s own initiatives say their problem is coordination, not money; the open science numbers show commitments outrunning the machinery to track them by roughly two to one. Both describe a systems deficit rather than a knowledge deficit, which is exactly what the Director-General said out loud. It is also the same shape as the finding running through HLPF a week earlier: the pledge is easy to make and the follow-through is what nobody counts.

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

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 six summaries above cover the conference’s main two-day programme in full and are its public record. As of 17 July, UNESCO had published no recording of the Closing Ceremony and no outcome document or closing summary; if either appears, it will be linked here.
