Making science diplomacy work

Science diplomacy has shifted amid growing geopolitical disruption, pushing scientists and diplomats toward more aspirational, pragmatic, and transactional approaches. In response, Québec announced at the 2025 UNESCO Global Ministerial Dialogue that it would build a network of research chairs in science diplomacy — a plan realized in March 2026 when the FRQ launched eight chairs covering themes from AI governance to Arctic diplomacy and food sustainability. This marks a shift from ad hoc engagement to structured policy capacity, now formalized in Québec’s international policy since June 2026.

As geopolitical rivalry strains the institutions that have underpinned global cooperation since 1945, José Manuel Durão Barroso argues that science can still hold the door open. In this piece, the former European Commission President makes the case for science diplomacy as a bridge across political divides, for open collaboration balanced with legitimate security concerns, and for treating knowledge as Europe’s “Fifth Freedom” — a strategic asset as vital to the continent’s future as the free movement of goods, people, and capital.

One can only hope that the war imposed by Russia on Ukraine will be brought to an end swiftly, that reconstruction of Ukraine as a sovereign state moves forward unimpeded, and that Russia, with its population of 140 million, will make earnest attempts to rectify its pariah status and re-join the rules-based international community.

When or if this will happen is not clear, but the EU should nonetheless be well prepared for the eventuality. This is true for all policy domains, but in this note we will focus upon the science and technology programmes of the EU and make some suggestions on how to use the instruments of science diplomacy for rebuilding the Ukrainian science system and reintegrating Russian scientists in the world science system, including the support of renewed scientific cooperation between Russia and Ukraine.

We face global, existential threats. From health emergencies to climate change, we see and feel them now. These threats can be managed and reversed. But that will require political will, global collaboration, and scientific breakthroughs at a scale not yet seen. Three experts shine a light on the missing links between science and international diplomacy. They ask how we can grow consensus when public trust in science and politics is fragile. And they make the case for science diplomacy.

The world faces some stark, geopolitical challenges. To tackle them we will need to draw on new, multilateral systems of cooperation and collaboration. A fundamental redesign of these multilateral systems is overdue – one that prioritizes the protection of the planet, together with humanity’s very survival. To succeed, any such redesign must optimize our ability to share, understand and apply scientific insight and evidence. The application of that scientific insight and evidence is the starting point for science diplomacy.

War is an extremely polarizing phenomenon that divides nuances into black and white. As Russian forces rolled into Ukraine, the Western response was to shut Russia out of virtually all partnerships and areas of cooperation. It seemed a justified reaction to a country seeking to reintroduce war into Europe after decades of peace. But, as inexcusable as the actions of the Putin regime are, we risk being blind to the nuances of the situation as we respond. It is difficult to employ rationality in times of war, when emotion takes the driver’s seat, but it is nonetheless crucial to ask the following questions in assessing our response: Do these actions stifle the Kremlin’s war objectives? Do they help Ukraine? What is the impact on humanity at large?
