Science advice offers unique benefits to policymakers in tackling global challenges like climate change, say experts

Now more than ever, policymakers need good quality science advice to inform their decisions. Yet — as a new report by European academies highlights — the very policy issues for which scientific input is most needed are the ones where the science itself is often complex and uncertain.

This challenge is tackled by a new Evidence Review Report published today by SAPEA and entitled “Making sense of science for policy under conditions of complexity and uncertainty”.

The report highlights the fact that many of the world’s most pressing problems are also incredibly complex — including climate change, environmental pollution, economic crises and the digital transformation of societies. What’s more, the scientific knowledge around these areas can often be uncertain or contested.

The report was written by a multidisciplinary group of leading scientists, nominated by academies across Europe and coordinated by Academia Europaea, part of the SAPEA Consortium. It will inform the forthcoming Scientific Opinion from the European Commission’s Group of Chief Scientific Advisors.

Professor Ortwin Renn, the chair of the working group that wrote the report, said:

“Science advice for policymaking is in high demand and in urgent need. In today’s world of ‘fake news’, it is vital that we review the best available evidence and communicate it clearly to policymakers and the public. Where the science is uncertain, we must assess and explain those uncertainties, ambiguities and tensions. We live in democracies, where public scrutiny and accountability of both scientists and policymakers are inevitable and even desirable.”

The report highlights a number of key conclusions by the SAPEA working group:

• Science is one of many sources of knowledge that inform policy. Its unique strength is that it is based on rigorous enquiry, continuous analysis and debate, providing a set of evidence that can be respected as valid, relevant and reliable.
• Science advice supports effective policymaking by providing the best available knowledge, which can then be used to understand a specific problem, generate and evaluate policy options and monitor results of policy implementation. It also provides meaning to the discussion around critical topics within society. The advice works best when it is guided by the ideal of co-creation of knowledge and policy options between scientists and policymakers.
• The relationship between science advisers and policymakers relies on building mutual trust, where both scientists and policymakers are honest about their values and goals.
• Scientific knowledge should always inform societal debate and decision-making. Citizens often have their own experiences of the policy issue under consideration and should be included in the ongoing process of deliberation between scientists, policymakers and the public.
