A study led by the University of Alicante and the Mediterranean Center for Environmental Studies (CEAM) has measured how long environmental science takes to affect international policy. The researchers found that the average lag is seven years, highlighting a significant gap between research output and decision-making.

The study analyzes the barriers that separate scientific knowledge from environmental policy and its effective implementation. By identifying where these delays occur, the authors aim to help streamline the pathway from evidence to action.

While the source does not detail specific policy cases or regional differences, it underscores a systemic challenge: even when environmental science is robust, translating it into international governance is slow. The findings suggest that closing this gap could accelerate responses to pressing environmental issues.
