Think Sustainable Europe welcomes three new members

IEEP is proud to welcome BC3, the Green Tank, and IISD to the network of European sustainability think tanks.

Think Sustainable Europe was created to provide policymakers across the continent with sound, science-based analysis and recommendations, by combining insights and experiences from various countries and areas of expertise.

Launched in 2019, the network also serves as the idea generator behind Think2030, a nonpartisan, multi-stakeholder platform of policy experts from civil society, international NGOs, and the private sector.

The three newcomers join the founding members: the Institute for European Environmental Policy (IEEP), the Ecologic Institute, the Institute for Sustainable Development and International Relations (IDDRI), the Stockholm Environment Institute (SEI), and TMG – Think Tank for Sustainability.

In the year since it’s been active, the network has already held several high-level meetings at EU institutions, provided recommendations and analysis of major policy files and proposed the creation of an independent, green recovery scrutiny board to ensure a sustainable transition from the COVID-19 pandemic. In November, the network organised the second Think2030 conference, hosted by the Ecologic Institute online.
