Germany's Polar research activities contribute to numerous initiatives and include links to climate and biodiversity protection. To prepare for future challenges and address the most pressing issues, the federal government launched a process to develop a new polar research agenda. On 19 May 2021, the steering group of the process including Ecologic Institute's Arne Riedel, handed over the concept paper on the "Changing Polar Regions" developed by over 100 experts to the Federal Ministry for Education and Research.

Nature-based solutions have been gaining attention as effective solutions to address important global challenges. A virtual breakfast briefing was held on 18 May 2021 with around 140 participants to discuss these topics and launch the Think2030 paper 'Using nature-based solutions to foster synergies between biodiversity and climate: Missed chances and opportunities for a sustainable future', co-written by the Institute for European Environmental Policy (IEEP) and Ecologic Institute.

The global COVID-19 pandemic has highlighted profound inequalities and vulnerabilities across the Global South, particularly in areas such as energy access, urban resilience, and environmental governance. Contributors to the IASS study analyzed challenges and potential pathways toward sustainable recovery, emphasizing the role of renewable energy, urban planning, and climate-smart economic strategies. The pandemic exposed systemic fragilities, demonstrating the urgent need for holistic, integrated approaches to development that address economic, environmental, and social dimensions simultaneously.

Focusing on urban and rural development at the regional and local level as key areas of application for climate services, the paper characterizes this valley of death and suggests options to bridge the gap. The authors, among them Ecologic Institute's Dr. Grit Martinez, suggest that reframing of the concept of climate services can help expand their applications and effectiveness, taking local non-climate challenges, opportunities and narratives into account.

The number of scientific climate advisory bodies is growing rapidly across European countries, including the establishment of one at the EU-level.
