The SPARCCLE project will deliver adaptation and mitigation strategies for a just and climate-resilient Europe, as well as support policymaking for action on the socioeconomic risks posed by climate change.
By engaging policymakers, public and private sector stakeholders, and scientific experts throughout the project, SPARCCLE aims to generate actionable insights and recommendations for policymakers at all levels – European, national, and local, including the European Commission Joint Research Centre (JRC) – as well as for businesses, and civil society, based on state-of-the-art science. This involves iterative activities through the project’s lifetime such as co-design of scenarios, validation of results, and capacity building.
To bridge disciplinary divides, SPARCCLE is establishing new methodological frameworks that connect research communities working on climate impacts and risk in Europe. It combines bottom-up assessments of multidimensional climate vulnerabilities, risks, damages and adaptation with integrated assessment frameworks (IAFs) and leading multi-sectoral macroeconomic models. Through this approach, the project will strengthen Europe’s capacity to identify the characteristics of both sectoral and systems-level transformations required for climate-resilient and just development that reduces socioeconomic risks for Europe related to both sudden extreme events and slow onset processes.
The main goals of SPARCCLE are to:
- Accelerate new probabilistic emulators of climate hazards, damages and risks, incorporating cross-sectoral interactions, spillovers, and monetization of climate impacts.
- Develop granular socioeconomic projections, including gender and socioeconomic heterogeneities, and multidimensional vulnerabilities informed by empirical assessment.
- Develop insights on mitigation-adaptation synergies and trade-offs and sectoral risks, and provide region-specific recommendations on short- and long-term climate policy responses, considering energy security and import dependence.
- Foster co-creation with public and private stakeholders through knowledge transfer, capacity-building activities, and open science.
- Co-design stress-test scenarios that explore socioeconomic climate risks with stakeholders and policymakers, including sectoral stress tests.
Understanding Europe’s climate risk through stress test scenarios
The co-development of stress-test scenarios is a central theme of the project, cutting across the five substantive work packages in an integrative activity that explores plausible yet exceptional changes in risk factors across Europe. SPARCCLE will co-design stress test scenarios with key stakeholders, to explore high-impact components of the socioeconomic risks of climate change in Europe.
SPARCCLE brings together leading experts from across Europe
IIASA acts as the coordinator of the SPARCCLE project, responsible for overseeing project management and partner collaboration. Additionally, IIASA brings together expertise from four of its research programs, which actively contribute to the project’s implementation:
- Energy, Climate and Environment (ECE) - responsible for overall project coordination and communication activities, stakeholder processes, online tools and data systems, and integrated assessment modelling with the MESSAGEix model.
- Biodiversity and Natural Resources (BNR) - responsible for assessing land-use pathways and climate impacts on the forestry sector.
- Advancing System Analysis (ASA) - responsible for investigating the impacts of climate extreme events on the fiscal stability of national economies.
- Population and Just Societies (POPJUS) - responsible for leading the development of scenarios and datasets of socioeconomic development and vulnerability.
