FACT SHEET Technologies to support climate change mitigation and adaptation

This fact sheet provides an overview of the software tools, online platforms, and research activities developed by the Stockholm Environment Institute (SEI) to support climate change mitigation and adaptation. The document details specific tools for energy planning (LEAP), water resources planning (WEAP), consumption-based environmental impact accounting (REAP), and knowledge sharing for adaptation (weADAPT), while outlining SEI's strategic focus on capacity-building and the integration of these tools to address sustainable development challenges.

• The Long-range Energy Alternatives Planning (LEAP) system is a software tool for integrated energy planning and climate change mitigation assessment. It is used globally by thousands of organizations, including cities and states, and has become a standard for countries creating Low Emission Development Strategies (LEDS) and informing Intended Nationally Determined Contributions (INDCs) for UN climate negotiations.
• The Water Evaluation And Planning (WEAP) system is used for integrated water resources planning and 'climate-proofing' the water sector. It allows planners to analyze water supply projects alongside demand-side issues, water quality, and ecosystem protection. SEI has applied WEAP in California, Peru, and Ethiopia, and has linked it with LEAP to analyze trade-offs between mitigation and adaptation.
• The Resources and Energy Analysis Programme (REAP) creates consumption-based accounts of environmental impacts by analyzing supply chains and re-allocating impacts from producers to consumers. It has been applied in Sweden, the UK, and globally. A version called REAP Petite is designed for individual households to build footprints based on energy use, travel, food, and goods consumed.
• weADAPT is a collaborative web-based platform for sharing knowledge on adaptation planning, featuring guides for climate information analysis and vulnerability assessment. The platform has over 2,500 members and 700 organizations across more than 190 countries, and includes links to over 2,000 global projects, articles, and case studies.
• SEI's Strategy 2015–2019 emphasizes expanded capacity-building and the creation of 'toolkits' to address complex issues. This includes a 'nexus toolkit' linking LEAP and WEAP to manage resource demands and mitigation/adaptation trade-offs, as well as initiatives linking LEAP with tools for short-lived climate pollutants (SLCPs) and analysis of fossil-fuel infrastructure investments.
