The Just Transition Compass was launched at a networking dinner in Belém during COP30. Developed by LACLIMA and Climate Strategies with support from GIZ and the COP30 Presidency, the Compass is an operational tool designed to help negotiators and implementers translate high-level climate ambitions into fair, inclusive transitions. It focuses on governance choices regarding participation, safeguards, and the distribution of benefits and burdens to prevent the creation of new 'sacrifice zones'. The launch followed a series of dialogues in Brasília, Panama, Bonn, and Addis Ababa, and serves as a foundation for continued collaboration on policy design and financing beyond the project's conclusion on 31 December 2025.

The Water Evaluation and Adaptation Planning (WEAP) platform is a scenario-based modelling tool used in 190 countries to integrate supply- and demand-side perspectives for water resilience. It enables users to simulate climate-driven scenarios, evaluate adaptation strategies such as infrastructure upgrades and demand management, and analyze trade-offs at the water-energy-food nexus through integration with the Low Emissions Analysis Platform (LEAP) and macroeconomic models. WEAP supports both top-down and locally led initiatives across various scales, from local watersheds to transboundary river basins.

The Community Energy Toolkit (COMET) uses participatory workshops and simulations to help communities in Africa, Asia, and the Pacific plan for the productive use of energy (PUE). By allowing households and micro-enterprises to trial appliances and tariffs, COMET provides developers with demand-side intelligence—such as demand curves and willingness-to-pay—to reduce the risk of under-utilisation and under-recovery of revenues. A deployment in Pos Titom, Malaysia, demonstrated how testing specific enterprise options like grinders and ice-making can create concrete income pathways and decision-ready inputs for implementers. Across 110 communities in six countries, this co-creation approach has been linked to higher early-life utilisation and improved billed revenue.

The Stockholm Environment Institute and the FAO have developed a WEAP PlugIn that allows for the calculation of water stress at the sub-basin level rather than just on a country-wide basis. By disaggregating data, water resource managers can better visualize spatial variations in water stress and test the impact of different management strategies, such as reducing canal losses or accounting for population growth. The tool uses the Flow Duration Curve (FDC) Shift method to incorporate environmental flow requirements into its calculations. The briefing demonstrates the tool's application using the Senegal River basin and lists recommendations for its implementation in other basins.

WASH-Flows is a Microsoft Excel-based tool developed under the Bolivia WATCH Program to bridge the gap between household-level WASH data and watershed-scale planning. It transforms qualitative household information into quantitative data to assess service vulnerability, estimate environmental contamination loads, and provide water demand and wastewater flow data for water resources management software. While developed for Bolivia and currently applied in the Tupiza, Pampa Huari, and Choqueyapu-La Paz watersheds, the tool is intended for use in low- and middle-income countries across rural and peri-urban settings.

WASH-Flows is a Microsoft Excel-based tool developed under the Bolivia WATCH Program to bridge the gap between household-level WASH data and community-scale watershed planning. It transforms qualitative information into quantitative data to assess service vulnerability, estimate pollution loads, and calculate water demand and wastewater flows. While currently in beta and applied in three Bolivian watersheds, the tool aims to support local governments and planners in rural and peri-urban environments to prioritize interventions and align with SDG 6 targets.

The Stockholm Environment Institute (SEI) has developed 'Konsumtionskompassen' (version 1.0), a digital tool that estimates the climate impact of household consumption across all Swedish municipalities down to the postal code level. The tool covers over 110 consumption categories, identifying 'hotspots' to help local governments implement targeted climate measures. Findings indicate significant disparities in footprints between resource-poor and resource-rich areas, and highlight that while average footprints are similar across municipalities, the composition of emissions varies by urbanisation and geography.

Global Shipping Watch is a data platform that matches cargo records with AIS vessel movements to attribute maritime emissions to specific companies, products, and routes. It aims to overcome barriers to decarbonization by providing transparency for scope 3 emissions reporting and sustainable supply chain management. The initial 2019 data release covers US imports and exports, as well as exports from Brazil, Chile, Peru, and Indonesia.

Global Shipping Watch is a data platform that matches cargo records with vessel movements from the Automatic Information System (AIS) to attribute maritime emissions to specific companies, products, and countries. By addressing the previous inability to associate emissions with individual cargo owners, the tool aims to improve scope 3 carbon reporting and life-cycle analyses. The initial 2019 data release covers US imports and exports, as well as exports from Brazil, Chile, Peru, and Indonesia.

The Stockholm Environment Institute developed Aid Atlas to address the complexity of tracking global development finance. While the OECD's Creditor Reporting System provides the most comprehensive data, its design makes it difficult for the public and smaller recipient countries to use. Aid Atlas transforms this data into an intuitive, visual tool to help decision-makers in developing countries understand aid flows and focus on whether funding generates lasting positive impacts.

The Stockholm Environment Institute has developed the Empowerment in WASH Index (EWI) to address gender data gaps in the WASH sector. The tool measures agency, participation, and empowerment across individual, household, and community levels. A case study in Banfora, Burkina Faso, demonstrated that the EWI can identify specific drivers of disempowerment—such as lack of input in expenditure decisions and work balance—to help municipalities design gender-integrated strategic plans. The findings suggest a positive correlation between higher levels of female empowerment and the use of improved sanitation and on-premises water sources.

Aid Atlas is an interactive online platform developed by the Stockholm Environment Institute to visualize international development finance flows. It aims to make complex aid data more accessible to government officials in recipient countries, researchers, and international organizations through alluvial diagrams and tailored profile pages. By increasing transparency and highlighting financing gaps, the tool seeks to improve the overall effectiveness of the approximately US$ 146 billion annual global development finance budget.

The Stockholm Environment Institute has developed a platform based on the Water Evaluation And Planning (WEAP) system that allows water managers to model the effects of management options on aquatic habitat and species viability. The tool generates complete aquatic habitat assessments by comparing daily hydraulic, substrate, and temperature conditions against ideal conditions for species at specific points. It has been applied in California's Santa Clara Valley Water District to evaluate regulations affecting steelhead and chinook salmon, and is being used in the South Fork Eel River to analyze the impacts of instream flow requirements and cannabis policies on Coho and Chinook salmon. The tool is intended to support compliance with laws such as the California Environmental Quality Act and the Sustainable Groundwater Management Act, as well as restoration projects in the Mid Klamath Watershed.

The LEAP-IBC is an integrated planning tool developed by the Stockholm Environment Institute in collaboration with the US EPA and the University of Colorado. It extends the LEAP software by combining emission scenarios with the GEOS-Chem global atmospheric chemistry transport model and exposure-response functions. The tool allows users to characterize national emissions of greenhouse gases and short-lived climate pollutants (SLCPs), explore mitigation scenarios, and estimate resulting benefits in terms of avoided premature deaths, reduced crop losses for wheat, rice, maize, and soybean, and changes in global radiative forcing and temperature. While the core LEAP platform is applicable globally, the IBC component is currently available for 71 countries, with 12 countries using it specifically for the Climate and Clean Air Coalition's SNAP Initiative.

The Stockholm Environment Institute has developed Resource Value Mapping (REVAMP), a tool designed to help urban planners and investors identify the economic and material value of resources recoverable from sewage sludge, faecal sludge, and organic solid waste. Unlike previous tools, REVAMP operates at a city-wide scale and is specifically tailored for the Global South by incorporating on-site sanitation data. A 2016 trial in Kampala, Uganda, demonstrated that 100% collection of the city's organic waste could generate significant daily revenues and substitutes for firewood and chemical fertilizers, with solid combustion fuel offering the highest potential daily revenue of US$225,500.

The Energy Policy Simulator is a real-time, open-source tool that measures the cost and emissions impacts of over 50 climate and energy policies across all greenhouse gas emitting sectors in the U.S. The model, which is peer-reviewed by several national laboratories and universities, allows users to create custom policy scenarios using publicly available data and visualize results via a web application.

The briefing presents Transformative Transparency, a data-driven platform developed by the Stockholm Environment Institute and the Global Canopy Programme. It aims to increase transparency in the trade of agricultural commodities—specifically those linked to deforestation—by linking production landscapes to consumer countries using customs data, bills of lading, and subnational production data. The platform is designed to help investors, retailers, governments, and consumers identify risk factors and monitor sustainability commitments, such as 'zero deforestation' pledges, by providing a more comprehensive and cost-efficient alternative to footprint analyses and bespoke traceability systems.

The CAIT Equity Explorer is an online visualization tool developed by the World Resources Institute to support UNFCCC climate negotiations. It allows users to compare countries using a variety of metrics related to emissions, development capacity, and vulnerability through radar and column charts.

CCORAL (Caribbean Climate Online Risk and Adaptation TooL) is an open-access online system developed by the Caribbean Community Climate Change Centre (CCCCC) to help Caribbean government agencies, NGOs, and the private sector mainstream climate resilience into daily decision-making. The tool provides a screening exercise to prioritise climate-influenced activities, high-level guidance for both experts and non-experts, and a toolbox of over 70 climate risk management resources. It is specifically designed to fit into existing organisational processes such as national planning, budgeting, and legislation to avoid the high economic costs of climate inaction in the region.

The Resources and Energy Analysis Programme (REAP) is an environmental analysis tool that uses an environmentally extended input-output model to assess the global environmental impact of consumption at national, regional, and local levels. It tracks greenhouse gases, ecological footprints, and energy sources across the entire life cycle of products and services, including imports. The tool includes a scenario function to model the effects of political decisions, population changes, and shifts in consumption or transport habits. Originally developed in the UK in 2006, a Swedish version was introduced in April 2011.
