Rebuilding Better and Greener from the COVID-19 Pandemic

Key Tools for Policy Insights

The project brings together three modelling frameworks: CLEWs, OG-Core, and WEFM, to help policymakers explore trade-offs, test policy options, and translate evidence into practical strategies. Through country-level customization, training, and technical support, the initiative builds long-term, in-country capacity for integrated, data-driven decision-making.
