This policy brief by the South African Institute of International Affairs (SAIIA) argues for the integration of natural capital accounting (NCA) into global economic models and national systems of accounting. It highlights the critical importance of natural assets for low-income countries and Africa, and provides specific recommendations for the 2025 South African G20 presidency to champion the natural capital agenda, build conceptual consensus, address data gaps, and implement bioeconomy initiatives.

This research paper presents a policy-oriented simulation model designed to help Small Island Developing States (SIDS), specifically Barbados, plan for climate impacts and uncertain external drivers using a robust decision making (RDM) philosophy.

This policy brief introduces the Climate Impact Equity Lens (CIEL), a tool developed by the Stockholm Environment Institute to analyze climate change impacts on individuals rather than relying on aggregate regional or global economic models. CIEL identifies 'winners' and 'losers' by comparing the costs of climate damages against the savings gained from not investing in emission reductions. The brief argues that while many currently benefit from inaction, the majority of the global population will suffer net losses by 2100, and almost everyone will be a net loser by 2150, necessitating more stringent and fair climate policies to protect the most vulnerable.

The paper introduces the Climate and Regional Economics of Development (CRED) model, which analyzes the economics of climate and development choices with a focus on global equity, resource flows, and mitigation costs.
