The revised Nationally Determined Contribution (NDC) of Mali outlines the country's updated commitments to the Paris Agreement for the 2020-2030 period. Mali aims to maintain its status as a carbon sink while increasing its mitigation ambitions across four sectors: energy, agriculture, forestry and land-use change, and waste. The document details specific emission reduction targets, adaptation strategies to combat desertification and food insecurity, and a comprehensive financing and monitoring framework, with a strong emphasis on gender integration and the involvement of non-state actors.

The Republic of Armenia's Third Nationally Determined Contribution (NDC 3.0) for 2026-2035 outlines economy-wide greenhouse gas (GHG) emission reduction targets and comprehensive adaptation strategies to address high climate vulnerability in a landlocked, mountainous region.

This guide, produced by the Stockholm Environment Institute's Tallinn Centre and the Ministry of the Environment, provides comprehensive recommendations for reducing food waste and food loss in Estonian schools. It targets school caterers, canteen staff, teachers, students, and school administrations, offering practical strategies for procurement, meal preparation, and educational integration to minimize waste.

The Stockholm Environment Institute has developed a tool based on the Water Evaluation And Planning (WEAP) system that allows water managers to model the impact of various management options on aquatic habitat and species viability. By analyzing daily hydraulic, substrate, and temperature conditions, the tool helps balance human water needs (urban, industrial, agricultural) with ecosystem health. It has been applied in California's Santa Clara Valley Water District and the South Fork Eel River to manage salmon habitats and evaluate the impact of policies, including cannabis cultivation and groundwater management laws.

A report by the Stockholm Environment Institute and partners arguing that staying below a 2°C warming limit requires rapid global greenhouse gas emission reductions, reaching essentially zero by mid-century. It emphasizes the technical feasibility of this transition and the necessity of North-South cooperation to ensure developing nations can expand energy access while decarbonizing.

This report by the Stockholm Environment Institute analyzes the European Union's proposed 2020 climate targets using the Greenhouse Development Rights (GDRs) framework. It argues that the EU's targets are insufficient to meet the 2°C warming limit and fail to account for the 'right to development' for the global South. The authors call for the EU to adopt a 'two-fold obligation' consisting of deep domestic emissions reductions and significant international financial and technological support to enable a low-carbon transition in developing nations.
