Computer-based models are valuable tools for investigating scenarios for aligning near-term actions and policies with long-term goals. Nonexperts who contribute to climate mitigation decision-making need to be able to evaluate these models and recognize that there is no “best” model that answers all policy questions.

Uncertainty is a common challenge to any long-term planning. This working paper takes stock of how long-term low-emission development strategies submitted to UNFCCC perceive and handle uncertainties, and how scenarios are used to illustrate different pathways that countries may take under uncertainty.

A growing body of research shows that healthy watersheds are a vital component of a well-functioning water supply infrastructure system. WRI’s Green-Gray Assessment (GGA) method allows stakeholders to value the costs and benefits of integrating green or natural infrastructure into water supply systems to improve performance.

New WRI analysis indicates that Mexico can save more than 25,000 lives and $5 billion in public health costs over the next 12 years by aggressively pursuing policies and actions that reduce air pollution and the greenhouse gas emissions that cause global warming.

This report provides a comprehensive analysis of the benefits and costs of restoring forests and landscapes in countries around the world, demonstrating how smart policies and innovative financing can help governments meet their restoration targets.

Over the past decade, India has taken several steps to address climate change while supporting long-term development objectives. This paper analyzes the climate change mitigation goals that have been set and the key policies that have been and are being implemented.

A new report offers evidence that the modest investments needed to secure land rights for indigenous communities will generate billions in returns—economically, socially and environmentally—for local communities and the world’s changing climate.
