This methodology report describes the development and piloting of an integrated cost-benefit analysis (CBA) model designed to estimate the direct and indirect benefits of nature-based infrastructure (NBI)—such as conservation and reforestation—for road resilience in Indonesia. The model expands traditional CBA by incorporating 'non-road' benefits, including socio-economic and environmental externalities, to provide a more holistic view of the value of investing in climate-resilient infrastructure.

The Reinventing Fire (RF) transportation analysis outlines a methodology to estimate the techno-economic potential for efficiency gains in the U.S. transportation sector from 2010 to 2050. The report details modeling approaches for four subsectors—autos, heavy trucks, airplanes, and remaining sectors—focusing on 'Improved Design' and 'Improved Use' pathways to reduce fossil fuel consumption. It also includes a model for biofuel supply and cost, and calculates the overall societal net present value of these transitions.

This methodology report from the Stockholm Environment Institute introduces the Transnational Climate Impacts (TCI) Index, a framework designed to quantify country-level exposure to climate impacts that occur in one location as a consequence of climate events elsewhere. The report details the selection of nine indicators across four risk pathways—biophysical, finance, people, and trade—plus a global context indicator, to identify how international interconnections and dependencies create climate-related risks for nations regardless of their internal vulnerability.
