To date, greenhouse gas (GHG) emissions, mitigation strategies and the accompanying health co-benefits in different economic sectors have not been fully investigated. The purpose of this paper is to review comprehensively the evidence on GHG mitigation measures and the related health co-benefits, identify knowledge gaps, and provide recommendations to promote further development and implementation of climate change response policies.

An overview of climate change mitigation opportunities in the world's buildings is presented, based on the key building-specific findings of the Fourth Assessment Report from the Intergovernmental Panel of Climate Change. Buildings and the building stock can play a major role in mitigating climate change in the short- to medium-term, since substantial reductions in CO2 emissions from their energy use can be achieved over the coming years.

A Global Survey of Building Energy Efficiency Policies in Cities is a resource for city officials around the world as they design new policies for building energy efficiency, or review existing ones. The research should help close the evidence gap regarding city-level activity in building energy efficiency. As such, it is designed to be accessible to those working in the field in general, including researchers.
