Opportunity 2030: Benefits of climate action in cities

Quantifying the benefits of city-level measures in buildings, transport and energy supply
Urban planning Renewable energy Building retrofitting Public transport Evaluation Greenhouse gas mitigation

A fundamental challenge for establishing the case for climate action in cities is the lack of suitable knowledge, evidence and calculation tools to understand the wider benefits of climate action and the interlinkages between other urban agendas, including other social and economic priorities such as poverty alleviation. This report presents analysis on the impacts of climate action through energy efficiency retrofit in residential buildings, enhanced bus networks and services, and district-scale renewable energy in major global regions, based on the development and utilisation of new impact assessment methodology tools. Evidence from this research demonstrates socioeconomic and health-related benefits of climate actions, broadening current definitions of societal well-being for decision- and policymakers.

The findings from this report present an evidence base for accelerated action for climate change mitigation measures. It equips city, national governments, private sector and citizens with several reasons for a joint collaborative effort toward the goals of low carbon development. This report will be followed-up by an extended work, complementing this first analysis to include assessments at the global scale. The results of this second phase of the work will be made available by the end of the third quarter of 2018, including through an online interactive dashboard.

All methodological details, assumptions and limitations of the Opportunity 2030 project analysis are published in an accompanying methodological report. Readers are encouraged to engage in, critically review and further build upon the methodologies and results in this report, and to make use of the content where possible as a tool for moving towards more holistic and participatory planning for sustainable development in cities.
