University of Cambridge (4CMR)

The Cambridge Centre for Climate Change Mitigation Research (4CMR) conducts programmes of research, education and engagement in the interdisciplinary area of coupled energy-economy-environment (E3) modelling, with an emphasis on assessing strategies of climate change mitigation. The over-arching intellectual theme is NewEDGE (New Economics of Decarbonising the Global Economy). This involves building the theoretical and empirical foundations for study of how economic, energy and environmental policies interact to drive decarbonisation of national and global economies, and reduce the risk of climate change. The research is done both in support of national and global policy assessments, and in collaboration other groups in the Tyndall Centre to create an integrated assessment model coupling climate science and E3 models.

4CMR is located within the Department of Land Economy of the University of Cambridge, with collaborators across the University, including the Cambridge Programme for Sustainability Leadership, Electricity Policy Research Group, Centre for Sustainable Development, Centre for Science and Policy, and Cambridge Conservation Initiative. The primary way by which we connect to the larger community of climate science and policy researchers is through the Tyndall Centre. 

Our activities rest on four Research Platforms, each conducting its own specialist research, but integrated within the E3 and NewEDGE activities. Current Platforms are in Economics and Econometrics; Environment and Health; Energy and Material Systems; and Decisions, Risk and Uncertainty. In addition, we have a vibrant programme of stakeholder engagement, informing public, private and third-sector organisations about the links between climate change and the inter-related issues of energy, economic and environmental policy.  

Our modelling evaluates short and long-term impacts of climate change policy on an array of indicators of social and environmental well-being. The key model is the Energy-Environment-Economy Model at the Global Level (E3MG). This model has evolved from research that includes contributions from Economics Nobel Prize laureates and the governor of the Bank of England, and reflects a rich heritage in research excellence. It was one of the mitigation models reviewed by the Intergovernmental Panel on Climate Change (IPCC) in their Fourth Assessment Report (2007). The IPCC were jointly awarded (with Al Gore) the 2007 Nobel Peace Prize.

Engineering cities


The Cambridge Centre for Climate Change Mitigation Research (4CMR)...Innovating Integrated Assessment Systems

Engineering citiesEconomics modelling The overall objective was to provide scenarios of economic activity at a city scale. This was modelled by adapting the existing E3MG and MDM global and UK models of economic activity that were developed in part during the first phase of the Tyndall Centre. In keeping with the overall integrated assessment framework, the economics model was driven by global scenarios of climate and socio-economic change. These was disaggregated to obtain measures of economic activity at a city scale but remained in the context of global scenarios of climate and socio-economic change. Of particular interest to urban planners and policy makers was the potential gains or losses from cities or nations using their own powers to explore city-scale mitigation strategies. The different scenarios of economic activity was used to drive the land use model and provided inputs to the emissions accounting models. Task duration: 01/10/2006 to 30/09/2008

Integrated Modelling


The Cambridge Centre for Climate Change Mitigation Research (4CMR)...Innovating Integrated Assessment Systems

The Tyndall Centre is committed to delivering high impact research, based on quality cutting-edge science, supported by a sustainable inter-disciplinary research culture. The 2nd Phase of the Tyndall Research Strategy (2006-09) was launched on the 4th May 2006, and comprises 7 research programmes designed to carry forward the work from phase 1. 4CMR was the lead partner in research programme 7 - Integrated Assessment Modelling. Dr Terry Barker lead the research programme, which developed and used the Community Integrated Assessment System (CIAS). The system links a climate and closed carbon-cycle model, a global energy-environment-economy model, an impacts tool and a down-scaling module. It is applied to analyse specific scientific and policy issues, including costs of stabilisation of atmospheric greenhouse gas concentrations, and post-2012 international climate policy options, including analysis of instruments designed to induce and diffuse technological change, allowing for the non-linear dynamic responses of the coupled climate socio-economic system.
