About ZEST

The Zero-Emissions Sustainability Team (ZEST) is a research group led by Dr. Katya Rhodes in the School of Publication Administration and Institute for Integrated Energy Systems at the University of Victoria. ZEST consists of faculty, research associates, post-doctoral researchers, and graduate students, who collaborate with external researchers, policy-makers, advisory groups, and consultants. ZEST is a home base for students pursuing their Master's and PhD degrees in Public Administration. ZEST focuses on analyses of policies, technologies, and behaviours that enable low-carbon economy transitions in a rapid, cost-minimizing, and acceptable manner (see research projects and publications). Our research approach is two-fold: (1) we develop and use energy-economy models to assess impacts of climate-energy policy on emissions and the economy, and (2) we collect primary survey and interview data to analyze public and stakeholder opinion about climate-energy policies and low-carbon technologies. ZEST produces applied research outputs, translating technical results into lay language via policy briefs, op-eds, and media interviews. Our goal is to provide rigorous and timely information about climate solutions to change-makers.

Research Projects

Energy-economy modelling

We develop and use energy-economy models to inform the design of effective climate policies that achieve emission reduction goals at a low to medium cost. Our SSHRC Knowledge Synthesis project showcases the first Canadian inventory of all energy-economy models that are currently used by policymakers and practitioners. Using SSHRC Insight, we apply an open-access simulation model, CIMS, to propose climate policy pathways that achieve climate targets in an acceptable and efficient manner. We compare emission reductions with public support levels for the proposed pathways to develop a measure of political costs per tonne of emissions reduced. In collaboration with SESIT, we also improve electricity optimization and macroeconomic models and link them with CIMS in order to answer timely policy questions important to governments, practitioners, and policy advocacy groups

Public opinion

We study drivers and barriers to socio-political acceptance of climate policies and low-carbon technologies using large representative surveys of citizens and experts, interviews of government officials and practitioners, and community focus groups. Building from climate successes and addressing climate delays is key to implementing effective climate policy long-term. We consistently measure levels and identify drivers of public support and opposition to different types of climate, energy, and just transition policies using experimental and quasi-experimental survey designs. Under the Swedish Research Council grant on decoupling emissions from economic growth, we study the role of climate-economy trade-offs in climate policy support in various jurisdictions. We have also identified drivers of heat pump adoption and preferences for home decarbonization policies under SSHRC's Insight Development grant. Under ACET , we currently analyze energy visions and perceptions of climate-justice policy mixes in small and medium fossil-fuel dependent communities in Western Canada.

Comparative climate policy analysis

We use comparative policy analysis to identify the main features of climate successes and failures around the world. Our study on flexible climate regulations has been covered in Nature's highlights and served as a guide to develop market-based performance regulations around the world. Our study of climate governance frameworks in the United Kingdom and Germany has highlighted the importance of robust legislative frameworks that lead to both cost savings and emission reductions without strong opposition. Our narrative review of congestion pricing systems in OECD has suggested the most desired policy features that can both reduce congestion and contribute to climate change mitigation. We also consistently work on climate policy comparisons under different party platforms to design climate guides for voters.
