Convention-challenging research on the economics and financial risks of climate change by Kamiar Mohaddes, Director of the Global Executive MBA Programme and Associate Professor in Economics and Policy at Cambridge Judge Business School, was the Impact Award Winner at the inaugural Climate and Nature Research Showcase 2026 at the University of Cambridge.

The award to Kamiar, reflecting a series of studies he co-authored with the team at climaTRACES Lab, was for Overturning Consensus on the Country-Specific Economic Costs and Financial Risks of Climate Change. The research challenges conventional thought that climate change will only affect low-income countries near the equator while sparing cooler and wealthier countries, as well as the view that financial risks of climate change are decades out before being realised.

The Climate and Nature Research Showcase was held on 26 June, bringing together more than 140 University of Cambridge researchers on disciplines ranging from energy to law and from infrastructure to food. The event coincided with the end of London Climate Action Week.

Says one of the studies co-authored by Kamiar: “Quantifying the macroeconomic impact of climate change has been a focal point in academic and policy discussions since the early 1990s. The estimates of global GDP losses at future warming levels vary widely due to differing methodologies, complicating the formulation of effective climate policies. We bridge the gap between these varying estimates by quantifying country-specific annual per-capita GDP losses from global warming using the most recent climate scenarios of the Intergovernmental Panel on Climate Change (IPCC) under different mitigation, adaptation and climate variability assumptions. Motivated by the need to inform policy decisions, we hypothesise that without substantial mitigation and adaptation efforts, global GDP per capita could decline by up to 24% under high-emissions climate scenarios by 2100.”

Interdisciplinary research at the University of Cambridge

The research teams behind the papers are now part of the climaTRACES Lab, an interdisciplinary research initiative at the University of Cambridge that focuses on sustainability and nature research. The work of the lab, as reflected in this Impact Award, was cited extensively by the US Congressional Budget Office and in a letter to the Federal Reserve Board chairman by 25 members of Congress.

Another research report, done by the climaTRACES Lab and BCG (Boston Consulting Group), found that the cost of inaction in the face of climate change would by 2100 be 11% to 27% of cumulative GDP.

“Governments, businesses and people worldwide are paying the price for the storms, floods, heatwaves and droughts that are caused by climate change,” says the report. “Without investment to avoid future climate change, it’s likely that the world’s economic output will be severely diminished, threatening the livelihoods of billions of people. This report sets out the economic case for climate action – and how we can make it influence decisions today.”

Another paper co-authored by Kamiar suggested that, if nothing is done to reduce carbon emissions, up to 63 nations could have their credit rating downgraded by the end of this decade, including 3 notches for Germany and Sweden, and the US and Canada falling 2 notches, thereby making the cost of servicing (the already high) government debt significantly more expensive.

Engagement with other Cambridge researchers and beyond

“Cambridge Judge Business School is delighted for Kamiar and all his colleagues who contributed to this Impact Award,” said Professor Gishan Dissanaike, Dean of Cambridge Judge Business School.

“The award reflects research over several years on some of the most critical issues of this era, sustainability and economics, and demonstrates how Cambridge Judge academics engage with colleagues across the University of Cambridge and in the private sector to produce impactful research on these really timely issues.”
