Claire joined Climate Analytics in 2016 and is now the Co-Head of the Climate Policy Team and leads the Mitigation and Modelled Pathways analysis group. Her work includes assessing NDC ambition and working with modelled pathways that are consistent with the Paris Agreement’s 1.5°C warming limit. She has contributed to Climate Action Tracker and 1.5°C National Pathways Explorer, focusing in particular on net zero targets, the role of carbon dioxide removal and mitigation options in the land sector. She has also published peer-reviewed literature on these topics.
Throughout her time at Climate Analytics, Claire’s work has bridged the Climate Policy, Science and Climate Diplomacy teams, including by providing scientific support to Small Island Developing States during negotiations under the IPCC and UNFCCC.
Before joining Climate Analytics, Claire worked for the Potsdam Institute for Climate Impact Research (PIK) in the PRIMAP Emissions Team, where her work centred on analysing the mitigation components of the INDCs, with particular focus on the land-use sector. She has also worked as a policy analyst in a sustainability consultancy in London (the Carbon Trust), mainly focusing on renewable energy.
She holds an MSci in Natural Sciences from the University of Cambridge, with a specialty in geological sciences, and an MSc in Environmental Change and Management from the University of Oxford. Before joining PIK, she also did a traineeship in the European Commission, working in the energy and environment unit of the Secretariat General.

8 things to know about the state of climate action today
A major new report looks at climate action across all parts of the global economy to find that only electric vehicle sales are on track for 1.5°C.
G20 renewables target is no substitute for a clear fossil fuel phase out
The G20's new target of tripling renewables by 2030 is welcome, but the world will only meet its climate goals if this is coupled with a fossil fuel phaseout.
G7 moving faster on climate since last Summit, but behind schedule on ending coal and gas
As world leaders gather at the G7 Summit in Hiroshima this weekend, we take a look at progress made since the last Summit on cutting emissions and decarbonising power to see if they’re living up to their promises.
South Korea’s gas problem
South Korea is investing heavily in gas-fired power generation. This raises concerns of overlooking cheaper forms of generations – like renewables – and increasing the country's reliance on overseas fossil fuel imports.
Peak emissions before 2025: key messages from the IPCC’s Synthesis Report
The IPCC's final report of its Sixth Assessment Cycle is a comprehensive overview of the state of climate change and a roadmap for action in this critical. Our experts pull out the key messages.

Livin' in the future - delaying climate action and intergenerational justice
School kids around the world are taking to the streets demanding that the older generation step up efforts to tackle climate change, which they see as a major threat to their future. The teenagers of today will still be alive to bear the climate impacts of tomorrow - like sinking coastlines and cities, droughts, floods, crop failures - and will have an ever shrinking range of options to deal with the legacy of inaction on cutting carbon emissions.
