Catherine is a Policy Fellow who coordinates the Climate Change Laws of the World project – the most comprehensive global resource on climate legislation and policy.


Catherine joined the Grantham Research Institute after nearly a decade of policy and advocacy work in the not for profit sector. Most recently, Catherine worked at the international environmental organisation CDP, where she led the organisation’s engagement with sub-national governments in Europe, the Middle East and Africa. Before dedicating her career to the fight against climate change, Catherine spent many years working in the field of human rights. From 2011 to 2017 she worked for Reprieve, where she led the organisations’ work on death penalty cases in the Middle East and South Asia, as well as leading investigations and campaigns against extra-judicial killings by the US and its allies.

Catherine holds an LLM from the University of British Columbia, where her research focused on the intersection of human rights and climate change in strategic litigation. During her time at UBC Catherine also co-founded the UBC Climate Hub with a group of incredible student activists, becoming the Climate Hub’s first full time member of staff and establishing the Hub as a new unit within the UBC Sustainability Initiative.

Catherine sits on the Board of the not-for-profit organisation the Climate Litigation Network.
