Leo Mercer

Leo works on a variety of UK net-zero policy areas, including carbon pricing, just transition, the voluntary carbon market and decarbonisation of the land use sector.


Leo has a background in environmental science and geography and completed a PhD in Environmental Studies at Victoria University of Wellington in 2020. His thesis explored the role of carbon forestry, registered under the New Zealand Emissions Trading Scheme, as a land development option for Māori landowners. Subsequent to this, he was employed as a policy analyst at the New Zealand Ministry for Primary Industries on a work programme to develop an agricultural emissions pricing mechanism to support New Zealand farmers and growers to reduce emissions in line with statutory obligations.
