Ploy Achakulwisut

Ploy Pattanun Achakulwisut was a Scientist with SEI US and SEI Asia during 2019⁠–2023. Her research, stakeholder engagement, and communications focused on informing policymaking and multilateral governance on the need to phase out fossil fuels in line with climate, health, and equity goals.

She served as a coordinating lead author and lead analyst of the Production Gap Report series (2019–2023), which tracks the misalignment between governments’ planned fossil fuel production and the global levels consistent with the Paris Agreement. Her other research projects included evaluating subsidies’ role in locking in fossil fuel production and assessing the health impacts and inequities of air pollution from the oil and gas lifecycle in the US.

Ploy also co-led SEI’s Carbon Lock-in Initiative (2023), served as a working group member of the Lancet Countdown US Policy Brief series (2020–2023), and contributed to the 10 New Insights in Climate Science and UNEP’s Special Edition Frontiers Report (2023).
