Valerie Karplus just published a new discussion paper entitled Sustaining the Global Energy Transition with the Harvard Project on Climate Agreements. The paper considers the implications of high interest rates, trade tensions, and energy geopolitics for the deployment of technologies to decarbonize industries worldwide and argues for strategies that maintain momentum that are connected with objectives beyond climate alone.  View the paper here .
