Resource economist UC Berkeley Professor Meredith Fowlie spoke about the complex regulatory challenges and ‘just transition’ dynamics of climate policy in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.” 

Harvard University Professor James Stock, who serves as Harvard's inaugural Vice Provost for Climate and Sustainability and director of the new Salata Institute for Climate and Sustainability, expressed his hopes for a smooth domestic energy transition during the newest episode of “Environmental Insights.”

This study offers the first consistent attempt to identify how energy sector decarbonization policies have affected the energy mix over the past four decades across more than 100 developing countries. 

The economist and HKS professor is passionate about solving what may be humanity's most important and perplexing problem: How to untangle fossil fuels from the global economy.

Low-carbon energy technology (LCET) startups could play a key role in accelerating India’s decarbonization. Yet, understanding of the LCET startup landscape and what shapes it remains low. This paper provides an analysis of the Indian LCET startup landscape to fill this gap.

ColdHubs, an innovative Nigerian agricultural enterprise that uses solar-powered refrigerated storage units to keep food from spoiling, is slowly but surely expanding to nearby West African countries. But it faces big challenges to scale up and finance its operations, company founder and CEO Nnaemeka Ikegwuonu told a Harvard Kennedy School audience celebrating the 2022 Roy Award winner.

Surging demand and dizzying price hikes have raised concerns that inadequate metal and mineral supplies may impede the clean energy transition. Given the urgency of reducing fossil fuel use, the science and policy worlds must solve two main challenges: how to ensure the availability and affordability of critical metals in the quantities needed, and how to manage the environmental impacts related to mining and processing them. The latter issue is likely to be much trickier than the former, argue Henry Lee and Xin Sun.

Joshua Schwartz and Sabrina Arias write that although Congress seems unable to act, enough states, cities and counties are mobilizing to make a dent in U.S. carbon emissions. The states, cities, counties, and towns that have committed themselves to upholding the Paris agreement currently release a majority of U.S. carbon emissions. If they do manage to meet their targets, they can make a meaningful difference.

Last week, U.S. Sen. Joe Manchin seemingly dashed Democrats’ hopes for congressional action to slow climate change. Sen. Bernie Sanders accused Manchin of “sabotag[ing] the president’s agenda”; Rep. John Yarmuth, when asked about the consequences of Congress not acting on climate change, said, “We’re all going to die”; and climate activists, as well as some Democrats in Congress, wondered if Manchin should be removed as chair of the Senate Energy and Natural Resources Committee.

The story of Iceland's transition from fossil fuels may serve as an inspiration to other countries seeking to increase their share of renewable energy.
