Making a Case for Investing in Nature: An Interview with Lydia Zemke

| Aug. 15, 2023

As a Predoctoral Research Fellow at the Belfer Center’s Environment and Natural Resources Program and Science, Technology, and Public Policy Program, Lydia Zemke has spent the last two years studying climate finance in developing countries. As she rounds out her time at the Belfer Center, Zemke she reflects on her research interests, her experience conducting fieldwork in Kenya and Costa Rica, and her advice for other early-career researchers.

Bering Strait Navigation and Conservation in Times of Conflict

| November 2022

As climate change and economic activity in the region accelerate in the Bering Strait region, the United States and Russia have a common interest in mitigating these shared environmental risks. A November workshop hosted by Harvard Kennedy School’s Arctic Initiative, the Wilson Center’s Polar Institute, and the World Wildlife Fund (WWF) brought together seventeen experts to explore potential actions that the United States and Russia could pursue, jointly or independently, to protect the Bering Strait’s sensitive marine ecosystem and coastal communities.

Policy Spillovers, Technological Lock-In, and Efficiency Gains from Regional Pollution Taxes in the U.S.

| December 2022

We used the US-TIMES energy-system model in conjunction with integrated assessment models for air pollution (AP3, EASIUR, InMAP) to estimate the consequences of local air pollutant (LAP) and carbon dioxide (CO2) policy on technology-choice, energy-system costs, emissions, and pollution damages in the United States. We report substantial policy spillover: Both LAP and CO2 taxes cause similar levels of decarbonization. Under LAP taxes, decarbonization was a result of an increase in natural gas generation and a near-complete phaseout of coal generation in the electric sector. Under a CO2 tax, the majority of simulated decarbonization was a result of increased electric generation from wind and solar. We also found that the timing of the CO2 and LAP taxes was important. When we simulated a LAP tax beginning in 2015 and waited until 2025 to introduce a CO2 tax, the electric sector was locked into higher levels of natural gas generation and cumulative 2010–2035 energy system CO2 emissions were 8.8 billion tons higher than when the taxes were implemented simultaneously. A scenario taxing CO2 and LAPs simultaneously beginning in 2015 produced the highest net benefits, as opposed to scenarios that target either CO2 or LAPs, or scenarios that delayed either LAP or CO2 taxes until 2025. Lastly, we found that net benefits compared to business as usual are higher under a regional versus a national LAP-tax regime, but that efficiency gains under the regional tax are not substantially higher than those under the national LAP-tax policy.

Foundations for a Low-Carbon Energy System in China

How can China make good on its pledge to reach carbon neutrality by 2060? In Foundations for a Low-Carbon Energy System in China, a team of experts from China and the United States explains how China's near-term climate and energy policies can affect long-term decarbonization pathways beyond 2030, building the foundations for a smoother and less costly national energy transformation.

Biodiversity Loss is a Key Risk for Investors

| May 11, 2021

Awareness of biodiversity loss is increasing, but climate change still dominates investors' discourse on the environment. Joel Clement, a senior fellow at the Harvard Kennedy School's Belfer Center for Science and International Affairs, explains why we need to focus urgently on the biodiversity crisis. He also discusses why he came a whistleblower in 2017 and the aftermath of that decision.
