Environment and Natural Resources

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. 

Legal scholar Andrey Todorov, Postdoctoral Research Fellow with the Arctic Initiative, reflects on the recent agreement reached by United Nations delegates to protect biodiversity in international waters and its implications for the Arctic. 

Arctic Initiative Research Fellow Andrey Todorov analyzes options to integrate the ecosystem-based approach (EBA) with Arctic Ocean governance.

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. 

In an essay for Harvard Kennedy School Magazine, Henry Lee argues the policies China is pursuing to wean itself off reliance on fossil fuels may also benefit its quest for greater energy security.

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.

Carbon capture, utilization, and storage (CCUS) is very likely to be a key technology for achieving the Biden administration's goal of net-zero greenhouse gas emissions by 2050. But absent regulation requiring its use, CCUS needs to become more economical in order for deployment in the United States to expand significantly.

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.

Joel Clement writes that because the Biden administration  has moved to repair the damage done by the Trump administration, colleagues from around the global Arctic are optimistic once again about partnering with America on solutions to regional crises .

Joel Clement details the concerns surrounding the use of solar geoengineering to mask the effects of climate change and argues for using existing technology to quickly transition away from fossil fuels.
