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.

Fires, Smoke, Floods, Droughts, Storms, Heat: America Needs a Climate Resilience Strategy

| May 02, 2021

In the face of advancing impacts of climate change — fires, smoke, floods, droughts, storms, and heat— Lara Hansen and Joel Clement argue for changing the way the country does business in every facet of the economy, with an eye toward reducing risk, increasing resilience, and ensuring equity and justice.

Harvard Project Co-Sponsors Webinar on Climate and Energy Policy in India

| Apr. 12, 2021

The Harvard Project on Climate Agreements co-sponsored a webinar on March 30, 2021: “The Future of Green India: Energy and Climate Change.” Hosting the event was the Lakshmi Mittal and Family South Asia Institute at Harvard University. The other co-sponsors were the Environment and Natural Resources Program in the Belfer Center for Science and International Affairs, Harvard Kennedy School — and the Harvard University Center for the Environment. The Harvard Global Institute provided support for the seminar and a larger project of which it is part.

Patenting and Business Outcomes for Cleantech Startups Funded by the Advanced Research Projects Agency-Energy

The authors examine the impact of the US Advanced Research Projects Agency-Energy (ARPA-E) on two outcomes for startup companies: innovation (measured by patenting activity) and business success (measured by venture capital funding raised, survival, and acquisition or initial public offering).
