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.

At MIT, Holdren Issues Call for Action on Climate Disruption

| October 29, 2010

John P. Holdren, President Obama's chief science and technology advisor, draws a grim picture of our world at the end of this century if we fail to start slashing greenhouse gas emissions that are ravaging the global climate. In a lecture at MIT, Holdren issued a call to action, arguing for a package of integrated measures to protect the environment. Holdren is on leave from Harvard Kennedy School's Belfer Center, where he was director of the Science and Technology Public Policy program.

Energy for Change: Introduction to the Special Issue on Energy & Climate Change

| Fall 2009

"Without energy, there is no economy. Without climate, there is no environment. Without economy and environment, there is no material well-being, no civil society, no personal or national security. The overriding problem associated with these realities, of course, is that the world has long been getting most of the energy its economies need from fossil fuels whose emissions are imperiling the climate that its environment needs."

Science and Technology for Sustainable Well-Being

| January 25, 2008

"I would urge every scientist and engineer with an interest in the intersection of S&T with sustainable well-being...to 'tithe' 10% of your professional time and effort to working in these and other ways to increase the benefits of S&T for the human condition and to decrease the liabilities. If so much as a substantial fraction of the world's scientists and engineers resolved to do this much, the acceleration of progress toward sustainable well-being for all of Earth's inhabitants would surprise us all."
