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.

This study provides a whole-systems simulation on how to halve global CO2 emissions by 2050, compared to 2010, with an emphasis on technologies and costs, in order to avoid a dangerous increase in the global mean surface temperature by end the of this century.

CNN security expert and Cambridge mother of three Juliette Kayyem has plenty to say about Donald Trump, Boston's recovery, and staying safe this summer.

In developing countries, where the coronavirus pandemic is potentially at its most dangerous and costly, the authors call for governments to work with academic institutions to build and sustain computational modelling capacity.

Nicholas Burns, an old friend of Greece and well known in the country having served as US ambassador in Athens between 1997 and 2001, is now professor of practice of diplomacy and international relations at the Harvard Kennedy School and an adviser to Joe Biden’s campaign for the White House. Burns also served as US ambassador to NATO (2001-05) and under secretary of state for political affairs (2005-08). A few days ago he talked to Kathimerini from his home in Boston about Greece’s remarkable performance in tackling the crisis, the challenges Europe and the US are facing, President Donald Trump and how the pandemic is influencing the global balance of power. 

In a recent podcast interview, Robert Stavins and Scott Barrett discussed lessons from historic pandemics, how economists can help with policymaking surrounding the coronavirus, and what the “post-pandemic economic equilibrium” might look like. Resources Magazine has published an abridged version of their conversation.

As the novel coronavirus continues spreading, the whole world is preparing for the onslaught in similar ways—social distancing, working from home, panic buying at grocery stores. But people in different countries are also weathering this crisis in different ways, finding, for example, different products to hoard, different ways to pass the time, different people to blame and even different things to worry about.

As coronavirus continues to spread, the Trump administration has declared a public health emergency and imposed quarantines and travel restrictions. However, over the past three years the administration has weakened the offices in charge of preparing for and preventing this kind of outbreak.

The 1970 Clean Air Act established the basic architecture of the U.S. air pollution control system: It was the first environmental law to give the federal government a serious regulatory role, and it became a model for many subsequent environmental laws in the United States and abroad. In this article, the authors describe the evolution of air pollution control policy under this legislation with particular attention to the types of policy instruments used.

Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. The authors conducted a comprehensive assessment of CBECCS technology for China, with a focus on plant and fuel configurations (e.g., biomass ratios) and economics, as well as CO2 and greenhouse gas emissions and cobenefits for air quality.
