This white paper quantifies the costs, benefits, and appropriate government funding associated with the transition to all passenger zero-emission vehicles (ZEVs). It assesses the key government support programs needed, for how long the need continues, and how public expenditures compare to societal benefits as the ZEV market develops.

To address the danger that greenhouse gas (GHG) emissions from aircraft pose to public health and welfare, the U.S. Environmental Protection Agency (EPA) is set to propose an aircraft CO2 emissions standard.

Acute flaccid myelitis (AFM) is a neurologic condition characterized by flaccid limb weakness. After a large number of reports of AFM in 2014, the Centers for Disease Control and Prevention began standardized surveillance in the United States to characterize the disease burden and explore potential etiologies and epidemiologic associations.

Global warming is expected to increase the frequency and intensity of severe water scarcity (SWS) events, which negatively affect rain-fed crops such as wheat, a key source of calories and protein for humans. Here, we develop a method to simultaneously quantify SWS over the world’s entire wheat-growing area and calculate the pro

Although recently published research addresses a range of issues relating to the corn ethanol lifecycle, much attention has focused on the result that corn ethanol production has a significantly better emissions profile than the U.S.

This study assesses the fuel efficiency of U.S. airlines on domestic operations in 2017 and 2018. Revenue passenger miles (RPMs) increased 10% and departures increased by 4% from 2016 to 2018. Fuel efficiency in terms of RPMs per gallon of fuel consumed improved by 3%.

This study examines the drivers of both the previous decline in global energy-related CO2 emissions, and their subsequent growth in recent years (in the EU, US, India and China), and argues that this trend was in neither case a good indicator of climate policy effort or effectiveness.

To achieve the Paris Agreement goals and limit global temperature rise this century to 1.5°C, the global economy must be rapidly transformed. A carbon price is needed to incorporate climate change costs into economic decision-making to significantly reduce U.S. greenhouse gas emissions, particularly in the electricity sector.

This paper summarizes and compares the two main test methods for aerodynamic evaluations of heavy trucks in the United States and the European Union: coastdown testing and constant-speed testing, respectively.
