Transportation spending plan could weaken U.S. clean air rules

A Proximate Mirror: Greenhouse Gas Rules and Strategic Behavior under the US Clean Air Act

The development of climate policy in the United States mirrors international developments, with efforts to initiate a coordinated approach giving way to jurisdictions separately taking actions. The centerpiece of US policy is regulation in the electricity sector that identifies a carbon emissions rate standard (intensity standard) for each state but leaves to states the design of policies, incl...

Government Spending and Air Pollution in the US

This study examines the effect of the composition of federal and state government spending on various important air pollutants in the US using a newly assembled data set of government expenditures. The results indicate that a reallocation of spending from private goods (RME) to social and public goods (PME) by state and local governments reduces air pollution concentrations while the compositio...

Why Is Clean Air Clean?

Air exhibiting very low concentrations of light-scattering aerosol particles is occasionally observed even in industrialized regions. Evidence is presented that this very clean air results from highly efficient removal of aerosol particles coupled to the removal of water in precipitation.

Characterization of delay propagation in the US air transportation network

Complex networks provide a suitable framework to characterize air traffic. Previous works described the world air-transport network as a graph where direct flights are edges and commercial airports are vertices. In this work, we focus instead on the properties of flight delays in the US airtransportation network. We analyze flight performance data in 2010 and study the topological structure of ...
