On March 29, the U.S. Environmental Protection Agency (EPA) proposed a new rule setting stricter emissions standards for cars and trucks and requiring a reduction in the sulfur content of gasoline beginning in 2017. The proposal addresses health risks posed by breathing hazardous vehicle pollution, such as asthma and other respiratory infections that can cause premature death. Together, the more stringent sulfur limit and new emissions standards will lead to rapid improvements in air quality nationwide.

The Keystone XL pipeline is a controversial project that would transport tar sands oil (which is more corrosive than crude oil) from Canada through America's heartland to Texas, creating air, water, and public health risks in its wake. In the past two weeks, lawmakers have introduced bills in both the House and Senate to strip the decision on the Keystone XL pipeline away from the Obama administration. The bills, if passed, would short-circuit the regulatory permitting process and prevent the public from voicing their concerns about the public health and environmental risks of the pipeline.

Federal agencies have started feeling the impact of the across-the-board spending cuts, known as sequestration, that went into effect March 1. Plans to furlough employees and cut programs are underway at many of the agencies charged with issuing and enforcing public health and safety standards. For the U.S. Environmental Protection Agency (EPA), these additional funding cuts will further drain already decreasing resources and impair the agency's ability to protect our air, water, and health.
