WRI established its U.S. office in 1982. We work to improve water quality, increase awareness of local climate change impacts, and identify cost-effective emissions-reduction opportunities in the United States.

A new federal report reveals alarming statistics on climate change. According to the 3rd National Climate Assessment, released in draft form today from the U.S. Global Change Research Program, the world could warm by more than 12°F by the end of the century if action isn’t taken to reduce greenhouse gas emissions.

“The evidence is clear and mounting,” said WRI’s president, Andrew Steer, in response to the report. “The United States sits at the center of the climate crisis. Record heat is devastating crops, rivers are drying up, and storms are bearing down on our cities. Climate change is taking its toll on people and their economies, and will only become more intense without a strong and rapid response here in the United States and around the globe. It’s not too late to take action, but given lags in policy and geophysical processes, the window is closing.”

This assessment comes on the heels of the National Oceanic and Atmospheric Administration’s (NOAA) announcement earlier this week that 2012 was the hottest year on record for the contiguous United States. According to NOAA’s National Climate Data Center, the country saw 356 all-time temperature highs (and only four all-time lows) tied or broken and experienced 11 extreme weather events each causing more than $1 billion in damages.

Here are a few of the report’s key findings:

Natural ecosystems provide essential services for our communities. Forests and wetlands, for example, filter the water we drink, protect neighborhoods from floods and droughts, and shade aquatic habitat for fish populations.

While nature provides this “green infrastructure,” water utilities and other decision-makers often attempt to replicate these services with concrete-and-steel “gray infrastructure”—usually at a much greater cost. Particularly where the equivalent natural ecosystems are degraded, we build filtration plants to clean water, reservoirs to regulate water flow, and mechanical chillers to protect fish from increasing stream temperatures. And even though healthy ecosystems can reduce the operational costs of these structures, investing in restoring or enhancing various types of green infrastructure is rarely pursued—either as a substitute for or complement to gray infrastructure.

Despite America’s history of reliance on gray infrastructure, now is a critical time to tip the scales in favor of a green infrastructure approach to water-resource management. Investing in the conservation and improved management of natural ecosystems to secure and protect water systems can keep costs down and create jobs. Green infrastructure can also provide a suite of co-benefits for the air we breathe, the places we play, the wildlife we share our landscapes with, and the climate we live in.

According to new data, 2012 was a chart-topping year for the United States – but not in a good way.

The National Oceanic and Atmospheric Administration’s (NOAA’s) National Climate Data Center (NCDC) recently declared 2012 to be the hottest year on record for the contiguous United States. This year shattered the previous record temperature, set in 1998, by 1.0°F. The year was also marked by 11 extreme weather events that each caused more than $1 billion of damages.

In a year that brought the United States record-breaking wildfire activity, an ongoing drought, and Hurricane Sandy, perhaps these announcements aren’t surprising. But they are troubling: Record-breaking temperatures and the rising frequency of extreme weather events illustrate that climate change is happening. These trends are expected to worsen the longer we delay serious action to reduce carbon pollution.

Take a look at a few of the figures illustrating the intensity and impacts of 2012’s extreme weather and climate events:

Zipcar’s $500 million acquisition by Avis-Budget Group announced last Wednesday is a watershed moment for the car-sharing industry. What will it mean for car sharing?

Barely 10 years ago, no one knew whether car sharing could even work in North America, let alone become a staple of trendy and pragmatic urban living. Yet today Zipcar, plus dozens of innovative start-ups like City CarShare, PhillyCarShare, I-Go, and CommunAuto, have grown into robust community assets in every major U.S. and Canadian city.

Car sharing has made an indelible mark on how we live in cities. Membership exceeds one in five adults in many urban neighborhoods from Montreal to San Francisco. Each shared vehicle in North America has been shown to replace nine to 13 personal cars, and reduce driving by an average of 44 percent – as members pocket the savings and choose to walk, bike, and take public transit.

Zipcar has been at the forefront of this transformation. Launching in Cambridge, Mass., with a handful of lime-green Volkswagen Beetles, the feisty start-up pioneered early innovation, catalyzed massive scale-up around the world, and helped inspire a whole movement toward shared access to everything from houses to bicycles to parking spaces—and even pets.

The U.S. Environment Protection Agency finalized the Boiler Maximum Achievable Control Technology (MACT) rule today to protect people from exposure to toxic air pollution from industrial, commercial, and institutional boilers. By encouraging industry to use cleaner-burning fuels and to make efficiency improvements, Boiler MACT will modernize U.S. industry, reduce toxins, and cut carbon pollution.

The Boiler MACT rules, which are required by the Clean Air Act amendments of 1990, will only target the most significant sources of toxic air pollution. Most boiler-based emissions come from a small handful of very large industrial and commercial facilities that operate coal, oil, and biomass-fired boilers. As such, according to EPA:

  • Fewer than 1 percent of all U.S. boilers will be required to reduce their emissions to levels that are consistent with demonstrated maximum achievable control technologies, or MACT standards. Operators of these types of boilers will have three years to reduce toxic air pollution and meet new emissions limits.

  • A larger subset of U.S. industrial, commercial, and institutional boilers (roughly 13 percent) would not be required to meet the specific MACT standards, but would need to reduce their toxic air emissions through other means (as described below).

  • About 86 percent of all U.S. boilers are relatively small, limited-use, or gas-fired boilers, and are not covered by the new rules.

Defining the Shale Gas Life Cycle

A Framework for Identifying and Mitigating Environmental Impacts

In this working paper, WRI proposes a life cycle framework for shale gas. This life cycle spans exploration to well closure/site remediation, and from production to use. Readers may use the life cycle boundary for their own assessments of shale gas impacts.

In addition, WRI compares its...
