Natural Gas and Global Warming: A Review of Evidence Finds that Methane Leaks Undercut the Climate Benefits of Gas

Natural gas has been touted as a “bridge fuel” that can help the United States and the world reduce emissions of global warming pollutants during the transition to truly clean sources of energy. The “bridge fuel” argument, however, hinges on a critical assumption: that the climate impacts of natural gas are modest. Natural Gas and Global Warming reviews recent studies that have challenged that assumption, and finds that natural gas production, transportation and storage result in major leaks of methane to the atmosphere that erode or nullify the climate benefits of shifting to natural gas.

Lighting the Way 4: The Top States that Helped Drive America’s Solar Energy Boom in 2015

The states with the most solar capacity aren’t necessarily those with the most sunshine – they are the states that have adopted policies to make it easy and affordable for people, businesses and utilities to “go solar.”

Drive Clean and Save: Electric Vehicles Are a Good Deal for California Consumers and the Environment

Electric vehicles (EVs) are clean, fun to drive, never require a stop at the gas station, and are a key part of California’s strategy for reducing greenhouse gas emissions from transportation, the state’s biggest source of climate-altering pollution. Today’s mass-market battery electric vehicles are also a good deal and will likely save money for consumers compared to similar gasoline-powered vehicles.

A New Way Forward: Envisioning a Transportation System without Carbon Pollution

New technologies, new tools and emerging social trends make it easier than ever before to envision how America might transform its transportation system to one with little to no impact on the climate. With America facing an urgent imperative to eliminate carbon pollution to meet the terms of the Paris climate agreement, now is the time for action. Our report, A New Way Forward: Envisioning a Transportation System without Carbon Pollution, makes the case that America has the tools and strategies it needs to eliminate carbon pollution from urban, light-duty transportation by 2050.

Fracking by the Numbers: The Damage to Our Water, Land and Climate from a Decade of Dirty Drilling

Fracking has led to tremendous environmental harm and put the health and safety of communities across the country at risk. Since 2005, according to industry and state data, at least 137,000 fracking wells have been drilled or permitted in more than 20 states. Fracking by the Numbers quantifies some of the key environmental and public health-related impacts triggered by fracking during the technology’s decade-long spread across the country, including water and chemicals used, wastewater production, methane emissions, and land disturbed.
