In the last few decades, urban sprawl, once regarded as largely a U.S. phenomenon, has spread across Europe. Now an emerging group of planners is promoting a new kind of development — mixed-use, low-carbon communities that are pedestrian-friendly and mass-transit-oriented.

If crucial climate negotiations later this year in Copenhagen are to have any chance of success, the U.S. must take the lead. To do that, President Obama needs to act boldly in the coming months.

Key developing countries have long been exempt from efforts to reduce greenhouse gas emissions. Now, as global climate talks move forward, that policy must change.

In response to industry pressure, the U.S. Food and Drug Administration has failed to set adequate restrictions on mercury levels in fish. Now the Obama administration must move forcefully to tighten those standards and warn the public which fish are less safe to eat.

Many environmentalists assume that putting a price on carbon and creating a renewable energy economy will require major public sacrifice. But the Sierra Club’s Carl Pope argues that a well-designed package of market reforms — not austerity — will lead to a prosperous, low-carbon future.

The clearing of Indonesia’s rain forest for palm oil plantations is having profound effects threatening endangered species, upending the lives of indigenous people, and releasing massive amounts of carbon dioxide into the atmosphere.

In a bold departure from past U.S. policies, President Barack Obama sees clean energy and “green jobs” as critical components of an economic stimulus strategy.

Even as they debut the next generation of hybrids and battery-powered cars, auto company executives are not confident that the American public will buy them.

Europe’s backpedaling last month on toughening its carbon trading system may have signaled the end of its leadership on climate change. Now, with a new administration and Congress, America appears ready to commit itself to tackling global warming.

Geologist Yong Yang has serious concerns about plans for a massive Yangtze River diversion project. When he went public with them, he found out how difficult it can be to challenge a government decision in China. The third in a series on Chinese environmentalists.

Although he finds the possibility unsettling, Canadian climate scientist David Keith believes large-scale geoengineering will eventually be deployed to offset global warming. In an interview with Yale Environment 360, Keith explains why scientists must begin researching an “emergency response strategy” for cooling an overheated planet.

A number of companies, including one headed by biologist and entrepreneur Craig Venter, are developing genetically engineered biofuels that they say will provide a greener alternative to oil. But some environmentalists are far from convinced.

The potential for electric vehicles has been talked about for decades. But a former Israeli software entrepreneur is developing a game-changing infrastructure that could finally make them feasible — a standardized network of charging stations where drivers can plug right in.

Gary Yohe is spending a lot of time these days studying the economic issues surrounding climate change. In an interview with Yale Environment 360, the Wesleyan University economist talked about why the world needs to start taking steps to adapt to climate change and why strong action must be taken despite uncertainty about the extent of the warming and its ultimate effects.

Environmentalists from Bill McKibben and Paul Hawken, to Fred Krupp and Frances Beinecke offer President Obama their advice on the priorities he should set for the first 100 days of his administration.

In evaluating an economic recovery package, the new U.S. administration and Congress must weigh any proposed spending on highways or mass transit or wind-power transmission routes on the basis of clear criteria that would assess just how green the projects will be.

Despite the creation of protected areas in the Amazon and other tropical regions, rain forests worldwide are still being destroyed for a simple reason: They are worth more cut down than standing. But with deforestation now a leading driver of global warming, a movement is growing to pay nations and local people to keep their rain forests intact.

The international commission charged with protecting the giant bluefin tuna is once again failing to do its job. Its recent decision to ignore scientists’ recommendations for reducing catch limits may spell doom for this magnificent and endangered fish.

After decades of living with fouled rivers and filthy air, residents of China’s Manganese Triangle are rising up and refusing to accept the intolerable conditions created by illegal mining activity. Their bold protests have shone light on the dark side of China’s economic boom. From Sichuan province, Chinese journalists Zhou Jigang and Zhu Chuhua report.

Despite daunting challenges, technology to harness the power of the waves and tides is now being deployed around the world from Portugal to South Korea to New York’s East River. These projects, just beginning to produce electricity, are on the cutting edge of renewable energy’s latest frontier: hydrodynamic power.

In an interview with Yale Environment 360, Amory Lovins, co-founder and chairman of Rocky Mountain Institute, says that world's biggest untapped energy source is efficiency. And retooling for energy efficiency will require \"barrier-busting\" at many levels. And government, Lovins says, \"should steer, not row.\"
