  • The Movement for Urban Tree Expansion Is Growing

    Austin, Texas and King County, Washington are both participating in a new experiment by non-profit City Forest Credits (CFC) that uses creative financing to fund green spaces and tree-planting in cities. More specifically, CFC is piloting a new way that private entities can "offset their carbon emissions by buying credits for tree planting or preservation." Although the work is costly at the beginning, organizers hope the public benefits of more urban trees will make the program a worthy investment.

  • The First Quieter Megacity, Thanks to Electric Vehicles

    Massive investment in electric vehicles has reduced noise and air pollution in China. The megacity of Shenzhen, for example, is surprisingly quiet with its fleet of electric buses and ban on gas-powered motorcycles. However, the country’s reliance on coal means that EVs still plug into a dirty grid.

  • UPS Trucks Don't Turn Left and Neither Should You

    By having its drivers eliminate most left turns on their routes UPS has saved millions of gallons of fuel and reduced the output of tons of carbon dioxide. The company put the policy in place in 2004 after its vehicle routing software in all its trucks determined left turns wasted time and money stopping them also reduces accidents. These gains could increase exponentially if every driver eliminated left turns but that is probably unlikely.

  • What are coastal nuclear power plants doing to address climate threats?

    The World Nuclear Association counts 50 nuclear power plants being built, with 150 more in the planning stages. After the Fukushima nuclear disaster in 2011, nuclear plants on coasts began to be built with contingencies that account for sea-level rise. But new studies suggest that many such plans rely on outdated climate change projections.

  • Losing Earth: The Decade We Almost Stopped Climate Change

    In the late 1970s to late 1980s, activists, scientists, and politicians began to address the climate change crisis. For a decade, they attempted to ask the U.S. to commit to an international agreement to reduce emissions, and they almost succeeded. “In a single decade, they turned a crisis that was studied by no more than several dozen scientists into the subject of Senate hearings, front-page headlines and the largest diplomatic negotiation in world history.”
