A climate conference in Oxford concluded last week that whatever we can do to slow carbon emissions, it won't be enough to stop accelerated sea level rise. In fact, a German scientist who's widely regarded as one of the world's foremost experts on sea level rise, said his best guess was 1 meter this century (a lowball figure compared to the latest projections for California)…

Some of the first calculations of the benefits of green roofs are coming back and they're even better than expected: replacing typical roofing materials with plants across a city the size of Detroit would be the equivalent of removing the pollution of 10,000 SUVs in a year. This study is the first to measure the amount of carbon that could be captured by the extensive…

This summer, somewhere in California, the state Energy Commission denied an application for a new urban natural gas-burning power plant, citing that urban solar (PV) might be a better alternative. The CEC said that new "peakers" were not obviously the most cost-effective or environmentally preferable option to close that city's energy reliability gap. For years, SPUR and a loose coalition of environmental advocates, led by…

Twenty years after Loma Prieta, are we better prepared for our next big earthquake? A new website takes a grassroots approach to the question.

Transportation-related greenhouse gas (GHG) emissions are the fastest growing source of emissions in the U.S., and are currently responsible for almost 30% of the nation's total GHG output. A new ULI report, Moving Cooler, presents different strategies for making our transportation systems more sustainable. It proposes nine categories for improvement, including pricing/taxes, land use and smart growth, transit improvements, ridesharing, intelligent systems, and more…
