Residents of four Colorado towns will vote on fracking bans Tuesday. Oil and gas production is growing in the western states, and what happens in Colorado is being closely watched in other shale-rich states.
The carbon bubble idea is an interesting hypothesis, Styles writes, but there are some flaws in the arguments Al Gore makes in its support. Carbon bubble or no, there's nothing wrong with investors wanting to track their carbon exposure, consider shadow carbon prices, or ensure they are properly diversified.

Smart parking uses low-cost sensors, real-time data collection, and mobile-phone-enabled automated payment systems that help drivers quickly find a parking spot, Rucks and Guevara-Stone write. The system reduces car emissions in urban centers by reducing the need for people to needlessly circle city blocks searching for parking.
The US will end financial support for new coal projects overseas, except in narrowly defined circumstances, to address rising greenhouse-gas emissions. Can clean energy alone alleviate energy poverty?
Three western states have joined British Columbia in a regional scheme to put a price on carbon and implement other emissions-reducing policies. If successful, it could be a model for other regions, but questions remain over the efficacy of taxing carbon.
