“Worldwide, less than 8% of folks are responsible for 50% of emissions”, according to Professor Stephen Pacala of Princeton, co-author of Stabilization Wedges.

This group has a higher annual income than even the average American. But the US has the highest per-capita energy consumption rate of any nation, out-consuming the five most populated nations combined. Quite recent studies have confirmed what many already knew: that more affluent people consume more energy, and generate more green house gas (ghg) emissions. Thus, making significant cuts in ghg (to slow warming trends and mitigate climate change) without big cuts in this group’s ghg emissions is a major challenge.

The impact of greenhouse gases on global warming in the short term, and the possibility of severe climate change in the medium to long term, promise to create significant and lasting hardships for everyone. But these hardships will fall hardest on the world’s poorest, who are the ones least responsible for ghg-induced climate change.

Corn ethanol was given a reprieve today when the Environmental Protection Agency (EPA) announced its proposed rule for implementation of the Renewable Fuels Standard or RFS2 that includes calculations of all greenhouse gas emissions (GHG) for all fuels. The RFS was signed into law as part of the Energy and Independence Act of 2007 which limits the maximum amount of corn ethanol to 15 billion gallons of the required 36 billion gallons by 2022.

There was palpable concern among corn ethanol proponents leading up to the ruling due to the controversy surrounding Indirect Land Use as well as the passing of the Low Carbon Fuel Standard (LCFS) last week by the California Air Resources Board (CARB), which was not favorable for corn ethanol.

We’ve all heard about the greening efforts of some pretty big companies, including GE and WalMart. But what’s behind the press releases and green logos? Though some corporate efforts may be greenwashing, many companies, both large and small, are making solid verifiable moves toward sustainability.

A panel held at UCLA this month, dedicated to sustainability in business, put this issue in the spotlight and revealed some useful information for companies looking to reduce their footprints. A few key points:
