Dear Chrysler: 5 Reasons Oil Prices Shouldn’t Affect Fuel Economy Standards

Lately, low gas prices have been making headlines across the country. Having dropped by more than $1.50/gallon over the last 6 months, there is certainly reason to be talking about them. So it was no surprise when the topic came up at the North American International Auto Show earlier this month in Detroit. The CEO of Chrysler, Sergio Marchionne, used the opportunity to call for rolling back vehicle fuel economy standards.

What I am keenly interested to hear are the ways in which Prime Minister Modi and President Obama plan to cooperate to address one of the biggest challenges facing the world today: climate change.

The Latest on Biofuels and Land Use: Progress to Report, but Challenges Remain

Carbon pollution caused indirectly by the increasing use of crops to produce biofuels has been a contentious topic for the last 7 years. In this post I look back at what we have learned since then about indirect land use change (ILUC) emissions, as this phenomena is generally called. The headline 7 years ago – that crop-based biofuels are far worse than fossil fuels – no longer holds. Read More
