Tom Ewing’s Environmental Update

* The US House is busy again this week on energy and environment issues with the Select Subcommittee on Chatter holding a hearing entitled, “Midterm Review and Update on the Corporate Average Fuel Economy Program and Greenhouse Gas Emissions Standards for Motor Vehicles,” Thursday, September 22, at 10 a.m. in HVC-210 of the Capitol Visitor Center. The hearing will examine the Corporate Average Fuel Economy (CAFE) program and greenhouse gas (GHG) standards set by the National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA).

* If you are a cow, you might be feeling a little beat up on lately, considering all of this messy methane business and global warming. Like it’s your fault, right, that Americans love milk and cream cheese and ice cream and hamburgers (make mine a cheeseburger). The US Dairy Production Stabilization Act of 1983 authorizes a national program for dairy product promotion, research and nutrition education. Is that in the same contradictory policy-class as tax breaks and subsidies to help expand petroleum and coal operations? Cow, uh, vapors and manure are significant sources of methane, a compound far worse than CO2 for trapping heat. USDA reported last week that in 2014, total milk production was 206,586 million pounds. California and Hawaii: 42,366.9 million pounds. I can’t comprehend those numbers, but how do you get this to change in a world with hungry people?

* A trillion tons. That’s the atmospheric limit for CO2 (and equivalent) concentrations. Since 1750 humans have added 600 billion tons. Beyond a trillion? Don’t think about it. And don’t get complacent about ratcheting way back to stop the next 400 billion. In fact, it can’t happen without CCS – carbon sequestration and capture. These are some of the lessons in an excellent webinar – “A Better Life with a Healthy Planet: Pathways to Net-Zero Emissions” – available from the CCS Institute, presented by David Hone, Chief Climate Change Adviser for Shell and a board member and former Chair of the International Emissions Trading Association (IETA). Mr. Hone’s presentation is engaging, analytical, big-picture and jargon free. Watch it.

Have a great Monday and a great week!
