At last, a Michigan State University study was just released to support what I've suspected all along: behavioral changes likely to be cheaper and faster, in the short term, at reducing carbon emissions than developing new technologies.
Thomas Dietza, Gerald T. Gardnerb, Jonathan Gilliganc, Paul C. Sternd and Michael P. Vandenbergh, of the Department of Sociology and Environmental Science and Policy Program, explored a short-term, high-potential solution for carbon emissions reduction. In the study, policy and behavioral intervention were considered for their ability to promote adoption and usage of existing carbon-emission reducing technologies in national residential buildings and for non-business travel in the U.S..
The study reports that household reductions via behavioral changes such as those recommended could result in US emissions reductions equivalent to the entire emissions of any country in the world outside of China and the U.S.
"Direct energy use by households accounts for approximately 38% of overall U.S. CO2 emissions...This is approximately 8% of global emissions and larger than the emissions of any entire country except China."
The study notes that the potential benefits have potential of cutting emissions in the United States by nearly 8% nationwide, and:
• Avoid overshoot of emissions targets
• Create demonstration effect
• Provide extremely, low-cost emissions reduction
• Buy time to explore other reduction and adaptation solutions
"National implementation could save an estimated 123 million metric tons of carbon per year in year 10, which is 20% of household direct emissions or 7.4% of U.S. national emissions, with little or no reduction in household well-being."
Notably, the study quantifies the carbon emissions reductions of these policy- and intervention-based behavioral changes as being greater than the amount of emissions reductions that would occur if all petroleum refining for steel and aluminum processing (the largest industrial emitter) in the US were to cease.
"We find that the national reasonably achievable emissions reduction (RAER) can be approximately 20% in the household sector within 10 years if the most effective nonregulatory interventions are used. This amounts to 123 MtC/yr, or 7.4% of total national emissions--an amount slightly larger than the total national emissions of France. It is greater than reducing to zero all emissions in the United States from the petroleum refining (69 MtC), iron and steel (38 MtC), and aluminum (13 MtC) industries, each of which is among the largest emitters in the industrial sector. The cost of achieving such a reduction through behavioral change may be far lower than the cost of many alternatives."

In Fred Pearce's, "
4:30 am - Abruptly, my partner and I are delivered instantaneously out of our respective dreams by screeching fire alarms and onto our feet. I throw open the door. (Did I think to feel it first? No! So much for grade-school fire safety training.) Smoke so thick I can not see across the living room. We are in a flurry of cursing; scrambling for cell phones, shoes and clothes; holding our breath to run across the living room and open windows. We make for the door running as I'm dialing 911.
Each pound of trash you throw away will emit approximately 0.94 pounds of carbon dioxide equivalent in the form of methane, and the average person in the U.S. throws away over 1,130 pounds of waste per year. For every person in the U.S., about 1,060 pounds of CO2 equivalent comes from the garbage we throw out every year.




In the next 66 days, we have a choice. We can go on with our lives, as we always do. Or we can do something fast and turn things around. To curb climate change, we must convince our world leaders to sign--and fulfill--an agreement at the Copenhagen Climate Conference (or "COP15"). It's up to us to let them know that we demand nothing less.
Climate of Change is one place to start. Take a step. Then document what you've done here. Give the movement a push and show others how you've done it. You can make an impact with a tweet and a Facebook status message, or a sign in your window and a phone call to President Obama. Be a part of the public outcry.
