What Plug-in Hybrid Sales Say About Our CO2 Emissions

What do the sales numbers of the Chevy Volt and the Ford Fusion Energi tell us about carbon reduction efforts in the United States?

In June, 2014, Chevrolet sold 1,777 of the 98 MPG Volts, compared to 26,008 for the comparably-sized 30 MPG Cruze.   Ford sold a record 1939 of the 88 MPG Ford Fusion Energis in June 2014, compared to 25,665 of the other 25 MPG Ford Fusion models. Read more…

Do Gasoline Consumers Deserve a Free Pass?

While public pressure mounts on universities and pension funds to divest from oil companies because of their role in causing global warming, consumers that buy gas from the oil companies are getting a free pass.   As long as a person isn’t driving a large SUV or Hummer, his or her gasoline usage is considered beyond reproach.  No moral stigma is attached to filling the gas tank up on a weekly basis, even though those 15 gallons of gas are releasing about 300 pounds of CO2 into the atmosphere.

There are four main reasons why personal gas consumption is not negatively judged—the subtle nature of carbon pollution, the necessity of a car for modern life, the ubiquity and scale of the problem, and the fact that most of us are afraid of being branded as hypocrites with respect to our own carbon usage.

Carbon Education for Consumers

Strategies for reducing global warming have focused mostly on stopping large oil infrastructure projects such as the Keystone XL pipeline, enacting carbon pricing strategies such as cap and trade, and promoting divestment from carbon extraction businesses.  Relatively little attention has been paid to effectively promoting voluntary carbon use reduction by American consumers, even though changing consumer carbon usage patterns holds the potential for enormous carbon emissions reductions.   On a per capita basis, Americans emit 17 metric tons (37,000 pounds) of CO2 per capita, roughly twice the European Union average and eight times as much as the Brazilian average.

The majority of Americans understand generally that it is important to conserve energy to help the environment, but lack the conceptual foundations to translate that notion into an understanding of personal CO2 emissions.  Consumers should be given the following basic conceptual tools to understand the volume of their carbon emissions: Using 1 gallon of gas releases 20 pounds of CO2 into the air; the 15 gallons in your car’s gas tank will spew 300 pounds of CO2;  1 kilowatt hour of electricity equals 2 pounds of CO2; 1 airplane mile = 1 pound of CO2.  A firm understanding these basic equivalencies, driven home by repetition, will give people a way to measure, understand and evaluate their personal carbon output, and the output of others.    Read more…
