More and more Americans are taking responsibility for their personal contribution to global climate change by driving fuel efficient cars, insulating their homes and switching to energy efficient lighting and household appliances.

However, even someone that’s gone to the extremes of traveling only on foot or bicycle and forsaking home heating, cooling, lighting, food refrigeration and cooking will likely shrink their carbon footprint by only about a third.  That’s because roughly two-thirds of Americans’ greenhouse gas (GHG) emissions are embedded instead in consumption of other goods and services, according to a recent analysis by the Center for Global Development (CGD), a non-profit policy research organization.

Most of us attribute our GHG footprint to the easily discerned energy we consume for personal transportation and home utilities.  Yet these so-called “direct” emissions account for just 36% of the average American’s annual GHG emissions which are equivalent to 21.8 tons of CO2.

The remaining 64% of GHG emissions are “indirect” and produced during the manufacture and production of literally everything else we consume, such as food, shelter, clothing, furniture, cars, bicycles, appliances, electronics, pets, toys, tools, cleaning supplies, medications, toiletries, entertainment and air travel.  The fact that indirect emissions typically take place somewhere distant and out of our sight, like in a factory overseas and during transport of products to the point of sale, underlies our lack of connection to them.

Meat Lovers Guide

Meat Lovers Guide to a Friendlier Climate-Change Diet
by Sarah (Steve) Mosko, PhD


A plant-based diet beats a traditional meat-based one hands down when it comes to trimming one’s contribution to greenhouse gases, but not everyone is willing to plunge head-long into a life of tofu dogs and bean burgers.

No doubt there are even plenty self-proclaimed vegetarians out there who guiltily sneak in some fried chicken, pork chops or a tuna melt from time to time and face self-recriminations afterward for satisfying such cravings at the expense of a warming planet.

The good news for either lapsed vegetarians or meat eaters with an environmental conscience is that meats and dairy products are not all created equal when it comes to the quantity of greenhouse gases (GHG) produced. In fact, a study just released by the non-profit organization Environmental Working Group (EWG) and titled “Meat Eater’s Guide to Climate Change + Health” reveals that by avoiding just the three worst GHG offenders – lamb, beef and cheese – even hardcore meat eaters can make a sizable dent in their diet’s climate change footprint.

EWG, in partnership with CleanMetrics, an environmental analysis firm, examined the “cradle to grave” lifecycle, from farm to retail to plate to disposal, of 20 popular foods in four categories – meats, fish, dairy and vegetable protein – and compared the GHG produced by each.

Ethanol Smells

What Smells About Ethanol Fuel

From President Bush on down, it seems everyone is talking up “biofuels”, especially corn-grain ethanol, as the panacea to the country’s energy woes… global warming, air pollution, increasing prices at the pump and dependence on foreign oil.

Automakers are promoting flex-fuel cars that run on either E85, a gasoline mixture that is 85% ethanol, or straight gasoline. Agribusiness giants like Cargill and Archer Daniels Midland are trumpeting their ethanol, fermented and distilled from corn, as they boost production to meet rising domestic demand. However, just because a fuel can be made from plants does not make it inherently “green” or ever plentiful enough to replace gasoline.

A reputable analysis concluded that conversion of all U.S. cropland to produce corn strictly for ethanol would not suffice to fuel the current fleet of American autos.1

Global warming is on the tip of many tongues these days, but so are hamburgers, pork chops, and fried chicken. As hybrid car sales are up and SUV sales on the decline, it seems Americans might be waking up to the reality that each of us bears some responsibility for climate change through our everyday consumer choices. John Robbins, the once heir-apparent of the Baskin-Robbins ice cream company, has authored bestsellers, such as The Food Revolution, detailing the detrimental environmental impacts of a meat-based diet. He and other experts make a strong case that food choices rank right up there with what car you drive in determining your personal contribution to global warming. A quick look inside the hamburger bun easily makes the point.

Massive Fossil Fuels Consumed to Produce Beef
Most U.S. beef comes from cows raised on factory farms where hordes of animals are crowded onto concrete lots and fed grains, mostly corn. The grains are also grown using industrial farming methods that rely heavily on application of synthetic nitrogen fertilizers and pesticides manufactured from Read the rest of this entry »
