A few weeks back, I was writing about CO2-friendly supply chains and saw the hefty list of U.S. companies that the Environmental Defense Fund had helped switch to recycled content in a drive to reduce paper waste across the nation.

Now, paper is back under the public eye in fuller force than ever because of its significant climate change footprint.
“Paper is a tremendously resource-intensive product to produce,” explains project manager Victoria Mills, “and the decomposition of paper in landfills generates methane, a greenhouse gas with 23 times the heat-trapping power of carbon dioxide.”

Methane is a potent greenhouse gas, 20 times more powerful than carbon dioxide at trapping heat. New Zealand scientists have developed a vaccine to cut down on livestock flatulence, which should help farmers avoid a proposed “flatulence tax” on the methane their livestock produces. New Zealand cows and sheep are responsible for about half of the country’s greenhouse gas emissions.

Looking for ways beyond changing lightbulbs and taking the train to help reduce your carbon footprint? Turns out we all could make a big difference in greenhouse gas emissions by not throwing out so much trash and composting our food waste.
That’s the message from “Stop Trashing the Climate,” a report prepared by The Institute for Local Self-Reliance, the Global Alliance for Incinerator Alternatives (GAIA) and Eco-Cycle, a non-profit recycler. The study finds that waste prevention and increased recycling and composting could reduce as many greenhouse gas emissions as are produced by 21 percent of the U.S.’s 417 coal-fired power plants.
If the U.S. moved aggressively to start harnessing the solar power it receives daily, it could generate enough clean energy to meet the country’s needs many times over, according to a new report from Environment Florida.
The report, “On the Rise; Solar Thermal Power and the Fight Against Global Warming,” touts the multiple benefits of solar thermal power that the U.S. has barely begun to tap. One, it’s a clean source of energy that could replace other power sources that generate greenhouse gases and worsen climate change. Two, by storing thermal energy, it can generate electricity even when the sun isn’t shining. And ,three, it’s wildly abundant in the U.S., offering way more clean energy than we currently use on a daily basis.
Green Light New Orleans Recently reached a milestone: 60,000 compact fluorescent bulbs installed for free in local homes since October 2006. The headline-making 60,000th CFL was installed earlier this month at the Jeannette Street home of Irene Green.
Established in 2006 after the devastation of Hurricane Katrina, Green Light New Orleans is the brainchild of Swiss-born musician Andi Hoffmann, who’s now a resident of the Big Easy. Hoffman started the program first as a way to offset the greenhouse gas pollution he and his band b-goes generated during their tours to Europe. It’s since taken on a greater goal: to reduce New Orleanians’ energy costs and help fight climate change.
Can a company that manufactures copy machines, and sells more paper than any other single brand, really walk the talk on sustainable business practices?
That question framed my response to an offer to talk with Patty Calkins, Vice President of Environment, Health and Safety at Xerox Corp. After all, don’t copy machines “[consume] vast amounts of water, paper, and energy…?” I’ve seen numerous press releases on environmental issues from the company whose name is now synonymous with “photocopying,” but I was still skeptical: isn’t this still a business model built on heavy inputs of energy and paper?
Patty and I talked on the phone last Wednesday (April 9), and, as in other situations, my reservations were addressed directly and concretely. I had forwarded a version of the above question prior to our talk, so she was ready for me. Among the company initiatives she detailed for me:
Human exhalations are contributing to the ongoing increase in atmospheric carbon dioxide levels that are driving climate change, according to a new study released today from the University of Northwest Florida (UNWF).
The four-year-long study by atmospheric scientist Lawrence Meany concluded that human respiration and conversation could be responsible for up to 12 percent of the greenhouse gases entering the atmosphere every year. And, Meany discovered, that percentage appears to be growing.
Renowned climate scientist James Lovelock says humanity has now passed the point of no return when it comes to climate change. There’s nothing we can do to stop the climate train, he believes, so we should start getting ready to adapt to life on a hotter, more forbidding planet.
Not one to ever stay out of the news for one reason or another, Wal-Mart this week unveiled what it calls its most energy-efficient U.S. store yet: the HE.5 prototype.
The store, located in Las Vegas, is said to use up to 45 percent less energy than your basic Supercenter. It’s also designed specifically for the Southwest’s typical climate conditions.

Yesterday the New York Times’ Dot Earth blog put up an excited post about a Los Alamos National Laboratory plan to convert CO2 into truly greenhouse-neutral synthetic gasoline and ethanol via “an electrochemical process.” Two hours later the blog had to temper its enthusiasm, having noticed that it would take huge amounts of energy, probably from nuclear power, to make it work.
This sort of thoughtless enthusiasm is way too common. At least no investors lost money this time, or, rather, yet.
I don’t want to insult anyone, but I think the real problem is that people don’t understand the chemistry — not even at a freshman level — that’s involved in thinking about what it would take to turn CO2 into fuel on an industrial scale.
