Green Options

President Obama has just signed an Executive Order that compels the largest consumer of energy in the US economy to invest in energy efficiency improvements to get to huge reductions in energy use by 2020.

Every Federal agency must measure, manage, and reduce greenhouse gas emissions to meet specific targets by 2020. They have just 90 days to lay out a plan to meet these targets:

1. Use 30% less gas by 2020. Federal agencies buy 750,000 new vehicles every year. In normal times that’s almost 1 in every 17 vehicles sold per year. This Executive Order creates a rock-solid certain market for fuel-efficient vehicles every year from now till 2020.

2. Design all new government buildings from 2020 to be net-zero energy. Wow! Jimmy Carter might have gotten just a few solar panels up on merely one government building; The White House. But this means every new government building goes solar to cut fossil energy use to zero.

And they won’t just want solar power. They’ll need efficient windows, geothermal ground heat exchanges, efficient air conditioning, solar hot water heating, radiant flooring, tankless water heaters, great insulation… (and all this will take retrained architects, and doing that will take new classes, and those will need new instructors, who’ll need new suits…this is going to be a green jobs boom!)

When WalMart finally unveiled their new Sustainability Index, I found the 15 questions a bit underwhelming. Especially, after all the press and fuss (you can download the questions from the WalMart web site).

For example, the first question, “Have you measured your corporate greenhouse gas emissions?” is so simplistic, that a yes answer could mean many things. Scope 1? Scope 2? Have they taken on the challenge of addressing the full supply chain?

GreenBiz.com offers some advice for getting the most out of the questions, if you are a Walmart supplier that is just beginning to think about environmental issues.

Got a collection of reusable shopping bags? Same here… but I’ll freely admit that sometimes I forget them, or decide to stop to pick things up when I don’t have them with me. You’re probably in the same boat: despite your best efforts to reduce your use of plastic shopping bags, you’ve still got a stash of them somewhere…

So what do you do with them? You definitely want to keep them out of the waste stream, so obvious uses, like lining trash cans or otherwise using them for waste disposal, aren’t the best choices. You’ve got other options, though… and, as you’ll see, your choices for responsible disposal are expanding.

How to Reuse Plastic Bags

If you’re not going to pick up the dog poop with them, or line the bathroom trash can, how can you put those plastic bags to (re)use? Turns out there are quite a few upcycling options…

• Make a sweater… or a scarf: You crafty types can turn those bags into yarn… and then knit, crochet or weave with it.
• Fuse them into “cloth”: Got an iron and some old paper? You can make cloth-like crafting material out of your bags, also.
• Protect and store food: Making a trip to the farmer’s market? Put a few of those plastic bags inside your reusable one to separate and protect the food you buy. You can also use them for storage once you get your produce and baked goods home.

SAB Ltd, is funding water saving projects to compensate for its potential water consumption of 14 billion litres a year in South Africa. WWF (World Wildlife Fund) is facilitating the “water neutrality” process with a South African Government Project to ensure that this is not just a multinational greenwashing.

SAB Ltd is the South African subsidiary of SABMiller which is the second largest brewery in the world .

Water Neutrality

In October 2008, Dr Deon Nel, Head of the WWF Sanlam Living Waters Partnership explained

“The concept of water neutrality, based on its carbon equivalent, has been used loosely over the past years; however, until now no-one has been able to quantitatively justify these claims. We believe that our scheme is the first in the world that allows participants to truly claim to be water neutral.”

Participants will replenish water supplies, by investing in projects that quantitatively supplement water supplies equal to their water usage.

Note: Water neutrality has taken on a form in certain areas that is significantly different to the process introduced here by WWF.

Nasa scientists have told government’s that a simple cut in worldwide emissions of soot could lead to a dramatic reduction in the effects of global warming, as well as preventing hundreds of thousands of deaths from air pollution.

Soot contains black carbon, thought to be the second largest cause of global warming after carbon dioxide. Whilst airborne, it it spread around the globe by wind, heating the atmosphere by absorbing and releasing warmth from the sun’s rays. When it falls to the surface it also darkens snow and ice in polar regions or high mountain ranges, further reducing the Earth’s ability to reflect solar radiation.

Cutting soot emissions has a virtually instantaneous effect since it disappears rapidly from the earth’s atmosphere, unlike CO2, which can linger for hundreds of years.

The Environmental Protection Agency (EPA) has announced that, as a result of its enforcement actions, U.S. companies will spend a record-breaking $11.8 billion on pollution control and projects to clean up the environment this year.

A new report by the Massachusetts Institute of Technology (MIT) Energy Initiative predicts that a 30-50% reduction in fuel consumption is possible in the US over the next 25-30 years. Initially, this will be achieved through improved gasoline and diesel engines and transmissions, gasoline hybrids and reductions in vehicle weight and drag. In the longer term, the study concludes that plug-in hybrids and, later, hydrogen fuel cells may begin to have a significant impact on fuel use and emissions.

The report, ‘On the Road in 2035: Reducing Transportation’s Petroleum Consumption and GHG Emissions,’ summarizes the results of an MIT research project that assessed the technology of vehicles and fuels that could be developed and commercialized during the next 25 years.

The research team assessed the effect of new vehicle and fuel technologies on the performance, cost and lifecycle emissions of individual vehicles. It then assessed the effects on the total on-the-road fleet of introducing these technologies using “plausible assumptions about how rapidly they could be developed, manufactured and sold to buyers to replace existing vehicles and fuels or to add to the existing fleet.”

Sure there's cooked corn and corn chips and corn flakes and cornbread and the myriad other varieties found in the average American market. And, with the arrival of summer, there is now corn-on-the-cob (though here in the upper midwest: the sweet corn at the local supermarket right now is trucked in from Florida, not locally grown).

But in addition
