Chemical Structure of BPA

You try and choose foods that are as free as possible of harmful chemicals such as pesticides. But if you consume canned soups, beans and soft drinks, organic or not, you also may be swallowing residues of a controversial chemical called bisphenol A (BPA) that can leak out of the can linings into your food. Nearly all can liners contain BPA, says Geoff Cullen, director of government relations at the Can Manufacturers Institute in the United States. BPA has also been found to migrate, under some conditions, from polycarbonate plastic water bottles.

Tidal Energy: “Not for us” says power company

February 6th, 2009
Coat of arms of British Columbia

By Paul Crossley

Green is everywhere these days.  Even in tough economic times, governments are speaking about ‘green jobs,’ the ‘green economy’ and such noble concepts.

Talk like this can give us hope that these harsh economic days, months and years to come will see the birth of new industries focussed on giving us what we need albeit in a greener overall package.

So, in a Canadian province ostensibly on the forefront of everything green it seems incredible that the province’s power company has turned down green power.  British Columbia’s Crown Corporation, BC Hydro says that it now requires that any new technology which would provide power to the grid must have at least three years of ‘proven commercial reliability’.  In short, BC Hydro is saying, “Sell your power to someone else, and after you’ve done that for three years, then you can come and talk to us.” Read more…

Leadership in Energy and Environmental Design (LEED)

December 22nd, 2008

From Fine HomeBuilding - Energy Smart Homes

Compact fluorescent light bulb

Even among buyers inclined toward green construction, the biggest hurdle green builders face is that most homebuyers don’t have the knowledge to evaluate competing claims of greenness.  And in the building industry, a lot of people are claiming to be green.  For the consumer, it can be a real challenge to pick legitimate green products and services from those that have been “greenwashed.”  This is where LEED comes in.

LEED (Leadership in Energy and Environmental Design) is a system developed by the U.S. Green Building Council (USGBC; www.usgbc.org) to encourage the consatruction of energy- and resource-efficient buildings that are healthy to live in. In the LEED for Homes (LEED-H) program, participating houses are awarded points based on materials, construction methods, and energy efficiency.  The USGBC awards a LEED rating of certified, silver, gold, or platinum based on the number of points a house accumulates in the 136-point system.  The point total for each grade listed below is for an average-size house.  The point threshold in each rating category is lowered for smaller-than-average houses and raised for larger-than-average houses.

  • Certified, 45 Points
  • Silver, 60 Points
  • Gold, 75 Points
  • Platinum, 90 Points

The strength of the LEED-H program is that the rating is done by a third party.  All of the material selection and construction techniques are documented, and the home’s energy performance is tested.  A homebuyer doesn’t have to take the real-estate agent’s or the builder’s word that ccertain construction methods were used.

LEED-H has its critics, but devising a system that provides a comprehensive evaluation of the home-building process from design phase through homeowner posession - one that uses a consistent, meaningful grading scale regardless of locale-is an ambitious undertaking.

LEED-H now grades on a 136 point scale.  Points are offered in eight categories for adopting specific building practices and for using certain materials or products.  All homes in the program must adopt 18 mandatory measures.  In addition, 16 points must be achieved to meet minimum requirements in four of the categories.  Architects or builders are free to choose how they want to acquire additional points depending on variables such as site, climate, house design, and budget.  Below is a breakdown of the LEED categories, the number of points available in each category, and the goals of each category.

Innovation & Design: 11 Points

Integrate knowledge of all the trades in the design process, plan to make the most durable house possible, and orient the house for solar design.

Location & Linkages: 10 Points

Choose a socially and environmentally responsible site.

Sustainable Sites: 22 Points

Minimize the impact of constructin and the house on the site.

Water Efficiency: 15 Points

Conserve water indoors and outdoors.

Energy & Atmosphere: 38 Points

Build a well-insulated and tight building envelope with efficient heating and cooling systems.

Materials & Resources: 16 Points

Reduce material waste during construction, and use green products.

Indoor Environmental Quality: 21 Points

Use appliances, installation methods, and ventilation measures to improve indoor air-quality.

Awareness & Education: 3 Points

Compile a homeowner’s manual covering the operation and maintenance of the house.

Cloth Diapers vs Disposable: More than an Environmental Debate

December 17th, 2008

By Paul Crossley

Cloth Diapers vs Disposable...a 'rashional' debate

Cloth Diapers vs Disposable...a 'rashional' debate

There tend to be two distinct sides to the Cloth Diapers versus Disposable Diapers debate: either you’re ‘for’ cloth and against disposable or the opposite.  You may also have the reasons lined up in your mind with regard to precisely why you’re in one camp or the other.

Common reasons to be ‘pro’ cloth include such notions as, reducing landfill, the bacteria and viruses created from human excrement in landfills, trees and plastics used to create disposables and so on.  The ‘pro’ disposable segment will speak to pesticide use in growing cotton (though organic cloth diapers are now available), pollution through harvesting and transporting cotton (though producing and transporting disposables also causes pollution) and to human waste in the local water supply through laundering (though this water waste goes to the same place as the water waste in your toilet: the sewage system.

This article will look at the pros and cons of the ecological debate and introduce an additional element over and above the well-being of the Earth: our own health. Read more…

Another Inconvenient Truth - About Carbon Offsets

December 16th, 2008

Reprinted from BusinessWeek, March 2007

Carbon Emissions & Offsets

Carbon Emissions & Offsets

The organizers of the Academy Awards declare all their celebrity presenters to be “carbon-neutral.” Vail Resorts Inc. in Colorado boasts that its chairlifts and lodges are “100% powered by wind.” Seattle’s municipal utility claims that its net contribution to global warming is zero.

A growing number of organizations, corporations, cities, and individuals are seeking to protect the climate—or at least claim bragging rights for protecting the climate. Rather than take the arduous step of significantly cutting their own emissions of carbon dioxide, many in the ranks of the environmentally concerned are paying to have someone else curtail air pollution or develop “renewable” energy sources. Carbon offsets, as the most common variety of these deals is known, have become one of the most widely promoted products marketed to cheque-book environmentalists. Read more…

“Business Reasons” are why you can’t have it.

December 2nd, 2008

By Paul Crossley

I give you exhibit ‘A’ :

Ford ECOnetic
Ford Fiesta ECOnetic

This attractive, economical car is a 2009 Ford.  This sporty new design seats five, offers a GPS navigation system, and will give you an incredible 65 miles per gallon (about 3.7L/100km).

A diesel powerplant provides the stunning fuel economy, but therein lies the rub:  Due to the little car’s use of diesel, it will not be made available to North American users.  “We know it’s an awesome vehicle,” says Ford America President Mark Fields. “But there are business reasons why we can’t sell it in the U.S.”  The ‘business reason’ is used here as code-language for saying, “because it runs on diesel.”

Diesel fuel is regarded as a relatively old technology while North Americans flock to the various hybrid technologies, forsaking all others.

This Fiesta has been tweaked to minimize fuel consumption and CO2 emissions. In this case the car is equipped with a 1.6L diesel and the usual mix of closing off openings in the front to reduce the drag. A pair of small air deflectors on the trailing edge of the wheel wells helps to control airflow coming off the back of the car. Revised engine calibrations, a taller final drive ratio and low rolling resistance tires yield a combined mileage rating of 65.3 mpg (US) on the EU test cycle. Carbon dioxide emissions are measured at 98 g/km.

This and similar stances are a prime example of North American auto manufacturers’ ecomentality. There is a rumour that the Fiesta ECOnetic, or a variant of it, may be available in North America sometime in 2010…only time will tell.

Would you like to see more diesel in North America?

Greenpeace’s Guide to Greener Electronics shows companies are stalling on real climate action

November 24th, 2008

Since the first edition of the Greener Electronics Guide in August 2006, there have been gradual improvements on toxic and e-waste issues, but only a minority of companies are really leading on energy and climate change. Motorola, Microsoft, Dell, Apple, Lenovo, Samsung, Nintendo and LG Electronics are notably lagging behind, with no plans to cut absolute emissions from their own operations and no support for the targets and timelines needed to avoid catastrophic climate change.

These huge companies could make a big difference by doing their part to avoid a climate crisis and asking their governments to do the same.

“Sadly it appears that the consumer electronics industry is much better at rhetoric than facing the reality that absolute emission cuts are urgently needed,” said Greenpeace International Climate & Energy campaigner Mel Francis. “It is disappointing that such innovative and fast-changing companies are moving so slowly, when they could be turning the regulation we need on global emissions into a golden business opportunity.”

To be green, electronics companies need to equally address energy, toxics elimination, and recycling. In the last three editions of the Guide, the climate and energy criteria have examine companies on their direct emissions, their product performance, use of renewable energy and their political support for emission cuts. The required shift to a low-carbon economy will require much smarter work practices.

With less travel and higher energy prices, companies providing smart and efficient technology solutions could leap forwards in tomorrow’s business environment. Instead, only three - Fujitsu Siemens Computers (FSC), Philips and Sharp - support the level of cuts in greenhouse gases that science requires. Only Philips and Hewlett Packard (HP) get top marks for committing to making absolute reductions in their own greenhouse gas emissions from the product manufacture and supply chain.

Many companies gain points from their products’ efficiency improvements - half of the 18 ranked brands now score over 5/10 in the guide. However, only three commit to making cuts in greenhouse gas emissions from their own operations. Most companies use little renewable energy, even though some manufacture solar panels. Nokia, which remains in pole position, sources 25% of its total electricity use from renewable energy and is committed to sourcing 50% by 2010. Other brands with points for renewable energy use are FSC, Microsoft, Toshiba, Motorola and Philips.

Some who display best practice on energy issues are still shirking their responsibilities on toxics. Philips, for example, has lobbied the European Commission against Individual Producer Responsibility. HP does not have any products free of specific hazardous substances on the market and no commitment to eliminate further problematic chemicals. Those who score well on toxic chemical criteria already have products on the market free of the worst substances, including Nokia, Sony Ericsson, Toshiba, FSC and Sharp.

Overall, the biggest moves up the ranking are Motorola, (from 15th to joint 7th), Toshiba (from 7th to 3rd) and Sharp, (up from 16th to 10th). The companies falling down the ranking are the PC brands Acer, Dell, HP and Apple. Although Apple drops a place, it has improved its total score this time because of better reporting on the carbon footprint of its products, and although not scoring any extra points, its new iPods are now free of both PVC and brominated flame retardants (BFRs).

“Greenpeace is calling for all companies to eliminate e-waste and get serious on energy issues,” said Iza Kruszewska, Greenpeace International Toxics Campaigner. “It’s not good enough to just simply comply with regulation - to be truly green, the sector must step up to the challenge and show leadership.”
