Greenwash Watch: Sherwin Williams GreenSure Label

We learn from Inhabitat that Sherwin-Williams has introduced a new line of paints, and has invented a new label, GreenSure, to go with it. They list a whole pile of standards and requirements that their paints must meet to get GreenSure; no doubt they will mean something to chemists. But what does it mean to the public? Not a whole lot. But let's look at one of the standards, perhaps the most important for paints, the Volatile Organic Compounds or VOCs. As is shown above, Sherwin Williams' standard for VOCs is 50 grams per litre.

Now I don't know it that is high or low, but I do know that there is an independent third party standard, GreenGuard, that tests products for VOCs and gives its label to products with VOCs lower than .5 milligrams per cubic metre. For some unknown reason Sherwin Williams uses a different metric unit and there are a lot of zeros involved.

I did not believe my results so I used an online calculator and it confirmed that 50 g/l is 50 Million milligrams per cubic metre, or a hundred million times as high as Greenguard permits. Now a hundred million times almost nothing can still be almost nothing, but that is fifty kilograms per cubic metre; if paint has roughly the same density as water then it is up to five percent pure VOCs.

When you look at the four paints that have GreenSure certification, two are GreenGuard and two are not. The Greenguard ones have zero VOCs; the two that do not have GreenGuard certification have VOCs right up there near the GreenSure limit.

No doubt Sherwin Williams had good reasons for putting the VOCs in; people demand a certain level of performance, coverage, speed of drying, they probably couldn't get the paint to perform they way they wanted with no VOCs

But that doesn't mean that they can call it green. Just because you don't want to comply with the established third party standard doesn't mean that the customer has to accept your own dubious invention of one.

Unless my mathematics are off by about six zeros, this product is greenwashes in a number of ways:

-it isn't third party verified.
-it is rated against a meaningless standard that is incomprehensible to the public.
-it is designed to confuse, listing "chemical component restrictions" like lead and mercury that haven't been allowed in paint for years.
-it creates a pretty "GreenSure" graphic to give consumers a false confidence.
-it blows past the standard that anyone else in the industry considers the green standard.

Really, lets cover the earth with real science and real standards, not slick marketing. As Andrew Pace of Degree of Green said so well in Inhabitat:

Their program was internally created by their own marketing people, so there is no third party verification of the claims. This is akin to Phillip Morris saying that nicotine is not addictive.”

Or as we might say, inside-job green labels aren't worth the recycled paper they are printed on.

Bookmarked.. thank you. You know your topic very well. I also found interesting info on http://www.rapidmediafire.com

Well my comment is simple. I understand your math conversion, but that conversion tells you the how many milligrams it would take to fill a cubic meter at the same ratio as a litre of paint that has approximately 43 grams per litre of voc content. The conversion is not for showing how the liquid voc's are emitted into the air.

I know some of you might say it is unsafe to add some solvents to different liquid chemicals

I just need a list of liquid chemicals to test for my science fair project. I know some of you might say it is unsafe to add some solvents to different liquid chemicals, but for now, I just need a good list of liquid chemicals to add it. I'll do my research on these chemicals and see if it will be safe or not.

Numbers mean a lot in business. Like they talk about the thickness of plastic bags in supermarkets. Scientists like to brag about accuracy and precision.
