	Why we choose 'Green' products The case for preferring those products that have the least environmental impacts is necessary and compelling.
	Measuring environmental impacts The science of environmental impact analysis is still developing. There's a lot we know, but, equally there's much we don't. The challenge is to move forward with what we've got.
	The PASS system: how GreenSpec selects products There are variety of methodologies associated with identifying green products. GreenSpec uses the PASS system which combines evidence with expert knowledge.
	Manufacturers' documentation: the information we use to assess products   In the detailed assessment of a product, the GreenSpec review team look to a wide and comprehensive selection of data, documents and certificates in order to be assured that a product is well-supported with evidence.
	The Rules of Evidence Long established in court rooms are rules that govern the way facts are used to support claims. The rules are easily adaptable to  help us analyse claims made of products and materials.
