Rel-Ecolabel is a simple, open, format for indicating ecolabelled items which is embedable in HTML or XHTML, Atom, RSS, and arbitrary XML. Specification 2008-05-12
By adding rel="ecolabel" to a hyperlink, a page indicates that the destination of that hyperlink is the ecolabel for an ecolabelled item listed on the current page. E.g. with the following hyperlink:
<a href="http://ecolabelling.org/ecolabel/ecologo/" rel="ecolabel">ecologo</a>
NOTE: in the highlighted portion - is this where we would put an ecolabel code or readable URL for ecolabelling.org entry?
the author indicates that the product, company, or services has obtained an "ecologo" certification.

It seems that it might work well with being linked to an hproduct / hCard - to identify a manufacturer - I've yet to explore hproduct in detail.
I don't know that pointing the URL of the ecolabel directly to www.ecolabelling.com would work.
If I ran a product site with ecolabelled products, I would want to point to either a source of information on the label internally within the site, or have it point to a list of all data tagged with similar ecolables.
<a href="http://myproductsite.org/ecolabel/ecologo/" rel="license">ecologo</a>
The destination would then show all ecologo tagged products within the catalogue of myproductsite.org
maybe microformat parsing tools could be created to send users or pull information from www.ecolabelling.org site as a source of authoritative info and background on the label.
rel-tag as an example can point to an internal site structure using a taxonomy but can also use microformat tools to extend data searches to sites like technorati.
Multiple such rel="ecolabel" hyperlinks indicate that multiple items on the page are available under any of the referred licenses. E.g. the following hyperlinks could be used to declare that a page is available under either an ecologo or a certified carbon free ecolabel:
<a href="http://ecolabelling.org/ecolabel/ecologo/" rel="ecolabel">ecologo</a> <a href="http://ecolabelling.org/ecolabel/certified-carbonfree/" rel="ecolabel">certified-carbon-free</a>
