Hi, I do not believe that adding the external link (www.click4carbon.com) is considered spamming. Click 4 Carbon is relevant to the subject in question (http://en.wikipedia.org/wiki/Carbon_footprint).
Click 4 Carbon contains a wealth of information, regular news and blog updates, facts pages that are all Carbon Footprint related. Having checked the wikpedia policies.
1) There is nothing wrong with adding one or more useful content-relevant links to an article. 2) Wikipedia articles may include links to Web pages outside Wikipedia. Such pages could contain further research that is accurate and on-topic.
I look forward to hearing from you.

Please stop adding inappropriate external links to Wikipedia. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Since Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you will be blocked from editing Wikipedia.
