Comparisons of life-cycle greenhouse gas emissions
Hi. I made several change to the page about Comparisons of life-cycle greenhouse gas emissions, feel free to check it out. It might interest you since you edited this page recently. AlexH555 (talk) 03:17, 31 May 2010 (UTC)

Thank you for your work. I agree with you, the subject is unnecessarily restrictive. More modification needs to be done, help welcome. AlexH555 (talk) 18:37, 1 June 2010 (UTC)
