Halliburton apparently tell lies at their website

Halliburton say at their website they really care about community relations. An issue that will affect all the communities where they invest would be global warming I'd guess, and the impact of oil dependency on global warming seems pretty much established science, so I looked up "global warming" in the search engine at their website to see what innovations they are bringing to bear to help the problem - but they didn't have a single entry. Hmm.. they had 176 for "oil" (surprised it was so few actually). So then I looked up their energy page to see what they had to say about alternative energies supplies - but they only seem to operate in the field of oil and gas extraction. Don't they even have a picture of a happy kangaroo like Chevron - or a fig leaf maybe?
