I think the article is a bit disingenuous. It's actually finding the carbon footprint of animated banner ads (since the only Flash content on the page right now seems to be a lone video player that does not autoplay). A more interesting test would be a comparison between these Flash ads and their equivalent HTML5/Canvas ads.
