You might want to take a look at the About page, and their Disclaimer at the bottom:

That it looks like a real paper is part of the joke, it's pointing out the absurdity of companies trying to continue to emit carbon as long as they can use carbon credits, which doesn't address the root problem. The joke of the paper is essentially; what if a researcher who was paid by a mega corp to find a 'solution' (which the corp would want to be greenwashing), actually naively proposed a genuine solution using corporate friendly concepts and language.
