HBO told the show runners(D&D) they could take as long as they wanted to finish the series. D&D had just landed jobs at the helm of a new Star Wars trilogy so they were eager to wrap up Thrones and start raking in that Disney cash. They made the last season shorter than other seasons, it sucked and they ended up losing the Star Wars deal.

IIRC the study that the “X% of companies are responsible for X% emissions” is somewhat misleading. For example they use the combined output of everyone’s car exhaust and attribute that to the major oil companies since they provide the gas. Not saying that large corporations and the wealthy in general contributing to climate change exponentially more than the average person, but its misleading to say that as an individual it doesn’t matter if we try to use less energy.
