They are. Because they have some measure and collected data, and some other measures totally invented. How can you state I "save CO₂ emissions" producing energy from my p.v.? How can you state up front that only CO₂ emissions count in pollution and climate change? This is not science, it's a kind of religion, to convince people formed with a kind of scientific mindset but not really inhabited to reason individually, but to accept as truth what they read. Starting from the "data collected" form certain institutions who have NO PROOF of their collection, meaning their data are not really reproducible. Just a modern variant of the old colored glass to trade gold with certain populations.
