The Angry Clean Energy Guy on a virus infecting sustainability: Big Oil are deliberately poisoning what sustainability means, diluting its impact and reach, and they are doing that in plain sight, borrowing the language and applying it to terrible initiatives and companies all designed to propagate our use of harmful fossil fuels and indeed increase it, rather than decrease it, when everyone knows we need to power the world with renewables as well as pretty much phase out our use of oil, gas and coal by 2050 – to have any chance of avoiding catastrophic climate change. Winner of the week: Asset managers Sarasin, for divesting from Shell while not mincing words. Villain of the week, Cargill, named “Worst Company in the World” by NGO Mighty Earth
