'Flying' by the Seat of Their Pants

Lots of companies seem to be attempting to cash in by 'greenwashing' their products or activities (in spite of the fact that, in most countries, the general public, who buy things, appear to be more concerned about environmental issues than their political representatives). It is interesting to note that the UK Advertising Standards Agency has seen fit to ban the advertising of 5 of their number (https://www.theguardian.com/technology/2020/feb/09/the-five-ads-banned-for-greenwashing). Ryanair has been criticised for advertising describing itself as the 'greenest' airline in Europe. It is difficult for any provider of air travel (especially one with lots of short haul flights) to claim that it is doing anything other than greatly increasing 'greenhouse' gas emissions (I am not convinced by claims by aircraft manufacturers, airlines and airport operatives that technological advances will transform the situation). BMW was also taken to task for its claim that its new electric car produces 'zero emissions' (this is neither true in the construction nor the running of vehicles). Producers of immersion heaters and biodegradable dog waste bags were also found to be making claims about their products that constituted greenwashing. Finally, Shell, a hydrocarbons company that has made many recent attempts to convince people of its desire to 'go green' was held, largely by virtue of its involvement in the extraction of oils from Canadian tar sands, to still be, contra its advertising, a net polluter.
