I don't think any of that matters. What she is doing, which is about shaming us all for not acting more urgently, is about as much as you could expect of someone her age (and in fact it is effective as a moral argument precisely BECAUSE of her age). I think it's all you can ask. Now, WTF are you doing about climate change that gives you moral grounds to criticise what she is doing?
I won't address the other points (some of which are a misrepresentation) as I've stated my previous post would be my last. However:
My company has just invested £120k on Tesla Model 3's to replace petrol/diesal cars. We'll be investing this every year until we have a full fleet.
My company has invested £750k over the last decade in biomass heating instead of sending what was previously junk to landfill.
We're looking at installing £250k of solar panels over the next 5 years, subject to cash flow of course.
We've invested £300k in new HGV vehicles that are up to 30% more efficient.
We now recycle all of our 25 tonnes of plastic and cardboard waste; all of which went to landfill a decade ago (we actually make several grand doing so and save several grand in skips).
We've invested £50k in the installation of LED lighting and will continue to do so until every light fixture is LED.
We've invested in technologies that mean less travel for all of our reps, reducing miles traveled by a third in many cases.
We've implemented a cycle scheme whereby the company will buy bikes for staff who ride to work instead of driving (very low take up unfortunately).
We have a focus now on employing staff in the local area where two members of staff are of similar caliber.
We've changed packaging solutions from plastic to timber where practical, saving hundreds of kg of plastic usage per year.
We've invested £320k in the last 2 years on new CNC machines that are far more efficient, meaning you can achieve roughly 40% more output using the same quantity of electricity.
We've invested £20k and plan to invest much more in the testing of a graphite compound to replace plastic in a key component that our industry uses. It's very early days but if successful this could reduce plastic in every commercial building in the UK (although regulations are against us as it stands).
We now include a "maximum quantity of deliveries" on all our quotations to prevent customers from requesting dozens of deliveries, where half as many will suffice. This has nudged our customers into reducing traveled miles by the thousands.
I myself am replacing my Diesal car with a Tesla in the next year.
I now only eat meat bought from local butchers, which source their meat a stone's throw away from my house.
I am in the process of buying a lawn mowing robot so that I can get rid of my petrol ride on mower which is far less efficient.
