I think that one of the key points of the strikes is to emphasise the role that government and regulation has in driving change.
They can point that out while not only wearing sackcloth.
It's actually quite difficult for consumers to drive changes themselves and often changes come through fastest when driven by changes to regulations.
E.G there could be regulations requiring solar panels to be added to all new buildings. We could insist on triple glazing (for winter) and large overhang rooves (to reduce overheating in summer). There could be regulations on all new buildings about electric car charging points. There could be a push so that councils invest in green energy. My local council runs a scheme for its workers that subsidises public transport through car parking charges for people who choose to drive (excluding those with a disability obviously).
None of those require huge structural changes to society. No, they aren't going to solve the problem, but everything we can do to reduce the total warming is worthwhile.
Then let's look at the things that have already been done (but that maybe could be more drastic):
- Regulations so that all cars will have to be partially electric by (some date that I can't remember!) - these regulations have influenced manufacturers like Jaguar land rover so that (I think) by 2021 they don't intend to produce any new cars that aren't at least hybrid. Yes, they're still new cars. Yes, they aren't 100% electric, but without regulations like that the innovations in design wouldn't be happening.
- Regulations on how energy efficient appliances are - gives consumers the opportunity to make an informed choice.
- Regulation on home insulation so that we improve the energy efficiency of our housing stock over time.
- Increased availability of recycling where when I was growing up it was a novelty not a norm.
Yes, I'm typing this on a mobile phone. No I don't live in an entirely unheated house. No, I haven't composted myself for the sake of the environment.
But we don't have to be perfect to do something, and we don't have to be perfect to push for regulations to change attitudes, encourage innovation and force the issue.
(And household driving miles are now down from 10,000 a year to 3,000 - definitely still not perfect. Car is 7 years old and counting - because making new cars is terrible for the environment too. All electricity is green tariff and the gas is carbon offset. Flown once in 3 years - remaining holidays by train. Use reusable water bottles always. Most clothes second hand, and definitely no "fast fashion". Switched to bar soap from shower gel.
What's not good enough yet? Food waste is still an issue. Food miles aren't too dire. Should cut down dairy products, but beef consumption is low. Should probably switch to bar shampoo and bring your own container washing liquid and foodstuffs.)
