This is exactly the problem in the USA. The moment anyone suggests government mandate anything for the collective good, there are cries of authoritarianism - and the idea is stillborn.
You're wrong about Ameristan. We (not me) love authoritarian
solutions to problems. I just prefer a different approach, & in
this case it's a practical one.
Private enterprise on its own is not capable of looking at the long term future of humanity and the planet, and then making decisions that require large short term costs, in exchange for ultimate gains by people not yet born, who won't be buying their products! It's classic example of market failure. And that is where government has a duty to step in. That is what it is for.
The point of my suggestion is that long term
goals can be incentivized by tax policy.
You can get so far with tax, I grant you, but the trouble is governments become wedded to the tax income and companies start gaming the system instead of getting on with the changes. I see no reason to rule out legislation. For example it is legislation that California has used, repeatedly, to reduce pollution from motor fuel (the business I was in when I did a brief spell in Houston).
If you're worried about gaming the system, that is a problem
that can afflict the authoritarian approach too. The questions
are which will work best, & which is politically palatable.
The cycle goes like this:
1) California mandates a new fuel or vehicle standard from a certain date.
2) Everyone howls that it is impossible, will put everyone out of work, huge snakes, many of them millions of miles long, will roam freely through the countryside, etc., etc.
3) The date arrives - and everyone is able, somehow, through gritted teeth, to comply, having spent the money to do so.
4) The rest of the USA slipstreams behind California and eventually adopts the same standards, because - hey presto! - now everyone can meet them.
That approach doesn't always work, eg, mandating anti-lock
braking on big trucks in the 70s. The technology didn't arrive
(fully), & government had to back off.
This seems to all boil down to a difference in approaches, ie,
incentives vs commands. I prefer the former.
Consider also that we need increased tax revenue. it would
be better to get it from activity we want to discourage than
from things that should be encouraged, eg, earning income.
Why am I getting solar air heating & photovoltaics?
Financial incentives.
There's no subsidy for air heating that I know of,
but utility costs make the investment worthwhile.
Photovoltaics will get me a 26% subsidy this year,
which tipped the scale towards acceptable rate
of financial return.
To have mandated solar panels on homes would've
been too complex & too impractical to impose by
governmental fiat. But with the incentives, solar
companies are doing much business here...with the
flexibility & customization suited to each application.
Regulation has been useful in requiring DTE (the
utility) to credit us for power supplied to their grid.
This is simple & minimal regulation which enables
the subsidies to work better.
