Australia on fire

At the end of the day movement towards renewables and a greener planet
will also be largely a private initiative. Governments are intrinsically involved
but also often technologically out of touch, slow to respond and generally
have short term planning objectives anyway - so there is plenty to discuss
without them.

Government regulation can and does drive technological advance.

Case in point: There were two companies in Germany refining white pigment from naturally occurring titanium dioxide, one up north near the North Sea, the other further south on the banks of the Rhine.
At the time the process created a large amount of sulphuric acid as waste which the company up north dumped in the North Sea by tanker while the southern one pumped it into the Rhine. Both did that legally at the time.
The Rhine was facing ecological collapse due to all the crap put into it so the government simply banned it despite being lobbied by the polluter claiming a ban would cause them to face bankruptcy with the associated loss of jobs.
The ban went ahead and lo and behold within 6 months the company by the Rhine had developed a process which did not produce any waste acid at all.
