I don't remember anyone giving much of a shit about emissions in the 1980s, but I was young at the time. One thing I never did quite understand was how we let the coal mines get in such a state apparently they'd be exceedingly difficult to get going again because they're flooded etc...Maybe it wasn't feasible or economic.
Britain has always been world-leading in giving zero fecks about energy security or any other important service, eg selling water, electricity, gas, nuclear supply, ports and airports to any overseas bidder, and now chip companies too.
