Claims / C-WSV69QM3D8
Conjecture
Cheaper-and-cleaner has decarbonised; pledges have not.
The claim
Emissions have fallen where a cleaner option was also cheaper or better, not where targets were set: efficiency, gas, nuclear and hydro did the decarbonising, while global emissions rose about 65% from 1989 to 2019.
Argument role: mechanism. Synergy with the abundance thesis: Smil, a sceptic of fast transitions, finds that what did decarbonise came as by-products of cheaper or better technology (chunks 450-451), while conferences left emissions up ~65% (chunk 471; chunk 473 gives CO2 +65% 1992-2019, consistent). That is the track record behind making clean options the cheapest ones (C-RJS8F3VGS7).

And yet, so far, the only effective, substantial moves towards decarbonisation have not come from any determined, deliberate, targeted policies.
groundsSource document
Higher conversion efficiencies, more nuclear and hydro generation, less wasteful processing and manufacturing procedures
groundsSource document
Between 1989 and 2019, we increased global anthropogenic greenhouse gas emissions by about 65%.
