Good points. An additional concern is that this does not address legacy fossil energy production and legacy CO2 already in the air. There is no incentive to decarbonize fossil energy other than to kill fossil energy, and this can't and won't happen overnight. By their own admission the tax they envision addresses <50% of emissions over the coming decades. So what is the plan for the other half, esp without any additional incentives to mitigate point and non-point sources and air. E.g., have we just wasted $20B on CCS R&D?Greg

I side with Doug McMartin on the parallel geo thead; there is a real risk that non-fossil cannot substitute for fossil energy fast enough globally under the best of economic incentives. China will not abandon their 100s of new coal plants in the next 20 years. Replacement of fossil with PV and wind assumes that we have solved the energy storage problem. If we don't or can't, then what is Plan B? So we need to also invest in decarbonating fossil energy and air if we are serious about stabilizing and then lowering air CO2 and global temps. Maybe the $40/tonne tax will be enough to incentivize the search for $35/tonne CCS and CDR.G
Making the assumption that
fossil fuel power plants will make progress in the cleansing, washing and removing
exhaust pollutants (reducing SOx & NOx emissions; eliminating heavy metals,
soot and particulate matter…), and thus in the future just emit CO2; then there
is no reason
for the coal mining industry or to the oil industry to fear a
carbon tax or to stop building new fossil fuel power plants.
A new paper by Oeste et al., suggests that just by doubling current tropospheric Iron emissions can stop global warming. www.earth-syst-dynam.net/8/1/2017/esd-8-1-2017.pdf
The iron has not to be emitted in the stratosphere.
Best wishes,
Renaud de Richter

I agree with that, but we do still need more proactive initiatives, on multiple fronts, sooner!Aryt

I think the incentives supporting fossil fuels are not as insuperable in the longer-term as is often assumed. If oil and gas weren't currently so cheap from a supply glut - say, < $80/barrel - then PV solar would already be cost competitive for electricity production. And on the current cost decline curves, PV solar plus storage beats all fossil fuels across the board on LCOE without subsidies by 2025 in the majority of global geographies. That's with fossil fuel prices running fairly close to the cost of production (it isn't clear yet what the price floor is to sustain fracking, but it certainly isn't $20/barrel).This is only my personal opinion of course, but think PV solar WILL kill fossil fuels on economics alone almost everywhere by 2030.
