The IPCC 1.5° C Report and the Ten-Hour Week

I read the IPCC summary for policy makers so you don’t have to. You may have heard that CO2 emissions have to fall by 45% by 2030 to avoid the possibility of overshooting 1.5°C global warming. Actually emissions must decline by 45% from 2010 levels, which are already substantially lower than 2018 levels. The strategies for reducing emissions by that amount are quite complex and depend on hundreds of governments adopting scores of policies that they have no intention of adopting.

So, burn in climate catastrophe Hell, grandchildren!

But wait! Didn’t Keynes write something long ago about the economic possibilities for our (their) grandchildren? “What can we reasonably expect the level of our economic life to be a hundred years hence?” Keynes asked that in 1930 — which just happens to be a hundred years before the IPCC 2030 target date! What about the ecological survival possibilities for our grandchildren?

I have translated the IPCC report into terms compatible with Keynes’s prognostications. Remember his prediction of a 15-hour week being “quite enough to satisfy the old Adam in most of us”? How rapidly and how steeply would we have to reduce workweeks to achieve the 45% reduction in emissions by 2030, assuming no other changes in technology (or population)?

I’ve taken quite a few short-cuts to calculate these estimates. For starters, I only look at the twenty top emitters of CO2 from 2015. I assumed that emissions reductions targets for each country should be allocated on the basis of convergence toward a uniform emissions per capita standard, which would be 45% below average emissions per capita in 2010 (for the 20 countries).

Several countries among the top twenty currently emit fewer tons per capita of carbon dioxide than the hypothetical 2030 standard. These include Brazil, India and Indonesia. Mexico is currently emitting close to what its 2030 quota would be. So my estimates are concerned only with the remaining 16 countries.

To achieve emissions reduction through hours and population limitations alone would require annual reductions in working time of between one percent for Turkey and twelve percent for Saudi Arabia. Also near the top end are the U.S., Canada and Australia at around an eleven percent per annum reduction. With considerable rounding and a generous allowance for holidays and vacations, these reductions in annual hours would indicate a workweek in 2030 of around ten hours.

In the middle range, France and the U.K. could look forward to workweeks of around 20 hours a week. China, currently the world’s largest emitter of CO2 would see its workweek cut to somewhere in the neighborhood of 25 hours per week.

Of course some of these reductions in working time could be reversed by de-industrialization — that is the substitution of less energy intensive but more labor intensive methods of production. Hours reduction could also be moderated by transition to solar and wind energy, by energy conserving technological advances and by the introduction of carbon-capture technologies, including large-scale reforestation.

This hours reduction exercise is only meant to give a simplified view of the scale of transition required. But it also alludes to an earlier transition that consolidated the central place of fossil fuels in an expanding industrial economy.

In 1847, after decades of struggle by factory workers, the U.K. parliament passed the Ten Hours Bill. In response, manufacturers turned to the high-pressure steam engines to compensate for the loss of factory working time with faster, more powerful, more fuel efficient machinery that could do more work in less time. By the end of the 1850s, steam power had decisively eclipsed water power and high-pressure steam had surpassed the low-pressure Watt steam engine.

It was not the intention of the ten-hour legislation in the mid-19th century to deliver the “coup de grâce,” to water power, as Andreas Malm termed it, but that was its effect. Might not a working time policy designed and intended to enforce a transition away from fossil fuels be worthy of serious consideration?
