The Paris (COP 21) commitments evidence a will to act, and France has been in the forefront of government action. But early moves toward higher carbon prices have caused civil unrest, even in France, from those most affected.
“…Decarbonisation doesn’t come without consequences for the average member of the public – and those impacted by those consequences can easily feel like they are being sacrificed on the altar of environmentalism.”E3G Senior Policy Adviser Camilla Born
“The government talks about the end of the world. We are worried about the end of this month.”Gilet Jaunes slogan cited in https://www.project-syndicate.org/commentary/yellow-vests-green-new-deal-by-joseph-e-stiglitz-2019-01
Americans similarly believe in man-made climate change, but they are not willing to pay to stop it: 70 percent of Americans say they wouldn’t pay $10 every month to help cool the warming planet. https://www.theatlantic.com/science/archive/2019/01/do-most-americans-believe-climate-change-polls-say-yes/580957#
The UN Principles for Responsible Investment believes, along with Paul Gilding, that there will be an “Inevitable Policy Response” to climate change. At some ‘tipping point’ within the next 5 years, governments will start to act. But what sectors will they target and why? Paul Gilding and Jorgen Randers’ ‘One Degree War Plan’ is an example policy response based upon a 50% reduction in carbon emissions spread evenly across the 7 major emitting sectors: Energy, Forestry, Agriculture, Waste, Buildings, Industry, Transport https://paulgilding.files.wordpress.com/2015/01/one-degree-war-plan-emerald-version.pdf. Gilding and Randers give no reason for this allocation of the reduction work, other than simplicity.
The UN PRI notes that policymakers have a variety of options available to achieve reductions in emissions, and have given little indication about how they will choose among those options: “Policies to reduce emissions differ in their impact on financial markets, even when the broad technology pathway might look similar.” The UN PRI’s intended research program will look at the relative ‘efficiency’ of various ways of reducing emissions. It is very focused on the uncertainties around the degree of global co-operation and the potential for broad trade disruption if nations protect their economies against imports from countries with lower carbon prices. https://www.unpri.org/climate-change/an-inevitable-policy-response-to-climate-change-when-what-and-how/3580.article
So far, I have not found any attempt to rank emission reduction options according to the social disruption they involve. Let me know if you find any such work. I will be looking further and reporting back on what I find…
