“…This involves two mutually reinforcing tracks along multiple phases: (1) founding a 'carbon-pricing coalition' among the most ambitious nations to implement a uniform carbon price, as either a carbon tax (Nordhaus, 2015) or emissions trading through carbon markets (Keohane et al, 2017); and (2) reorienting UN intergovernmental climate change negotiations (referred to hereafter as 'UNFCCC negotiations') to a focus on global carbon pricing. The guiding principle behind the multiphase structure is that, if one cannot reach a political goal immediately, a gradual, step-wise procedure should be tried out (Kern & Rogge, 2018;Koreh et al, 2019). The focus on carbon pricing is motivated by the fact that it is already applied in many countries (Haites, 2018), is an effective but not overly invasive instrument for emissions reduction (Best et al, 2020), can be easily compared and harmonized among countries/jurisdictions, can be gradually strengthened over time, potentially improves negotiation outcomes by moderating freeriding and fear of competitiveness losses, and automatically generates revenues, which can be used for multiple purposes, including compensation of low-income households and countries (see Table A1 in the Appendix for a more complete list of strengths and additional references).…”
