Two of the biggest global challenges we face today are mitigating climate change and economic inequality. Some research suggests these goals are in conflict, based largely on the observation that a dollar spent at higher income levels is less carbon intensive than at lower income levels. We put this concern to rest. We quantify this effect in its most extreme manifestation, both within countries and between countries. We use a wide range of income elasticities of emissions (0.7–1.0) and scenarios from the Shared Socioeconomic Pathways (SSP) with the highest (SSP4) and lowest (SSP5) between-country inequality. Within countries, even with assumptions of low elasticities (0.7) and aggressive inequality reduction (Gini coefficient of 0.55 to 0.30), emissions would realistically increase by less than 8%, which would likely occur over several decades. Income convergence between countries may reduce the emissions intensity of global income growth, because the energy intensity reductions from income growth in emerging economies, such as India and China, offsets the energy increasing effect of higher growth in developing countries. Given these findings, it seems a distraction for future research to dwell on this narrow framing when there are deeper under-explored linkages and synergies between reducing income inequality and climate change, such as the effect of reducing inequality on social norms, consumption and on political mobilization around climate policy.

Using the data sets taken at center-of-mass energies above 4 GeV by the BESIII detector at the BEPCII storage ring, we search for the reaction e(+)e(-) -> gamma(ISR) X(3872) -> gamma(ISR)pi(+)pi(-) J/psi via the Initial State Radiation technique. The production of a resonance with quantum numbers J(PC) = 1(++) such as the X(3872) via single photon e(+)e(-) annihilation is forbidden, but is allowed by a next-to-leading order box diagram. We do not observe a significant signal of X(3872), and therefore give an upper limit for the electronic width times the branching fraction Gamma B-X(3872)(ee)(X(3872) -> pi(+)pi(-) J/psi) < 0.13 eVat the 90% confidence level. This measurement improves upon existing limits by a factor of 46. Using the same final state, we also measure the electronic width of the psi(3686) to be Gamma(psi)(ee)(3686) ee = 2213 +/- 18(stat) +/- 99(sys) eV. ; Funding: The BESIII collaboration thanks the staff of BEPCII and the IHEP computing center for their strong support.
