TL;DR: In this article, the authors investigated five equitable approaches to mitigation and found that most developing countries are more ambitious than the average, whilst if developed nations and China adopted the average of the approaches the gap between INDCs and a 2'°C pathway would narrow.

TL;DR: In this article, the authors assessed approaches to setting country-level mitigation targets in line with the 2'°C goal, breaking away from the utopian assumption that the international community will agree on a single emissions allocation scheme.

TL;DR: It is shown that the global 2030-emissions of NDCs match the sum of each country adopting the least-stringent of five effort-sharing allocations of a well-below 2 °C-scenario, which reconciles the bottom-up nature of the Paris Agreement with its top-down warming thresholds and provides a temperature metric to assess N DCs.

TL;DR: In this paper, the authors identify global cost-optimal emissions scenarios from Integrated Assessment Models that match the G7 agreement and allocate emissions from these global scenarios to countries according to five equity approaches representative of the five equity categories presented in the Fifth Assessment Report of the IPCC (IPCCAR5): "capability", "equality", "responsibility-capability-need", "equal cumulative per capita" and "staged approaches".

TL;DR: The 2030 assessment of the NDC for the USA was misplotted and the number of equity approaches that the USA's NDC was in line with changed.
