TL;DR: It is shown that implementation of current policies leaves a median emission gap of 22.4 to 28.2 GtCO 2 eq by 2030 with the optimal pathways to implement the well below 2 °C and 1.5‬C Paris goals, which shows that all countries would need to accelerate the implementation of policies for renewable technologies, while efficiency improvements are especially important in emerging countries and fossil-fuel-dependent countries.

TL;DR: In this paper, the authors provided emission projections for China up to 2030 given current policies and a selected set of enhanced policies, and compared the results with projected CO2 emission trajectories that are consistent with the announced target for 2030.

TL;DR: In this paper, the authors show that a country's potential for negative emissions and methodological issues affect when countries can reach net-zero, calling for clear internationally agreed definitions and accounting methods.

TL;DR: In this article, the authors analyzed how country-level emission targets and carbon budgets can be derived based on such criteria and showed that effort-sharing approaches that (i) calculate required reduction targets in carbon budgets (relative to baseline budgets) and/or (ii) take into account historical emissions when determining carbon budget can lead to (large) negative remaining carbon budgets for developed countries.

TL;DR: In this article, the authors compare the key interactions identified among the SDGs in an expert survey, with their current and planned representation in models as identified in a survey among modellers.
