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 article, the authors highlight the opportunities and risks of e-fuels, and conclude that hydrogen and e-Fuels should be prioritized for sectors inaccessible to direct electrification.

TL;DR: The authors quantify environmental co-benefits and adverse side-effects of a portfolio of alternative power sector decarbonisation pathways and show that the scale of co-Benefits as well as profiles of adverse side effects depend strongly on technology choice.

TL;DR: In this article, the authors propose diagnostic indicators to characterize model responses to carbon price signals and test these in a diagnostic study of 11 global models, showing a correlation among indicators suggesting that models can be classified into groups based on common patterns of behavior in response to carbon pricing.

TL;DR: In this paper, the authors quantify climate and SDG outcomes, showing that strong interventions across many dimensions, together with ambitious lifestyle change, are needed to enable real progress towards the UN Agenda 2030.
