Ten years after the Paris Agreement, global climate action has bent the curve of projected warming, but a temporary overshoot of 1.5°C is now unavoidable. Even full implementation of all announced NDCs, long-term strategies and net-zero pledges falls well short of what's needed, and global emissions continue to rise. This session looks to explore how we can achieve the lowest temperature outcome feasible in 2100, as well as the timing of net-zero greenhouse gas emissions globally, in line with the requirements of the Paris Agreement and Article 4.1. We do this through three angles: where we stand, where we are headed, and how to get back on track.

First, where the world stands. The latest climate science is essential to understand the actions necessary to minimize the extent and duration of overshoot. Here we welcome submissions that quantify the latest science around anthropogenic emissions and warming, or that assess changes in the Earth system with implications for overshoot such as updates to climate sensitivity or tipping point dynamics. At the same time, continued development and technological progress is potentially opening up new opportunities (and challenges) for mitigation pathways, looking across developments in electro-tech, innovative new technologies, and AI. We welcome submissions which capture these latest developments and explore how they could impact on mitigation pathways.

Second, where the world is heading under current policies and targets. We welcome submissions that quantify our current emissions and energy system trajectories and assess the implications of this for global temperatures and associated impacts.

Third, where we need to go: what it will take to limit the magnitude and duration of any eventual overshoot. Here we welcome submissions that cover the pace and shape of decarbonization pathways able to limit peak warming and bring temperatures back down after mid-century, through multiple interlinked levers including fossil fuel phase-out; electrification of buildings, transport and industry; methane abatement and other short-lived climate pollutants (SLCPs); and scaling up carbon dioxide removal. We are particularly interested in assessing the feasibility of different options, and aim to interrogate the actions that can most plausibly limit the magnitude and duration of overshoot. Each of these levers is examined at global, regional and sectoral resolution.
