A Workshop on Aligning Goals for the Development of a Global Roadmap for Achieving Negative Emissions on the Order of a Gigaton by Mid-Century

该研讨会将汇集一小群负排放技术（NET）各个领域的思想领袖，包括土地管理，加速风化，生物能源与碳捕获和储存，以及直接空气捕获与储存。该研讨会旨在建立一个为期一年的研究框架，每个与会者都在其主要专业领域工作，但朝着一个共同的目标，即制定一个路线图，到世纪中期实现全球负排放量达到10亿吨。据设想，全球范围内部署的净将有显着的影响，在减少大气中的二氧化碳浓度到安全水平的一部分，全球努力实现低于2？到世纪末，全球气温将会上升。为了有效实现这一愿景，“全球负排放技术测绘”研讨会及相关后续活动将评估NET在不同情景和多个实施阶段的机会和影响。需要对各种技术选择下的全球负排放潜力进行全面测绘和选址，并评估影响，以便更深入地了解NET的可行和可持续发展及其多种相互作用。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The workshop will bring together a small group of thought leaders in the various sectors of Negative Emissions Technologies (NETs), including land management, accelerated weathering, bioenergy with carbon capture and storage, and direct air capture with storage. The workshop is intended to establish a framework for a 1-year study in which each of the attendees works in their primary area of expertise, but toward a common goal of developing a roadmap to achieving global negative emissions on the order of a gigaton by mid- century. It is envisioned that global coverage of deployed NETs will have significant impact in reducing atmospheric CO2 concentration to safe levels as part of the global effort to achieve lower than 2 ?C warming by the end of the century. In order to effectively realize this vision, the workshop, "Global Mapping of Negative Emissions Technologies," and associated follow-up will assess the opportunities and impacts of NETs in different scenarios and multiple stages of implementation. Comprehensive mapping and siting of global potentials for negative emissions under various options of technologies and assessment of impacts are needed to provide richer understanding for the feasible and sustainable development of NETs and their multiple interactions. Such mapping will also provide policymakers, businesses, and investors with information needed to finance initial negative emissions projects of the highest value.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
