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

研讨会将汇集负排放技术(NETS)各个领域的一小部分思想领袖，包括土地管理、加速风化、碳捕获和储存的生物能源，以及直接空气储存。研讨会旨在为为期一年的研究建立一个框架，在这项研究中，每个与会者都在各自的主要专业领域工作，但朝着一个共同目标努力，即制定路线图，在本世纪中叶实现全球约10亿吨的负排放。据设想，部署蚊帐的全球覆盖范围将对将大气二氧化碳浓度降低到安全水平产生重大影响，这是全球努力的一部分，目的是在本世纪末实现低于2摄氏度的变暖。为了有效实现这一愿景，题为“负排放技术全球图谱”的讲习班和相关后续行动将评估网络技术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的测绘和定位，并评估影响，以便更好地了解网络的可行和可持续发展及其多重相互作用。这种映射还将为政策制定者、企业和投资者提供为最高价值的初始负排放项目提供资金所需的信息。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势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.
