GGR Consortium - Soils Research to deliver Greenhouse Gas REmovals and Abatement Technologies (Soils-R-GGREAT). Scenario modelling studies show that it is unlikely that we will be able to meet the target to limit climate warming to "well below 2 degrees C" outlined in the Paris Agreement without removing a significant quantity of greenhouse gases from the atmosphere. It appears to be virtually impossible to meet the aspirational target of 1.5 degrees C of warming without greenhouse gas removal (GGR) from the atmosphere. Given the importance of GGR for climate stabilization, the global potential, feasibility, barriers and impacts of GGR technologies need to be assessed. Preliminary analysis suggests that widespread implementation of GGRs could have significant impacts on land competition, greenhouse gas emissions, physical climate feedbacks (e.g. albedo), water requirements, nutrient use, energy and cost, but that soil carbon sequestration and biochar used as GGR practices have significant potential for GGR (4-6 thousand million tonnes of carbon dioxide per year, together), and can do so with much less competition for land, water and nutrients than, for example bioenergy with carbon capture and storage and afforestation, and at much lower cost than enhanced mineral weathering and direct air capture of carbon dioxide. In addition, soil-based GGRs could help deliver other Sustainable Development Goals (SDGs), particularly 1, 2, 13 and 15 (poverty, hunger, climate and life on land). Yet constraints due to high uncertainties about the GGR achievable, the need for site-specific options and incentives, social and ecological impacts, and the risk of impermanence have limited soil-based GGR to date. In this project, we will focus on soil carbon sequestration through improved land management, and the addition of biochar to soils to increase soil carbon storage. We will work closely with other consortia to ensure consistency across assumptions about land and resource availability. In the Soils-R-GGREAT project we have harnessed the best expertise in the UK on soils and biochar to provide a comprehensive global assessment of soil-based GGRs. We will use a combination of life cycle assessment (LCA), scenario database analysis, network data analysis, meta-analysis, biophysical modelling, economic modelling, stakeholder engagement and expert consultation to deliver the most rigorous and comprehensive global assessment of potential, feasibility, barriers and impacts of soil-based GGRs. The achievements / outputs from the project will be an assessment of the technical and cost-effective potential for soil-based GGRs globally and regionally, identification of technical options, an assessment of the socio-cultural-ecological impacts of soil-based GGRs and their ability to co-deliver to SDGs 1,2,13,15, an analysis of the current policy barriers preventing implementation and options for future policies to enable widespread adoption of soil-based GGRs, and an assessment of how soil-based GGRs can be integrated into portfolios of other GGR technologies, and other greenhouse gas emission reduction efforts. Interim results will be published by the end of 2017 to feed into the IPCC Special Reports on the "1.5 degree C target", and "land use and climate change".

GGR 联盟 - 提供温室气体清除和减排技术的土壤研究 (Soils-R-GGREAT)。情景模型研究表明，如果不从大气中去除大量温室气体，我们不太可能实现《巴黎协定》中规定的将气候变暖限制在“远低于 2 摄氏度”的目标。如果不从大气中去除温室气体（GGR），似乎几乎不可能实现升温 1.5 摄氏度的理想目标。鉴于 GGR 对气候稳定的重要性，需要评估 GGR 技术的全球潜力、可行性、障碍和影响。初步分析表明，GGR 的广泛实施可能对土地竞争、温室气体排放、物理气候反馈（例如反照率）、需水量、养分利用、能源和成本产生重大影响，但用作 GGR 实践的土壤碳封存和生物炭具有巨大的 GGR 潜力（每年 4-6 亿吨二氧化碳），并且可以在减少对土地、水的竞争的情况下实现这一目标。 和营养物质，例如生物能源与碳捕获和储存以及造林，并且成本比增强矿物风化和直接空气捕获二氧化碳低得多。此外，基于土壤的 GGR 可以帮助实现其他可持续发展目标 (SDG)，特别是 1、2、13 和 15（贫困、饥饿、气候和陆地生物）。然而，由于可实现的 GGR 的高度不确定性、对特定地点的选择和激励措施的需求、社会和生态影响以及无常风险，迄今为止，土壤 GGR 受到限制。在这个项目中，我们将通过改善土地管理以及在土壤中添加生物炭来增加土壤碳储存来重点关注土壤碳封存。我们将与其他联盟密切合作，确保有关土地和资源可用性的假设的一致性。在 Soils-R-GGREAT 项目中，我们利用了英国在土壤和生物炭方面最好的专业知识，对基于土壤的 GGR 进行了全面的全球评估。我们将结合生命周期评估（LCA）、情景数据库分析、网络数据分析、荟萃分析、生物物理建模、经济建模、利益相关者参与和专家咨询，对土壤GGR的潜力、可行性、障碍和影响提供最严格和全面的全球评估。该项目的成就/产出将包括评估全球和区域土壤 GGR 的技术和成本效益潜力、确定技术方案、评估土壤 GGR 的社会文化生态影响及其共同实现可持续发展目标 1、2、13、15 的能力、分析当前阻碍实施的政策障碍以及未来政策选择，以促进广泛采用土壤 GGR GGR，以及对如何将土壤 GGR 纳入其他 GGR 技术组合以及其他温室气体减排工作的评估。中期结果将于2017年底发布，纳入IPCC关于“1.5摄氏度目标”和“土地利用与气候变化”的特别报告中。
