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 - 土壤研究，用于提供温室气体去除和减排技术（土壤R-Great）。方案建模研究表明，我们不可能达到目标，以将气候变暖限制在巴黎一致性中概述的“远低于2度C”，而不会消除大气中的大量温室气体。在没有大气中的温室气体去除（GGR）的情况下，几乎不可能实现1.5度C变暖的理想目标。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。 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和养分相比，例如具有碳捕获和储存和造林的生物能源，其成本比增强的矿物风化和直接的二氧化碳的空气捕获要低得多。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，气候和土地上的生命）。然而，由于对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的风险的限制造成的限制有限。在这个项目中，我们将通过改进的土地管理重点关注土壤碳固执，并将生物炭添加到土壤中以增加土壤碳储存。我们将与其他财团紧密合作，以确保跨关于土地和资源可用性的假设的一致性。在《土壤R-Great项目》中，我们利用了英国在土壤和生物炭方面的最佳专业知识，以对基于土壤的GGR进行全面评估。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，以提供对基于土壤GGRS的潜在潜在，可行性，障碍和影响的最严格，最全面的全球评估。该项目的成就 /成果将是对全球和区域上基于土壤的GGR的技术和成本效益潜力的评估，对技术选择的识别，对基于土壤的GGR的社会文化生态影响的评估，以及对SDGS的共同行动的能力，可预防目前的策略，以对目前的策略进行共同行动，并分析启用的实施方案，并分析启用的景点。 GGRS，以及如何将基于土壤的GGR集成到其他GGR技术的投资组合以及其他温室气体排放量的工作中。临时结果将于2017年底发布，以介绍有关“ 1.5级C目标”和“土地利用和气候变化”的IPCC特别报告。
