Greenhouse gas removal (GGR) approaches are considered essential in several projections to meet the climate mitigation ambition of the Paris Agreement. Biomass Energy with Carbon Capture and Storage (BECCS) and afforestation are included extensively in mitigation scenarios but there are concerns about the feasibility of these approaches. This was explored with stakeholders from industry, non-governmental organisations (NGOs) and policy who were involved in interviews and a one-day participatory workshop. Multicriteria mapping (MCM) methodology was used to appraise the ‘real-world’ feasibility of four specific greenhouse gas removal supply chains at a granular level in the UK context. The MCM analysis shows that afforestation performs better in comparison to three BECCS supply chains, on criteria such as business model, social acceptability, and environmental sustainability. This innovative application of the MCM methodology enables the abstract representations of GGR in integrated assessment models to be explored at a more granular level through a supply chain analysis and thus gain a deeper understanding of the issues facing these approaches. The data gathered allows a wide range of technical, environmental, social and political criteria to be systematically applied in appraising the practical performance of different future implementation options for afforestation and BECCS. If these GGR supply chains are to become a reality on the scale required for 1.5 °C global warming, factors such as global cooperation, land availability, and the longevity of policies and incentives were found to be major challenges.

将温室气体清除带到地球上:利益相关者供应链评估揭示了复杂的挑战

在多项预测中,温室气体去除 (GGR) 方法被认为是实现《巴黎协定》减缓气候变化目标的必要条件。具有碳捕获和储存功能的生物质能源 (BECCS) 和植树造林广泛包含在缓解方案中,但人们担心这些方法的可行性。来自行业、非政府组织 (NGO) 和政策的利益相关者参与了访谈和为期一天的参与式研讨会,对此进行了探讨。多标准映射 (MCM) 方法用于在英国范围内在粒度级别上评估四个特定温室气体清除供应链的“现实世界”可行性。MCM 分析表明,与三个 BECCS 供应链相比,在商业模式、社会可接受性、和环境可持续性。MCM 方法的这种创新应用使综合评估模型中 GGR 的抽象表示能够通过供应链分析在更细粒度的级别上进行探索,从而更深入地了解这些方法面临的问题。收集的数据允许系统地应用广泛的技术、环境、社会和政治标准,以评估未来不同的造林和 BECCS 实施方案的实际绩效。如果这些 GGR 供应链要在全球变暖 1.5°C 所需的规模上成为现实,全球合作、土地可用性以及政策和激励措施的寿命等因素被认为是主要挑战。MCM 方法的这种创新应用使综合评估模型中 GGR 的抽象表示能够通过供应链分析在更细粒度的级别上进行探索,从而更深入地了解这些方法面临的问题。收集的数据允许系统地应用广泛的技术、环境、社会和政治标准,以评估未来不同的造林和 BECCS 实施方案的实际绩效。如果这些 GGR 供应链要在全球变暖 1.5 °C 所需的规模上成为现实,全球合作、土地可用性以及政策和激励措施的寿命等因素被认为是主要挑战。MCM 方法的这种创新应用使综合评估模型中 GGR 的抽象表示能够通过供应链分析在更细粒度的级别上进行探索,从而更深入地了解这些方法面临的问题。收集的数据允许系统地应用广泛的技术、环境、社会和政治标准,以评估未来不同的造林和 BECCS 实施方案的实际绩效。如果这些 GGR 供应链要在全球变暖 1.5 °C 所需的规模上成为现实,全球合作、土地可用性以及政策和激励措施的寿命等因素被认为是主要挑战。
