Abstract

Forest carbon sequestration offsets are methodologically uncertain, comprise a minor component of carbon markets and do not effectively slow deforestation. The objective of this study is to describe a commercial scale in situ measurement approach for determination of net forest carbon sequestration projects, the Direct Measurement Forest Carbon Protocol™, to address forest carbon market uncertainties. In contrast to protocols that rely on limited forest mensuration, growth simulation and exclusion of CO data, the Direct Measurement Forest Carbon Protocol™ is based on standardized methods for direct determination of net ecosystem exchange (NEE) of CO employing eddy covariance, a meteorological approach integrating forest carbon fluxes. NEE is used here as the basis for quantifying the first of its kind carbon financial products. The DMFCP differentiates physical, project and financial carbon within a System-of-Systems™ (SoS) network architecture. SoS sensor nodes, the Global Monitoring Platform™ (GMP), housing analyzers for CO isotopologues (e.g., CO CO, CO) and greenhouse gases are deployed across the project landscape. The SoS standardizes and automates GMP measurement, uncertainty and reporting functions creating diverse forest carbon portfolios while reducing cost and investment risk in alignment with modern portfolio theory. To illustrate SoS field deployment and operation, published annual NEE data for a tropical (Ankasa Park, Ghana, Africa) and a deciduous forest (Harvard Forest, Petersham, MA, USA) are used to forecast carbon revenue. Carbon pricing scenarios are combined with historical in situ NEE annual time-series to extrapolate pre-tax revenue for each project applied to 100,000 acres (40,469 hectares) of surrounding land. Based on carbon pricing of $5 to $36 per ton CO equivalent (tCOeq) and observed NEE sequestration rates of 0.48 to 15.60 tCOeq acre yr, pre-tax cash flows ranging from $230,000 to $16,380,000 across project time-series are calculated, up to 5×  revenue for contemporary voluntary offsets, demonstrating new economic incentives to reverse deforestation. The SoS concept of operation and architecture, with engineering development, can be extended to diverse gas species across terrestrial, aquatic and oceanic ecosystems, harmonizing voluntary and compliance market products worldwide to assist in the management of global warming. The Direct Measurement Forest Carbon Protocol reduces risk of invalidation intrinsic to estimation-based protocols such as the Climate Action Reserve and the Clean Development Mechanism that do not observe molecular CO to calibrate financial products. Multinational policy applications such as the Paris Agreement and the United Nations Reducing Emissions from Deforestation and Degradation, constrained by Kyoto Protocol era processes, will benefit from NEE measurement avoiding unsupported claims of emission reduction, fraud, and forest conservation policy failure.

摘要

森林碳封存抵消在方法上存在不确定性,在碳市场中占比小,且无法有效减缓森林砍伐。本研究的目的是描述一种用于确定森林净碳封存项目的商业规模现场测量方法——直接测量森林碳协议™,以解决森林碳市场的不确定性问题。与依赖有限森林测量、生长模拟和排除二氧化碳数据的协议不同,直接测量森林碳协议™基于采用涡度协方差直接测定二氧化碳净生态系统交换(NEE)的标准化方法,这是一种整合森林碳通量的气象方法。在此,NEE被用作量化同类首个碳金融产品的基础。直接测量森林碳协议在系统-of-系统™(SoS)网络架构内区分物理碳、项目碳和金融碳。SoS传感器节点,即全球监测平台™(GMP),配备用于二氧化碳同位素异构体(如¹²CO₂、¹³CO₂、¹⁴CO₂)和温室气体的分析仪,部署在整个项目区域。SoS对GMP的测量、不确定性和报告功能进行标准化和自动化,创建多样化的森林碳投资组合,同时根据现代投资组合理论降低成本和投资风险。为说明SoS的现场部署和运行情况,利用已发表的热带森林(非洲加纳安卡萨公园)和落叶林(美国马萨诸塞州彼得舍姆哈佛森林)的年度NEE数据来预测碳收入。碳定价情景与历史现场NEE年度时间序列相结合,推断每个应用于10万英亩(40469公顷)周边土地的项目的税前收入。基于每吨二氧化碳当量(tCO₂eq)5至36美元的碳定价以及观测到的0.48至15.60 tCO₂eq/英亩·年的NEE封存率,计算出项目时间序列内23万美元至1638万美元的税前现金流,是当代自愿抵消项目收入的5倍之多,显示出扭转森林砍伐的新经济激励措施。SoS的运行概念和架构以及工程开发可扩展到陆地、水生和海洋生态系统中的各种气体物种,协调全球范围内的自愿和合规市场产品,以协助应对全球变暖。直接测量森林碳协议降低了基于估计的协议(如气候行动储备和清洁发展机制)固有的无效风险,这些协议未观测分子二氧化碳来校准金融产品。受京都议定书时代流程限制的跨国政策应用,如《巴黎协定》和联合国减少毁林和森林退化所致排放,将受益于NEE测量,避免减排无依据的声称、欺诈以及森林保护政策失败。
