土壤具有封存和储存大量碳的潜力，有助于减缓气候变化。土壤碳市场正在兴起，以向农民支付吸收大气碳的管理变化的费用，这些市场的管理规范确保资格、额外性和持久性，同时防止泄漏和逆转。这篇论文首次对农田土壤碳代码进行了全球比较分析，为管理这一全球市场的各种方法提供了新的见解。为此，本文开发了一个分析框架，用于系统地比较代码，用于确定来自世界各地的12个公开可用代码在途径、方法、管理、商业化和操作方面的共性和差异。准则使用了一系列机制来管理额外性、不确定性和风险、基线、衡量、报告和核查、审计、转售碳单位、捆绑和堆放、利益攸关方参与和市场诚信。论文最后讨论了可以在英国使用的现有方法和代码，并评估了英国和国际上土壤碳代码的总体标准的必要性，现有的代码和其他已经产生土壤碳信用的计划可以根据该标准进行评估和基准。
Soils have the potential to sequester and store significant amounts of carbon, contributing towards climate change mitigation. Soil carbon markets are emerging to pay farmers for management changes that absorb atmospheric carbon, governed by codes that ensure eligibility, additionality and permanence whilst protecting against leakage and reversals. This paper presents the first global comparative analysis of farmland soil carbon codes, providing new insights into the range of approaches governing this global marketplace. To do this, the paper developed an analytical framework for the systematic comparison of codes which was used to identify commonalities and differences in approaches, methods, administration, commercialisation and operations for 12 publicly available codes from around the world. Codes used a range of mechanisms to manage additionality, uncertainty and risks, baselines, measurement, reporting and verification, auditing, resale of carbon units, bundling and stacking, stakeholder engagement and market integrity. The paper concludes by discussing existing approaches and codes that could be adapted for use in the UK and evaluates the need for an over-arching standard for soil carbon codes in the UK and internationally, to which existing codes and other schemes already generating soil carbon credits could be assessed and benchmarked.
