The Food and Agriculture Organization of the United Nations suggests that US$110 billion were spent on fertilizer imports in 2021 globally. Such fertilizers are generally manufactured using fossil fuels, and ammonia is responsible for 2% of global fossil fuel use¹. Imports of carbon-intensive fertilizer are part of the total bill for many agricultural fertilizer subsidy programmes^2,3.

To transition away from fertilizer dependence, farmers need investment in education and training in sustainable alternatives. The lag between learning how to reduce the use of purchased inputs and the profitable implementation of that learning requires bridge financing. One approach, building on the idea of ‘pay for success’ social impact bonds, is that of environmental impact bonds.

联合国粮食及农业组织表示，2021 年全球化肥进口支出为 1100 亿美元。此类肥料通常使用化石燃料制造，而氨占全球化石燃料使用量的 2% ¹ 。进口碳密集型肥料是许多农业肥料补贴计划总费用的一部分^2,3 。

为了摆脱对化肥的依赖，农民需要对可持续替代品的教育和培训进行投资。学习如何减少购买投入的使用与学习的有利可图的实施之间的滞后需要过渡融资。一种基于“为成功付费”社会影响债券理念的方法是环境影响债券。
