Peatlands store more carbon than any other terrestrial ecosystem, both in the UK and globally. As a result of human disturbance they are rapidly losing this carbon to the atmosphere, contributing significantly to global greenhouse gas emissions and climate change. We propose to turn this problem into a solution, by re-establishing and augmenting the unique natural capacity of peatlands to remove CO2 from the atmosphere and to store it securely for millennia. We will do this by working with natural processes to recreate, and where possible enhance, the environmental conditions that lead to peat formation, in both lowland and upland Britain. At the same time, we will optimise conditions to avoid emissions of methane and nitrous oxide that could offset the benefits of CO2 removal; develop innovative cropping and management systems to augment rates of CO2 uptake; evaluate whether we can further increase peat carbon accumulation through the formation and addition of biomass and biochar; and develop new economic models to support greenhouse gas removal by peatlands as part of profitable and sustainable farming and land management systems. Implementation of these new approaches to the 2.3 million hectares of degraded upland and lowland peat in the UK has the potential to remove significant quantities of greenhouse gases from the atmosphere, to secure carbon securely and permanently within a productive, biodiverse and self-sustaining ecosystem, and thereby to help the UK to achieve its ambition of having net zero greenhouse gas emissions by 2050.

无论是在英国还是在全球，泥炭地比任何其他陆地生态系统都储存更多的碳。由于人类的干扰，它们正在迅速将这些碳排放到大气中，大大加剧了全球温室气体排放和气候变化。我们建议将这个问题转化为解决方案，通过重建和增强泥炭地独特的自然能力，从大气中去除二氧化碳，并将其安全地储存数千年。我们将通过与自然过程的合作来实现这一目标，并在可能的情况下增强导致英国低地和高地泥炭形成的环境条件。与此同时，我们将优化条件，以避免甲烷和一氧化二氮的排放，这可能抵消二氧化碳去除的好处;开发创新的种植和管理系统，以提高二氧化碳吸收率;评估我们是否可以通过形成和添加生物质和生物炭来进一步增加泥炭碳的积累;并开发新的经济模式，支持泥炭地的温室气体清除，作为有利可图和可持续的农业和土地管理系统的一部分。在英国230万公顷退化高地和低地泥炭地实施这些新方法，有可能从大气中清除大量温室气体，在一个多产、生物多样性和自我维持的生态系统中安全、永久地保护碳，从而帮助英国实现到2050年实现温室气体净零排放的目标。
