Alongside the steep reductions needed in fossil fuel emissions, natural climate solutions (NCS) represent readily deployable options that can contribute to Canada's goals for emission reductions. We estimate the mitigation potential of 24 NCS related to the protection, management, and restoration of natural systems that can also deliver numerous co-benefits, such as enhanced soil productivity, clean air and water, and biodiversity conservation. NCS can provide up to 78.2 (41.0 to 115.1) Tg COe/year (95% CI) of mitigation annually in 2030 and 394.4 (173.2 to 612.4) Tg COe cumulatively between 2021 and 2030, with 34% available at ≤CAD 50/Mg COe. Avoided conversion of grassland, avoided peatland disturbance, cover crops, and improved forest management offer the largest mitigation opportunities. The mitigation identified here represents an important potential contribution to the Paris Agreement, such that NCS combined with existing mitigation plans could help Canada to meet or exceed its climate goals.
除了大幅减少化石燃料排放外，自然气候解决方案（NCS）是易于实施的选项，有助于加拿大实现减排目标。我们评估了24种与自然系统保护、管理和恢复相关的自然气候解决方案的减排潜力，这些方案还能带来诸多协同效益，如提高土壤生产力、提供清洁空气和水以及保护生物多样性。到2030年，自然气候解决方案每年可提供高达78.2（41.0至115.1）Tg COe/年（95%置信区间）的减排量，2021年至2030年累计减排394.4（173.2至612.4）Tg COe，其中34%的减排成本低于50加元/ Mg COe。避免草地转化、避免泥炭地扰动、覆盖作物以及改善森林管理提供了最大的减排机会。此处确定的减排量对《巴黎协定》具有重要潜在贡献，因此自然气候解决方案与现有减排计划相结合可帮助加拿大实现或超越其气候目标。
