The production of palm oil, soy, beef and timber are key drivers of global forest loss. For this reason, over 470 companies involved in the production, processing or distribution of these commodities have issued commitments to eliminate or reduce deforestation from their supply chains. However, the effectiveness of these commitments is uncertain since there is considerable variation in ambition and scope and there are no globally agreed definitions of what constitutes a forest. Many commitments identify high conservation value forests (HCVFs), high carbon stock forests (HCSFs) and forests on tropical peatland as priority areas for conservation. This allows for mapping of the global extent of forest areas classified as such, to achieve an assessment of the area that may be at reduced risk of development if companies comply with their zero deforestation commitments. Depending on the criteria used, the results indicate that between 34% and 74% of global forests qualify as either HCVF, HCSF or forests on tropical peatland. However, we found that the total extent of these forest areas varies widely depending on the choice of forest map. Within forests which were not designated as HCVF, HCSF or forests on tropical peatland, there is substantial overlap with areas that are highly suitable for agricultural development. Since these areas are unlikely to be protected by zero-deforestation commitments, they may be subject to increased pressure resulting from leakage of areas designated as HCVF, HCSF and tropical peatland forests. Considerable uncertainties around future outcomes remain, since only a proportion of the global market is currently covered by corporate commitments. Further work is needed to map the synergies between corporate commitments and government policies on land use. In addition, standardized criteria for delineating forests covered by the commitments are recommended.

企业零毁林承诺可以保护哪些森林？空间评估。

棕榈油、大豆、牛肉和木材的生产是全球森林流失的主要驱动因素。出于这个原因，参与这些商品的生产、加工或分销的 470 多家公司已承诺在其供应链中消除或减少森林砍伐。然而，这些承诺的有效性尚不确定，因为雄心和范围存在很大差异，而且对于森林的构成也没有全球公认的定义。许多承诺将高保护价值森林 (HCVF)、高碳储量森林 (HCSF) 和热带泥炭地森林确定为优先保护领域。这允许绘制这样分类的森林区域的全球范围，如果公司遵守其零毁林承诺，则对可能会降低发展风险的区域进行评估。根据所使用的标准，结果表明，全球 34% 至 74% 的森林符合 HCVF、HCSF 或热带泥炭地森林的条件。然而，我们发现这些森林区域的总范围因森林地图的选择而异。在未被指定为 HCVF、HCSF 或热带泥炭地森林的森林中，与非常适合农业发展的地区存在大量重叠。由于这些地区不太可能受到零毁林承诺的保护，因此它们可能会因指定为 HCVF、HCSF 和热带泥炭地森林的区域泄漏而承受更大的压力。未来结果仍然存在相当大的不确定性，因为目前只有一部分全球市场由企业承诺覆盖。需要开展进一步的工作来绘制企业承诺与政府土地使用政策之间的协同作用。此外，建议采用标准化的标准来划分承诺所涵盖的森林。
