Parties to the United Nations Convention on Biological Diversity (CBD) will meet at the 15th Conference of Parties (COP 15) to carve out a post-2020 framework for global biodiversity conservation. Finance will be among the priority concerns. No global estimates of public biodiversity investments are in the peer reviewed literature. The methodology developed by the Biodiversity Finance Initiative (BIOFIN) provides a means for countries to account systematically for their biodiversity expenditures. Importantly, budget lines that intentionally, but secondarily, affect biodiversity outcomes are assigned a percentage at which they can be attributed to biodiversity. A sample of thirty countries facilitated the construction of a panel to predict public biodiversity investments at a global level. Here we show that global public biodiversity investments have increased steadily to an average of US$121 billion invested annually from 2008–2017, or 0.19–0.25% of global GDP. Our data not only indicate an increasing trend in total biodiversity investment, but also an increase in the percentage of total public domestic investment dedicated to biodiversity.

《联合国生物多样性公约》（CBD）的缔约方将在第十五届缔约方会议（COP 15）上开会，以制定2020年后全球生物多样性保护框架。财务将是优先考虑的问题。同行评审的文献中没有全球公共生物多样性投资的估计。生物多样性融资倡议（BIOFIN）开发的方法为各国提供了一种系统地对其生物多样性支出进行核算的手段。重要的是，将有意但次要影响生物多样性成果的预算项目分配给可归因于生物多样性的百分比。30个国家的样本促进了一个小组的建立，以预测全球范围内的公共生物多样性投资。在这里，我们表明，全球公共生物多样性投资稳步增长，从2008年至2017年，每年平均投资1210亿美元，占全球GDP的0.19％至0.25％。我们的数据不仅表明生物多样性总投资呈增长趋势，而且致力于生物多样性的公共国内总投资百分比也有所增加。
