The EU biodiversity strategy highlights the relevance of the private sector and its prominent role as potential degrader and as protector of biodiversity. However, the topic of biodiversity seems to be downplayed and disregarded by most companies, and the potential proxies leading them to report on the matter are not yet clear.

This exploratory paper aims at assessing the companies' actual engagement with the EU biodiversity strategy, and the factors influencing the relevance and quality of their disclosure indicators. To that purpose, 170 listed companies from the 5 biggest economies in the EU have been studied after their reporting indicators on biodiversity in 2018 and 2021, focusing on country, sector and impact intensity as potential drivers, as well as on the changes in reporting and indicators between those years.

Our findings highlight an increased but heterogeneous engagement with biodiversity among EU listed companies, with limited relevance given by the companies to standard and quantitative performance indicators, and a strong influence on reporting of factors such as the companies' country of origin, and the companies' sector/activity. All of which suggests different approaches to biodiversity within the private sector and insufficient corporate action to meet the EU biodiversity strategy goals.

欧盟生物多样性战略强调了私营部门的相关性及其作为生物多样性潜在降解者和保护者的突出作用。然而，生物多样性这个话题似乎被大多数公司淡化和忽视，导致他们报告此事的潜在代理人尚不清楚。

这份探索性文件旨在评估公司对欧盟生物多样性战略的实际参与情况，以及影响其披露指标的相关性和质量的因素。为此，在 2018 年和 2021 年的生物多样性报告指标后，对来自欧盟 5 个最大经济体的 170 家上市公司进行了研究，重点关注作为潜在驱动因素的国家、部门和影响强度，以及报告和这些年之间的指标。

我们的调查结果突出表明，欧盟上市公司在生物多样性方面的参与有所增加但存在差异，公司对标准和量化绩效指标的相关性有限，并且对公司原产国和公司的部门/活动。所有这些都表明私营部门对生物多样性采取不同的方法，而且企业行动不足以实现欧盟生物多样性战略目标。
