We map and quantify biodiversity impacts and ecosystem service (ES) dependencies associated with global equity ownership. By integrating firm-level financial ownership data (Orbis), multi-regional input-output analysis (GLORIA), and life-cycle assessment (LC-IMPACT), we link shareholder portfolios to spatially explicit measures of land-use-driven biodiversity impact and ES dependencies. Our dataset covers listed companies representing USD 121.7 trillion in market capitalization (≈96% of global market capitalization) and ~336,000 ultimate shareholders holding USD 54.1 trillion in equity. Shareholders' biodiversity footprints are highly concentrated in Latin America and Asia, and the ownership of impactful activities is mostly regional. However, shareholders in North America and Western Europe account for a disproportionate share of ownership in impactful activities beyond their own region. ES in China, and to a lesser extent the United States, are critical for both regional and extra-regional investors. Portfolio-level geographical overlap between impacts and dependencies typically remains below 40% suggesting that risk-based incentives alone may be insufficient to align financial flows with biodiversity outcomes.
