It emphasizes the need to mobilize capital for nature conservation by transforming the policy environment, proving viable business models, and harnessing financial innovation. Nature finance should drive more capital “into” nature, but also “for” nature. The report calls on a “whole of economy approach” that addresses cross-sector drivers of nature loss. |

■ Tackling international spillovers: an overview of policy options
| Author | Ishii, N., Schmidt-Traub, G., Lafortune, G., Franke, J., Cornehl, F., and von Preussen, A. |

| Overview | This report introduces a framework for understanding how four types of national policy levers can tackle international spillovers: (1) target setting and monitoring; (2) public management; (3) regulation; and (4) fiscal policy and financing. It considers both demand and supply-side policy instruments and their impacts on the global commons, and highlights practical lessons on how national policymakers can begin to act now. This paper identifies a number of actionable steps that can vastly improve the governance—broadly understood—of the global commons. |

| Overview | Chemical products support modern life in various ways, but they also pose environmental challenges. In particular, reducing greenhouse gas emissions is an urgent issue, while the chemical industry faces technological difficulties and uncertainties in achieving net zero. To address these challenges, we have made recommendations for the chemical industry to achieve net zero within the Planetary Boundaries. These include a transition in raw materials, as well as the use of renewable energy and carbon capture and storage. |
