How This Leading Strategy Works in Practice
To fully grasp what is the largest sustainable investment strategy globally, it’s essential to understand its mechanics. Corporate engagement and shareholder action is a proactive approach where investors use their shareholder rights to influence a company’s operations and policies. This is accomplished through several key methods:
- Direct Dialogue: This involves one-on-one or group meetings between investors (often large institutional ones like pension funds or asset managers) and a company’s board of directors or management team. These discussions can cover a range of ESG topics, from setting carbon emissions targets to improving labor practices in the supply chain.
- Shareholder Resolutions: If dialogue fails or a more formal approach is needed, investors can file shareholder proposals. These are formal requests submitted for a vote at a company’s annual general meeting. While often non-binding, they are a powerful way to draw public attention to an issue and pressure the board to act.
- Proxy Voting: Every shareholder has the right to vote on key corporate matters, including the election of directors and shareholder resolutions. A coordinated voting effort by a group of sustainability-focused investors can have a significant impact on a company’s governance and strategic direction. This is a fundamental tool for anyone employing what is the largest sustainable investment strategy globally.
