Two Decades of Climate Leadership
Boston Common’s History of Decarbonizing Portfolios
Boston Common is a leading investor voice on sustainability issues. Before climate change was a mainstream concern, we engaged companies to improve operations, reduce GHG emissions, and increase efficiency. We avoid investments in the worst contributors to climate change, choosing instead to invest in companies focused on renewable energy, climate change mitigation and adaptation, process efficiency, and economic circularity.


Emerging Markets
Unlocking Sustainable Growth
The Emerging Markets strategy report highlights decade-long engagements with diversified portfolio companies.
Key themes include:
- ESG investing in Emerging Markets (“EM”) is evolving from traditional risk mitigation to alpha generation.
- EM companies are leading sustainability adopters on the global ESG stage.
- Shareholder Engagement has helped raise the bar on ESG—at the company, regulatory, & exchange levels.
