How We Integrate ESG Into Investment Decisions

At Zevin, environmental, social, and governance (ESG) research is integrated throughout our investment process. We believe that combining ESG insights with rigorous financial analysis provides a more complete understanding of a company's long-term risks and opportunities.

Our approach goes beyond ESG scores. We combine third-party data with proprietary research, direct engagement, and insights from a broad network of experts and stakeholders to develop a more complete view of the companies we invest in.

What Makes Zevin Different?

We Go Beyond ESG Ratings
Third-party ESG data is a starting point, not the conclusion. We use sources such as Bloomberg and GaiaLens to identify controversies and potential areas of concern, then conduct our own research to understand what those issues mean for the company and its long-term prospects.
We Seek Out Primary Sources
Our research draws on government databases, regulatory filings, NGOs, research organizations, labor unions, community leaders, and grassroots organizations. These relationships can provide on-the-ground perspectives and help us identify emerging risks that conventional financial data may miss.
ESG Findings Inform Decisions
SG research directly informs investment decisions. Material concerns may lead us to avoid an investment, engage with a company, or reconsider an existing holding.

Our Investment Process

Four stages of disciplined portfolio construction and management.

Monitor & Engage

Monitor holdings, engage on material issues, and reassess as needed.

Why ESG Matters

Today's investment risks don't always appear on a balance sheet.

How they treat employees, manage environmental risks, govern their businesses, and engage with customers and communities can all influence long-term financial performance.

By evaluating these factors alongside traditional financial metrics, we seek to:

Identify risks before they become financial liabilities.
Recognize long-term opportunities.
Build more resilient portfolios.
Better understand how businesses create sustainable value.

When material ESG concerns arise, we increase our scrutiny, engage with company management, and reassess the investment as needed.

Our Approach

Many investors rely heavily on third-party ESG ratings. We look beyond ESG scores.

While external research is a valuable starting point, we believe meaningful insight comes from combining multiple perspectives with our own independent analysis and engagement.

Our investment team uses:

Fundamental company research
Third-party ESG data
Primary research
Direct engagement
Industry expertise

This helps us develop a more nuanced understanding than a simple ESG score can provide.

Screening

We apply both negative and positive screens to our clients’ portfolios — excluding companies whose business practices are not in keeping with our standards of social responsibility, and actively seeking companies whose products, services, or practices contribute positively to society.

Proxy Voting

On behalf of our clients, we vote on issues before the boards of companies in our clients’ portfolios in annual company meetings. All voting decisions are intended to meet our fiduciary obligations to our clients, which include support for high standards of corporate governance as well as social and environmental responsibility.

Shareholder Advocacy

No company is perfect, and every company can improve to better address major ESG risks and opportunities. So, after we build a portfolio, we channel our clients’ investor voices to catalyze change.
