Sustainable Investment Council

Leading our sustainable investing journey

The Sustainable Investment Council was established to facilitate our sustainable investing strategy, advance client-focused solutions, and bolster our expertise. With a dedicated chair and members who champion sustainable investing, we believe this structure helps us raise our own bar as we partner with clients to achieve their sustainable investing goals.

The Purpose: Results That Make a Difference

The Council focuses outward to hear what clients need and want in sustainable solutions and inward to advance our knowledge, align process, and move us forward.


Advancing Client Solutions

Portfolio managers connect with clients to better understand their needs. Hearing the voice of the client helps us focus on what they want to achieve.


Furthering Sustainable Efforts

The Council promotes best industry practices across our investment teams. Their leadership helps create alignment between our teams, processes, and sustainability efforts.


Expanding Our Expertise

Collaborating with our Sustainable Investing team is an important piece of the puzzle. The two groups work on training, accountability, and research topics to help expand expertise throughout our investing teams.


The Future

The Council focuses on initiatives that expand our sustainable investing knowledge, contribute to proprietary research and tools, and innovate client solutions.

Sustainable investing remains a strategic focus and firmwide commitment. We continue to add resources and adapt processes to optimally support this initiative.

Diversity, Equity and Inclusion

Many of American Century's investment strategies incorporate the consideration of environmental, social, and/or governance (ESG) factors into their investment processes in addition to traditional financial analysis. However, when doing so, the portfolio managers may not consider ESG factors with respect to every investment decision and, even when such factors are considered, they may conclude that other attributes of an investment outweigh ESG considerations when making decisions for the portfolio. The consideration of ESG factors may limit the investment opportunities available to a portfolio, and the portfolio may perform differently than those that do not incorporate ESG considerations. ESG data used by the portfolio managers often lacks standardization, consistency, and transparency, and for certain companies such data may not be available, complete, or accurate.

Sustainability focuses on meeting the needs of the present without compromising the ability of future generations to meet their needs. There are many different approaches to Sustainability, with motives varying from positive societal impact, to wanting to achieve competitive financial results, or both. Methods of sustainable investing include active share ownership, integration of ESG factors, thematic investing, impact investing and exclusion among others.
