Exclusionary Screens

The capital markets are highly effective mechanisms for raising funds for a wide variety of products and services, but we do not want to invest in products that have the potential to cause incalculable harm. We therefore exclude corporations substantially involved in weapons and civilian firearms production and nuclear weapons production, as well as the owners of nuclear power plants. The dangers of weapons of mass destruction and the international arms trade are among the greatest we face today, and we view the spread of nuclear power technology as tied to the proliferation of nuclear weapons, in addition to presenting significant risks to human health and the environment.

We exclude companies in the energy sector involved in oil and natural gas exploration and production, coal mining, oil and gas storage, transportation, refining, and related service providers. We have made this decision considering the financial, environmental and human health concerns associated with fossil fuels and in recognition that an increasing portion of the responsible investment community has found divestment a productive avenue to further debate on this, one of the most important and difficult issues of our time. 

We also do not invest in companies that are significant manufacturers of alcoholic beverages or tobacco, or significant providers of  gambling goods and services. For these companies, effective marketing often means exploiting customers' addictions to these products or ignorance of their risks. This is not a business model we believe our investors wish to support. 

In addition to these industry exclusions, we have generally avoided for-profit companies substantially involved in the operations of prisons, as well as major producers of synthetic pesticides and agricultural chemicals. This is due to significant civil and human rights and environmental concerns, respectively, related to these two businesses.
