For many years, Domini has incorporated concerns about the environmental risks of companies owning and producing fossil fuels into our investment standards. Over time, we have gradually eliminated an increasing number of these firms from our holdings as our concerns about a variety of environmental and safety issues, including climate change, have increased.
We have never held coal-mining companies, and have historically approved very few major integrated oil companies. In recent years, we have excluded the few integrated oil companies that we had previously approved, and eliminated an increasing number of the smaller oil and gas companies from our list of eligible investments, due to concerns over safety or the environment.
We had historically favored companies focused on the production of natural gas because it burns more cleanly than oil. But as innovation took hold and hydraulic fracturing became widely used, we began to differentiate between the records of these natural gas companies. Due to increasing concerns about methane emissions, safety and community health issues, we gradually reduced the number of natural gas companies approved, until we divested from this segment of the energy industry entirely.
We exclude companies that are substantial owners and producers of oil or natural gas reserves and are included in the Integrated Oil & Gas or Oil & Gas Exploration & Production Industries as defined by the Global Industry Classification System (GICS), as well as companies significantly involved in coal mining.
We have made each of these decisions in light of the financial, environmental and moral 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 climate change, one of the most important and difficult issues of our time.
