Which Sustainable Funds Are Fossil-Fuel-Free?

Morningstar research shows that despite the overall growth of sustainable funds, fossil-fuel-free funds still make up a small percentage of this universe.

On the whole, sustainable funds are on the rise, with a total of 303 funds as of the end of 2019 (up from 270 at the end of 2018). But these funds tend to have different definitions of what it means to be sustainable—they might focus on green bonds or invest specifically in renewable energy.

In the latest Sustainability Landscape report, we highlight a couple of types of sustainable funds that specifically contribute to climate action: fossil-fuel-free and low carbon. Here, we outline our findings on these categories.

A Look at Fossil-Fuel-Free Funds

Funds define fossil-fuel free differently. For example, three State Street ETFs use the term “Fossil Fuel Reserves Free” in their names. These funds exclude companies that own “proved and probable coal, oil, and/or natural gas reserves used for energy purposes,” but they still have overall fossil-fuel exposure ranging from 4.3% to 7.4%.

From Morningstar’s perspective, fossil-fuel involvement is defined more broadly as a portfolio’s percentage exposure to companies that derive at least 5% of their revenue from thermal-coal extraction, thermal-coal power generation, oil and gas production, or oil and gas power generation, or 50% of their revenue from oil and gas products and services.

By this definition, only a few sustainable funds avoid investing in fossil fuels altogether. By prospectus, just 91 of the 303 sustainable funds say they are fossil-fuel-free or even low carbon. And when we apply our definition of fossil-fuel involvement to the portfolios of diversified sustainable equity funds, only 10% are not involved.

Across the diversified U.S., non-U.S., and global-equity sustainable equity funds, we found:

  • 16 funds had no fossil-fuel involvement in their most recent portfolio.
  • 11 funds had less than 1% fossil-fuel involvement.
  • 35 funds had 7.5%-10% fossil-fuel involvement.
  • 8 funds had more than 10% fossil-fuel involvement.

The table below lists the funds on both sides of this spectrum: the 16 without fossil-fuel involvement and the eight with more than 10% fossil-fuel involvement.


Another measure of funds’ fossil-fuel involvement is the Morningstar® Low Carbon Designation, which is given to funds that have lower-than-average fossil-fuel involvement (but not necessarily complete avoidance) and low levels of carbon risk, which is the risk to companies in a portfolio of financial impacts in the transition away from fossil fuel. Of the 303 funds available at the end of 2019, 98 received the Morningstar Low Carbon Designation.

When it comes to exposure to thermal coal—considered the fossil fuel with the worst carbon impact—sustainable funds have higher levels of avoidance:

  • 47 funds had no thermal-coal exposure.
  • 26 funds had less than 1% thermal-coal exposure.
  • 34 funds had 3%-5% thermal-coal exposure.
  • 9 funds had more than 5% thermal-coal exposure.

Avoiding Fossil-Fuel Involvement Requires a Closer Look

Just as investors have their own takes on what it means to invest sustainably, so too do funds. Investors should know that they won’t necessarily be avoiding fossil-fuel involvement completely by simply putting their money in sustainable funds—or even in funds that use the phrasing fossil-fuel free in their names.

To ensure avoidance of fossil fuels and investments in low-carbon options, investors should take care to evaluate funds using additional criteria such as our fossil-fuel involvement measure and the Morningstar Low Carbon Designation.
