As interest in fossil fuel free investing grows – today, the divestment movement represents over $3.4 trillion in assets under management – so do the number of financial products describing themselves as ‘fossil fuel free’.

But what does ‘fossil fuel free’ mean?

As the first family of responsible and diversified fossil fuel free funds, Green Century has been engaged in this conversation from the beginning. For us, and for many others in the fossil fuel divestment movement, investing fossil fuel free means excluding all companies that extract, explore, refine or process coal, oil or natural gas, as well as fossil fired utilities.

Girl in front of wind turbinesOther funds may not use the same definition. For example, some funds may say they are fossil fuel free, but invest in gas companies.

Other firms may describe a fund as ‘low carbon’, but there is no measurable definition for that term so it can be akin to using ‘natural’ for food to imply it’s organic, but it may not be.

But, there is a simple solution: read the prospectus of the fund. The prospectus should detail which types and how fossil fuel companies are excluded, as does Green Century’s, if a fund truly avoids coal, oil and gas companies.

P.S. – Green Century’s fossil fuel free definition goes beyond the divestment campaign’s ask of the top 100 coal and top 100 oil and gas companies as ranked by carbon reserves. We have found that most of the people who want to avoid the companies that caused climate change are not interested in investing in company #201 either!
