Imagine an index fund of all of the publicly traded companies solving climate change.
This was our goal in building the Drawdown Index. We did not want to try and pick winners and losers (this solar company vs. that one). We wanted a way to invest in the entire ecosystem (or index) of climate change solutions.
Until now, the list of companies did not exist. If you wanted to invest in all of them, you would need to either build it yourself or hire an expensive investment manager to do it for you.
So we built one. In our climate friendly investment portfolios, we wanted to both divest them from fossil fuels and invest in the companies building climate solutions. Nobody had built the second part yet.
In this article, we’d like to walk you through how we build, update, and curate the Drawdown Index.
Project Drawdown is the leading resource on solutions to climate change. They have cataloged the top 100 climate solutions and lay out the: estimated cost to implement them, the potential financial savings, and the potential CO2e (carbon dioxide equivalent) avoided or sequestered.
What’s exciting about Project Drawdown is that these solutions aren’t science fiction. They are pretty much all technologies and practices that exist today and only require further scaling up.
From how we transport ourselves, to how we generate electricity, to how we grow and store our food — our global systems can become carbon neutral and even carbon negative if our civilizations invest in making it so.
While government policy is key towards advancing the climate solutions laid out in Project Drawdown, many of them are already being implemented and scaled up by private companies. From solar, to wind, to electric cars, to landfill methane capture, there are thousands of companies across the globe who are in the business of solving climate change.
While many of them are private companies, quite a few are publicly traded, meaning you can invest in them on public markets like the New York stock exchange. The problem we found was that outside of buying shares in them all individually, the only way to invest in these companies and support their mission has historically been to buy mutual funds or ETFs for a category of them, like solar or clean energy.
We like investing index funds because they often track all of the companies in given category of companies, without trying to pick winners and losers. This way you’re investing in the category itself. They generally have lower fees too. Until we built one, there was not an index of climate change companies. The closest you could get were solar and clean energy funds, but these only represent a fraction of the total companies solving climate change.
So we built and launched the Drawdown Index in 2020 with 112 companies solving climate change. Here’s the framework we use to decide which companies get included.
Historically, there are many frameworks that analysts use to assess companies on ethical grounds. Many of them result in a single score (ESG) or a letter grade (CDP). For some, this makes sense. The world is complex and there are truly hundreds of ethical lenses one can use to evaluate a massive company. Combining all of the answers into one score helps account for this complexity.
We’re ethically-driven investors who like to “look under the hood” of investment funds. And for us, we find these frameworks to be too opaque. We believe that in trying to capture and distill this ethical complexity, they often dilute the impact of key issues that we really care about, like climate change.
We took a simpler approach. In order for a company to be in the Drawdown Index, it needed to answer the following questions correctly:
Does the company make products or provide services that advance at least one of the climate solutions from Project Drawdown?
– If yes, then go to question #2.
– If no, then exclude.
Does the company make products or provide services for the fossil fuel industry?
– If no, then include.
– If yes: Would this company need to change its core business to adapt to a world without fossil fuels? Our test: Do they make more revenue from their drawdown solution or their sales to the fossil fuel industry?
– If yes, then exclude.
– If not, then include.
Question – Why would companies that make any products or provide any services for the fossil fuel industry be included in the index?
Answer – The world unfortunately still runs on fossil fuels. The process of Drawdown necessitates a transition away from fossil fuels. This transition will not happen overnight. We want to support the companies who are leading that transition while acknowledging that some of their customers may still be fossil fuel companies. Some examples:
There are dozens of investor-owned utilities traded on the New York stock exchange (such as Duke, Nextera, Dominion, Xcel, PG&E, etc.). While practically all of them have some form of carbon reduction/neutrality commitment, there is a broad range of historical investment in renewable energy and follow through on these commitments.
In order to be included in the Drawdown Index an investor-owned utility must:
Given these criteria it’s unsurprising that only four US-based utilities (Nextera, Exelon, and Ormat, and Avangrid) make the cut. We are excited for more utilities to hopefully be included in future iterations of the index as they progress towards carbon neutrality.
There are three Drawdown solutions related to waste management: recycling, composting, and landfill methane capture. All of the publicly traded waste management companies collect materials for recycling. Municipalities, not waste management companies decide to collect compost. Therefore, we opted to use the landfill methane capture as the deciding factor.
In order to be included in the Drawdown index a waste management company must capture methane at over 50% of the landfills it operates. Three out of the four publicly traded waste management companies meet this threshold.
If you look through the Drawdown list of climate solutions, you will find some solutions that don’t have in them. The publicly traded companies doing the work in these spaces have not passed criteria for inclusion. We hope this changes overtime. These solutions are exciting and we personally are excited to invest in them. Here’s some examples:
We did consider including a financial filter, but ultimately decided not to. Some of the companies in the index are very small, making them questionable investments for any sizable part of a portfolio. We have found that our portfolios avoid this problem. We base the amount invested in a Drawdown company based upon the size/value (market capitalization) of the company on the New York stock exchange.
So, the collection of micro cap companies in the Drawdown Index represented a proportionally micro portion of the overall portfolio allocation. They posed little actual liquidity risk. The only financial criterion for inclusion in the Drawdown Index is the stock must be traded on one of the New York Stock Exchange. Aside from that, the filter is purely ethical.
Did we miss companies in constructing the index? Most likely. This is V1. Every year we will conduct an annual review of the index, ensuring the companies we have included still meet criteria for inclusion and adding any new companies that have met the requirements for inclusion.
If you think we missed a company or we made a mistake including a company, please let us know at email@example.com so we can take your thoughts into consideration for next year’s update (we update annually because doing so more often could have negative tax consequences).
“Green” investing has had a historical stereotype of underperforming the rest of the market. So how did an investment strategy built around the Drawdown Index do?
We ran two simulations to look back and see what would have happened if you had invested in the Drawdown Index from 01/01/15 – September 1st, 2020 with annual updates at the end of each year. (Learn more about how we run simulations of historical performance our climate friendly stock portfolios)
Here you can see the results plotted against the S&P 500. The “CC – 100% stock (All green historical rebalancing)” represents a portfolio built only of companies in the Drawdown index. The CC – 100% (Annual rebalancing) represents the Carbon Collective equity portfolio of which the Drawdown Index makes up about 20%. They are both compared to the returns from the S&P 500 during the same time period (the orange line).
Please remember that past performance is no guarantee of future results.
What can we learn from this simulation? A few things that stand out:
The Drawdown index seemed to move in the same direction as the overall market, but with more volatility. This higher volatility is not surprising given the smaller number of holdings and lower diversity in the 100% Drawdown Index portfolio.
From an investment perspective, the stats show some positive indicators for the Drawdown Index (at least from during this time period). The time to recovery from its greatest loss is shorter than either of the two benchmarks and it significantly outperformed the expected return given the portfolio’s amount of risk (as evidenced by its high alpha).
Will this pattern continue? Who knows. Nobody can predict the future. What we can more confidently claim is that, at least over this time period, the stereotype of green investing underperforming the market did not prove to be true for this portfolio.
So that is how we compiled the first ever, exhaustive list of public companies solving climate change.
We began constructing the index because there was no comprehensive list of the publicly traded companies building climate change solutions. We sought to make the broad logic for inclusion and exclusion simple, clear, and algorithmic. For the companies where it would still be difficult to analyze whether they were “enough” focused on climate solutions, we included further criteria to define what is in and out.
We finished this year’s iteration knowing there were a number of Drawdown categories companies were working on, but still had not met criteria for inclusion in the full index. We’ll be updating it every year adding new companies that go public and old companies that shift their focus to solving climate change. We’ll also make sure to remove any companies that move backwards and no longer meet criteria.
