Carbon Clean 200™

Investing in a clean energy future


Over the past years, a growing movement of investors representing trillions of dollars in assets under management have divested some portion of their fossil fuel investments. But where to invest this capital? The corollary of divesting fossil fuels is re-investing in the clean energy future. As an invitation to a larger discussion of how we can invest in this future, As You Sow and Corporate Knights created the Carbon Clean 200™ — a list of 200 publicly traded companies that are leading the way with solutions for the transition to clean energy.

The Clean200™ is intended as the clean energy inverse of the Carbon Underground 200™. Where the Carbon Underground 200™ (which evolved from the seminal Carbon Tracker Initiative report, Unburnable Carbon: Are the World’s Financial Markets Carrying a Carbon Bubble?), ranks the largest publicly listed companies by the carbon intensity of their coal, oil, and gas reserves; the Clean200™ ranks the largest publicly listed companies by their total clean energy revenues, with a few additional screens to help ensure the companies are indeed building the infrastructure and services needed for what Lester Brown and many others have called “The Great Energy Transition” in a just and equitable way.

2023 update

Just a few years ago, much of the business community viewed climate advocates with indifference or skepticism. Today, companies representing 40% of the global stock market have committed to science-based targets around reducing their greenhouse gas emissions in line with the Paris Agreement. In many cases, these businesses are already making billions of dollars supplying climate solutions to the market. Even corporations that are less directly implicated in the economic upside of climate action recognize the imperative for a low-carbon economy because no business can profit in an environment of climate chaos.

Yet, despite this reality being clear as day, we are plodding along on climate action. Worse, a handful of laggard companies and their pliant industry associations continue to advocate against climate action and for business as usual. The first thing we need to do is cut the poison that is at the heart of our climate breakdown.

That means finally cutting out the annual US$6 trillion in subsidies to fossil fuel companies that accounts for two-thirds of global greenhouse gas emissions.

It also means cutting off financing for new fossil fuel projects, which HSBC (one of the largest banks in the world) and Lloyds (the largest domestic bank in the U.K.) have done for new oil and gas fields – with some caveats.

And it means stopping all finance for activities that are killing our forests. Deforestation accounts for 11% of global greenhouse gas emissions, more than comes out of the tailpipes of all 1.4 billion cars on the world’s roads. If we went a step further than putting a stop to ripping out our forests and mangroves and started to restore them, we could get almost 40% of the way to our Paris Agreement goals by 2030.

But as former Bank of England (and Canada) governor Mark Carney has made clear, “the biggest threat to achieving 1.5 degrees is the speed at which we invest, not divest. We need at least $4 in clean energy investment for every $1 maintaining fossil fuels until we can phase them out by the end of this decade.”

The good news is that over the past decade, the flow of money into clean energy and efficiency infrastructure has tripled to about US$1 trillion annually. According to research from Bloomberg, global investments in clean energy transition reached US$1.1 trillion in 2022. This amount was roughly equal to the amount invested in fossil fuel production in the same year.

The Clean200™ lists the 200 major corporate players from 35 countries around the world that are at the forefront of this transition. These are the companies that are leading the way by putting sustainability at the heart of their products, services, business models and investments, helping to move the world onto a more sustainable trajectory.

This year’s Clean200™ companies rose to the top of a pool of 6,720 global firms based on rigorous assessment of the amount of revenue each company earns from products and services aligned with the Corporate Knights Sustainable Economy Taxonomy, while also ensuring that their businesses are not fundamentally offside important criteria for socially responsible investors, including being a company flagged by As You Sow’s Invest Your Values platform, which identifies fossil fuels, weapons, private prisons, thermal coal or having a record of systemically obstructing climate policy.

Key Findings

Geographically, the Americas and Europe account for 38.5% and 31.5% respectively of this year’s Clean200, while the remaining 60 companies are headquartered in the Asia Pacific region. The United States dominated the 2023 list, with 42 companies on the Clean200, while China had the second-largest share with 21, followed by Japan, which is headquarters to 16 Clean200™ companies.

On average, 58.3% of revenues earned by Clean200™ companies are classified as sustainable, representing close to $2.4 trillion in revenue, roughly unchanged from last year and significantly above the 5% average sustainable revenue for their MSCI ACWI peers.

Of note, it was found that on average, 44.4% of the capital expenditure, acquisitions, and research and development expenses among the Clean200™ companies were defined as sustainable by the Corporate Knights Sustainable Economy Taxonomy, compared to only 7% among MSCI ACWI constituents.

Of the 2023 Clean200™ companies, the Information Technology sector accounted for nearly a quarter of the total sustainable revenue at $586 billion, followed by the Communications Services sector ($542 billion) and the Industrials sector ($400 billion). On Sustainable Investments, the Utilities and Industrials sector led with $50 billion each, followed by the Communications Services sector at $24 billion in Sustainable Investments.

U.S. companies had, on average, the highest Sustainable Revenue at $23 billion. This is followed by Germany with $18 billion and South Korea at $17 billion.

But none of this would have legs if the Clean200™ weren’t also faring well financially. On this score, as of January 31, 2023, the Clean200™ outperformed its MSCI ACWI peers by 3.36% since the Clean200™ was launched in July of 2016. Clean200™ companies generated a total return of 91.21%, beating the MSCI ACWI broad market index (87.84%) and MSCI ACWI/Energy Index of fossil fuel companies (61.31%) on Total Return Gross — USD Basis from the Clean200™ inception of July 1, 2016, to January 31, 2023.

To put that in context: US$10,000 invested in the Clean200™ on July 1, 2016, would have grown to $19,121 by January 31, 2023, versus $18,784 for the MSCI ACWI broad market benchmark and $16,131 for the MSCI ACWI/Energy benchmark for fossil fuel companies.

Looking Ahead

This decade we need to move faster, quadrupling current levels of investment to the US$4 trillion annually (4% of global GDP) that is required, according to the International Energy Agency.

Finance ministers hold the keys to unlocking climate action. Fortunately, a new group, called the Coalition of Finance Ministers for Climate Action, from more than 80 countries, is looking to shift the view of climate action from a cost to a unique growth and investment opportunity. These finance ministers recognize that the current energy crisis and growing incidence of climate hazards are an opportunity for more, not less, action. And a rapid switch to renewable energy presents an opportunity for countries to deliver clean, cheap, secure energy and new employment at the same time.

Finance ministers globally manage huge annual budgets that collectively add up to around 30% of gross domestic product. Mobilizing 4% of global GDP for climate action is not going to happen without backing from heads of state, most critically those from the G20 countries. It is a tall task but one with precedent. It wasn’t that long ago that governments mobilized trillions of dollars to keep businesses and workers afloat during the early days of the COVID-19 pandemic.

Corporate Knights and As You Sow are pleased to present the latest edition of the Clean200™ to help investors identify the companies that are leading the charge on providing climate solutions while outperforming both the broad-based benchmark and its high-carbon global counterparts.

Clean200™ Methodology

The Clean200™ are the largest 200 public companies ranked by clean revenue. The ranking was first calculated on July 1, 2016, and publicly released on August 15, 2016, by Corporate Knights and As You Sow. The current list has been updated with data through January 31, 2023.

The Clean200™ companies are ranked by their clean revenues in U.S. dollars. The data set is developed through assessment of a company’s revenue that aligns with the definitions laid out in the Corporate Knights Sustainable Economy Taxonomy, primarily sourced from Corporate Knights research. To be eligible, a company must earn more than 10% of total revenues from clean sources.

The Clean200™ uses negative screens. It excludes all oil and gas companies, all utilities that generate less than 50% of their power from green sources, the top 100 coal companies measured by reserves, the top 100 oil and gas companies as measured by reserves, as well as all fossil fuel companies, majority fossil-fired utilities, pipeline and oil-field-services companies, and other fossil-fuel-related companies screened on As You Sow’s Fossil Free Funds. In addition, the Clean200™ excludes weapons companies, including major military arms manufacturers found on the Stockholm International Peace Research Institute (SIPRI) Top 100 arms-producing and military services list, as well as cluster munitions, nuclear weapons and civilian firearm manufacturers screened on As You Sow’s Weapon Free Funds. The Clean200™ also excludes palm oil, paper/pulp, rubber, timber, cattle and soy producers that are screened on As You Sow’s Deforestation Free Funds; companies that use child or forced labour, are involved in the manufacture of harmful pesticides, and that engage in negative climate lobbying are not included.
