Much has been made of whether and how the stock market can meaningfully support climate action. Because most transactions occur in the secondary market, trading shares of listed companies appears rather removed from the "real" economy, where tangible decarbonization takes place.
While greenhouse gas emissions reduction is more traceable with a venture capital (VC) investment in a climate solutions company or a bank loan for a climate-friendly project or product, the stock market is not a neutral bystander in the climate crisis.
Publicly traded companies continue to prop up the fossil fuel and deforestation industries by providing a means to make money from injustice. For example, in the first two weeks after the 2022 invasion of Ukraine, the prices of oil, coal and gas increased by roughly 40 percent, 130 percent and 180 percent in Europe, respectively; this enabled fossil fuel stock market investors to benefit from the appreciation of stock prices and potentially higher dividends.
On the climate positive side, the existence of the stock market increases the number and quality of climate solutions companies. Because VC investors look forward to exit events, whereby they liquidate their equity position in a startup to achieve returns, the initial public offering (IPO) is one of the main ways to attract such investors. The absence of a stock market would therefore limit the universe of new climate companies, as fewer VC funds would be willing to invest in climate startups.
Stock exchanges also increase the opportunities for climate solutions to scale by building capital in IPOs and signaling to other forms of capital, such as bank lending, that companies are creditworthy. This is why facilitating capital formation, one of the three core mandates of the Securities and Exchange Commission (SEC), is vital for climate action.
Beyond the NYSE
Carbon Collective, an investment product developer and asset manager that allows retirement accounts, brokerage accounts and trusts to invest in climate-friendly stock and bond portfolios, created the Carbon Collective Climate Solutions U.S. Equities ETF. The underlying research to create the exchange-traded fund uses the Project Drawdown solution list and is publicly available and searchable via a database. In total, the U.S. climate stock list has 186 companies that pass an exclusionary filter, meaning that the companies generate at least half of their revenue from climate solutions, and 129 pure-play climate companies. The existence of such an ETF, and the fact that the universe of investable opportunities is rich, indicates the role that the U.S. market can play in scaling climate solutions.
The trouble is most people are not U.S.-based, and most economic activity takes place outside of the U.S. If the world is to sufficiently invest in a viable planet, investors and lenders must back climate solutions companies globally, notably where most people live — in the Global South, also known as the Global Majority.
In its recent database update, Carbon Collective added climate companies listed in the Global Majority. Although not yet covering the entire world, the climate solutions stocks database now includes three additional regions: the African Union (AU), the Association of Southeast Asian Nations (ASEAN) and the Community of Latin American and Caribbean States (CELAC). These economic zones represent $3 trillion, $3.3 trillion, and $7 trillion in annual GDP, respectively and in total represent a population of 2.7 billion.

Bridging the geographical divide
Companies listed on the AU, ASEAN and CELAC stock exchanges total 1,034, 3,373, and 1,611, respectively; in the U.S., there is a universe o
