The Case
On 14 January 2020, Larry Fink published his annual letter to CEOs. The title was “A Fundamental Reshaping of Finance.” The core argument was precise: climate risk is investment risk, and because climate change is going to reshape the economy over coming decades, it will reshape the value of every asset class. BlackRock, Fink declared, would put sustainability at the centre of its investment approach.
The letter set out concrete commitments. BlackRock would exit investments in companies that generated more than 25% of revenues from thermal coal production. It would launch new investment products that screened out fossil fuels. It would demand that companies report in line with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD) and the Sustainability Accounting Standards Board (SASB). Climate risk would become a standard factor in portfolio construction and risk management across the firm.
The reaction was immediate. Because BlackRock managed approximately $7 trillion in assets, its declaration that climate is a financial risk was not a niche investor position. It was, effectively, a signal to every CEO and CFO in every major market that the world’s largest asset manager was now evaluating their companies through a climate lens. Capital would follow conviction.
The following year, BlackRock supported Engine No. 1’s activist campaign against ExxonMobil, a direct application of its stated climate governance principles. The period from 2020 to 2021 represented the high-water mark of mainstream financial institutions treating climate as a defining investment question.
The tide then shifted. In 2022, BlackRock announced it would support fewer climate-related shareholder resolutions, stating some were not consistent with clients’ long-term financial interests. A Morningstar analysis found BlackRock voted against 80% of key climate resolutions. Republican-led US states began withdrawing public pension funds from BlackRock over what they characterised as politically motivated ESG investing, withdrawing an estimated $4 billion in 2022 alone. In June 2023, Fink told an interviewer he was “ashamed” of the term ESG and would stop using it.
The letter’s legacy is therefore double-edged. It normalised climate as a financial variable in a way that no single document had done before. It also showed how quickly that normalisation can be contested when it encounters political resistance.

- Jan 2020 BlackRock client letter announces exit from thermal coal producers and launch of fossil-fuel-screened products
- May 2021 BlackRock votes in favour of Engine No. 1's board nominees at ExxonMobil, the most visible application of its stated climate governance stance
- 2022 BlackRock signals retreat: announces it will support fewer climate resolutions; Republican states begin withdrawing public funds in protest at ESG approach
- Jun 2023 Fink publicly distances himself from the term ESG, citing political weaponisation of the label by both left and right
The Debate
The central question the BlackRock letter raises is whether a passive fund manager can be a credible climate actor. A passive fund, by definition, tracks an index. It holds shares in the companies that are in the index, including the largest fossil fuel producers, and it cannot sell those positions without ceasing to be passive. BlackRock’s actual influence over portfolio companies therefore runs through voting and engagement, not capital allocation. Critics argue this is structurally insufficient: you cannot simultaneously be one of the world’s largest investors in an industry and credibly threaten to withdraw capital from it.
Defenders of BlackRock’s approach argue this misunderstands how large asset managers operate. Passive ownership is permanent ownership, which creates genuinely long-term interests in systemic stability. A passive fund cannot sell ExxonMobil, but it can vote against its board, support activist campaigns, and refuse to back management compensation linked to carbon-intensive growth. Used consistently, these tools have real force, as the Engine No. 1 case showed.
The retreat from ESG language in 2023 raises a harder question: was the 2020 letter a genuine strategic reorientation, or a positioning move that proved difficult to sustain under political pressure? The underlying financial logic, that climate risk is investment risk, has not changed. What changed was the political cost of saying so publicly in certain markets. Whether that distinction matters depends on whether you think financial markets are ultimately governed by logic or by politics.
