The data reveals a striking disconnect in corporate sustainability.
Between the end of 2023 and mid-2025, the number of companies setting validated science-based climate targets surged by 227 percent to over 10,000 organizations, representing over 40% of global market capitalization
Yet, during the exact same period, actual credit retirements in the voluntary carbon market (VCM) fell by 7% to 157 million metric tons.
On paper, corporate climate ambition is at an all-time high. In practice, the public funding of environmental projects on the ground is actively shrinking.
This gap is not occurring because companies have stopped purchasing carbon assets. It is because they have started executing their transactions in complete secret to avoid public and regulatory backlash.
The Operational Rise of the Anonymous Carbon Buyer
Corporate carbon procurement has transitioned from a public branding strategy to an undercover risk-management exercise.
A growing share of corporate buyers are deliberately concealing their market transactions.
Analysis from Carbon Direct shows that over 55% of spot market retirements over the past three years have been entirely anonymous, and the proportion is rising monthly.
The trend is even more pronounced in the high-durability carbon dioxide removal (CDR) sector, where nearly 40% of forward offtake transactions in 2025 did not disclose the buying entity.
Faced with a public environment where credit purchases invite intense scrutiny regardless of project quality, corporate legal and treasury departments are treating public disclosures as a liability rather than a marketing win. Anonymity has become the default mechanism for corporate risk management.
Yet, this silence hides a critical operational truth. Research shows that companies that actively purchase carbon credits are twice as likely to steadily reduce their own direct emissions and invest three times more in value-chain decarbonization than non-buying competitors. By going silent, corporate leaders are failing to defend a highly effective transition tool, leaving the market's narrative to be defined by its loudest critics.
The Greenhushing Regulatory Wall and the Death of Offsetting Claims
The transition to anonymous purchasing is being accelerated by a wave of strict global consumer protection regulations.
Historically, companies could buy low-cost forestry credits, claim "carbon neutrality," and print a green badge on their packaging.
That playbook is now illegal in major jurisdictions.
In the European Union, the impending Green Claims Directive and the Empowering Consumers Directive (set to take effect starting in September 2026) will ban generic "carbon neutral" marketing claims that are based purely on carbon offsetting. Non-compliance carries severe financial teeth, including potential fines of up to 4% of a company’s annual EU turnover.
Faced with the threat of multi-million-dollar fines and high-profile greenwashing lawsuits, risk officers are implementing "greenhushing" strategies.
They are continuing to buy high-integrity credits to meet internal risk targets, but they are completely scrubbing those transactions from their public marketing campaigns.
The market has fundamentally shifted: regulators now demand a strict separation between reducing your own direct emissions and funding external climate projects.
The 1:70 Squeeze on Permanent Removals
While the public spot market is going silent, the private forward-offtake market is experiencing unprecedented demand.
As corporate buyers realize that high-integrity, compliance-ready credits are in extremely short supply, they are moving away from transactional spot purchases.
According to Carbon Direct's 2026 market analysis, the ratio of high-durability spot retirements to committed forward offtakes stands at an astonishing 1:70. For every single tonne of engineered carbon removal retired today, corporate buyers have committed to purchase 70 tonnes for future delivery.
This forward-looking demand is driven by a looming regulatory bottleneck:
The SBTi removal mandate: Under the Net-Zero Standard Version 2.0, large companies will be required to utilize permanent carbon removals to neutralize their ongoing unabated emissions from 2035 onward.
Bilateral compliance demand: Compliance mechanisms like CORSIA and Singapore's bilateral carbon tax offset program are rapidly absorbing high-integrity credits that carry corresponding adjustments under Article 6 of the Paris Agreement.
Extreme supply constraints: Standard-setters like the ICVCM are enforcing rigorous quality baselines, ensuring that only a tiny fraction of global projects actually qualify for the premium Core Carbon Principles (CCP) label.
Because high-integrity removal capacity takes years to build, companies that delay their engagement face a structural supply squeeze. The silent buyers are not exiting the market; they are quietly locking up the high-integrity supply pipeline through 5-to-15-year forward offtake agreements.
Managing Carbon Under Mandatory Disclosure
Greenhushing is a short-term tactical retreat, not a viable long-term strategy.
While hiding your carbon credit purchases may protect you from immediate social media criticism, incoming regulatory frameworks will soon make carbon anonymity completely impossible.
Under the EU’s Corporate Sustainability Reporting Directive (CSRD) and the International Sustainability Standards Board (ISSB) frameworks, large companies must provide granular, audited disclosures on the exact origin, quality, and retirement status of all carbon credits utilized in their transition plans.
To protect your balance sheet and preserve your license to operate, your treasury and sustainability teams must:
Prepare for radical transparency: Assume that every anonymous transaction you execute today will eventually be made public under mandatory disclosure audits.
Map your portfolio to the highest standards: Anchor your carbon procurement on the ICVCM's Core Carbon Principles and secure credits that are strictly aligned with Article 6 corresponding adjustments to benefit from the widening quality-based pricing spread.
Transition to structured forward offtakes: Review your long-term liabilities and begin securing multi-year forward contracts for verified removals now.
In the next phase of the climate economy, the winners will not be the companies that hide their environmental assets in the dark. They will be the ones that build highly defensible, high-integrity portfolios that can withstand both public scrutiny and rigorous regulatory audits.
