How Sequoia Is Rebuilding the Carbon Credit Market on a Foundation of Radical Verification

The Dirty Secret Behind Carbon Offsets

Every year, corporations spend billions of dollars on carbon credits to meet their net-zero commitments. Fortune 500 sustainability teams sign off on offset portfolios. ESG reports get published. And somewhere, in a rainforest or a degraded field or a nascent direct air capture plant, a project is supposed to be pulling carbon out of the atmosphere on their behalf.

Except — in a staggering number of cases — it isn't. A landmark 2023 investigation found that over 90% of rainforest offset credits certified by the world's largest registry were largely worthless, representing no real carbon reduction. Projects over-count removals. Permanence is assumed, not measured. And brokers sitting between buyers and developers extract margins as high as 40%, while the projects doing genuinely difficult removal science struggle to find buyers willing to pay a fair price.

The voluntary carbon market had a trust problem long before that headline. It has always relied on a patchwork of registry self-certification, inconsistent methodologies, and the uncomfortable reality that verifying carbon removal — especially over the decades-long timescales that matter climatically — is genuinely hard. So the market settled for proxies. For intentions. For hope.

Sequoia was built on the premise that hope is not a verification strategy.

What Sequoia Does

Sequoia is a verified carbon credit marketplace — but that description undersells what the platform actually represents. It's a complete rearchitecting of how carbon credits are measured, issued, priced, and traded.

The company's tagline says it plainly: The marketplace where every carbon credit tells a verifiable story. That story isn't a PDF methodology document. It's a continuous, multi-layered evidence stream: satellite imagery captured on a regular cadence, IoT sensor data from the project site, and AI models that don't just verify that carbon was captured — but model the probability that it stays captured for 100, 500, and 1,000 years.

This is Sequoia's Permanence Score — a proprietary metric that transforms an opaque, binary credit into a nuanced, time-weighted instrument. A biochar project with a 1,000-year permanence profile is fundamentally different from a forest protection project with significant reversal risk. Sequoia's scoring makes that difference legible, and lets buyers pay accordingly.

Every project listed on the marketplace goes through Sequoia's verification stack before a single credit is issued:

• Multispectral satellite monitoring — continuous observation of project sites, detecting changes in biomass, land use, or project integrity that would be invisible to annual audits
• Independent field audits — third-party boots-on-the-ground verification at project initiation and on a recurring schedule
• IoT sensor networks — real-time measurement of soil carbon, emissions, and environmental conditions where applicable
• AI permanence modeling — machine learning trained on thousands of project outcomes to predict reversal risk across multiple time horizons

Registry standards don't disappear — Sequoia layers its own verification on top of existing certifications, catching what those standards miss and providing the additional signal that sophisticated buyers increasingly demand.

Two Constituencies the Market Has Always Failed

Sequoia is explicit about serving two groups — and equally explicit that the current market fails both of them.

For Buyers

Corporate sustainability teams facing regulatory scrutiny under frameworks like the SEC's climate disclosure rules or the EU's Corporate Sustainability Reporting Directive can no longer afford reputational risk from low-quality offsets. The days of buying cheap avoidance credits and calling it net-zero are ending. Sequoia gives compliance teams the audit trail they need: transparent methodology, continuous monitoring data, and a Permanence Score they can defend to regulators, investors, and the press.

Beyond corporations, Sequoia serves individuals who want their offsets to actually matter — a market that has been systematically underserved by opaque, broker-mediated purchasing experiences.

For Project Developers

This is where Sequoia's mission feels most urgent. Direct air capture plants, enhanced weathering operations, biochar producers — the projects doing the hardest, most permanent carbon removal work — currently compete on price with forest protection projects that cost a fraction as much. The market can't distinguish quality, so it defaults to cheap.

Sequoia's verification stack creates a quality signal that commands a premium. When buyers can see exactly what they're getting — and trust that signal — developers running high-quality, high-permanence projects can charge prices that reflect their true cost and impact. That economic signal, in turn, drives more capital toward the removal approaches the climate actually needs.

The Market Opportunity

The voluntary carbon market is at an inflection point. Scrutiny from journalists, NGOs, and regulators has cratered confidence in low-quality credits — but the underlying demand is only growing. Companies need credible offsets. The gap between that demand and a trustworthy supply is exactly the market Sequoia is building into.

Regulatory tailwinds are accelerating the timeline. The SEC's climate disclosure requirements, CSRD in Europe, and the Integrity Council for the Voluntary Carbon Market's Core Carbon Principles are collectively raising the floor for what constitutes an acceptable credit. Sequoia's verification stack doesn't just meet that floor — it defines the ceiling.

Why Sequoia Stands Apart

The carbon market has no shortage of marketplaces. What it has always lacked is verifiable truth. Sequoia's differentiation isn't a feature — it's an epistemological commitment. The platform refuses to issue a credit it cannot independently verify, and it refuses to describe permanence in terms it cannot quantify.

That commitment creates compounding advantages:

1. Regulatory moat: As disclosure requirements tighten globally, Sequoia's verification standard becomes the default definition of a credible offset.
2. Developer network effects: High-quality project developers migrate to the platform where they can charge quality-commensurate prices, raising the average quality of listed inventory.
3. Buyer trust flywheel: Verified credits attract scrutinous enterprise buyers, which drives volume, which funds deeper verification infrastructure.
4. Data asset: Every project monitored adds to Sequoia's training data for permanence modeling — a dataset that becomes more valuable and more accurate with every credit issued.

Built with AI, Built to Last

Sequoia was conceived and launched on Artha, the AI platform that takes a company from a single prompt to a fully operational business. The speed at which Artha enables founders to go from mission-driven insight to live product meant that Sequoia's team could focus their energy where it mattered most — on the verification science and the developer relationships that define the platform's real value.

That AI-first foundation isn't just about launch velocity. Sequoia's permanence scoring models, satellite data pipelines, and risk assessment infrastructure are deeply computational by nature. Building on a platform designed to leverage AI from day one gave Sequoia a structural advantage in developing the algorithmic backbone that makes its verification stack possible.

You can explore the live platform at sequoia-earth.tryartha.com.

What's Next for Sequoia

The near-term roadmap centers on three priorities: expanding the verified project portfolio across removal technology categories, deepening integrations with corporate sustainability reporting workflows, and extending the permanence modeling capability with additional satellite data sources and longer historical training sets.

Longer term, Sequoia's verification infrastructure has the potential to become the measurement layer that the entire voluntary carbon market runs on — not just credits traded on its own marketplace, but a standard that third-party registries and compliance markets can license and build on. The platform that defines what verification means in carbon markets is a platform with an extraordinarily durable competitive position.

The climate math is unambiguous: we need high-quality carbon removal at scale. The economic infrastructure to fund that removal depends entirely on buyers being able to trust what they purchase. Sequoia is building the trust layer that makes that infrastructure possible.
