Market for durable carbon credits

TAM // TOTAL ADDRESSABLE MARKET

$0B

SAM // SERVICEABLE ADDRESSABLE MARKET

Low confidence

$1.1B to $2.4B

SOM 3YR // SERVICEABLE OBTAINABLE MARKET

$0M

Real and growing market, but the integrity wedge is already claimed

The durable carbon credit market is genuine and expanding, but your likely pitch, that quality verification and permanence are the wedge, is exactly the position Pachama (absorbed into Carbon Direct with $88M raised and 800+ clients) and Sylvera already occupy. South Pole commands project supply across 850+ projects, and Climeworks owns the DAC offtake narrative with Microsoft and Morgan Stanley signed up. Your single weakest link is not demand or TAM; it is that every serious buyer already has a vetted counterparty, and switching costs are high once multi-year offtake contracts are signed. The 84% high-risk finding from Max Planck will not drive buyers to you if incumbents can cite the same research first.

Key risk

Corporate buyers with multi-year DAC offtake contracts have no switching incentive for a new entrant.

TAM // TOTAL ADDRESSABLE MARKET

$16B

Voluntary carbon credit market only, $4B in 2024 growing at 35% CAGR; durable credits are a premium subset, not the compliance behemoth.

SAM // SERVICEABLE ADDRESSABLE MARKET

Low confidence

$1.1B to $2.4B

stated: $2.4B

High-integrity, durable-removal credits (biochar, DAC, enhanced weathering) represent roughly 15% of voluntary market today, skewed toward corporate net-zero buyers.

Top-down yields $2.4B; bottom-up on verified durable-credit buyers yields $1.1B, a 2.2x gap driven by thin buyer-count data.

SOM 3YR // SERVICEABLE OBTAINABLE MARKET

$36M

Year 3 target of roughly 200 corporate buyers at $180K average annual spend, implying 1.5% SAM share after a sub-0.5% year-one entry.

>Methodology

TAM TOP-DOWN

The compliance carbon market ($887B in 2025, per Grand View Research) is dominated 98.6% by regulated ETS permits that a durable-credit marketplace cannot touch. The honest TAM is the voluntary carbon credit market: $4.04B in 2024 per Grand View Research, growing at 35.1% CAGR. Projecting two years forward at that rate yields roughly $7.4B by 2026.

$4.04B x 1.351^2 x 0.40 premium-segment share = ~$3B single-year; $16B cumulative 2025-2030 TAM ceiling

TAM BOTTOM-UP

6,500 companies participated in voluntary carbon markets in 2024 (carboncredits.com). Durable removal credits are a premium niche; conservatively 8% of those buyers, or 520 companies, are willing to pay for permanence at scale today. MSCI 2025 data puts high-rated credit pricing at $14.80/ton average; DAC and biochar range $105 to $1,000/ton per Senken. Using a blended durable-credit price of $150/ton and a median annual purchase of 10,000 tCO2e per qualifying corporate buyer yields $1.5M per buyer per year. 520 buyers at $1.5M equals $780M annually.

520 buyers x 10,000 tCO2e x $150/ton = $780M; x3 global pipeline multiplier = ~$2.3B

SAM FILTERS

Filter 1: Durable removal only (biochar, DAC, enhanced weathering), not avoided-emission credits. Rationale: the startup's value proposition is permanence; avoidance credits are legacy product. Applied at 15% of voluntary market by current volume, rising. Filter 2: Buyers with active net-zero science-based targets, 6,200 companies globally per Mordor Intelligence, narrowed to the 42% of Fortune Global 500 with carbon-credit commitments, roughly 840 large corporates. Filter 3: Geography excludes compliance-only ETS markets (88.68% Europe share is compliance-dominated). SAM = 15% segment share of the $16B TAM envelope.

$16B TAM x 0.15 durable-segment share = $2.4B SAM top-down; 520 buyers x $1.5M x 1.4 growth factor = $1.1B bottom-up

SOM BUILD

Year 1: 30 corporate clients signed at $120K average annual spend (blended 800 tCO2e at $150/ton), equaling $3.6M, or 0.15% of SAM. Realistic given Pachama's 800-client base took multiple funding rounds to reach. Year 2: 80 clients at $150K average = $12M (0.5% SAM). Year 3: 200 clients at $180K average = $36M (1.5% SAM). Headwinds: 84% of credits flagged high-risk (Max Planck) will prompt buyer caution on new platforms; Pachama/Carbon Direct and Sylvera already offer integrity screening, compressing new-entrant pricing power.

Year 3: 200 clients x $180K avg spend = $36M = 1.5% of $2.4B SAM

Competitors // Threat map

NameFundingPositioningThreat
VerraNon-profit standards body; self-sustaining via registry feesLargest issuer of voluntary carbon credits globally, 1,800+ projects, 295M VCUs issued in 2021 alone; de facto certification standard.Controls the trust infrastructure; any durable-credit marketplace must work with or around Verra's registry, giving Verra permanent gatekeeping leverage.
Pachama / Carbon Direct$88.2M raised across 6 rounds; acquired by Carbon Direct November 2025AI and remote-sensing verification of forest and nature-based carbon; 800+ clients including Microsoft, Salesforce, Airbnb; only 30% of registry projects pass its integrity screen.Direct incumbent in integrity-screening, already enterprise-contracted; acquisition by Carbon Direct deepens capital and advisory integration.
South Pole GroupPrivate; largest carbon project developer globally850+ projects across 6 continents; full-service developer, broker, and advisor; commands supply-side relationships new entrants cannot replicate quickly.Controls project supply pipeline; a new marketplace without South Pole inventory is structurally disadvantaged on both sides of the transaction.
ClimeworksRaised over $800M including $650M Series C (2022)Direct air capture at scale; Mammoth plant online May 2024; multi-year offtake signed with Microsoft, Morgan Stanley; commands $450-$1,000/ton pricing.Owns the DAC permanence narrative and the anchor buyer relationships; defines the premium end of the durable-credit market a new entrant wants to serve.
Gold StandardNon-profit; WWF-foundedPremium certification emphasizing SDG co-benefits and community impact; 44M credits issued; automatic credibility with ESG-conscious buyers.Provides a competing quality signal for buyers skeptical of Verra; reduces differentiation for any platform claiming superior credit integrity.
