2035 Reserve

From 2035, SBTi V2 makes carbon removals mandatory.
The supply doesn't exist yet.
The price won't wait.

Every SBTi-committed company must compensate up to 100% of residual emissions, with 41% from permanent removals. The 2035 Reserve lets you secure that supply now, at today's price, and pay on delivery.

How it works

Reserve your 2035–2045 audit-grade supply at today's price.

A multi-year contract for audit-grade carbon removals delivered each year from 2035 to 2045. Senken builds a vetted portfolio that meets SBTi V2's 41% permanent-removal requirement at your net-zero year.

  • Direct air capture
  • BECCS
  • Enhanced rock weathering
  • Nature-based removal
  • Price locked at signing

    €71/t

    Locked today

    €169/t

    2045 open market

    Fixed today, for delivery anywhere from 2035 to 2045, while the open-market price is projected to reach €169/t by 2045 (BloombergNEF). That gap is your saving.

  • Pay on delivery

    100%

    Pay 100% on delivery: nothing leaves your books until each year's tonnes are verified and retired, so your capital stays free to fund your own decarbonization. An optional 15% deposit locks today's €71/t.

  • Flexible repurchase

    If your emissions forecast changes, sell delivered tonnes back to Senken before retirement, so you're never locked into volume you no longer need.

The supply constraint

Why 2035 is too late to start buying.

Durable removals are tiny today and almost entirely pre-sold. Only about 1 Mt has ever been delivered, and by 2030 most of the audit-grade pipeline is already spoken for, with the long-lived tech SBTi V2 actually requires the most locked-up of all.

Senken supply tracker, May 2026. Long-lived tech (DAC, BECCS, ERW) is the binding constraint for SBTi V2 compliance.

  • 78.5%

    of every durable removal tonne ever contracted is held by Microsoft alone, the only buyer to sign a single deal over 1 Mt

  • ~2%

    of all contracted durable supply has actually been delivered. The rest is years of promised volume, not tonnes on the market today

  • 6.5 Mt

    of high-durability removal demand by 2030 (McKinsey): several times today's output, and climbing toward your net-zero year

The only way to control your 2035 position is to contract it now.

The price argument

Today is the cheapest day to buy.

BloombergNEF's Removal scenario has audit-grade removal at around €71/t today, peaking at €133 in 2030, climbing again to €181 by 2040, and settling at €169 by 2045. A 2.38x trajectory between now and your net-zero year. Today, you can fix €71/t for delivery anywhere from 2035 to 2045.

The case for your CFO

The contract your CFO already knows how to sign.

You pay 100% on delivery. No capital upfront: every euro leaves your books only as each year's tonnes are verified and retired. Prefer today's lowest price? An optional 15% deposit locks €71/t. Either way, at any reasonable cost of capital the contract holds a positive NPV, the same structure your finance team already signs for long-term energy.

  1. The default

    100%

    Paid on delivery.

    Zero deposit. Every euro leaves your books only as that year's tonnes are verified and retired into your account. Your capital stays free to fund your own decarbonization, with nothing at risk before the impact is delivered.

  2. Optional

    15%

    Deposit to lock the lowest price.

    Want today's €71/t fixed across all eleven delivery years? A 15% deposit at signing secures your slots and waives the small pay-on-delivery premium. The remaining 85% is still paid on delivery.

Bring this to your CFO

Answers to the four questions every CFO asks.

What if SBTi V2 changes between this release and later revisions?
The 2035 start date and the permanent-removal requirement are structural design choices in the standard, locked in direction even if specific percentages move at the margin. A 2035 Reserve built on rolling vintages, multiple registries, and multiple methodologies survives any plausible future revision. The position that does not survive is buying nothing.
What if a project methodology we're contracted into gets invalidated later?
Your contract is structured around audit-grade categories, not specific project tags. If a methodology in your portfolio is downgraded, Senken substitutes equivalent tonnes from inside our vetted pipeline at no additional cost to you. Concentration limits prevent any single methodology from carrying more than its contracted share.
What if our residual forecast changes? Could we end up over-buying?
Tonnes you return to Senken before retirement never enter your ESRS E1-7 disclosure. Tonnes already retired stay retired. You can sell delivered tonnes back at market price minus a small fee, and the Reserve is sized to your worst-case residual, not your central forecast.
Why not just wait and buy on the spot market in 2035?
Three reasons. First, the supply will not be available at the volume you need: 78.5% of all durable carbon removal ever contracted is already Microsoft's, only ~1 Mt has ever been delivered, and the realistically un-contracted pool is just a few million tonnes globally. Second, today's price (€71) is projected to roughly double by 2045 (€169). Third, ESRS E1-7 and ISSA 5000 reward forward contractual agreements with a deeper audit trail than spot purchases can provide.
