From 2035, SBTi V2 makes carbon removals mandatory.
The supply doesn't exist yet.
The price won't wait.
Almost every SBTi-committed company must neutralize residual emissions with carbon removal. The 2035 Reserve lets you secure that supply now, at today's price, and pay on delivery.

Trusted by sustainability leaders
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 rising durable-removal requirement, scaling to 100% by your net-zero year.
€71€169/t
Price locked at signing
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.
100%
Pay on delivery
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.
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 durable-removal tech SBTi V2 actually requires the most locked-up of all.

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 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.
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.
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.
Only the top 5% of credits go into your 2035 Reserve.
Senken's SII scores every project against 600+ data points across additionality, permanence, leakage, monitoring, co-benefits, and policy alignment. The portfolio is built from ICVCM CCP-approved methodologies, with a durable removal share rising to 100% by your net-zero year.

Answers to the four questions every CFO asks.
The 2035 start date and the durable-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.
