Secure a carbon removal offtake at today’s price
Secure future carbon removal supply from the most sought-after projects on the market. Lock in your price today and pay in full on delivery.
A contract built for your CFO
No deposit
You pay nothing when you sign. Payment is due as each year’s verified carbon removals are delivered.
Fixed price
The price you agree today stays the same for every delivery year, regardless of market changes.
Repurchase
If your emissions forecast falls, Senken repurchases delivered credits before retirement, so you do not have to keep volumes you no longer need.
The best projects sell years in advance
Carbon removal projects take time to build, and buyers often secure their output years before delivery. Much of the high-quality supply expected by 2030 is already contracted, particularly for durable removals.
An offtake agreement secures your share of future supply.
