Due to its shared security model, Polkadot is uniquely positioned to utilize existing network activity to natively power a carbon sink.

Transaction fees currently being used as an anti-spam mechanism can be leveraged to make every transaction on Polkadot carbon negative, without requiring any changes to the user experience. With the widespread adoption of Sequester across its growing ecosystem, Polkadot has the potential to be one of the largest carbon-offsetting entities worldwide.

To enable this future, we are building Sequester — a package that automates the functionality of aggregating transaction fees, exchanging them into carbon-backed tokens, and retiring underlying carbon offsets that meet the community’s specifications.
