Klima 2.0 serves distinct participants across carbon, reflecting the different roles required to operate shared market infrastructure. Its design recognises that carbon markets can work only when different actors can coordinate without distortion. Core user groups: 1/ Carbon suppliers (project developers & traders) - A predictable, rules-based route to market for eligible credits. - No bespoke negotiations. No opaque spreads. Clear execution terms. - Intent: lower friction and uncertainty for those bringing real supply. 2/ Carbon buyers (retirerees) - Direct access to verified carbon retirements with transparent pricing and provenance. - No secondary trading. No reuse. Retirement is the terminal action. - Intent: ensure environmental claims credible and auditable. 3/ Coordinators (kVCM & K2 participants) - Participants who signal preferences that shape execution conditions and system capacity, within fixed bounds. - Intent: harness distributed knowledge without discretionary control. 4/ Liquidity providers - Enable continuous access to the protocol’s functions via open markets. - Intent: ensure reliable entry and exit without embedding carbon in AMMs. 5/ Builders & integrators - Developers can integrate against open-source smart contracts and APIs to embed carbon functionality into real workflows. - Intent: treat Klima as shared infrastructure, not a closed platform. Whilst these different user groups may have different roles in Klima, they are all subject to the same rules. Success means coordinating these disparate interests, not to collapsing them into a single financial abstraction.
