Klima Protocol has released updated documentation for its Retirement Aggregator, a tool designed to help developers integrate carbon retirement functionality into their applications.
What it does:
- Acts as a data harmonizer for onchain carbon assets
- Streamlines and automates carbon integrations
- Provides standardized tooling for facilitating carbon retirements
Current usage: The aggregator has been adopted by various platforms over the past two years, including partner Carbonmark through their carbon retirement API. It has also been integrated into DEX platforms and blockchain-based marketplaces.
Why it matters: Klima's infrastructure serves as foundational tooling for builders in DeFi and the broader carbon market, enabling access to growing onchain carbon liquidity. The updated documentation aims to empower developers and market participants looking to build carbon-related applications.
Over the past two years Klima’s Retirement Aggregator tooling has been utilized by a variety of players in our space, including our partner Carbonmark via their carbon retirement API: docs.carbonmark.com. Additionally, it was previously used as part of a DEX integration for
Ultimately, Klima’s Retirement Aggregator acts as a data harmonizer for onchain carbon assets in order to streamline and automate carbon integrations in a secure fashion and help realize the aforementioned blockchain-enabled catalyzers of innovation.
Klima’s infrastructure is designed to serve as a foundational layer for other builders in our space, both across DeFi and the wider carbon market landscape. To that end, we have released an updated version of our Retirement Aggregator documentation to help empower other

Klima 2.0 Defines Five User Groups for Carbon Market Infrastructure
Klima 2.0 outlines five distinct participant categories for its carbon market infrastructure: **Carbon suppliers** (project developers and traders) receive a predictable, rules-based route to market with clear execution terms and no opaque spreads. **Carbon buyers** access verified retirements with transparent pricing. Credits cannot be resold—retirement is permanent, ensuring environmental claims remain auditable. **Coordinators** (kVCM and K2 participants) signal preferences that shape execution conditions within fixed bounds, enabling distributed decision-making without centralized control. **Liquidity providers** maintain continuous protocol access through open markets, ensuring reliable entry and exit without embedding carbon in automated market makers. **Builders and integrators** can develop against open-source smart contracts and APIs to embed carbon functionality into workflows. All groups operate under identical rules. The system aims to coordinate different interests without collapsing them into a single financial abstraction.
