# Overview for Carbon Buyers

### Overview

The Klima Protocol does not resell carbon credits. It facilitates the **retirement** of eligible credits. Retirement permanently consumes the environmental claim associated with a credit and cannot be reversed.

If you are seeking to compensate for emissions; whether for yourself, your organisation, or your customers, this section explains how to retire carbon credits using the Klima Protocol.

#### Functionality for Buyers

* Retire supported carbon credits at quoted, real-time execution terms.
* Receive a publicly verifiable proof-of-retirement certificate via Carbonmark.
* Associate beneficiary details (e.g. name, purpose of retirement).
* Select from supported carbon classes, vintages, and methodologies.

#### Important Limitations

* The protocol does not provide transferable credits. Only retirement is supported.
* Retirements are permanent and irreversible. Refunds are not possible once executed.
* Not all retirements include certificates from external registries. Some credits originate natively onchain (e.g. CMARK), while others may have been permanently removed from registries prior to protocol handling (e.g. UCR).

### Why Use Klima for Carbon Retirement?

Klima provides rules-based, onchain infrastructure designed to make carbon retirement accessible and operationally efficient.

#### Programmatic Settlement

Retirements execute via smart contracts without bilateral negotiation or manual reconciliation. Settlement is finalised onchain upon successful execution.

#### Continuous Execution Terms

The protocol applies transparent, rules-based mechanisms to service retirement demand across supported carbon classes. Execution terms update continuously based on observable supply and retirement activity.

#### Onchain Traceability

Protocol activity is recorded on a public blockchain. This provides a transparent and auditable record, from credit intake through retirement.
