# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
