What is Carbon Registry India?

CR-I is a standards-based voluntary carbon crediting programme set up by NCCF in 2021. It registers climate mitigation projects and issues Marketable Carbon Units (MCUs) for verified reductions and removals.

About NCCF

The Network for Certification and Conservation of Forests (NCCF) is an Indian not-for-profit society that develops sustainability standards. It created and manages CR-I.

How CR-I is governed

The Governing Council gives final approval on registrations, issuances and methodologies. An Administrative Structure runs daily operations, advised by an Advisory Board and a Methodology Panel.

Who does what

CR-I has five kinds of participant: NCCF as the regulator, Independent Project Proponents (IPPs), Validation and Verification Bodies (VVBs), Independent Methodology Developers (IMDs) and Transactional Organisations (TOs).

Marketable Carbon Units (MCUs)

An MCU is the unit of exchange in CR-I. One MCU represents one verified and certified metric tonne of carbon dioxide equivalent (tCO2e) reduced or removed.

Scope: sectors, gases and geography

CR-I accepts projects anywhere in the world, covers the six Kyoto Protocol greenhouse gases, and uses the sectoral scopes of the UN Clean Development Mechanism.

Principles and avoiding double counting

CR-I applies six GHG accounting principles from ISO 14064-2, and a set of controls so that each tonne is counted and claimed only once.

Glossary of key terms

Short definitions of the terms used across CR-I documents, from additionality to vintage, based on the CR-I Glossary of Terms.

The 17 UN Sustainable Development Goals, with SDG 13 Climate Action highlighted. Every CR-I project contributes to at least four SDGs, including SDG 13.
