# II-AMT: International Initiative for Development of Article 6 Methodology Tools

Published by Perspectives Climate Group. Canonical page: https://perspectives.cc/initiatives/iiamt/

An open initiative developing the methodological tools that Article 6 cooperation needs in practice: additionality determination, baseline setting and beyond.

- Started: 2021
- Field: Carbon Markets · Policy
- Participants: Governments, standards and market practitioners
- Status: completed
- Supported by: African Development Bank Group (AfDB), Federal Ministry for Economic Affairs and Climate Action of Germany (now the Federal Ministry for the Environment, Climate Action, Nature Conservation and Nuclear Safety of Germany), Institute for Global Environmental Strategies (IGES), Japan Ministry of the Environment, Swedish Energy Agency (SEA), Department for Energy Security and Net Zero (UK Government)

## Overview

The International Initiative for Development of Article 6 Methodology Tools (II-AMT) was an international expert-led process designed to align existing baseline and monitoring methodologies with the rules and principles of Article 6 of the Paris Agreement. The initiative was active between 2021 and 2025, prior to the full operationalisation of the Paris Agreement Crediting Mechanism (PACM). Experts involved included methodology experts from various continents, combining regional climate policy and practice.

Under this initiative, a set of Article 6 methodology tools, covering additionality determination, baseline setting, and MRV, were developed to be added to existing methodologies in a modular fashion.

The initiative went through three phases: conceptualisation, development, and piloting.

## Background & rationale

The decision accompanying the Paris Agreement emphasises that international cooperation under Articles 6.2 and 6.4 should build on lessons learnt from the Kyoto Mechanisms, including the Clean Development Mechanism (CDM). However, as CDM methodologies were developed under the Kyoto Protocol, they do not take into account host countries' Nationally Determined Contribution (NDC) targets, existing mitigation policies, or the need to align mitigation action with the Paris Agreement's long-term goal. Developing entirely new methodologies from scratch would be a costly and time-intensive process. To address this challenge, II-AMT worked to modularise Article 6 requirements, enabling their rapid application to existing methodologies.

## What we did

Perspectives Climate Research convened an international expert team to design, develop and test the Article 6 methodology tools. All three phases were completed. Throughout the phases, the experts provided methodological input to inform the operationalisation of the PACM, drawing on insights from the tools' development and testing.

The expert team included Axel Michaelowa (Perspectives Climate Research, Switzerland), Derik Broekhoff (Stockholm Environment Institute, US), Francois Sammut (Carbon Limits, Norway), Jessica Wade-Murphy (Atmosphere Alternative, Colombia), Martha Ntabadde Kasozi (freelance consultant and member of the CDM methodologies panel, Uganda), Paula Macias Diaz (Carbon Limits, Norway), Randall Spalding-Fecher (Carbon Limits, Norway) and Sina Wartmann (independent consultant for MRV and Transparency, Germany).

## Timeline

- Phase I (Conceptualisation): Framing the Article 6 requirements that existing methodologies need to satisfy, and how to modularise them.
- Phase II (Development): Drafting the additionality, baseline and MRV tools as modular additions to existing methodologies.
- Phase III (Piloting): Testing the tools against real carbon market activities to refine their robustness and usability.
