Paris Agreement Article 6 Market Mechanism Explained: International Carbon Markets for NDC Achievement

What Is Paris Agreement Article 6: Legal Foundation for International Carbon Markets

The Paris Agreement, adopted in 2015, requires each country to voluntarily set and implement Nationally Determined Contributions (NDCs) to limit global average temperature rise to within 1.5 degrees Celsius above pre-industrial levels. The challenge is that NDC targets and abatement costs differ significantly across nations. The Article 6 market mechanism was designed to bridge this gap.

Article 6 provides a framework for reducing abatement costs and maximizing global emission reductions through international cooperation. Specifically, it consists of three pillars: Article 6.2 (bilateral cooperation), Article 6.4 (multilateral mechanism), and Article 6.8 (non-market approaches). Through COP26 (Glasgow, 2021), COP27 (Sharm el-Sheikh, 2022), COP28 (Dubai, 2023), and COP29 (Baku, 2024), detailed implementation guidelines were progressively finalized, reaching the historic milestone of the Article 6.4 carbon market's official launch in 2024.

The opening of international carbon markets means enormous business opportunities have emerged in developing countries with low abatement costs -- particularly Bangladesh, with its abundant renewable energy potential and existing climate cooperation agreements with Korea -- for generating carbon credits and utilizing them toward developed countries' NDC compliance.

Article 6.2 Bilateral Cooperation: Direct Country-to-Country Trading Structure

Article 6.2 is a voluntary bilateral cooperation framework between two countries (or a small group). Country A conducts greenhouse gas reduction projects in Country B and utilizes the resulting Internationally Transferred Mitigation Outcomes (ITMOs) toward Country A's NDC achievement. The core principle is "corresponding adjustment" -- to prevent double counting, Country B must deduct the transferred reduction volume from its own NDC.

Article 6.2 cooperation requires a bilateral agreement between the participating countries before ITMO transfer is possible. As of 2024, Korea has signed bilateral agreements or climate reduction MOUs with approximately 20 countries including Vietnam, Uzbekistan, Cambodia, and Bangladesh. Korea and Bangladesh officially signed a "GHG Reduction Project Cooperation MOU" in 2023, establishing the complete legal foundation for bilateral ITMO transfer. This 6.2 route is the fastest pathway for Korean companies to generate carbon credits through renewable energy and energy efficiency projects in Bangladesh and attribute them to Korea's NDC targets.

01
Bilateral Agreement: Establishing the Legal Foundation
Article 6.2 ITMO transfers must be preceded by an inter-governmental agreement. Agreements cover reduction sectors, corresponding adjustment procedures, MRV methodology standards, and dispute resolution mechanisms. The Korea-Bangladesh agreement covers energy, waste, and agriculture sectors, with Bangladesh's Department of Environment (DoE) and Korea's Ministry of Foreign Affairs Climate Change Division serving as joint secretariat.
02
Project Approval (LOA): Official Government Authorization
Each project requires official Letters of Approval (LOA) from both Country A (Korea) and Country B (Bangladesh) governments. Bangladesh's LOA is issued by the Department of Environment (DoE), typically requiring 6-12 months. Korea's Greenhouse Gas Inventory and Research Center (GIR) manages the ITMO registry and handles domestic approval.
03
MRV Execution: Measurement, Reporting, and Verification
Reduction results must undergo Measurement, Reporting, and Verification according to internationally recognized methodologies. Existing CDM methodologies (AMS-I.D solar, AM0015 biogas, etc.) may be applied, or new methodologies can be registered with the Article 6.4 Supervisory Body. Third-party verification organizations (TUV, DNV, SGS, etc.) conduct on-site verification and issue verification reports.
04
Corresponding Adjustment: Core of Double Counting Prevention
When Bangladesh transfers 10,000 tons of ITMOs to Korea, those 10,000 tons are deducted from Bangladesh's NDC accounting. This corresponding adjustment must be officially confirmed in writing by the Bangladesh government. Without this confirmation, Korea cannot count the credits toward its NDC. The bilateral agreement must codify the corresponding adjustment procedure to ensure legal completeness.
05
ITMO Registration and Utilization: Domestic Credit Integration
Verified reduction volumes are registered as ITMOs in Korea's GIR registry. Registered ITMOs can be directly attributed to the Korean government's NDC achievement, converted to offset credits under the domestic K-ETS (Emissions Trading Scheme), or used for corporate ESG purposes in the voluntary carbon market (VCM). The credit's market value varies by utilization pathway, making prior exit strategy development essential.

Article 6.4 Multilateral Mechanism: UN-Supervised International Carbon Market

Article 6.4 is a centralized international carbon market operated by an independent Supervisory Body (SB) under the UN. Designed as the successor to the CDM (Clean Development Mechanism), the decisive difference from 6.2 is that non-state actors including companies, NGOs, and local governments can directly register projects and receive official carbon credits called A6.4ERs (Article 6.4 Emission Reductions).

At COP29 in 2024, detailed operating rules for the 6.4 carbon market were finally agreed, and the SB began accepting project registration applications in earnest from 2025. The key strength of the 6.4 market is higher transparency and liquidity through standardized methodologies and a central registry, making it the structure preferred by global carbon investors. Bangladesh is preparing its Designated National Authority (DNA) to host 6.4 projects, with the first 6.4 project registration expected in 2025.

NDC Achievement Mechanism: How International Carbon Markets Fill Climate Targets

NDCs are emission reduction targets submitted by each country under the Paris Agreement on a five-year cycle. Korea targets a 40% reduction from 2018 levels by 2030, with up to 33.5 million tons CO2eq achievable through international reductions. Bangladesh has declared a conditional NDC of 43% reduction versus BAU by 2030, but achieving 43% without international financial support is challenging given its fiscal capacity limitations.

The international carbon market bridges these two countries' interests. Korea can procure reduction credits at far lower cost than domestically (domestic marginal abatement cost ~USD 50-100/tCO2 vs Bangladesh USD 5-15/tCO2), while Bangladesh receives foreign investment and technology transfer to upgrade its energy infrastructure. This "positive-sum" structure benefiting both countries is the design philosophy of the Article 6 carbon market.

Bangladesh Carbon Credit Market Opportunity Analysis

Bangladesh is one of the most watched emerging credit supply countries in the international carbon market. While energy demand is surging alongside annual economic growth above 7%, over 90% of power supply still depends on fossil fuels, creating massive reduction potential from renewable energy transition. According to SREDA estimates, Bangladesh's technical renewable energy potential exceeds 100GW for solar alone.

Notably, Bangladesh's RMG industry boasts the world's highest number of LEED-certified green factories (over 400), indicating established management capabilities experienced with rooftop solar, energy efficiency improvement project MRV infrastructure, and international auditing. Korean companies leveraging this foundation for carbon projects face significantly lower methodology application and verification risks compared to other developing countries.

Korean companies' competitive advantages in Bangladesh's carbon credit market stem from three sources. First, the Korea-Bangladesh bilateral agreement already provides the legal foundation for ITMO transfer. Second, public institutions such as KOICA, KEPCO, and Korea South-East Power have established local networks (BPDB, SREDA, Ministry of Industry) through pilot projects that private companies can leverage. Third, since Bangladesh's RMG industry is already a major supply chain partner for Korean companies, carbon projects can be naturally integrated into existing business relationships.

Practical Strategy: Carbon Project Entry Roadmap Using Article 6

There are two practical pathways for entering the Article 6 market. The first is the "government competitive project route" -- participating in Korean government international reduction project calls (jointly led by MOE, MOTIE, and MOFA) to receive government subsidies while generating Article 6.2 ITMO credits. The second is the "self-development route" -- independently or through a local JV partner, directly registering projects under the Article 6.4 mechanism. Both pathways can leverage the advantageous geographic conditions of Bangladesh and the Korea-Bangladesh agreement framework.

01
Phase 1: Pre-Feasibility Assessment (3-6 Months)
Analyze reduction potential, grid emission factors, and existing infrastructure in the planned investment area. Identify local partner candidates (factory owners, local governments, SREDA) through the KOTRA Dhaka Trade Office. Select applicable CDM or 6.4 methodologies and estimate preliminary reduction volumes and credit revenues. For the government competitive route, prepare feasibility study applications in advance of announcement dates.
02
Phase 2: Partnership Building and Project Structure Design (3-6 Months)
Execute a Joint Development Agreement (JDA) with local Bangladesh partners. Conduct preliminary consultations with SREDA and DoE on project objectives, and verify grid connection and permitting feasibility. Design project structure (direct investment, lease, energy service contract), credit revenue sharing ratios, and corresponding adjustment consultation channels. For the 6.4 route, prepare a Project Design Document (PDD) meeting UN SB registration requirements.
03
Phase 3: Government Approval and Financing (6-12 Months)
Simultaneously apply for LOA from Bangladesh DoE and Korea GIR. Arrange project financing during the approval period -- evaluate KEXIM green financing, GCF, ADB climate funds, and IFC blended finance. For government competitive projects, government subsidies are provided upon selection and agreement. Contract with MRV verification agencies (TUV, DNV, SGS, etc.).
04
Phase 4: Project Execution and MRV (2-5 Years)
Equipment procurement, installation, commissioning, and commercial operations commence. Prepare annual or biennial MRV monitoring reports and undergo third-party on-site verification. Submit ITMO credit issuance applications based on verified reduction volumes. Secure corresponding adjustment confirmation letters from the Bangladesh government.
05
Phase 5: Credit Utilization and Expansion (Ongoing)
Register issued ITMOs in the Korea GIR registry and select utilization pathway (government NDC attribution, K-ETS, VCM). Scale up based on initial project MRV track record and local networks, or replicate similar models in other regions. For 6.4 credits, direct sales on global carbon exchanges (XPANSIV, ACX, etc.) are also possible.

The Paris Agreement Article 6 international carbon market has now established itself as a new industry generating real business opportunities and asset value, transcending mere environmental policy discussions. The official launch of the Article 6.4 market in 2024 marked the turning point, and Bangladesh represents the strategic base where Korean companies can enter this new market under the most favorable conditions. Combining the legal foundation of the Korea-Bangladesh bilateral agreement, the local networks established by KOICA and KEPCO through pilot projects, and the RMG industry's green factory infrastructure, now is the optimal entry point for carbon credit market first-mover advantage. Companies that understand the Article 6 mechanism and act early will secure decisive competitive advantages in the carbon asset market over the next decade.
