The Offset Mechanism Under CCTS – A Complete Guide for Project Developers and Non-Obligated Entities
Introduction: The Voluntary Pathway to Carbon Credits
India's Carbon Credit Trading Scheme (CCTS) is not just for obligated entities. The scheme also includes an Offset Mechanism—a voluntary, project-based system designed for non-obligated entities to register their projects aimed at reducing, removing, or avoiding GHG emissions.
The offset mechanism was introduced in an amendment to CCTS dated 19 December 2023. Through the offset mechanism, non-obligated entities can register activities that lead to GHG emission reductions, avoidance, or removals for issuance of carbon credit certificates.
The procedure elaborates a structured project cycle that begins with pre- and post-account registration on the India Carbon Market (ICM) portal, and progresses through stages like developing the project design document (PDD), and validation, monitoring, and issuing of carbon credit certificates (CCCs).
For non-obligated entities—whether renewable energy developers, forestry project owners, agriculture project developers, or waste management companies—the offset mechanism offers a clear pathway to generate tradable carbon credits.
This guide provides a comprehensive overview of the offset mechanism under CCTS, the project cycle, approved methodologies, and how to participate.
What Is the Offset Mechanism?
Definition
The Offset Mechanism is a voluntary mechanism under the CCTS where Non-Obligated Entities (Non-OEs) can register their projects for accounting GHG emission reduction or removal or avoidance for issuance of Carbon Credit Certificates (CCCs).
Purpose
The offset mechanism aims to incentivise voluntary actions from entities not covered under compliance for GHG reduction, thus providing a comprehensive approach to decarbonisation of the economy.
Key Characteristics
| Characteristic | Description |
|---|---|
| Participation | Voluntary |
| Participants | Non-Obligated Entities (Non-OEs) |
| Mechanism Type | Project-based, baseline-and-credit (ex-post) |
| Credits | Carbon Credit Certificates (CCCs) |
| GHG Coverage | All GHGs relevant to the approved methodology |
| MRV Approach | Project-specific, baseline-additionality |
The Regulatory Framework
The Detailed Procedure for Offset Mechanism under CCTS (Version I) was released in March 2025. It elaborates a structured project cycle that begins with pre- and post-account registration on the ICM portal, and progresses through stages like developing the PDD, and validation, monitoring, and issuing of CCCs.
Who Can Participate in the Offset Mechanism?
Eligible Participants
| Entity Type | Examples |
|---|---|
| Renewable Energy Developers | Solar, wind, hydro, biomass projects |
| Forestry Projects | Afforestation, reforestation, mangrove restoration |
| Agriculture Projects | Soil carbon, regenerative farming, rice cultivation |
| Waste Management | Biogas, landfill methane capture, waste-to-energy |
| Industrial Efficiency | Energy efficiency improvements |
| Technology-Based Removal | Biochar, Enhanced Rock Weathering |
| Any Organisation | Any entity with an eligible project |
Eligibility Criteria
| Requirement | Description |
|---|---|
| Entity Registration | Register on the ICM Portal |
| Methodology | Use a BEE-approved methodology |
| Project Validation | Have the project validated by an accredited verification agency |
| Verification | Have emission reductions verified by an accredited verification agency |
| Registry Account | Open a Registry account with the Grid Controller of India |
What Non-Obligated Entities Need to Know
- You do not need a compliance target to participate
- You can generate CCCs from eligible projects
- You can sell CCCs to obligated entities or voluntary buyers
- You must follow the same methodology and verification requirements as compliance projects
- Your CCCs are fungible with compliance credits
The Offset Mechanism vs. The Compliance Mechanism
Structural Differences
| Aspect | Compliance Mechanism | Offset Mechanism |
|---|---|---|
| Concept | Obligated Entities comply with GHG intensity targets | Non-Obligated Entities register activities that lead to GHG reductions |
| Type | Mandated, target-based | Voluntary, project-based |
| What Drives Crediting | Overperformance vs. emission intensity trajectory | Project-level GHG reductions vs. baseline |
| Participants | OEs only | Non-OEs only |
| MRV Approach | Gate-to-gate boundary, intensity-based | Project-specific, baseline-additionality |
| GHG Coverage | CO₂ and PFCs | All GHGs relevant to the approved methodology |
The Fungibility Principle
CCCs are defined uniformly across both markets, without distinction between compliance and offset certificates. This means CCCs generated under the offset mechanism can be used for compliance purposes, creating a single, integrated carbon market.
Why This Matters
The integration of compliance and offset markets:
- Enhances liquidity
- Improves price discovery
- Creates opportunities for non-obligated entities
- Supports compliance for obligated entities
