ISO 14064 Details
What It Is
ISO 14064 is an international standard family (ISO 14064-1:2018, -2:2019, -3:2019) for greenhouse gas (GHG) quantification, reporting, and assurance. It provides a modular framework for organizations and projects, emphasizing principle-based approaches like boundary-setting and uncertainty management.
Key Components
- **Three partsPart 1 (organizational inventories), Part 2 (project reductions/removals), Part 3 (validation/verification).
- **Five principlesRelevance, completeness, consistency, transparency, accuracy.
- Scope 1-3 emissions classification, baselines, monitoring, risk-based assurance.
- No formal certification; relies on third-party verification statements.
Why Organizations Use It
Drives regulatory compliance (e.g., CSRD, SB-253), investor trust, carbon market access, and decarbonization strategy. Mitigates greenwashing risks, enables benchmarking, and unlocks green finance.
Implementation Overview
Phased approach: governance, boundary-setting, data collection, quantification, verification. Applies to all sizes/industries; 6-12 months typical, with software/tools and verifier engagement for audit-ready inventories.
CMMI Details
What It Is
Capability Maturity Model Integration (CMMI) is a performance improvement framework developed by the Software Engineering Institute and now governed by ISACA. It provides a structured approach to process institutionalization, focusing on maturity progression across development, services, and acquisition domains through staged or continuous representations.
Key Components
- 4 Category Areas (Doing, Managing, Enabling, Improving) with 12 Capability Areas and 25 Practice Areas in v2.0.
- Maturity Levels 0-5 and Capability Levels 0-3.
- Generic and specific practices for institutionalization.
- SCAMPI appraisals (Classes A/B/C) for benchmarking.
Why Organizations Use It
- Enhances predictability, reduces rework, improves quality.
- Meets contractual requirements in defense and regulated sectors.
- Mitigates operational risks via measurement and governance.
- Builds competitive edge through certified maturity ratings and stakeholder trust.
Implementation Overview
- Phased approach: assessment, piloting, rollout, appraisal.
- Involves gap analysis, training, tooling integration.
- Suits mid-to-large organizations in IT, software, aerospace.
- Requires authorized Lead Appraisers for formal ratings.
Key Differences
