ISO 50100:2026

Overview

ISO 50100:2026 is an international standard developed by ISO that establishes requirements and provides comprehensive guidance to organizations on reducing energy-related greenhouse gas emissions (ERGE). The document is geared toward helping businesses and institutions of any type, size, or sector achieve decarbonization objectives, covering both direct (Scope 1) and indirect (Scope 2) emissions resulting from energy consumption. ISO 50100:2026 supports transparent target-setting, robust planning, and demonstrable achievement of absolute reductions in ERGE, aligning with organization-specific decarbonization strategies and global climate action imperatives.

This standard integrates seamlessly with existing energy management systems (EMS), such as ISO 50001:2018, and supports organizations in developing effective decarbonization pathways in line with global frameworks like the Paris Agreement and Nationally Determined Contributions (NDCs).

Key Topics

• ERGE Quantification and Reduction: The standard details systematic methods for quantifying both Scope 1 and Scope 2 energy-related GHG emissions, emphasizing accurate data collection, the selection of relevant GHG emission factors, and robust calculation or direct measurement approaches.
• Boundary Definition: Clear guidance on establishing physical or organizational boundaries for decarbonization, ensuring all relevant energy-related emissions within the organization’s control are included.
• Leadership Commitment: Top management must demonstrate ongoing commitment by supporting strategic decarbonization planning, allocating necessary resources, and integrating ERGE targets into overall business strategy.
• Decarbonization Planning: Step-by-step requirements for developing, implementing, and updating decarbonization action plans, including establishing base years, setting interim and long-term targets, and ensuring actions lead to measurable ERGE reductions.
• Monitoring and Reporting: Rigorous processes for ongoing monitoring of ERGE reductions, data quality, and transparent reporting, enabling organizations to validate and verify claims regarding their decarbonization achievements.
• Stakeholder Engagement: Emphasis on communication and involvement of both internal and external interested parties in planning, decision-making, and review processes.
• Compatibility and Integration: Designed for compatibility with existing GHG protocols and standards. ISO 50100:2026 can be used alongside or integrated within an established EMS for greater effectiveness and repeatability.

Applications

ISO 50100:2026 is applicable to any organization seeking to:

• Reduce Carbon Footprint: Establish and achieve measurable reductions in energy-related GHG emissions as part of a broader sustainability or corporate social responsibility (CSR) strategy.
• Comply with Regulatory Requirements: Demonstrate conformity with national or international decarbonization regulations, industry norms, or voluntary commitments.
• Improve Operational Efficiency: Identify opportunities for energy efficiency, technology upgrades, and process improvements that contribute to reduced energy consumption and lower emissions.
• Enhance Transparency and Credibility: Provide stakeholders and regulators with evidence of a structured, credible approach to decarbonization, supporting claims regarding ERGE targets and performance.
• Support Net Zero and Carbon Neutral Goals: Lay the groundwork for alignment with net zero or carbon neutrality pathways, using established frameworks for ERGE reductions.
