The ISO Technical Committees classification provides access to standards organized by the expert groups responsible for their development and maintenance. Technical Committees (TCs) and their Subcommittees (SCs) are the operational bodies within the International Organization for Standardization (ISO) where subject matter experts, industry representatives, and national standards bodies collaborate to develop international standards in specific technical domains.

The RCGI.OS database includes carefully selected ISO Technical Committees particularly relevant to low-carbon technologies, climate action, and sustainable development. These currently include ISO/TC 301 (Energy management and energy savings), ISO/TC 207/SC 7 (Greenhouse gas and climate change management and related activities), ISO/TC 207/SC 5 (Life cycle assessment), and ISO/TC 265 (Carbon dioxide capture, transportation, and geological storage). Additionally, the database covers emerging sustainability domains including ISO/TC 255 (Biogas), ISO/TC 300 (Solid recovered materials, including solid recovered fuels), ISO/TC 297 (Waste collection and transportation management), ISO/TC 323 (Circular economy), and ISO/TC 331 (Biodiversity).

By filtering standards through Technical Committees, users can explore the complete portfolio of standardization work developed by specific expert groups, understand the technical scope and boundaries of standardization efforts, track ongoing developments within domains, and identify gaps or opportunities for new standardization initiatives. This classification is especially valuable for researchers and practitioners seeking to engage with standardization processes, contribute technical expertise, or understand the governance structure behind international standards.
