ContactHolding companies and corporate groups face a version of sustainability complexity that no single-entity framework was designed to solve. Subsidiary companies operate in different sectors, face different regulatory obligations, and produce data in different systems. CDP disclosure may be required at group level — driven by investor expectations across the portfolio. CSRD may apply to a European operating company. Consolidated GHG reporting is required at the group level — across a portfolio of entities with different emission profiles, different ERP systems, and different data maturity levels.
The organizations that manage this most effectively are those that establish a group-level sustainability architecture from the top down — defining the consolidation methodology, the data governance structure, and the disclosure framework before individual subsidiaries begin building in isolation. That is the work Semtrio is built for.
Trusted by Holding & Group Leaders
Consolidated GHG accounting for a holding company requires more than aggregating subsidiary emissions. Group consolidation methodology — operational control, financial control, or equity share — must be selected, justified, and applied consistently across entities in different jurisdictions, sectors, and ownership structures. Subsidiaries in CBAM-covered sectors require embedded carbon calculations. EU-operating subsidiaries may be in CSRD scope independently of the group. And the group-level sustainability disclosure must reflect all of this coherently to investors, regulators, and ratings agencies — without the inconsistencies that arise when each entity builds its own reporting system separately.
IFRS S2 is increasingly requiring holding companies with listed parent entities to disclose climate-related financial risks at the group level — covering the combined physical and transition risk exposure across the entire portfolio of subsidiaries. SBTi target setting for holding companies requires a portfolio-level approach: understanding the emissions profile across subsidiaries, identifying where decarbonization potential is greatest, and setting targets that are both ambitious and operationally credible across a diverse group structure. CDP assessments at group level are increasingly driven by investor expectations — institutional shareholders in diversified holding companies are requesting CDP disclosure as a portfolio-level governance signal, not just a single-entity climate metric. EcoVadis evaluations increasingly cover holding company structures — requiring the group to demonstrate that sustainability governance extends across its portfolio, not just at the centre.
Holding company sustainability obligations arrive at both the group and subsidiary level — often under different frameworks at once. Each service below addresses a specific pressure point.
We have delivered consolidated sustainability systems for eight of Turkey's largest corporate groups — across manufacturing, energy, finance, and consumer sectors simultaneously.

Sectors served across Semtrio's portfolio
Manufacturing, energy, finance, retail, aviation, construction materials, telecoms — all within single group engagements
Multi-entity sustainability advisory requires a capability that most specialist firms do not have — the ability to hold the full regulatory picture across different sectors simultaneously, and design a consolidation architecture that serves all of them from a single group-level data structure. Semtrio has delivered Consolidated GHG Accounting projects for eight of Turkey's largest corporate groups — organizations with subsidiaries spanning manufacturing, energy, finance, retail, and aviation within a single group structure. That cross-sector depth is what makes the methodology transferable: the steel subsidiary, the energy arm, and the retail portfolio can all be served by the same team applying the same methodological consistency.
Our delivery across 10+ sectors means that when a holding company's portfolio spans industries, we do not need to learn the regulatory landscape of each subsidiary from scratch. We already know it — because we are already advising individual companies within those sectors on the same frameworks.
Whether you're consolidating GHG data across subsidiaries, scoping CSRD and CDP obligations across a diversified portfolio, or building the group-level framework that ties it together — we're here.
