Sibelco’s Climate & Energy report sets out the group’s decarbonisation strategy, targets and performance through March 2026. The company says its near-term targets for Scope 1, 2 and 3 emissions have been validated by the Science Based Targets initiative and aligned with the Paris Agreement. It reiterates a commitment to cut Scope 1 and 2 emissions intensity by 5% a year from 2021 to 2030, while investing about €90 million between 2022 and 2030 in technology and operational improvements.

The document explains how Sibelco intends to meet those goals. Its programme combines energy efficiency, renewable electricity, fuel switching, electrification, process redesign and customer- and supplier-engagement measures. Governance is organised around a CO2 Steering Committee and a Core Team, while managers’ annual bonuses are tied to energy and greenhouse-gas reduction targets. The report also highlights employee training, ISO 50001 energy audits, internal carbon pricing and external verification, including a limited assurance audit by EY covering 2021 to 2025 data.

The KPI section shows a clear decline in emissions versus the adjusted 2021 baseline. Scope 1 emissions fell from 302,736 tCO2e in 2021 to 236,803 tCO2e in 2025. Market-based Scope 2 emissions dropped from 237,263 to 201,304 tCO2e, while total energy consumption decreased from 2,237,242 MWh to 1,862,526 MWh. The company’s Scope 1 and 2 financial intensity improved from 0.36 to 0.23 kg CO2e per euro of ex-works revenue. Total gross Scope 3 emissions also declined, from 11.77 million to 8.20 million tCO2e, although supplier and customer engagement with science-based targets reached only 25% by 2025 against a 2026 objective of 68.9%.

Sibelco also underlines the role of its products in the low-carbon transition. It points to its European glass recycling activities, which process more than 3 million tonnes of waste glass a year, and to product development linked to circularity and carbon removal, including enhanced rock weathering. The report notes that some recent emissions improvements were helped by portfolio and volume effects that may not recur, and says the company’s CO2 strategy will undergo a full review in 2026.
