ESG Certification
ISO 14064-1 Certification – The ISO 14064-1 standard sets out the principles and requirements for designing and reporting organisational-level GHG (greenhouse gas) inventories by defining a specific policy for reducing emissions and achieving carbon neutrality.
To measure its GHG inventory, Open Fiber identified a baseline year (2022) against which to formulate its emissions reduction targets. The inventory comprehends all three scopes of the company’s emissions: specifically, direct emissions related to the vehicle fleet and heating systems, indirect emissions related to electricity consumption, and indirect emissions related to the value chain. The GHG emissions inventory is certified annually by an independent third party in accordance with ISO 14064-1.
