Calix Limited has released its first emissions reduction roadmap and updated its environmental monitoring practices, focusing on Scope 1 and 3 emissions. The company aims to measure, monitor, and reduce its direct emissions and indirect emissions across its value chain.
Material actions and disclosures
Calix’s FY25 GHG emissions inventory covers Scopes 1, 2, and 3 emissions, with Scope 1 accounting for approximately 12% of total emissions. Scope 3 emissions, which represent approximately 85% of the company’s greenhouse gas emissions, are primarily associated with purchased goods and services, capital goods, freight, and business travel.
Calix also updated its emissions-intensity metrics to better reflect current business activities. Emissions associated with the Magnesium Hydroxide Liquid (MHL) product are expressed in tCO2-e per tonne produced, while all other emissions are expressed as tCO2-e per dollar of non-MHL revenue.
Forward commitments
In FY26, Calix commenced development of an emissions reduction roadmap. The roadmap aims to address the significant portion of Scope 1 emissions arising from unavoidable process emissions from the calcination of carbonate materials like magnesite and limestone. Carbon capture and utilisation or storage (CCUS) is identified as the primary pathway to reduce these emissions.
Calix will continue to monitor emerging guidance and refine its approach as methodologies develop and carbon management infrastructure becomes available.
Calix remains committed to its decarbonisation efforts and the objectives of the Paris Agreement, supporting a transition to a low-carbon economy.
