Climate Change


Protect climate through entire value chain

The 21st century will be defined by the challenge of climate change, in which the construction sector can play a key role. For LafargeHolcim, this global challenge requires a collaborative response that goes beyond our ambitious efforts in own operations. The Group is committed to reducing CO2 emissions across the entire construction value chain.

LafargeHolcim is committed to actions across the entire construction chain to minimize environmental impact and maximize value creation.

As the most advanced group in its sector, LafargeHolcim’s approach is to generate, monitor, and report greenhouse gas savings right through to the use of its solutions through their life cycle.

Contributing to energy efficiency of buildings

Today, buildings consume 90% of their total energy usage through heating, lighting and air-conditioning (source: International Energy Agency). Existing technologies, including cement and concrete-based solutions, can reduce this energy consumption by 60-80%.

LafargeHolcim has developed a number of solutions to improve energy efficiency in buildings, such as:

  • low carbon cements, such as Solidia™, Optimo, Aether® cements, and a range of low clinker content cements,


  • recycled aggregates, such as Aggneo™ high-quality recycled aggregates and services,


  • high performance insulating concretes, such as Thermedia®, Ecoterm®, and


  • efficient building systems.

Reducing emissions in our manufacturing process, including indirect emissions

LafargeHolcim constantly works to reduce energy consumption and CO2 emissions at all stages of its production process, wherever it is feasible and economically viable:

  • Improving process mastery, including increased energy efficiency and capturing as well as recycling thermal energy back into the process.  


  • Continuous reduction of clinker in cement accordingly to customers‘ requirements, by incorporating carbon-neutral mineral components such as pozzolana, blast furnace slag, or bottom fly ash from the power industry.


  • Sourcing electricity from renewable sources, such as wind, solar, or biomass, to reduce CO2 emissions linked to power generation.


  • Reducing emissions related to product and materials transportation through the increased use of rail and water and by improving efficiency of the truck fleet.

Advocacy and promoting responsible climate and energy policies

Advocacy is becoming increasingly important, to encourage energy efficiency and innovation across the value chain. Through day-to-day contacts with authorities, issuance of policy papers, and participation in associations, LafargeHolcim supports policies that promote:

  • a meaningful price on carbon,


  • the progressive creation of a level playing field between local production and imports,


  • the predictability of the legal framework, which supports investment in long-term carbon solutions.


Our senior leadership team is also fully engaged in advocacy:

  • LafargeHolcim’s co-Chairman Bruno Lafont is co-chair of Energy Efficiency in Buildings 2 (EEB2) – phase 2 of a project that aims to transform the building sector to achieve a 60% reduction in energy use by 2050. He is also Chairman of the European Round Table of Industrialists (ERT) Energy and Climate Change Working Group, and he sits on the Executive Committee of the World Business Council for Sustainable Development (WBCSD).


  • LafargeHolcim, through its legacy companies, is a co-founder of the Cement Sustainability Initiative (CSI).
