CRH is a global leader in sustainable building materials and a significant contributor to the circular economy. As we transition to a net zero society, we continue to evolve our business strategy to address the growing demand for sustainable products and building solutions to reduce the impact of construction on our world.

To protect our climate, the world needs to deliver absolute emission reductions. We are proud to have the most ambitious absolute emissions reduction target for 2030 in our sector. This complements our 2050 carbon reduction roadmap, which is aligned with the goals of the Paris Agreement.


Our roadmap includes plans to:

  • Increase the use of alternative raw materials to reduce the carbon intensity and quantity of clinker in cement
  • Replace carbon‑intensive fossil fuels with biomass and alternative fuels
  • Invest in renewable energy
  • Improve operational eco‑efficiency
  • Work collaboratively to develop the technologies, strategies and policies needed across our industry

Driving actions for carbon neutrality

As the leading building materials business in the world, we recognise our responsibility to develop innovative solutions that can help our industry play its part in the drive to carbon neutrality by 2050.

Improving energy efficiencies

Jura Materials, part of our Europe Materials Division, is enhancing its energy efficiency by optimising geothermal power generation. The Organic Rankine Cycle (ORC) Plant at its Wildegg location recovers waste heat that can be used as a power source. This valuable process results in electricity savings of 20% in its cement operations annually.

Innovating for a net-zero future

We are developing the technologies needed to further increase the contribution of our products to a net-zero, built environment. At our Innovation Centre for Sustainable Construction, our research and development team is working to maximise the potential of concrete to contribute to a sustainable built environment through carbon emissions uptake, recyclability, thermal properties and other mechanisms.

Finding new sources of low-carbon energy

We are working with partners along the value chain to explore the potential for new alternatives to fossil fuels, such as hydrogen, biomass and low-carbon electricity. For example, we are piloting the use of dried micro-algae as a zero-carbon alternative fuel in cement and line kilns.


Our objectives and targets

Our ambition: To address climate change as we strive for carbon neutrality along the cement and concrete value chain by 2050

Our targets:
25% absolute reduction in Scope 1 and 2 GHG emissions by 2030
33% CO2 reduction to 520kg net CO2 / tonne cementitious product by 2025

CRH has had its emissions reduction targets approved by the SBTi as consistent with levels required to meet the goals of the Paris Agreement.

We have also joined the Business Ambition for 1.5°C initiative, which aims to achieve net-zero global emissions by no later than 2050 in order to limit global warming to 1.5°C.

Our actions and progress

2020 CO2 emissions: Scope 1 – 32.4m tonnes, Scope 2 – 2.6m tonnes, Scope 3 – 10.9m tonnes

Our 2020 progress:

  • Exceeded our 2020 CO2 specific net emission reduction commitment with a reduction to 573 kg CO2/tonne of cementitious product
  • 51% of fuel requirements in our cement plants in the European Union were provided by alternative fuel
  • 94% of total product delivered in 2020 was by operating companies that have transport initiatives in place

Our ambitions

To achieve our ambition of carbon neutrality, we are embracing multiple breakthrough technologies, as well as ongoing continuous improvements across our operations.

Carbon capture, decarbonation, use of concrete as a carbon sink and identifying new sources of alternative fuels and materials continue to be priorities in our innovation programme. Through these and other innovations we are working to shape a more sustainable built environment.


The target boundary includes biogenic emissions and removals from bioenergy feedstocks.
