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.

We have a long history of producing high‑performing, climate‑friendly materials and products, and of setting and achieving ambitious sustainability targets. We have demonstrated this again by bringing our 2030 carbon reduction targets forward to 2025. We have also established a carbon reduction roadmap, which is independently verified to be a science-based target (SBT) in line with the Paris Agreement objectives.


The 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.

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 lime kilns.

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.

Sustainable solutions for expanding cities

We are providing the building solutions needed for a net zero built environment. We are creating multiple high-quality, sustainable products and building solutions, like the curtain walls and composite doors manufactured and supplied by Oldcastle BuildingEnvelope®, part of our Building Products Division. These were used in the sustainable Watershed Building in Seattle, US.


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 target: 33% CO2 reduction to <520kg net CO2 / tonne cementitious product by 2025

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 2050 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.
