About our Report

Tarmac, a CRH company, is the UK’s leading sustainable building products, construction services and solutions business. Our innovative products, services and solutions help to deliver the infrastructure needed to grow the economy today and create a more sustainable built environment to support the future prosperity of the UK.

This report is based around our 2021 sustainability strategy, Act, and looks at improving sustainability for our business, our customers and communities by continually improving environmental, social and economic performance throughout the whole life cycle of our products, services and solutions.

At Tarmac, we are aligned with CRH and their new sustainability framework which identifies three rapidly emerging and hard to solve global challenges for the built environment and society - decarbonisation, waste and water. The world that we see emerging today is more complex than ever. With a rapidly growing population and cities already at capacity, climate change and demands on resources, there are significant challenges for the built environment and the infrastructure needed to support these expanding populations. We are investing our efforts to develop strong sustainability foundations around protecting the natural world, helping our people and communities to thrive and standing out as a responsible business.

Changes to our business in 2022

In 2022, our parent company, CRH, unveiled our new shared purpose – “We stand together to reinvent the way our world is built”. Our new values have been developed alongside our purpose to replace the Tarmac Way. As we redefined our purpose, we took the opportunity to refresh our values, pillars, and vision. These may look a little different, but they retain all of the underlying meaning of our original values – but we’ve made them bigger and more future-proof. CRH also set revised SBTi approved carbon reduction targets announced in early 2023.

This report has been prepared in accordance with the Global Reporting Initiative’s Sustainability Reporting Standards (GRI Standards). View the GRI Index.

It focuses on the issues that we consider to be material to our business as identified in our sustainability strategy.
