In its 2012 Sustainability Report, CRH states that it ‘ has progressed and developed in all areas of sustainability and sought to ensure that the key elements are embedded in our business model.’
CRH has operated successfully for over forty years. This success has been based on a solid foundation and commitment to fundamental aspects of business – strong customer and supplier relationships, value added products, efficient processes and targeted markets, balanced across both sectoral and geographic areas. These fundamentals of business are managed within a strong framework and focus on health & safety, environment & climate change, people & community and corporate governance. In all of these areas, CRH sets policies, implements management systems, monitors performance and incorporates stakeholder feedback at each stage aiming for continuous improvement across its activities. By developing sustainable businesses, CRH aims to remain an industry leader creating long term value for all stakeholders.
In 2007, CRH, in fulfilling its obligations as a member of the Cement Sustainability Initiative, publicly committed to a reduction in specific carbon dioxide emissions from its cement plants. This was followed with a commitment to reduce other air emissions from cement plants. CRH has achieved all of these targets a full three years ahead of the planned date, through sustained investment in energy efficient processes and abatement systems, increased use of alternative fuels and raw materials and the technical development of lower carbon intensity products. CRH is now focusing on achieving its new public commitments in these areas by the target date of 2020.
Production facilities are being progressively upgraded to optimise the use of both energy and materials and to reduce emissions.
CRH companies won a total of 266 environmental awards in 2012. In addition CRH is ranked among sector leaders by leading Socially Responsible Investment (SRI) rating agencies.

Sustainability is a critical concern for social, economic and environmental reasons. The lesson focuses on the processes involved in the production of cement. It describes the measures taken by CRH to control energy use and atmospheric emissions such as dust and greenhouse gases.
In the case of a house, the building envelope consists of a floor, foundations, walls and a roof; openings are usually provided in the walls for doors, windows and air vents. In this lesson we will look at the materials used to construct the main elements of the building envelope.
This lesson is an introduction to chemical bonding. Bonding is described in terms of sharing or transfer of electrons so that, usually, each atoms ends up with eight electrons in its outer electron energy level. This is referred to as ‘the octet rule’.
There is widespread concern about the long-term sustainability of industrial activities that affect the environment. This lesson describes how a major global building materials company fulfils its corporate social responsibility as it works to reduce or ameliorate the environmental impact of its operations.
This lesson describes how domestic energy requirements can be greatly reduced by making better use of solar heating, by using high quality insulation and by exploiting the thermal capacity of internal structures.
This lesson outlines how cement is produced and looks at the natural materials used in the process. It also outlines how modern production methods minimise energy loss, reuse by-products and contribute positively to the environment.
This lesson describes the manufacture of Portland cement, the most commonly used type of cement in Ireland and the principal ingredient of concrete and mortar.
Ethical behaviour in business, no less than in everyday life, is often taken for granted but the consequences of unethical activity are so grave, as evidenced by the financial crash, that it is vital to set up compliance programmes that promote and support ethical behaviour at all levels of business.
This lesson deals with the chemistry and production process of lime. It also describes some of the many uses to which lime is put in the building, agricultural, industrial and environmental sectors. An interesting topic is the production of magnesium oxide from seawater.
