Climate Change

Climate change is one of the greatest global challenges and, at Buzzi Unicem, we recognize the efforts made by the scientific community to mitigate it. This is why we operate in line with the objectives set by international climate protocols, and we are committed to reducing our CO2 emissions in all the countries in which we operate.

Our Target

Although there are many factors in play, and not all of these are easy to predict and under the control of Buzzi Unicem, by 2022 we plan to achieve a reduction of CO2 emissions, based on 2017 production capacity, of 5% compared to 2017 levels.

Many industrial sectors, including ours, are called to take action and dialogue together to achieve the 2050 goal of climate neutrality. Buzzi Unicem, in line with the stated aim of the European Association of cement producers (Cembureau), has embraced one of the greatest challenges of the century, thanks to the technical know-how that distinguishes its projects.

Scope 1 emissions are direct emissions from sources owned or controlled by the company. In the cement production process, most of the CO2 is generated during the production of clinker, the basic constituent of cement. The main sources are combustion and decarbonation of raw materials.

Scope 2 emissions are those associated with the electricity consumed, in our case, for the production of cement. They are defined as "indirect" because they do not take place in the cement plant.

Scope 3 emissions are generated from sources not owned or controlled by the company but they are a consequence of its activities and, therefore, they are defined “indirect” emissions. For cement production, Scope 3 includes, for example, CO2 emissions from transport activities and extraction and production of purchased materials and fuels.

The production of cement and clinker is a process that requires a high amount of both electrical and thermal energy:

  • The production of cement, and in particular of clinker, requires the use of thermal energy, supplied by fuels. In fact, to produce clinker with good properties it is necessary to reach a temperature of about 1 450 °C.
  • Electricity consumption is due to the preparation of raw materials, the clinker burning process and the cement grinding. It corresponds to about 12% of the total energy consumed.
