The aim of this project is to reduce carbon dioxide emissions from construction sites.

The aim of this project is to reduce carbon dioxide emissions from construction sites, as well as to incentivise the construction industry to adopt sustainability strategies. The Sustainability and Architecture Association (ASA) is the entity that will develop the initiative.

To this end, energy efficiency is sought in the design and construction phases of a building, reducing the environmental and economic costs of the works through the rational use of resources and energy savings. The initiative will facilitate self-assessment and continuous improvement to reduce CO2 emissions in buildings.

An intrinsic difficulty for the development of the project is the difficulty of raising awareness in the construction market of the environmental impacts that this activity entails.

The expected objectives are:

• To achieve a revised and updated methodology and protocol that is common for the calculation of the Carbon Footprint generated in phase I of the project.
• An updated tool (‘arCo2’) that becomes a quantitative and measurable reference.
• A results report analysing the data obtained with the tool. Thanks to ‘arCo2’, it will be possible to access the information provided by different technicians and draw conclusions by comparing the results.
• Develop a revised and updated database with an inventory of the life cycle of construction products. To this end, it has the collaboration of the Eduardo Torroja Institute of Construction Sciences (CSIC).
• Representation in the Carbon in Construction Working Group, chaired by the Spanish Office for Climate Change and created during the first phase of the project.
• Disseminate the contents and train construction technicians.
