Barcelona City council has an impressive programme of staff engagement and training to drive behaviour change and reduction in energy consumption. The Ajuntament més Sostenible (A+S) Programme has been developed by Barcelona City Council and includes specific training for professionals working with the City Council to achieve a cultural change in favour of sustainability. The A+S Programme includes training across a range of environmental areas related to the greening of municipal building services. One of the priority areas of action is the greening-up of its own operations, the initiatives for improvement are detailed in the “+ Sustainable City Council” programme which is part of Barcelona’s Agenda 21 and another example of the city council’s commitment to local and global sustainability. Another main area of focus is sustainable and responsible procurement to which ensures the inclusion of environmental and social criteria in certain products and services. The programme is widely communicated both internally and externally via an e-bulletin, the website, training and specific campaigns.
