The overall objective of SOLAR is to develop tools for measuring the carbon footprint of the airports in Puglia, Albania and Montenegro and activate policies for carbon emission reduction in the programme area. To achieve this goal the project will facilitate knowledge pooling and sharing of best practices among partners, building a joint model to reduce carbon footprint in the air transport sector at cross-border level. Partners will carry out several actions to become cleaner and more efficient: better energy efficiency and low carbon energy planning; working with airlines to reduce runway taxiing times; encouraging external operators, service companies, ground handlers, catering companies, employees, passengers and visitors to use public transport or more sustainable transport modalities, environmentally friendly waste policies, as well as to reduce plastic use.
