To achieve this, the city’s energy policy focuses on the diversification of primary energy sources and increasing the energy efficiency of the economy. The city’s Sustainable Energy Action Plan (SEAP) consists of a set of technical measures to be applied in 2015-2025. A key objective of the plan is to change citizens’ habits and behaviour, to improve energy efficiency and reduce waste through measures focusing on residential and service buildings, the transport sector and public lighting.

It is the goal of the municipal administration for Maia to become an example to other cities with regards to energy efficiency by creating rankings among public entities, managing and disseminating best practices, and developing an evolutionary barometer model for targeted improvements each year.


  • Carbon neutral by 2050, going beyond the SEAP 2050 target (2 tons of CO2 equivalent per inhabitant);
  • 35% of energy from RES by 2030 and 100% by 2050;
  • Reducing GHG emissions from 5.89 t CO2 equivalent per inhabitant in 2009 to 4.13 in 2025;
  • 35% increase energy efficiency by 2030 and 45% by 2050;
  • Net Zero Carbon City.
