Green Flag

Citizenship, prosperity and well-being in society are achieved through respect for others, for future generations and for the planet on which we live.

The Green Flag identifies and recognizes the good sustainability practices of territories in Portugal, as a materialization of this respect. It challenges government bodies and the general public to plan for a better future. Coordinated by ABAAE FEE Portugal in partnership with MEO, the Green Flag symbolizes a commitment to sustainability. It is an aggregating concept that distinguishes municipalities (ECOXXI) and parishes (Eco-Freguesias XXI), which want to be an integral part of this movement for change and therefore comply with a set of sustainability criteria.

The Agenda 21 indicators are essential to citizen life and to municipal life as the core of modern democracy. All the more so in times of crisis, which require greater efforts to reinforce the values of sustainability and thus improve the lives and dignity of citizens. (2014)

We applied for ECOXXI in order to continue the work we have done and because we see this program as an important working tool as an indicator of the municipality's sustainability. (2020)

In addition to ECOXXI being a tool for ʺinternal measurementʺ of the municipality's behaviour on environmental issues and sustainable development, the green flag is also a recognition that we don't want to lose but rather raise. (2020)

We applied for ECOXXI because we believe it is an asset for the municipality to evaluate and improve its performance and identify areas for intervention. It allows for an exchange of ideas and has a motivating effect on action. (2020)

The ECOXXI Program is an excellent decision-making tool. In this decade where decarbonization and carbon neutrality of territories will be the main key issues, the ECOXXI Programme, more than ever, should be an instrument for municipalities to adopt. (2020)
