Porto is the epicenter of a region with more than 1.7 million inhabitants – the Metropolitan Area of Porto.

It is the 4th most populous municipality and the 3rd most densely populated in the country.

In the last few decades, the city is getting more attractive for living, studying, and hosting businesses.

One in every five startups nationwide are in Porto and the city’s connection to academia and research centres contributed to the creation of a hub known for generating, attracting, and retaining knowledge.

Porto is an ecosystem of innovation and environmental sustainability in areas as climate action, circular economy, and protection of natural heritage.

Climate change

The stability of the global climate system is at risk as a result of the high concentration of Greenhouse Gases (GHG) in the global atmosphere. Mitigating these emissions is urgently needed to avoid unpredictable consequences on the natural, economic, and social systems. The European Union has been leading the way: member states should set a target of 55% reduction in 2030 and neutrality in 2050. At a national level, the Climate Framework Law of 2021 sets a reduction in emissions of at least 55% by 2030, 65% by 2040, and 90% by 2050. Reducing GHG emissions requires ambitious measures and high public and private investment, but at the same time represents an opportunity for competitiveness, employment, and social justice.

The path towards carbon neutrality in Porto is demanding and calls for collective action for collective benefits. Porto’s neutrality can only be achieved with concrete actions carried out by all stakeholders, regardless of their size, previous action or legal personality.
The Municipality of Porto believes that a common vision and goal for decarbonization can help all stakeholders move in the same direction to fulfill a common purpose.
Therefore, with the Porto Climate Pact we intend to awaken citizens and organizations to action and to create a large community of learning, sharing ,and mutual support. Signing the Pact is voluntary, non-binding and free of charge.
The ambition is that Porto becomes the national leader in climate action, anticipating carbon neutrality.
Porto was selected by the European Commission to be part of the group of 100 Climate neutral and Smart Cities, and as a Mission City, Porto has the ambition to be a leader, at national and European level, in climate action, anticipating carbon neutrality to 2030.


Municipal ambition to reduce carbon emissions by 2030 (compared to 2004).


Reduction of carbon emissions achieved in 2020 in Porto (compared to 2004).


The Promoter of the Porto Climate Pact is the Municipality of Porto.
The Municipality of Porto has been monitoring Greenhouse Gas (GHG) emissions since 2008, through the Porto Energy Agency, and has advocated a 60% GHG reduction by 2030.
The role of the Municipality of Porto in the decarbonization of the city has been systematic, but limited, as municipal assets are only responsible for 6% of total GHG emissions. Most GHG emissions in the city come from the buildings, residential and services sectors (~50%) and transports (~40%). Hence the importance of the collective action that the Porto Climate Pact seeks to accelerate the energy transition and achieve an emissions neutral balance by 2030.

DECO has implemented a set of measures to reduce energy and water consumption in its regional structures and headquarters. It has promoted the acquisition of certified sustainable materials and products and encouraged its employees to reduce waste. Concerning mobility, it provides employees with a free monthly public transport pass, also encouraging them to hold meetings at a distance.

Portugal is one of the European countries most vulnerable to the impacts of climate change. Local authorities, which are closest to consumers, are the ones who know their reality best and can implement measures to protect citizens and ecosystems more effectively. DECO, as the voice of consumers, subscribed to this Pact because it considered that this great plan of anticipating carbon neutrality should call for everyone.

For Metro do Porto, contributing to decarbonization is a big goal. The new lines under construction will, moreover, allow 17000 cars to be taken off the streets every day and, as a result, reduce CO2 (carbon dioxide) emissions by 4000 tons per year. Projects such as these were, moreover, subject to an Environmental Impact Study that attests well to the company's care with this matter.

Metro do Porto is proud to adhere to the Porto Climate Pact. Respect for the environment, through sustainable mobility, is one of our central concerns. Public Transportation is the backbone of a city's decarbonization. In addition to the environmental dimension, at the level of positive environmental externalities, by the net effect on the CO2 emission balance for the atmosphere, a rail operation in the urban context, scaling up collective mobility solutions.
