The meeting point is scheduled for 3 pm on Sunday, next to the Relógio roundabout, close to one of the access points to the airport, and the objective is to promote "disruption of peak flight times at Lisbon Airport, the most polluting infrastructure in the country at the moment”.

For environmentalists, the airport is “a mirror not only of the touristification facing cities, but also of the monstrous size of the global aviation industry.”

Quoted in the statement, the spokesperson, Maria Lourenço, says that the “great social transformation” that is necessary “can only be led by popular power and not by companies and governments”.

"To avoid climate and social collapse, we need to cut at least 85% of greenhouse gas emissions in Portugal by 2030," he said, contesting the possibility of any expansion project and calling for an end to the "absurdity of private jets and short-haul flights (such as Lisbon-Porto)".

By 2030, it will be necessary to reduce the impact of commercial aviation and, in parallel, “a massive investment in a free and electrified public transport network that serves the entire territory and has good international connections” is needed, he added.

According to the movement, "Lisbon airport and the aviation industry are one of the main culprits in Portugal for the climate crisis", criticizing the decision to build a new structure.

In Portugal, “there is a parliamentary consensus on the construction of a new airport and the expansion of this deadly industry for everyone. This cannot happen: each new emitting infrastructure is a carbon bomb that will fall on us”, say the activists, who lament the result of the legislative elections.

“With the election results, it has become even clearer that this system will not save us. In fact, quite the opposite: it is collapsing and pushing us into the climate abyss,” they accuse.

Therefore, “it is up to us, the common people, to pull the emergency brake, build popular democracy and enter into climate resistance now”, they argue.
