On a route that began at Praça Martim Moniz and went up Avenida Almirante Reis to Alameda, hundreds of demonstrators sang protest chants and held up dozens of posters and banners. Among these, some warned that "There is no planet B!" and for the "Planetary precariousness", demanding governments for "Renewable energies for all".

Among the protesters was Ana Pereira, a 30-year-old financial analyst who had a poster slung over her shoulders and a dinosaur puppet in her left hand to remember the planet's own extinction scenario if nothing is done to contain climate change.

“Climate change does not have enough airtime in the media and it is important to draw attention to it”.

Equipped with an electric bicycle that brought her from Olivais to Lisbon's 'Baixa', 53-year-old Elsa Mota stressed that she had come to participate in the initiative not only out of concern for her generation, but especially for the younger ones, who they surprised her by not being outnumbered on this afternoon's march.

“You don't see many kids at the demonstration. I was waiting for more kids”, admitted the teacher, acknowledging that there is still “a deficit of collective conscience in terms of environmental protection, but noting that action is needed: “I couldn't just sit there, I have three children”.

Convened by the Save the Climate platform, the demonstration brought together several Portuguese organizations calling for drastic cuts in greenhouse gas emissions, a fair transition and global climate justice, on a global-scale initiative to create pressure on COP26.

More than 120 political leaders and thousands of experts, activists and public decision-makers are gathered until 12 November in Glasgow, Scotland, to update countries' contributions to reducing greenhouse gas emissions by 2030.
