The global wave of
school strikes for the climate over the past year has "achieved nothing" because greenhouse gas emissions have continued to rise, Greta Thunberg has told activists at UN climate talks in Madrid.
Thousands of young people were expected to gather at the UN climate conference and in the streets of the Spanish capital on Friday to protest against the lack of progress in tackling the climate emergency, as officials from more than 190 countries wrangled over the niceties of wording in documents related to the Paris accord.
In the four years since the landmark agreement was signed, greenhouse gas emissions have risen by 4% and the talks this year are not expected to produce new commitments on carbon from the world's biggest emitters.
Thunberg, whose solo protest in Sweden in 2017 has since snowballed into a global movement, said that although schoolchildren had been striking around the world, this "has not translated into action" from governments.
Thunberg expressed hope for the UN negotiations but doubted whether governments had got the message, and warned the world could not afford continued inaction.
She hopes COP25 will reach something concrete and increase awareness among people, and that world leaders and people in power grasp the urgency of the climate crisis.
Although young people would keep striking, Thunberg said, they wanted to stop – if governments made credible promises and showed a willingness to act.
As well as the march and a sit-down protest in the conference centre, there were shows of international solidarity among young people from around the world, including a picnic in a central Madrid park. The conference centre was flooded with hundreds of schoolchildren accompanied by their parents, where negotiators were working on a draft text to clarify aspects of the Paris agreement.
Young people voiced their frustration at protests inside and outside the conference centre on the outskirts of Madrid.
Many of the young people joining the conference from developing nations around the world bore personal witness to suffering they had experienced or seen.
