The Secretary-General of the United Nations, António Guterres, has urged young people to continue their fight for climate justice in the wake of unprecedented crowds worldwide at the 20 September climate strike.
Speaking at the first-ever UN Youth Climate Summit, held the day after millions of people joined the historic climate strike, Guterres said:
I encourage you to go on …
To keep your mobilisation, and more and more to hold my generation accountable.
My generation has largely failed until now to preserve both justice in the world and to preserve the planet. My generation has a huge responsibility.
It is your generation that must make us be accountable to make sure that we don’t betray the future of humankind.”
Meanwhile, the Climate Action Summit in New York on 23 September will kick off a series of high-level events at UN headquarters to drive action for people and the planet, running alongside the UN General Assembly’s annual general debate.
World leaders will discuss progress on the Sustainable Development Goals (SDGs), universal healthcare for all, and securing a broad-based development partnership for small island developing States.
