Rich nations yet to deliver on 2022 Pakistan flood aid promise — UN

A year after deadly floods inundated a third of Pakistan, the broken promises to rebuild the country present "a litmus test for climate justice," the head of the United Nations has said.

"Billions were pledged" by rich nations in the aftermath of the disaster, said Secretary-General Antonio Guterres on Wednesday, "but the vast majority was in loans. And Pakistan is still waiting for much of the funding."

"Delays are undermining people's efforts to rebuild their lives," the UN chief said during a special session dedicated to the catastrophe, adding that the Asian nation was "a double victim - of climate chaos and of our outdated and unjust global financial system."

Some $9 billion was pledged to help reconstruct Pakistan in January, though it is still reeling from the effects of the heavy monsoon rains, which displaced eight million people and killed some 1,700.

More than eight million residents in areas hit by the floods lack access to clean water, Guterres said, while noting that Pakistan is responsible for less than one percent of the greenhouse gas emissions that likely fueled last year's "climate chaos."

"The countries that contributed most to global heating must contribute most to righting the harm it has done."
