"Our contribution to greenhouse gas emissions is less than 1%. The G20 is responsible for 80% of the emissions. The pursuit of profit over the well-being of humanity is not right. It is unjust."

[David Kabua, President, Republic of Marshall Islands]

"Everyone here says they are committed to 1.5, but the actions we take will speak louder. Yesterday, 19 fellow high-ambition coalition leaders and I came together to demand faster, stronger action to respond to the climate crisis. We call for a fossil fuel phaseout and demand that abatement technology not be used to green-light continued expansion."

[Surangel Whipps Jr, President, Palau]

"We urge all countries, especially major emitters, to present their updated and more ambitious nationally determined contributions, as well as updated net zero targets and energy transition plans with commitments to no new coal, oil, and gas."

The world's top two polluters, China and the U.S., were not invited to speak
