Brazil issues last-ditch plea for countries to submit climate plans ahead of Cop30

Only 28 countries have submitted carbon-cutting proposals to the UN, with some of the biggest emitters yet to produce plans

Brazil has issued an urgent call for all countries to come forward with strengthened national plans on the climate, in a last-ditch attempt to meet a key September deadline.

Only 28 countries have so far submitted carbon-cutting proposals to the UN, with some of the biggest emitters of greenhouse gases - including China and the EU - still to produce their plans.
