Officials from around the world have agreed upon a set of rules to govern the 2015 Paris climate accord after two weeks of UN talks in Poland.
Michal Kurtyka, a Polish official chairing the talks in Katowice, sealed the deal on Saturday after diplomats and ministers from almost 200 countries approved.
The UN talks were meant to provide firm guidelines for countries on how to transparently report their greenhouse gas emissions and their efforts to reduce them.
Scientists say emissions of gases such as carbon dioxide need to drop sharply by 2030 to prevent potentially catastrophic global warming.
The meeting postponed decisions on pledging more ambitious action to fight global warming and on regulating the market for international carbon emissions trading.
