Nations Agree Global Climate Pact Rules, But Seen As Weak
Negotiators in Poland have finally secured agreement on a range of measures that will make the Paris climate pact operational in 2020.
Last-minute rows over carbon markets threatened to derail the meeting and delayed it by a day.
Delegates believe the new rules will ensure that countries keep their promises to cut carbon.
The Katowice agreement aims to deliver the Paris goals of limiting global temperature rises to well below 2c.
The common rulebook envisages flexibility for poorer nations.
Developing countries seek recognition and compensation for the impact of rising temperatures.
The idea of being legally liable for causing climate change has long been rejected by richer nations, who fear huge bills well into the future.
