If countries stick to the promises they’ve made, the Paris Agreement will become international law by the end of this year. Climate Home reports that 57 countries have now indicated that they will ratify the Paris Agreement in 2016. What’s more, these countries represent 57.88% of global emissions, which means the accord would hit the 55 countries representing at least 55% of the world’s emissions threshold needed to bring the agreement into effect.

“Under this scenario, the Paris Agreement will enter into force by the end of the year,” said the Berlin-based consultancy Climate Analytics, which provided the data.

Announcements made by Japan and New Zealand on Wednesday tipped the scales on both of the requirements needed to bring the accord into force. UN Framework Convention on Climate Change Executive Secretary Patricia Espinosa said Wednesday that she was “very hopeful” that enough countries would make good on their promises to bring the agreement into force this year.
