On December 12, 2015, in Paris, 195 countries signed a global agreement that sets out an action plan that the signatories believe has the potential to curtail future climate change by limiting the increase in global warning to below 2℃ above pre-industrial levels. The agreement does not impose limits but it rather relies on each nation's voluntary plan to curtail GHG emissions. The agreement will enter into force after 55 countries that account for at least 55% of global GHG emissions have ratified the agreement.
