After United Kingdom, the Republic of Ireland has officially become the 2nd country in the world to declare a climate and biodiversity emergency. It happened after the Oireachtas (Irish parliament) report on Climate Action was accepted by the government and opposition parties without a vote. An amendment to a parliamentary report declaring a climate emergency and calling on parliament to examine how the Irish government can improve its response to the issue of biodiversity loss was accepted. Britain’s parliament became the first in the world to declare a climate emergency, passing the largely symbolic motion on May 1. The step followed 11 days of street protests in London by the Extinction Rebellion environmental campaign group.
