The Paris Agreement expected the world to set a higher annual target by 2025 to build on the $100 billion target for 2020 and put in place mechanisms to achieve that scale. In 2001, the previous meeting (COP6 bis) continued in Bonn, at which the necessary decisions were taken. After some concessions, supporters of the protocol (led by the European Union) managed to secure the agreement between Japan and Russia by allowing more levels of carbon dioxide. Among other things, countries need to report on their greenhouse gas inventories and progress against their targets, so that external experts can assess their success. Countries should also review their commitments by 2020 and present new targets every five years to further reduce emissions. .
