In order to achieve the emission reduction objectives, the Agreement establishes a "bottom up system' where Parties will have to prepare and communicate successive nationally determined contributions (NDC) every five years with the aim of progressively improving their efforts. In addition to their NDC, Parties should also formulate long-term, mid-century low GHG development strategies, and submit them by 2020 that demonstrate how their efforts will contribute to the goal of zero-net emissions by the second half of this century. Albania has signed the Paris Agreement on the 22nd of April 2016 in New York, and the agreement will enter into force after 55 countries that account for at least 55% of global emissions have deposited their instruments of ratification.
