The adoption of the agreement sends a message to the world that countries are taking the fight against climate change seriously. It is a remarkable triumph that the 196 parties to the Convention have reached this agreement. The agreement recognizes the role of non-partisan stakeholders in the fight against climate change, including cities, other sub-national authorities, civil society, the private sector and others. Article 21, paragraph 1, of the Paris Agreement enters into force thirty days after at least 55 countries representing 55% of global greenhouse gas emissions filed their instruments for ratification, acceptance or approval with the Secretary-General of the United Nations. A timetable including greenhouse gas emissions to determine the threshold can be set on unfccc.int/files/paris_agreement/application/pdf/10e.pdf A growing chorus of U.S. business leaders, national and municipal officials, civil society groups and foreign partners condemned the president`s announcement that „the United States will stop ending the implementation of the non-binding Paris Agreement effective Thursday, June 1.“ As Susan Rice, a former national security adviser, put it, taking the United States out of the Paris Agreement is a „coup for America`s global leadership for the foreseeable future.“ In foreignpolicy.com, a group of former Obama administration officials presents a strong and compelling exhibition of „Why Paris is Abandoned is a Disaster for America.“ They explain why meeting our Paris commitments would be much better not only for climate outcomes, but also for our national security, for the future of our economy and for the image of the United States in an increasingly unstable world. An important point, which is taken into account by many observers, is that, under the Paris Agreement, the President is able to reduce our national contribution (NDC) to reducing greenhouse gas emissions, when that would be myopic at best, since states are not legally obliged to meet certain emissions targets. If the objectives themselves are essentially voluntary, the president`s idea that the United States must withdraw completely from the agreement to relieve us of its supposed economic costs is wrong.
