But without the United States, the balance between the parties that signed the Paris agreement shifts in China`s favor on key issues that have not yet been resolved. According to Michael Oppenheimer, a climatologist at Princeton University in New Jersey, China could resist demands for follow-up and detailed reports on how countries implement their policies and achieve their goals. « It doesn`t bode well for the effectiveness of the Paris agreement, » he says. In the last three years, there has been no mass exodus from the pioneering agreement. But some countries, including U.S. allies like Japan, have eased emissions cuts. The United States itself has not met the objectives it had promised to achieve to avoid the most pessimistic scenarios of extreme weather. Democratic candidate Joe Biden said that if elected president, he would reinstate the Paris accord early in his presidency. The United States could become a party to the Paris Agreement 30 days after the official information of the United Nations Framework Convention on Climate Change. The country is then expected to present a new commitment to reduce emissions by 2030. All countries need to strengthen, accept that global emissions must reach zero by 2050 and take great strides to achieve this, says Niklas Huhne of the NewClimate Institute for Climate Institute for Climate Institute for Climate Policy and Global Sustainability in Germany.
The task becomes more difficult. Although high-emigration countries are increasingly interested in containing warming, experts warn that current climate and energy policies are not enough to keep the world below 2 degrees Celsius of warming. This year, greenhouse gas emissions have fallen significantly – due to lower travel activity and economic activity during the coronavirus pandemic – but this will do little to bring the world closer to its climate goal, experts warn. « The ue-Green agreement and the commitments of China, Japan and South Korea on CO2 emissions neutrality indicate the inevitability of our collective transition from fossil fuels, » said Laurence Tubiana, one of the architects of the Paris Agreement and now executive director of the European Climate Foundation. The NDC partnership was launched at COP22 in Marrakech to improve cooperation so that countries have access to the technical knowledge and financial support they need to achieve major climate and sustainable development goals. The NDC partnership is led by a steering committee made up of industrialized and developing countries and international institutions and is supported by a support unit organized by the World Resources Institute and based in Washington, D.C. and Bonn, Germany.
