The EU`s national contribution to the Paris Agreement is to reduce greenhouse gas emissions by at least 40% by 2030 compared to 1990, as part of its broader climate and energy framework by 2030. All the main EU legislation to achieve this goal has been adopted by the end of 2018. People`s Climate March in New York. More than 400,000 people – including a large WWF delegation – are showing that governments must act urgently to combat climate change, two days before world leaders gather in the city for a UN-led summit on the issue. The Global Climate Action Summit takes place. Leaders of states and regions, cities, businesses, investors and civil society are calling on national governments to join forces to strengthen the fight against climate change by 2020, when global greenhouse gases will have to fall sharply to avoid the worst consequences of climate change. Because climate change is fuelling rising temperatures and extreme weather events, it is endangering our air, water and food; Widespread diseases and endangers our homes and security. We are facing a growing public health crisis. The president`s promise to renegotiate the international climate agreement has always been a smokescreen, the oil industry has a red phone at the Home Office, and will Trump bring food trucks to Old Faithful? According to the United Nations Environment Programme (UNEP), temperatures are expected to rise by 3.2oC by the end of the 21st century, based solely on the current climate commitments of the Paris Agreement. To limit the increase in global temperature to 1.5 degrees Celsius, annual emissions must be below 25 Gigaton (Gt) by 2030.
With the current commitments of November 2019, emissions by 2030 will be 56 Gt CO2e, twice the environmental target. To limit the increase in global temperature to 1.5 degrees Celsius, an annual reduction in emissions of 7.6% is needed between 2020 and 2030. The four main emitters (China, the United States, the EU-27 and India) have contributed more than 55% of total emissions over the past decade, excluding emissions due to land use changes such as deforestation. China`s emissions increased by 1.6% in 2018 to a peak of 13.7 Gt CO2 equivalent. U.S. emissions account for 13% of global emissions and emissions have increased by 2.5% in 2018. EU emissions, which account for 8.5% of global emissions, have fallen by 1% per year over the past decade. Emissions fell by 1.3% in 2018. In 2018, 7% of India`s global emissions increased by 5.5%, but its per capita emissions are one of the lowest in the G20.  Fortunately, more than 4,000 U.S. heads of state and government stood up in cities, states, tribes, businesses, colleges and universities to say they would continue to support climate change measures to meet the commitments made by the Paris Agreement as part of the We Are Still In movement.
These leaders have crossed cultural, political, economic and social divides to meet the challenge of the climate crisis. These leaders in the United States could achieve a 37% reduction in emissions below 2005 levels by 2030, with a significant increase in measures by 2030 and a 49% reduction in emissions from 2005 levels, with federal reintegration beginning aggressively from 2021.
