Many countries have stated in their INDCs that they intend to use some form of international emissions trading scheme to implement their contributions. In order to ensure the environmental integrity of these transactions, the agreement requires the parties to respect accounting practices and to avoid double counting of “mitigation results transferred internationally.” In addition, the agreement will create a new mechanism that would help contain and support sustainable development and could produce or certify negotiable emission units according to its design. It will also enable the contracting parties to gradually strengthen their contributions to the fight against climate change in order to achieve the long-term objectives of the agreement. How each country is on track to meet its obligations under the Paris Agreement can be constantly monitored online (via the Climate Action Tracker  and the climate clock). Fortunately, more than 4,000 U.S. heads of state and government have stood up in cities, states, tribes, businesses, colleges and universities to say they will 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. With the support of WWF and more than two dozen other organizations, We Are Still In has been welcomed by other countries and praised by Americans who want to show the world that U.S.
leaders far exceed the federal government`s executive on climate change. While mitigation and adjustment require more climate funding, adjustment has generally received less support and has mobilized fewer private sector actions.  A 2014 OECD report showed that in 2014, only 16% of the world`s financial resources were devoted to adaptation to climate change.  The Paris Agreement called for a balance between climate finance between adaptation and mitigation, highlighting in particular the need to strengthen support for adaptation from the parties most affected by climate change, including least developed countries and small island developing states. The agreement also reminds the parties of the importance of public subsidies, as adjustment measures receive less public sector investment.  John Kerry, as Secretary of State, announced that the United States would double its grant-based adjustment funding by 2020.  On June 1, 2017, President Trump announced his intention to withdraw the United States from the agreement. In response, other governments have strongly reaffirmed their commitment to the Agreement.
