The agreement not only reduced emissions, but also introduced the Clean Development Mechanism to act on carbon. This meant that countries that did not meet the reduction targets could «buy» the right to additional emissions from households in less polluting countries. They could also be offset by measures to combat climate change in developing countries. Specific results of increased attention to adjustment financing in Paris include the announcement by the G7 countries of $420 million for climate risk insurance and the launch of a Climate Risk and Early Warning Systems (CREWS) initiative.  In 2016, the Obama administration awarded a $500 million grant to the «Green Climate Fund» as «the first part of a $3 billion commitment made at the Paris climate talks.»    To date, the Green Climate Fund has received more than $10 billion in commitments. The commitments come mainly from developed countries such as France, the United States and Japan, but also from developing countries such as Mexico, Indonesia and Vietnam.  The Paris Agreement is the world`s first comprehensive climate agreement.  The net supply of carbon units on the carbon market depends on the ability of Appendix I countries to reduce their emissions beyond their QELROS – freeing up units that can then be traded on the market – and on the ability of project proponents and non-annex countries I to produce carbon units within the CDM , which can then be traded on the carbon market. Overall supply within the CDM is still limited by rules that prevent the production of carbon units from certain types of projects and greenhouse gases. The reason for these restrictions is the need to ensure that the CDM produces real, measurable and long-term reductions, in addition to those that would have occurred without the project and that promote sustainable development.  The supply of carbon units has been active in the market for many years, more than 8,500 CDM projects are in the pipeline, of which more than 7,500 have been registered.  However, in 1992, the UNFCCC drew a distinction between The Annex I contracting parties with respect to some of the key climate change commitments, such as the requirement to adopt policies and measures under Article 4.2 (a). More importantly, the obligations of the agreement were primarily based on the inclusion of countries in Schedule I (a list of countries that at the time included the OECD and other countries in transition to a market economy) or Schedule II (a subset of Schedule I, including oecd countries at the time).
