InDCs become CNDs – nationally determined contributions – as soon as a country formally adheres to the agreement. There are no specific requirements as to how or how many countries should reduce emissions, but there were political expectations about the nature and rigour of the targets set by different countries. As a result, the scale and ambition of national plans vary widely, largely reflecting each country`s capacity, level of development and contribution to emissions over time. China, for example, has committed to cleaning up its CO2 emissions by 2030 at the latest and reducing CO2 emissions per unit of gross domestic product (GDP) by 60-65% by 2030 from 2005 levels. India has set a target of reducing emissions intensity by 33-35% from 2005 levels by 2030 and producing 40% of its electricity from non-fossil fuels. While the agreement has been welcomed by many, including French President Francois Hollande and UN Secretary-General Ban Ki-moon, criticism has also emerged. James Hansen, a former NASA scientist and climate change expert, expressed anger that most of the agreement is made up of « promises » or goals, not firm commitments.  He called the Paris talks a fraud with « nothing, only promises » and believed that only a generalized tax on CO2 emissions, which is not part of the Paris agreement, would force CO2 emissions down fast enough to avoid the worst effects of global warming.  Seven other states have signed the Paris Agreement but have not ratified it. While the Paris Agreement ultimately aims to limit global temperature increase to 1.5 degrees Celsius this century, many studies evaluating the voluntary commitments of some countries in Paris show that the cumulative effect of these emission reductions will not be significant enough to keep temperatures below that ceiling.
Indeed, the targets set by the target countries should limit the future increase in temperature between 2.7 and 3.7 degrees Celsius. At the same time, recent assessments of countries` developments in the framework of their climate targets in Paris indicate that some countries are already not meeting their commitments. At the 2011 UN Climate Change Conference, the Durban Platform (and the ad hoc working group on the Durban Platform for Enhanced Action) were created to negotiate a legal instrument to mitigate climate change from 2020. The resulting agreement is expected to be adopted in 2015.  On the other side of the debate are the head of the Environmental Protection Agency, Scott Pruitt, a virulent anti-climate extremist, and chief strategist Steve Bannon, widely known for shaping the president`s nationalist views and fueling his distrust of international agreements. Only two countries have refused to participate in the Paris Agreement, the landmark climate agreement on reducing greenhouse gas emissions signed by almost all nations. One of them, Syria, is in ruins after six years of civil war. The other, Nicaragua, boycotted the agreement in protest at its initial unambitious targets and its inability to blame countries for their emissions targets. The 32-part document sets out a framework for global action on climate change, including climate change mitigation and adaptation, support for developing countries and transparency of reporting, and strengthening climate change goals. Here`s what to do: these rules of transparency and accountability are similar to those in other international agreements. Although the system does not include financial sanctions, the requirements are intended to easily monitor the progress of individual nations and promote a sense of overall group pressure, discouraging any towing of feet among countries that might consider it.
