Kyoto Protocol adopted. This is the world`s first agreement on reducing greenhouse gas emissions, which will come into force in 2005. Indeed, research shows that the cost of climate activity far outweighs the cost of reducing carbon pollution. A recent study suggests that if the United States does not meet its climate targets in Paris, it could cost the economy up to $6 trillion in the coming decades. A lack of compliance with the NPNs currently foreseen in the agreement could reduce global GDP by more than 25% by the end of the century. Meanwhile, another study estimates that achieving – or even exceeding – the Paris targets by investing in infrastructure in clean energy and energy efficiency could have great benefits globally – about $19 trillion. From 30 November to 11 December 2015, France hosted representatives from 196 countries at the end of the Un Climate Change Conference (UN), one of the largest and most ambitious global meetings ever held. The goal was nothing less than a binding and universal agreement to limit greenhouse gas emissions to levels that would prevent global temperatures from rising more than 2oC above the lower temperature levels set before the start of the industrial revolution. 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). The EU and its member states are individually responsible for ratifying the Paris Agreement. There was a strong preference for the EU and its 28 Member States to simultaneously table their ratification instruments to ensure that neither the EU nor its Member States commit to commitments that belong exclusively to the other and there was concern that there was a disagreement on each Member State`s share of the EU-wide reduction target.
just as Britain`s vote to leave the EU could delay the Paris pact.  However, on 4 October 2016, the European Parliament approved the ratification of the Paris Agreement and the EU tabled its ratification instruments on 5 October 2016 with several EU Member States.  InDCs become CNN – 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. We have one of the most frequent energy reserves in the world, enough to lift America`s poorest working people out of poverty. But as part of this agreement, we are effectively locking up these reserves and taking the great wealth of our nation – it is a great wealth, it is a phenomenal wealth. Not so long ago, we had no idea that we had such wealth and that we were leaving millions and millions of families trapped in poverty and unemployment.
