Map from Climate Analytics
It was all a grand theater. Greens brag that the Paris agreement was signed by “179 countries”, but it means nothing until they get 55 nations controlling 55% of the worlds (man-made) emissions. Right now, they’ve had a resounding response from no country that matters. (Forgive me Norway, with 0.14% of man-made emissions, right now, you are in a small group which includes Palestine, Palau, and North Korea.)
What they need:
In accordance with Article 21, paragraph 1, of the Paris Agreement, the Agreement shall enter into force on the thirtieth day after the date on which at least 55 Parties to the Convention accounting in total for at least an estimated 55 % of the total global greenhouse gas emissions have deposited their instruments of ratification, acceptance, approval or accession with the Depositary.
What they’ve got: 22 states which produce 1% of man-made emissions.
Paris Agreement – Status of Ratification
As of 2 August 2016, there are 179 signatories to the Paris Agreement. Of these, 22 States have also deposited their instruments of ratification, acceptance or approval accounting in total for 1.08 % of the total global greenhouse gas emissions.
So only 33 countries and 54% of global emissions to go. (And they obviously mean “human emissions”, not “global emissions” or they’ll have to get Nero, Davy Jones, and the Union of Phytoplankton to sign up. )
So the UN has promises that cover 1% of the 3 to 4% of global emissions that mankind makes — a grand total 0.04% of total global emissions being as generous as possible.
The ratified list: Barbados, Belize, Cameroon, North Korea, Fiji, Grenada, Guyana, Maldives, Mauritius, Nauru, Norway, Palau, Palestine, Peru, St Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Samoa, Seychelles, Somalia and Tuvalu.
Note that Climate Analytics points out that the number was not set higher at 60% because then a block could have formed to stop it. The biggest emitters are: China, 20%; USA, 18%; EU, 12%; Russia, 7%; India, 4%; Japan, 4%. Think of it the other way, it’s a challenge to organize a block of 45% refuseniks — whatever China and the US do will make or break this. Presumably all the little countries can be bought off with UN pork or threats, and the world is waiting til the US election.
For anyone who wants to know the fine print of the agreement:
On 17 March 2016, the Secretary-General of the United Nations, acting in his capacity as Depositary of the Paris Agreement, transmitted 
certified true copies of the Agreement to all Member States of the United Nations and Parties to the Convention.
UPDATE: Thanks to questions from commenters I found out which countries are in that club and added the map. :- )
