BY THE NUMBERS:
Paris Climate Summit
The number of governments convening in Paris today to discuss a possible new global agreement on climate change.
The temperature increase deemed to be acceptable by the world’s governments.
The projected temperature increase based on current emission levels of greenhouse gases. It is generally accepted that a 5C rise in temperature would be catastrophic.
The number of years global negotiations on climate change have been going.
The emissions cuts that were to be made by 2012, compared with 1990 levels, agreed in 1997 under the Kyoto Protocol. It was never ratified by the US Congress, and with the world’s largest emitter outside of the Protocol, it faltered. None of the countries in the Protocol that blew their emissions targets have ever been sanctioned.
The number of countries in agreement on emissions reductions at the Copenhagen Climate Summit of 2009. Unfortunately it didn’t translate into a legally binding treaty.
The emissions cut pledge from the EU for Paris, compared with 1990 levels.
The emissions cut pledge from the US, compared with 2005 levels.
The year China has said its emissions will peak.
The countries of the world responsible for two thirds of emissions have come up with their targets (known as Intended Nationally Determined Contributions). Together, these emissions cuts, if achieved, will mean a global temperature increase of 2.7C.
According to the recently published state of the environment report, New Zealand saw a 42 per cent increase in net greenhouse gas emissions between 1990 and 2013.
The New Zealand government is bringing to Paris an Intended Nationally Determined Contribution target of reducing emissions by 11 per cent from 1990 levels by 2030. This has been criticised as insufficient by independent environmental monitors Climate Action Tracker.
The amount of already discovered reserves of oil, gas and coal that will have to remain in the ground to stay within safe limits for the climate.
