The Paris Climate Agreement Has Been Adopted

The Paris Climate Agreement Has Been Adopted

After two weeks of marathon negotiations, 195 countries agreed today to approve an accord that would wean the world off fossil fuels this century, limiting global warming to 2ºC, with an aspirational target of 1.5ºC. It’s the first successful end to a global climate summit after two decades of failed negotiations.

The final draft of the text that forms the backbone of the Paris accord was supposed to be completed Friday morning, but negotiations ran long in light of numerous disputes over the wording of key passages.

Major sticking points included whether the world should limit its carbon emissions to prevent more than 2ºC of global warming — a widely recognised target — or whether a more ambitious goal of 1.5ºC of warming should be pursued. Developing nations and low-lying countries that are already feeling the impacts of climate change have made a strong push for the latter.

The final text is a bit of a compromise: the resolution calls on the world to hold “the increase in the global average temperature to well below 2 °C” and to pursue “efforts to limit the temperature increase to 1.5 °C.” But keep in mind that the world has already hit 1ºC of warming, and with the carbon reductions pledges countries have brought to the table, experts say we’ll be lucky if we hit the 2ºC warming target.

Another major point of contention in Paris has been financing. At the Copenhagen climate summit in 2009, it was decided that wealthy nations would shore up $US100 ($139) billion a year by 2020 to help the developing world decarbonise quickly. Developing nations have insisted that specific language needs to be included in the final text to ensure that this pledge is met. Ultimately, the $US100 ($139) billion figure appears only in the text’s preamble, not in any legally binding portions of the agreement.

Perhaps the most optimistic part of the final accord is an explicit long-term goal of net zero carbon emissions, to be met sometime in the latter half of the 21st century. Here’s that specific text:

Not everyone is 100 per cent happy with the final accord, but today’s unanimous vote of support is nonetheless historic, marking the very first time an agreement of this scope will be legally binding for all nations.

“Our text is the best possible balance,” French Foreign Minister Laurent Fabius said this afternoon, “a balance which is powerful yet delicate, which will enable each delegation, each group of countries, with his head held high, having achieved something important.”

Now let’s see if the world acts on it.
