Is the New Zealand Government’s plan to ratify the Paris Agreement in 2016 consistent with a two degrees Celsius (2C) carbon budget?
Since the December 2015 Paris Agreement, the British climate scientist Kevin Anderson has given a couple of talks with the title Beyond Dangerous Climate Change: Does Paris Lock-out 2 Degrees?
Anderson’s message is that although the Paris Agreement was a diplomatic triumph, it relies on speculative utopian technological fixes (bio-energy carbon capture and storage) in the future in order to reconcile the now extremely limited carbon budgets consistent with the desired 2C (and 1.5C) temperature limits with business-as-usual economics and politics. In other words, the Paris Agreement locks out the 2C target.
Why do I mention that? Because I want to run a ‘Kevin Anderson’ ruler over the New Zealand Government’s recently announced ratification of the Paris Agreement. To conduct a bare assessment of New Zealand’s emissions taking account that it is the cumulative emissions that determine warming. I want to ask the question ‘does the New Zealand ratification also lock out any policies for emissions reductions consistent with a fair share of a 2 degrees Celsius carbon budget?’
