Abstract

The Paris Agreement provides an international framework aimed at limiting average global temperature rise to well below 2 ∘C, implemented through actions determined at the national level. As the Agreement necessitates a ‘net-zero’ emissions energy system by 2100, decarbonization analyses in support of national climate policy should consider the post-2050 period. Focusing solely on mitigation objectives for 2030 or 2050 could lead to blindsiding of the challenge, inadequate ambition in the near term, and poor investment choices in energy infrastructure. Here we show, using the UK as an example, that even an ambitious climate policy is likely to fall short of the challenge of net-zero, and that analysis of the post-2050 period is therefore critical. We find that the analysis of detailed, longer-term national pathways that achieve net-zero is important for future reassessment of ambition under nationally determined contributions (NDCs).
