The Climate Change Committee (CCC) recommended the UK's 2050 Net Zero target in 2019 and then the emissions pathway to this as part of its advice on the Sixth Carbon Budget at the end of 2020. As part of this, the CCC's analysis included development of five pathways to Net Zero, incorporating a number of judgements and framings regarding uncertainty and decision points, to highlight key choices for Government and wider society on the path to Net Zero. This paper explores how the analysis, and its presentation, framed these choices and uncertainties, in order to highlight where decisions are required and what the trade-offs and potential contingency options might be. It concludes with reflections on the effectiveness of this approach and on the future challenges on decision-making and uncertainty toward Net Zero.
