Tóm tắt	Scenario planning is a strategic-foresight method that develops a small set of plausible, internally consistent and divergent stories about how the future might unfold, in order to test policies and strategies against deep uncertainty. Rooted in the work of Pierre Wack at Royal Dutch/Shell and popularised by Peter Schwartz's The Art of the Long View, it does not try to predict the future but to expand decision-makers' thinking about it. By exploring several qualitatively different futures, policymakers can craft strategies that are robust across a range of possibilities rather than optimised for a single forecast that may not arrive.	Backcasting is a normative futures method that starts from a desirable future end-state and works backward to determine the policies, actions and milestones needed to reach it from the present. Coined and developed by John Robinson, who set out its logic in his 1990 article 'Futures under glass', it deliberately contrasts with forecasting: rather than asking what future is likely given current trends, backcasting asks what future we want and how we could get there. It is especially suited to long-term, transformative challenges such as sustainability and decarbonisation, where prevailing trends point away from where society needs to go.
