Understanding transition scenarios – Eight steps for reading and interpreting these scenarios


It therefore brings risks and opportunities for economic actors, which they must anticipate in order to optimise their strategy in a context of uncertainty. Against this backdrop, the use of scenarios – which are plausible representations of uncertain future states – is very useful in order to better understand the medium- and long-term challenges of the low-carbon transition, and was in particular recommended by the TCFD (Task Force on Climate-related Financial Disclosures).

Before using scenarios, it is essential to know how to correctly interpret them. This implies first navigating the complex ecosystem of climate-related scenarios and identifying those that can be used to explore issues linked to the low-carbon transition: transition scenarios. It also requires fully understanding the issues relating to these scenarios.

The goals of this publication are therefore:

  • Explaining the key concepts underpinning climate-related scenarios, presenting the main families of scenarios and the questions these scenarios help to answer;

  • Providing keys to reading transition scenarios in order to facilitate their interpretation and to avoid misunderstanding.

A framework for reading transition scenarios was developed to provide readers with a step-by-step guide to scenarios. It summarises the eight main steps to follow in order to interpret a transition scenario according to the explanations developed in this study, and is applied to 5 publicly-available scenarios.

    World bank: what to expect from the Spring Meetings

    This is it. In a few days, thousands of people from around the world will be gathering in Washington to look back on the latest achievements and discuss the future of the World Bank and the International Monetary Fund – the two institutions that structure international cooperation for development. But this isn’t just one of a series of biannual get-togethers. These Spring Meetings will be the last for future ex-President of the World Bank David Malpass, who is leaving at what might be a turning point for the institution’s history. The expectations are high: this is the moment where the World Bank’s shareholders will confirm their vision and ambition for the institution by officially including climate in its global mission

    Ambition is the Key Missing Ingredient in the World Bank’s Paris Alignment Approach 

    After years of waiting, the World Bank finally approved and released its alignment approach with the mitigation and adaptation goals of the Paris Agreement. Presented by the World Bank as “the most comprehensive institutional undertaking ever done by the Bank Group to reconcile development and climate”, this alignment approach is an important step towards the reform of the World Bank currently under discussion. But this approach won’t be sufficient, argue Alice Pauthier and Sarah Bendahou in this blog post. It could be more ambitious.

    World Bank’s reform: almost a new pilot onboard

    After the sudden resignation of David Malpass, the World Bank’s Trump-appointed President, mid-February, Washington surprised the world again last Thursday, with the nomination of Ajay Banga, long-time Mastercard CEO, as his potential successor. Not only was the timing very rapid, but the controversial profile of the nominee also generated some sense of puzzlement. His limited […]
