<p dir="ltr">The Tyndall Centre is celebrating 25 years of research at the midpoint of the ‘critical decade’ for climate action in 2025, amid unprecedented global climate change challenges. To mark this milestone, a report and analysis has been published to reflect on Tyndall’s early energy scenario research, drawing lessons from the past to enhance our future impact.</p><p dir="ltr">Energy scenarios have long shaped policy feasibility and ambition. Reflecting on past scenarios with the benefit of hindsight allows for an evaluation of assumptions on plausibility and outcomes. Here this is used to explore what can be done differently in response to the urgency of contemporary climate challenges. As climate impacts intensify, we ask how energy research can better align with the commitments under the United Nations Framework Convention on Climate Change (UNFCCC) and raise levels of ambition to support those already on the frontline, as well as future generations.</p><p dir="ltr">This figure relates to the transport energy data featured in the published report, comparing scenarios published between 2002 and 2009 with levels of transport energy demand that have materialised by 2022 (the year for which the latest data was available). The figure only shows data for those scenarios where data was available.</p>
