Positive and negative tipping points
The Climate Briefing

How is Trump 2.0 affecting the renewable energy industry?
The Climate Briefing
Trump 2.0 poses a huge challenge for the renewable energy industry in the US. Not only has the administration rescinded environmental incentives and regulations with bearing on future projects, it has also in various ways delayed and/or obstructed offshore wind projects already under construction (like the Empire Wind and the Revolution Wind projects). What does all of this mean for the renewable energy industry in the US? What does it mean for US competitiveness and the global energy transition? In the introduction, Anna is also joined by Chris Aylett, a Research Fellow at Chatham House's...

info_outlineCritical raw materials - like rare earths, cobalt and lithium - play a central role in the energy transition and profoundly influence geopolitical dynamics. Their extraction may also amplify conflict and fragility risks in host countries. In this episode of the Climate Briefing, Ruth and Anna speak to Olivia Lazard (Fellow at Carnegie Europe) and Sophia Kalantzakos (Global Distinguished Professor, Environmental Studies and Public Policy, NYU Abu Dhabi) about the interlinkages between critical raw materials and geopolitics, the challenges associated with extraction, and what a ‘good’ strategy for securing future access might look like.
