Briefings
ECIU Briefings distil the often complex issues of climate science, energy policy and economics into straightforward language. They are written by specialist journalists, checked by experts in the relevant field, and updated with the latest significant developments.
We aim for 100% accuracy, but if you believe that you have spotted an error or a development that we have not reflected, please contact us.
We will be rolling out more Briefings over the coming months to tie in with current issues and events. If you would like us to provide a Briefing on any particular topic, again please contact us.
