Further Climate Change Legal Professionals to Follow on Twitter

This is, of course, just a small selection of the great many people out there specialising in climate change law and environmental law, who are all helping turn the tide on climate change.

See point 28 above, where Harro van Asselt tweets a very helpful expanded list of people he recommends you follow and connect with.

Many thanks also to Kristin Casper, Greenpeace International’s Senior Legal Counsel for Strategic Litigation, who shared these further recommendations of who she considers to be her climate law heroes:-

And thanks very much also to Dr Seán Doolan for pointing out his expanded list here:-

And others here:-

(Translation: List with 35 profiles of legal experts on climate change. And look how great: there are 2 Brazilians on the list! @JoanaSetzer, incredible researcher at @GRI_LSE, and @caiosborges, lawyer and super articulator on the subject of climate disputes by @climaesociedade.)

Climate Change Legal Influencers on Twitter Beyond the Western World

Director of the Centre for Intl Law at the National University of Singapore (NUS) and Member of UN International Law Commission, Nilufer Oral rightly asked what influence there is on Twitter outside of the Western World – another reason the original list of 35 above needed to be expanded:-

With that in mind, the list above (points 37 onwards) is a start to this – if any can provide further suggestions to provide a truly global representation of legal sector climate influencers that would be much appreciated (bearing in mind also that this list is only (and hopefully) going to keep growing significantly soon.

Keep in touch
