Flew on Monday to Sao Pãulo and then Brasilia, for a major sustainability event held by CNI. Wonderfully well hosted by Daniela Cestarollo of CNI (Confederação Nacional da Indústria). Did a well received 2.5 hour session with Marcos Troyjo, Director of the BRICLab at Columbia University, on Wednesday morning. Back into London earlier today, having finished off Omar El Akkad’s American War as I flew. Brilliant, dystopian view of the future of the USA.
