Meet the Speakers

Caixa is delighted to be taking part in an event as important as the Energy Summit. For us, in the Vice-Presidency of Sustainability and Digital Citizenship, one of whose missions is to effectively sponsor the just transition to a low-carbon economy, in which the companies present here and the market dialogue so much with us, such an important agenda of transformation towards a cleaner energy matrix for Caixa; for Brazil, greener and decarbonized.

Paulo Rodrigo de Lemos Lopes

Vice-President of Sustainability and Digital Citizenship at CAIXA
I think these three days were very important for generating these connections, but the best part is yet to come: the post-event, which is the relationships we’ve created here, the meetings we’ve already scheduled, prioritizing our main objective, which is to achieve the energy transition of our country and the world.

Fábio Rímoli

Executive Manager of Corporate Communications & ESG at ATVOS
I’m absolutely delighted to be here in Rio de Janeiro for three incredible days, filled with great conversations and wonderful presentations from business leaders, academics, policy makers and government representatives, who are discussing the green future and the actions being taken today to ensure a healthier future for us all.

Elizabeth Bramson-Boudreau

CEO and Publisher of MIT Technology Review
The Energy Summit inserts Colibri Capital into a much larger environment, aimed at building and collaborating in an ecosystem in our country for the development of the energy transition, and also opens doors for us to participate in future events.

Carlos Eduardo de Barros

Chairman of the Colibri Capital Group
I think one of the most striking things I’ll take away from this event is the different types of experts who joined us. We heard from technology professionals and people who know this region and its opportunities for innovation. It’s a very rich place to learn, connect and hopefully make collaborations and partnerships happen.

From MIT, we are very proud to be here today and to participate in this event with so many people committed to imagining how a greener future can be realized not just for Rio, not just for Brazil, but for the whole world.

Lars Frolund

Member of the European Innovation Council and Professor at MIT
The Energy Summit was super important for connecting the five ends of MIT REAP: government, big business, universities, startups and investors. In addition, we expanded the connections beyond the energy sector. We had companies here from the financial, mining, materials, IT, chemical, mobility, transportation and aviation sectors, the whole range of segments that will affect and be affected by the energy transition.

Hudson Mendonça

CEO of the Energy Summit
Our expectations of the results of the Energy Summit are enormous, as it creates an environment for members of government, academia, large companies, startups and investors to create connections, collaborate and generate business. What we hope is that wealth will be distributed from here.

The support of the Rio state government and also Petrobras was fundamental in making this all happen. And, of course, MIT, as the central figure in the distribution and production of the knowledge that circulates here, as the coat of arms, the heraldry of MIT says: “mens et manus”, the minds and hands that really make things happen.

André Miceli

CEO and Editor-in-Chief of MIT Technology Review Brazil
