Today, Brazil and many countries around the world are seeking to stimulate economic recovery and improve people’s quality of life. In this context, the Economic Commission for Latin America and the Caribbean (ECLAC) of the United Nations has been developing the Big Push for Sustainability, a renewed approach to support the efforts of the countries of the region to design more sustainable development models, by coordinating policies to promote investments that will transform existing models. The ECLAC office in Brasilia and the Center for Strategic Studies and Management (CGEE), in conjunction with various partners, developed the Energy Big Push Brazil project, which provides evidence to promote innovation investments for a sustainable energy transition in Brazil. This publication aims to enhance readers’ understanding of the energy innovation investment landscape, the performance of low carbon technologies and the policy framework for building clean energy technological competencies, contributing to an energy big push in Brazil.
