Brazil submitted the document ratifying the Paris Agreement in September 2016, in which it committed to reduce GHG emissions by means of a Nationally Determined Contribution (NDC). The NDC targets to reduce GHG emissions by 37% in 2025 and 43% in 2030.1 The project ’Mitigation Options of GHG Emissions in Key Sectors in Brazil’, prepared in a partnership between the Ministry of Science, Technology, Innovations and Communications (MCTIC) and UN Environment, indicated a rationale that takes into consideration sector cost-effectiveness and key technologies for compliance with the NDC.2 However, it is necessary to establish a national consensus where Technology Action Plans can build from, aiming at developing local content of priority technologies and sectors for compliance with the NDC. Therefore, this proposal seeks to develop a comprehensive ‘Technology Needs Assessment for the Implementation of Climate Action Plans in Brazil’.
