BrazilÂ´s commitments also include a long-term objective to achieve climate neutrality by 2050. Brazilâs updated NDC is broad in scope and includes a consideration of means of implementation and the implementation of mitigation and adaptation actions in all economic sectors. This contribution is communicated under the assumption that the implementation of the Paris Agreement fully respects the principles and provisions of the UNFCCC, in particular the principle of common, but differentiated responsibilities and respective capabilities. As a developing country, BrazilÂ´s historical contribution to the global problem of climate change has been small.
