ICO2 demonstrates the Companies' commitment to the transparency of their emissions and anticipates the vision of how they are preparing for a low carbon economy. The new portfolio will bring together 62 shares from 58 companies.

For this 2019 cycle, the proportion of 0.0122 tCO2 / R$ thousand in emissions was recorded. It is also worth mentioning that Copel has been a signatory to the United Nations Global Compact since its constitution and acts to achieve the 17 Sustainable Development Goals (“ODS”), primarily in ODS 13 - Action against Climate Change, specifically in business in that acts.
