We invest in energy efficiency projects in our plants, and we seek long-term partnerships in our purchase of clean energy. Currently, at least 74% of all electricity we purchase globally comes from renewable sources. We signed two contracts for the purchase of renewable energy in 2020: one for solar energy with Canadian Solar, and the other for wind power, in partnership with Casa dos Ventos. Since 2018, we have negotiated and signed four renewable energy purchase agreements that will avoid an estimated 1.5 million tons of CO2e. These agreements involve the construction of renewable energy generation farms, contributing not only to our own sustainable development strategy, but also improving Brazil's energy matrix, in addi- tion to bringing economic development to the regions where the solar farms are installed. Our Energy Efficiency Program was created in 2019 to acceler- ate energy initiatives and boost our competitiveness while re- ducing our CO₂e emissions. The initiatives aim to make Braskem one of the best chemical industries in energy consumption worldwide, and even during the pandemic we moved forward implementing them in several plants. In Bahia, the implemen- tation brought annual recurring savings of 833 GWh in energy consumed, equivalent to the annual electricity consump- tion of the entire state of Roraima with its almost 600,000 inhabitants. In addition, the initiatives also reduced 247,000 tons of CO₂e in the period, or 8% of the site's emissions. ENERGY CONSUMPTION (GJ/T) 2018 10.94 20191 While the coronavirus pandemic and the interrup- tion at the Chlorine-soda unit in Alagoas reduced our operational capacity, energy efficiency initiatives also contributed to lower energy consumption. 11.09 2020 11.23 The indicator for energy efficiency at Braskem units is calculated as the ratio between unit energy consump- tion for production processes and total unit output. This indicator is called energy intensity. The sum of the energy consumption volumes informed for each unit and the energy consumption reported in spreadsheet 302-1 is not the same. There are differences in the control volume considered in the respective calculation, in addition to other factors such as PCI, etc. The pur- poses are also different: the first is used to measure the improvement in energy efficiency at unit level, while the second serves accounting and financial purposes, includ- ing possible negotiations with the unit energy provider. The following graphics show consumption, type and source of energy at Braskem.
