Our strategy, in and of itself, aims at expanding the use of natural gas, the main input for our generation plants and the cleanest of fossil fuels. In addition, interference in the atmosphere is evaluated from development-to-operation of the assets, through minimization, mitigation, control and monitoring actions. We developed specific studies to evaluate the support capacity of air basins, following the main atmospheric modeling methodologies recommended by the U.S. Environmental Protection Agency. Furthermore, air quality data prior to project installation is evaluated for backgroundanalysis. For impact mitigation purposes, our power generation assets have emission reduction equipment for NO, (Low- NO), and SO, abatement (desulfurizers - in the case of coal assets) and bag filters (in the case of coal assets). We also apply corporate procedure (PR.CRP.HSE.024 - Management of Atmospheric Emissions) which establishes the control, by the operating units, of atmospheric emissions, with the annual realization of emission inventory and adoption of control systems. Thus, we constantly are evaluating alternatives to reduce atmospheric emissions and/or the impact on air quality. The subject is addressed in internal and external audits, and the performance and compliance with the internal and legal limit are the subject of critical environmental analysis meetings, held at specific intervals with the participation of operational and corporate leaders. In 2021, the Brazilian electricity sector faced one of the sharpest scarce water crises ever recorded, causing a significant drop in the levels of the country's hydroelectric reservoirs. Faced with this scenario, the National Electric System Operator (ONS) requested that our thermoelectric plants be dispatched throughout practically the entire year, which offered greater security in the supply of energy. Hence, there was a natural increase in the emissions foreseen in the process. There was no violation of our legal limits and internal targets - more restrictive than Brazil's environmental legislation.

In gas-fired power plants, particulate matter is not an emission associated with the power generation process. sustainability report 2021 natural capital
