Furthermore, efforts are also required in the area of energy efficiency and energy conservation, as a way of reducing consumption, preventing additional electricity generation and reducing the emissions of greenhouse gases. The implementation of a National Energy Efficiency Policy will represent a reduction in electricity consumption of around 10% in 2030, equivalent to savings of 106 TWh, which can avoid emissions of 30 million tons of CO2 the same year, in a conservative estimate.  Energy Efficiency implementation of the National Policy for Energy Efficiency that will result in a gradual energy saving up to 106 TWh/year to be reached in 2030, avoiding emissions of around 30 million tons of CO, in that year.  Charcoal - consumption increase of sustainable charcoal to replace coal in steel plants, mainly through the encouragement of forestation in degraded areas.
