We apply the mitigation hierarchy to our activities, looking for a positive overall balance of their impact on biodiversity.
The current economic growth model is the main factor behind the accelerated loss of biodiversity that has been proven to exist. Scientists estimate that species are being lost at 1,000 to 10,000 times the natural rate, and that 60% of ecosystem services provided to humans are degraded or are used unsustainably.
Recognition of the pressure of human activity on the biodiversity. Increased awareness of the economic costs this loss entails.
Governments make increasingly more demanding international commitments which aim to stop or significantly reduce the rate of loss of biodiversity, with the consequent creation of new legislation.
A society more informed and aware of efforts necessary for sustainable development which must be shared by everyone.
The increasing demand for transparency, accountability and willingness to share in the resolution of a problem that affects all humankind.
The external recognition of the company’s high performance facilitates access to credit and new markets with increasingly stringent rules in environmental matters.
The anticipation of risks, the promotion of good practices and the demand for collaboration with other entities allow the reduction of operating costs and improve environmental benefits, either by increasing the efficiency and effectiveness of processes, or by reducing the risk of delays in construction.
With our Biodiversity Policy we are committed to achieving a positive overall balance for the impact of our activities on biodiversity. Our actions recognize humans to be an integrated part of ecosystems and direct and indirect beneficiaries of different services and products on which we all depend.
We adopt local and adaptive participatory management models, in order to ensure greater long-term effectiveness.
Specific reports are regularly published about our performance in the environmental field (link to the sustainability report 2014).
We promote mitigation measures to maintain the structural and functional balance of ecosystems, taking advantage of favorable conditions for some species created by the reservoir.
As compensatory measures, we recover degraded water lines and build small reservoirs for water level stabilization.
In new hydroelectric projects, habitat fragmentation is compensated by the improved quality of neighboring habitats to ensure local survival of the affected species.
Examples of other compensatory measures are the preservation of artificial spawning, water line recovery downstream and the building of fish ladders.
Reduced electricity consumption from fossil fuels, minimizing the impact of acidifying pollutants and those responsible for acid rain (NOₓ e SO₂).
We chose fuels with lower sulfur concentrations and we have implemented denitrification and desulfurization systems.
New plants have cooling towers, thus reducing the water collected for cooling.
We ensure extensive monitoring of the collisions of birds and bats with the blades of wind turbines and the cumulative effect of these.
We limit any indiscriminate access that disturbs sensitive species and habitats.
We promote measures to minimize the environmental impact of different stages of wind projects: design, construction, operation and decommissioning of the project.
As a minimization measure, we detour paths to bypass more sensitive ecological areas.
We put signaling line devices to minimize birds collision.
We promote the isolation of overhead lines to avoid electrocution.
We ensure sustainable practices in the management of vegetation in buffer strips, so reducing or nullifying negative impacts on surrounding habitats.
