Hidromaule has committed to reduce it’s carbon dioxide (CO2) emissions. Thanks to clean energy production, gas emissions are reduced to a equivalent of taking 22.000 cars off the road.

1. Market of Carbon Credits 
Market of Carbon Credits is one of three international mechanisms of decontamination developed during the Kyoto Protocol to reduce global warming.

Countries can trade in the international carbon credit market, so if a company exceeds the emissions it may have to pay or get credits on the open market from organizations that have been aproved.

Hidromaule has registered Lircay Hydroelectric Project as Clean Development Mechanism (CDM), according to the United Nations Framework Convention on Climate Change (UNFCCC). This international agreement entered into force in 1994. The objetive is to stabilize greenhouse gas concentrations in the atmosphere to not endanger human life and ecosystems.

The CDM are concretes measures developed by nations and companies with the purpose of reducing emissions. Hidromaule is doing the same process than Mariposa Hydroelectric Project. In this way, Lircay Hydroelectric has reduced by now 90 tons of CO2 per year, which 60 thousand have been decreased under the Verified Carbon Standar (VCS) and 30 thousand from Clean Development Mechanism (CDM). Meanwhile, it is estimated that Mariposas Plant will reduce 21 thousand of CO2 tons per year.

2. Non Conventional Renewable Energy Credits
In April 2008, Chile enacted the Non Conventional Renewable Energy (ERNC) law 20.257. This law allows Hidromaule to sell NCRE sources with the aim of helping to reach the quota that the law requires to produce this type of energy.

In this way, Hidromaule gives to Central Interconnected System (SIC) around 160 GWh of energy from clean sources per year. This, of course, contributes to a much healthier environment.
