Clean AER


Clean AER

The Clean Atmospheric Emissions Reduction project (CleanAER) contributed to an 85% reduction in sulphur dioxide emissions and a 40% reduction in metal particulates at our operations in Sudbury, Canada. Another important result was a 40% reduction of greenhouse gas emissions from the Smelter.

Finished in 2018, Vale’s investment is historic: The total investment is US$ 792 million and shows the importance of sustainability in our actions.

The completion of our Clean AER Project is a historic milestone that demonstrates how far we have come as a company in reducing our environmental footprint. It is something that all of us at Vale and our local community can be very proud of.

The project started in 2012 and, as of May 2018, the sulfur dioxide gas leaving our company operations in Sudbury began to pass through a wet gas cleaning, which, prevent it from going through the chimney to the environment.
