Initiatives

Clean AER

The Clean Atmospheric Emissions Reduction project (CleanAER) contributed to an 85% reduction in sulphur dioxide emissions at our operations in Sudbury, Canada. Other results are a 40% reduction of greenhouse gas emissions and 40% of metal particles.

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