Norway, June 19 -- Hydro's alumina refinery Alunorte in the state of Para, Brazil invested BRL 1.3 billion to avoid around 700,000 tonnes of carbon emissions annually.

Replacing fuel oil with natural gas at Alunorte is a significant step in the decarbonization journey. Natural gas emits up to 50 percent fewer greenhouse gases and air pollutants compared to sources like oil and coal, contributing to improved air quality and climate change mitig...
