"We extended this performance in 2020 by making progress on a number of our ESG commitments, including achieving zero fatalities at our operations and implementing additional health and safety measures to protect employees at our operations from COVID-19. We plan to extend this momentum through a number of upgraded ESG targets in the near and longer terms as well through the role our nickel and cobalt products and Technologies capabilities will play in reducing carbon emissions in the years ahead."
