Brazilian mining giant Vale is moving to address concerns and reduce its emissions by a third by 2030. As part of its efforts, experts from the MIT Environmental Solutions Initiative are contributing to the company’s Mining Innovation in a New Environment programme. We ask the MIT team about the keys to nurturing a sustainable mining culture.

We also hear from Energy Fuels' CEO about the role the White Mesa Mill has to play in the US' rare earth ambitions, speak to Everledger about eliminating conflict diamonds with blockchain, and talk to Kognitiv Spark about the future of mixed reality in mining.

We also examine how mercury can be mined and used safely, learn about the Future of Resource Taxation initiative, sit down with HUBER+SUHNER to find out about the importance of fibre optics, and look at the political aspects of the rare earths market.
