Responsible Raw Materials is a global movement, focused solely on making the extraction, production and consumption of raw materials truly responsible. To do this, our challenge is to engage with people from every background, across every country, in order to understand as many impacts from as many perspectives as possible. We believe in open communication, through accessible and diverse forms of communication.

Driving this movement are Sarah Gordon and Rose Clarke, with a global team of dedicated volunteers, supporters and sponsors.

Dr Sarah Gordon - Co-founder

Dr Sarah Gordon completed her undergraduate in Earth Sciences at the University of Glasgow and PhD in the chemistry of meteorites at Imperial College London. She went to work for Anglo American, living and working in Canada, Brazil, southern Africa and Europe in roles including: Exploration geology, Sustainability, Safety and Risk & Assurance. It was during this time she became passionate about ensuring that we manage our raw materials in the most responsible way possible. In 2014 Sarah co-founded Satarla, the boutique risk management company that specialises in sustainable, enterprise-wide risk management. Sarah has also been a trustee of The Geological Society of London, Geology for Global Development, an honorary visiting lecturer at Imperial College London & research associate at the University of Johannesburg. Voted as one of the most inspirational women in mining in 2016,

Rose Clarke - Co-founder

Dr Rose Clarke completed her PhD at the University of Leicester, working alongside industry and with the British Geological Survey to investigate the geology and sustainability of gold deposits enriched in critical metals. She has an interest in sustainability and responsibility within geosciences and mining more specifically, and has undertaken a number of outreach and education projects based on this theme with Girls into Geoscience and the Brilliant Club. Rose is a climate change and ESG consultant at Satarla, working primarily with mining companies. Some of her research with Satarla has been looking into the concept of ‘responsible reserves’ and how this may be implemented.

Joshua Warner

Josh is a third-year university student at Imperial College London studying Earth and Planetary Science. He undertook an Undergraduate Research Opportunities Placement where he looked into deriving sustainability indicators from material flow analysis of Copper and Nickel in the Philippines, and from that discovered an interest in resource management, mining, and social policy. Josh joined Responsible Raw Materials in the winter of 2020 as a volunteer and helps produce the newsletters. Sign up if you haven’t already!
