The goal of the Stewardship Council is to create a Sustainability Seal for the mining, production, and use of rare earth elements. Experts in various fields have been invited to weigh in on what this seal should include. You have released a draft of the Guiding Values, and now you will hear feedback from stakeholders on all sides. You will listen to their arguments and select the Guiding Values that are most practical and effective.

Carefully read the Rare Earth Sustainability Seal Guiding Values, which you have released for public comment, so you can identify the changes proposed by each group and address their concerns and suggestions. Then review the following questions, which you will ask each group during the Summit before developing questions of your own:

  1. The mining and production of rare earth elements can result in intense and long-lasting water and soil pollution, yet these elements are in high demand for countless modern technologies. Are there truly sustainable methods for mining and using rare earth elements? How can cleaner but more costly forms of production compete with cheaper mining operations and illegal smuggling? Who in the production cycle of rare earths should bear the burden of evaluating and minimizing environmental impact?

  2. Great strides have been made in the effort to efficiently recycle rare earth elements, but the science behind these technologies is still being tested and existing methods are not widely implemented. Is it possible to prioritize recycling and reuse in the demand for rare earths? What is the most effective way to create incentives for recycling and reuse to reduce new production?

  3. The goal of this Summit is to create a Sustainability Seal for the mining, production, and use of rare earth elements. What are the critical factors that must be addressed when discussing the sustainability of rare earths? What are the biggest obstacles to making rare earth elements a sustainable resource? What new problems might result from the creation of this seal?

  4. What historical examples and evidence provide useful lessons about the successes or failures of addressing the impact and implications of our use of rare earth elements?

  5. Do the problems caused by our use of rare earth elements outweigh the benefits that they provide?
