Lewis Rifkind, Mining Analyst (email)
B.Sc. in Civil Engineering
Lewis’ engineering background equips him well to produce recommendations for reducing environmental impacts of mining projects, and oppose mining projects with impacts that cannot be mitigated. Prior to becoming YCS’s Mining Analyst he was the Energy Analyst from 2000 to 2008. Lewis addresses environmental impacts associated with urban sprawl and general industrial development in the Yukon. Prior to his involvement with YCS, Lewis worked with the Raven Recycling Society dealing with public education campaigns around waste management. He has also worked with the Northern Climate ExChange at Yukon College developing community climate change adaptation plans. Lewis can be found most mornings holding court in the trendier downtown Whitehorse coffee shops.


Julia Duchesne, Outreach & Communications Director, Webmaster (email)
M.Sc. in Environmental Change and Management, University of Oxford

Julia is responsible for outreach and communications with YCS members, supporters, and the Yukon community, including the YCS website and social media channels. She also manages our Trail Guiding program and contributes to energy-related projects and the Peel Watershed campaign.
