Nova Scotia cleantech non-profit EfficiencyOne has a new member of its C-suite, and one who will be familiar to many in the innovation economy: former Volta chief executive Martha Casey.

Most recently the interim co-CEO of the International Institute for Sustainable Development, Casey spent three years at the helm of Volta, during which time she led a temporary pivot to digital startup support services in order to keep the Halifax startup hub operational during pandemic lockdowns.

She originally joined the IISD — a think tank the creation of which was spearheaded by late Prime Minister Brian Mulroney — as vice president for operations and business transformation, before partnering Nathalie Bernasconi-Osterwalder in the top job.

EfficiencyOne, meanwhile, was originally created by the provincial government in 2010 as Efficiency Nova Scotia, with the mandate to improve energy efficiency in the process. It offers a range of 24 programs meant to help people reduce their energy usage, such as via technology pilots, which it estimates collectively prevent about 1 million tonnes of greenhouse gas emissions annually.

“EfficiencyOne plays a critical role in helping Nova Scotia achieve its climate and sustainability goals,” said Casey in a statement. “I am excited to have joined an organization that translates research into action, and I am passionate about supporting our province to achieve our green energy goals.”
