Our Team



Karen has over 25 years of experience in agricultural greenhouse gas measurement, modeling, and climate change/environmental policy development – spanning her tenure at the provincial Department of Agriculture in Alberta, then at the not-for-profit Climate Change Central, and now in the private sector. During her tenure with the province, Karen was part of the cross-governmental team that developed Alberta’s Bioenergy Policy Framework, which was approved by cabinet in 2008. This framework set the stage for Alberta’s Bioenergy Program administered by the Department of Energy. Karen also led ecosystem goods and service policy and program development, in concert with other federal, provincial, and territorial governments under Canada’s Agriculture Policy Frameworks. In her earlier years with the provincial department of agriculture, she conducted research and studies of environmental mitigation opportunities for agriculture in air, water, soil and biodiversity

Her most significant contribution while she worked in the public and not-for-profit sectors was her work at a national level, with federal-provincial and territorial governments on the Canadian National Offset Quantification Team (NOQT). Karen, through her capacity on the Team, designed the protocol development process, represented the agricultural sector in Canada, and coordinated the development of several agricultural quantification protocols. In 2007, Karen was seconded to Climate Change Central, a not-for-profit established by the Government of Alberta. There, Karen led the implementation of the necessary market processes, infrastructure, and tools needed to get the Alberta Carbon Offset Market off the ground. In that role, Karen and her Team leveraged the previous NOQT work to help build sound rules, platforms, science-based quantification protocols, tools, and infrastructure (e.g. registry) needed to facilitate the development of a Carbon Offset Market in Alberta.

Currently, Karen is President of Viresco Solutions Inc. – a network of leading advisors making sustainability real for public and private clients in the agriculture, energy, and food sectors across North America and globally. Our team of experts enables our clients to meet their environmental, social, and economic sustainability objectives by leveraging our knowledge and experience in environmental policy, markets, and economics.
