Our Team

KAREN HAUGEN-KOZYRA (PRESIDENT) P.AG., M.SC.

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 who 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. Viresco Solutions provides clients from across North America with support from strategy and policy development through to project implementation and Measuring, Reporting and Verification plaftorms.

Karen obtained a Biological Sciences Diploma from NAIT, BSc in Plant Sciences and MSc in Soil Microbiology and Biochemistry from the University of Alberta. Karen is also a registered Professional Agrologist with the Alberta Institute of Agrology. Karen can be reached at [email protected].


Candace Vinke (Sustainable Development Director) M.A.

Candace has a Master of Arts degree in Geography from the University of Victoria and a Bachelor of Science degree in Geography from the University of Calgary. Prior to joining Viresco Solutions, Candace was the Manager of Agricultural and Social Projects with The Prasino Group. In this role she led a team of sustainability professionals working on consulting projects related to agricultural offset protocol development, greenhouse gas emission reduction quantification, environmental market policy and opportunity research (RFS2, LCFS, Carbon, Water Quality, etc.) and supply chain sustainability.

Previously, Candace has also worked in the non-profit sector, first as a Business Development Facilitator at Momentum, a community economic development organization offering business training and microloans to individuals living in poverty; and subsequently in Pucallpa, Peru as a Research Fellow with the World Agroforestry Centre / The International Institute for Sustainable Development (IISD). During her master’s she also had the opportunity to work in the Small Island Development States Unit within the Division for Sustainable Development in the Department of Economic and Social Affairs (DESA) at the United Nations Headquarters.

Common themes throughout Candace’s work have included climate change, environmental markets, poverty and inequality. In addition to her home country of Canada, Candace has worked and/or studied in Ethiopia, Egypt, Cameroon, Malawi, Kenya, Peru and Brazil. She can be contacted via e-mail at [email protected].

She has extensive experience in stakeholder consultation, facilitation and has received training in ISO 14064 related to greenhouse gas inventories, project quantification and verification, facilitation, project management, media training, and RETSCREEN. She can be contacted via e-mail at [email protected].


Jon Alcock (Sustainability Specialist) B.Sc.

Jon’s diverse scientific and research background has given him a well-rounded view of global sustainability issues and solutions, particularly within the fields of agriculture, energy efficiency and climate change. Jon’s work at Viresco has focused on market-based frameworks and financial mechanisms for ecosystems services and GHG emissions in the agricultural and land-based sectors, both in North America and internationally. Specific areas of interest include ecosystem conservation, bioenergy, agro-forestry, and agri-food value chain accounting.

Prior to joining Viresco Solutions, Jon worked in a range of roles for a variety of employers in the environmental sector:

• Working at the UK Environment Agency, Jon dealt principally with the agricultural industry, addressing impacts to water quality and quantity, promoting implementation of best management practices, and in flood mitigation, mapping and emergency response.
• As a researcher for the University of Bristol Glaciology Centre, Jon investigated climate change impacts on the Greenland Ice Sheet, designing sampling and data collection systems, and assisting in the analysis and presentation of results in three peer-reviewed papers.
• Jon has managed energy efficiency projects for both an environmental charity, and a bio-industrial and crop research company, working with public, UK government and the brewery industry.
• In Alberta, Jon has worked as an aquatic biologist, consulting on oil and gas pipeline and construction projects, and as a field researcher and lab technician for the Alberta Biodiversity Monitoring Institute (ABMI).

Jon has a Bachelor of Science degree in Environmental Sciences from the University of East Anglia, UK, and the University of Calgary. For his thesis, Jon combined toxicology experiments and climate change forecasts to model the impacts of climate change on the resistance of four pine tree species to bark beetle attack, and changes in tree range as a result.

Alicia Klepfer (Sustainability Specialist) M.Sc.

Alicia Klepfer joined Viresco in August 2016 as a Sustainability Specialist. Alicia began her environmental career with a B.Sc. in Environmental Science from the University of Chicago in 2014. Originally from Colorado, Alicia returned to the Front Range and pursued research with Dr Stephen Ogle at the Natural Resource Ecology Lab at Colorado State University. With Dr Ogle she coded a simplified CENTURY model in R to run global agricultural soil carbon equilibrium runs over a 10 year period with incorporated uncertainty measurements, as well as working on a variety of other agricultural meta-analyses and other research projects. Alicia was then accepted into the first cohort of CSU’s MGMA program (Masters in Greenhouse Gas Management and Accounting). Following three semesters of coursework, she met part of the Viresco team at a conference and completed an internship as part of her degree program. Additionally, Alicia has worked on piloting nitrogen rate reduction offset project development with our sister organization, Climate Smart Group. Alicia has a broad view of environmental issues and has been focusing specifically on agricultural insetting, comprehensive understanding of research literature, and writing various reports on GHG mitigation options and offset protocols.
