The Committee consists of nine members who look after the day-to-day affairs of LCANZ. These are:
Dr Barbara Nebel (President)
Barbara’s passion is to enable organisations to succeed sustainably. As CEO of thinkstep-anz she often describes her job as a translator. Translating sustainability into traditional business language. Together with her team, she delivers a full range of sustainability services from strategy and materiality assessments through to detailed Life Cycle Assessments and Cradle to Cradle® projects. Barbara has worked with organisations in New Zealand, Australia, Asia and Europe, effectively linking sustainability with business value.
As the founder of LCANZ, she initiated the Australasian EPD Programme. She is a member of the International EPD system and on the Steering Group for the Climate Leaders Coalition. Barbara has chaired the New Zealand working group for the development of ISO standards for Carbon Footprinting, is a Certified LCA Practitioner, and an associate editor for the International Journal of LCA.
John McArthur (Treasurer and Membership)
John spent much of his career in the Pulp and Paper and composite wood panel industries where he developed and managed the Quality and Environmental systems to ISO 9001 and 14001. In his EMS role in Laminex he took on the Climate Change data management role and developed this work stream for Fletcher Building, becoming their Carbon Reporting Manager and developing the enterprise-wide global reporting programme. In this time, John fostered a drive for LCA in many Fletcher Building business units, which led to John’s involvement in the LCANZ committee. John was instrumental in setting up EPD Australasia Ltd as one of LCANZ’s foundation board members and is now the Treasurer of that company.
Joanne Duncan (Secretary)
Joanne worked in the business sector, doing systems accounting and then followed her strong interest in the environment, studying for a Post Graduate Diploma in Environmental Management at Massey University. The study focused on life cycle assessment, zero waste, product stewardship and circular economy. Joanne considers life cycle thinking and analysis provide an important insight and the rigorous data to promote product stewardship. She is particularly interested in incentives which will encourage businesses and consumers to take responsibility for their impacts. She thinks education is critical to achieve this. She is a member of Aotearoa Zero waste, attending the annual waste huis to keep up to date and enjoy the company of like-minded people. She is hoping to volunteer at one of the waste hubs.

In his current role as Sustainability Manager, Israel oversees sustainability initiatives at both Pacific Steel & New Zealand Steel, is responsible for eco labels and EPD’s, and works closely with the wider BlueScope global sustainability team.
Israel contributes to the broader steel & construction sector through work on several boards and committees including the Metals NZ board, helping bring a unique perspective from the intersection of sustainability and manufacturing, to support the broader needs of the BC&I industry. This role combines his passion for sustainability and manufacturing and gives rise to opportunities for better collaboration between the hard-to-abate sectors with the wider building eco-system, to help deliver meaningful change.

Ray Mohan
Ray Mohan is an LCA and product footprinting specialist with a strong interest in food systems, agriculture, and circular approaches to resource use. She has over eight years’ experience working across the agri-food and manufacturing sectors, supporting organisations to understand their environmental footprints and identify practical, system-level opportunities for improvement.
She currently works as a Livestock and Environment Specialist with the Food and Agriculture Organization of the United Nations (FAO), contributing to the development of national livestock emissions baselines and the update of the Global Livestock Environmental Assessment Model (GLEAM). Her work focuses on applying lifecycle thinking to production systems, with particular attention to material flows and waste valorisation.
As Co-Chair of the LCANZ Best Practice Working Group, Ray is excited to contribute to strengthening good LCA practice in New Zealand and supporting the application of lifecycle and circular-economy thinking across our diverse industries.
Shreyasi Majumdar
Shreyasi is an environmental sustainability researcher and writer based on the Kāpiti Coast, Aotearoa New Zealand. She recently completed her PhD in environmental sustainability at the Life Cycle Management Centre, Massey University, with a focus on LCA applied to agri-food systems in New Zealand. Her research explored LCA-based indicators for sustainable food production and consumption. For the former, she focused on voluntary sustainability standards for New Zealand primary sectors, using the avocado sector as a case study. At the consumption end, she developed a nutritional LCA method to help consumers make more (environmentally and nutritionally) informed decisions at the meal level.
Shreyasi has over twenty years of experience as a writer and editor, having worked as a commodities journalist and then Group marketing and communications editor for a Danish environmental consultancy in Singapore. As a longtime committee member of LCANZ, she is keen to support knowledge sharing, interdisciplinary dialogue, and the wider uptake of life cycle thinking across research, policy, and practice.
