The carboNZero programme and CEMARS programme are the world’s first internationally accredited greenhouse gas (GHG) certification schemes under ISO 14065. They provide tools for organisations, products, services and events to measure and reduce their greenhouse gas emissions (otherwise known as carbon footprint), and optionally offset it. The programmes are owned and operated by Toitū Envirocare - Enviro-Mark Solutions Limited, a wholly owned subsidiary of Landcare Research (100% NZ government-owned).
