Certification, True Pricing and Key Performance Indicators (KPIs) claim to lead the way to a more sustainable and circular agriculture. But how can you be sure labels and KPIs really help to realize a better climate, more biodiversity and a cleaner and more healthy environment? And who sets the goals and decides when they are being met?

We all want a sustainable agriculture that produces food with a minimum environmental impact on its environment. Certified standards such as On the way to PlanetProof stimulate sustainably produced food by creating a price premium and a preference amongst customers.

What do you measure?
Anyone can issue a certification mark based on a number of criteria farmers need to comply with and ticking the box. Rarely standard setters check whether the criteria actually impact environmental goals. They easily result in greenwashing. Sustainable palm oil standards claims to protect and improve biodiversity. However, even the most recent criteria don't require the monitoring of actual biodiversity, as they are means in stead of goals based.

Peter Leendertse, senior advisor and deputy director at CLM Research and Advisory (Culemborg, the Netherlands) helped to create the ‘On the way to PlanetProof’ label.
He will demonstrate how labels can assures proof for customers. He will discuss the role drones and sensors can play in a dynamic system monitoring actual goals.

Erna van der Wal, Head of Quality Assurance & Corporate Responsibility Aldi Nord in the Netherlands, will show the steps ALDI has taken to become more sustainable in fruits, vegetables and dairy by implementing PlanetProof. She will present an Aldi use case.
