Examples of our work


Environmental footprinting & LCA

Each product has an impact on the environment, such as CO2, land use and use of resources. Environmental footprinting, Life Cycle Assessment (LCA) and Carbon Footprinting are methods to investigate the environmental impact of products and supply chains. These methods give insights in possible (environmental) improvements in the supply chain.


Footprint reduction

Climate change being one of the most urgent challenges of our time. Society and businesses are looking for ways to define the contours of a sustainable world. Accordingly, more and more companies are joining programs to set sustainability targets. 

Sustainability Target Setting start with a complete analysis and reduction plan of GHG emissions of the entire value chain. A challenging task, which asks for profound knowledge of agri-food value chains, quantitative environmental analysis and acquires high-quality data.

Data solution


Advancing sustainability in the agri-food sector requires accurate and precise information. Blonk developed the Agri-footprint database to provide a thorough and consistent life cycle inventory (LCI) database for the agriculture and food sector. The database is widely used and implemented by the food industry, the Life Cycle Assessment (LCA) community, the scientific community, and governments worldwide.

We offer trainings and courses, also specifically designed for your organization - online or on location. 

Methodology & standard development

Environmental standards development

Measuring environmental sustainability can be a big challenge. Moreover, there exist many ways to calculate the environmental impact of a product or product value chain. Different companies use different methods and different background data. This makes it impossible to make fair comparisons between products for instance. It obstructs the way forward to create truly sustainable food systems. To tackle this challenge, we support industries and sectors to develop harmonized environmental calculation rules, based on the latest available international methodologies.
