Define the environmental impact of your product

The Ecolizer calculates the environmental impact of your product quickly and easily.  

The Ecolizer is an ecodesign tool and caters to all designers and companies who want to know and lower the environmental impact of their products. 

The Ecolizer calculates quickly and easily the environmental impact of your product. You can calculate the overall environmental impact, but also the impact of each phase in the life cycle of a product so you can tackle a life cycle phase with a high environmental impact. In addition to the analysis of a product, you can also compare the scores of products with each other.

On you can work with the Ecolizer for free and you can calculate the environmental impact of your product.

Ecodesigntool for designers

OVAM had this tool developed to make ecodesign more accessible for designers.

The Ecolizer is a simple but reliable source to base decisions on and to integrate ecodesign into the design process in a user-friendly manner.

Calculation of the environmental impact

The environmental impact is calculated on the basis of eco-indicators. The indicators summarise the environmental impact of materials and processes in one figure. All indicators were updated in August 2014. So you can now count with the most current indicators.

The calculation of the eco-indicator was done according to the ReCiPe method. For more information about the ReCiPe method, please visit

Scientifically based

The Ecolizer is a scientifically based tool that can contribute to increasing the environmentally sound nature of the design/product. In this way, OVAM hopes to provide a dynamic and current instrument that inspires national and international designers and companies to innovative and environmentally sound products. 

The data in the Ecolizer are based on international ecoinvent database. For more information on the ecoinvent database, please visit

VITO  performed the calculations using the software SimaPro. The calculation was done according to the so-called ReCiPe method. The ReCiPe method defines 19 environmental impact categories that are related to one accessible score.

On March 15, 2023, the Ecolizer will go offline

After 15 successful years, the Ecolizer is going offline. Thank you to all users!  

In 2006, the OVAM launched the first paper version of the Ecolizer. In 2009 came an update of the paper version under the name Ecolizer 2.0. From the end of 2012 there is an online Ecolizer that made calculations easier. And that turned out to be a good decision : the number of users of the online tool reached 11,787!  

We look back on our successful tool with much contentment. But the only certainty in life is that nothing is certain. The Ecolizer relies on ecoinvent data, the new licensing conditions make it no longer feasible to use this data. The Ecolizer also needs a thorough and major update so that it meets the criteria of the most modern online tools. The above is currently not realistic for us to implement. Therefore, the decision was made to take the Ecolizer offline on March 15, 2023.
