	abstract = {The number of publications on environmental footprint indicators has been growing rapidly, but with limited efforts to integrate different footprints into a coherent framework. Such integration is important for comprehensive understanding of environmental issues, policy formulation and assessment of trade-offs between different environmental concerns. Here, we systematize published footprint studies and define a family of footprints that can be used for the assessment of environmental sustainability. We identify overlaps between different footprints and analyse how they relate to the nine planetary boundaries and visualize the crucial information they provide for local and planetary sustainability. In addition, we assess how the footprint family delivers on measuring progress towards Sustainable Development Goals (SDGs), considering its ability to quantify environmental pressures along the supply chain and relating them to the water-energy-food-ecosystem (WEFE) nexus and ecosystem services. We argue that the footprint family is a flexible framework where particular members can be included or excluded according to the context or area of concern. Our paper is based upon a recent workshop bringing together global leading experts on existing environmental footprint indicators.},

The quantification of N footprints at production level can support decision and policy making in the economy, by raising awareness of different stakeholders such as farmers, industrial actors, businesses, governments and scientists on the global threats of anthropogenic activities. These stakeholders have responsibility to reduce the environmental pressures by continuous improvement of the production system through technology and innovation. N footprint is also a tool to inform consumers on the impact of their lifestyle choices on the N pollution, which is essential to share the responsibility in protecting the planet. Raising awareness to all stakeholders and consumers at all levels will help to reduce the N footprint.},
