Nitrogen pollution, climate and land use: Why what we eat matters
Date:4/25/2014

A new report quantifies for the first time how much our food choices affect pollutant nitrogen emissions, climate change and land-use across Europe.

The executive summary of the European Nitrogen Assessment Special Report on Nitrogen and Food, 'Nitrogen on the Table', was released today (Friday 25 April 2014). The Special report provides an assessment of what would happen if Europe were to decrease its consumption of meat and dairy products. It shows how much cutting down on meat and dairy in our diets would reduce nitrogen air and water pollution, and greenhouse gas emissions, while freeing up large areas of farmland for other purposes such as food export or bioenergy. It also considers the health benefits of reduced meat consumption. The full report is published next month.

Report lead author Henk Westhoek, program manager for Agriculture and Food at PBL (the Netherlands Environmental Assessment Agency) said, "The report shows that the nitrogen footprint of meat and dairy is considerably higher than that from plant-based products. If all people within the EU would halve their meat and dairy consumption, this would reduce greenhouse gas emissions from agriculture by 25 to 40%, and nitrogen emissions by 40%. The EU could become a major exporter of food products, instead of a major importer of for example soy beans."

The work has been conducted by the 'Task Force on Reactive Nitrogen' of the United Nations Economic Commission for Europe (UNECE). In 2011 the Task Force produced the first 'European Nitrogen Assessment' (ENA) which showed that better nitrogen management will help reduce air, water and soil pollution, greenhouse gas emissions, simultaneously reducing threats to human health, biodiversity and food security.

Co-author of the report Prof Mark Sutton, an Environmental Physicist at the UK's Centre for Ecology and Hydrology, said, "Human's use of nitrogen is a major societal challenge that links environment, food se
