EU consumption results in high carbon emissions from tropical deforestation, studies show

A sixth of all emissions resulting from the typical diet of an EU citizen can be directly linked to deforestation of tropical forests. Two new studies, from Chalmers University of Technology, Sweden, shed new light on this impact, by combining satellite imagery of the rainforest, global land use statistics and data of international trade patterns.

“In effect, you could say that the EU imports large amounts of deforestation every year. If the EU really wants to achieve its climate goals, it must set harder environmental demands on those who export food to the EU,” says Martin Persson from Chalmers, one of the researchers behind the studies.

The link between production of certain foods and deforestation has been known before. But what Martin Persson and Chalmers colleague Florence Pendrill have now investigated is the extent to which deforestation in the tropics is linked to food production, and then where those foods are eventually consumed. In the first study, they focused on how the expansion of cropland, pastures, and forestry plantations has taken place at the expense of the rainforest.


Emissions sources for deforestation-related carbon dioxide emissions are diverse and vary by region. Emissions embodied in production are shown for each commodity group within each region. A region’s width on the x-axis corresponds to the embodied emissions produced in that region, while the y-axis shows the share of emission attributed to each commodity group within each region, implying that the rectangles within the plot are scaled according to the emissions embodied in each region-commodity combination. The percentages within the rectangles indicate the share of the total embodied emissions; 2.6?gigatonnes of carbon dioxide due to tropical deforestation during the period 2010-2014.
