English: One-third of CO2 emissions from deforestation are embedded in international trade
In a study published in Global Environmental Change, Florence Pendrill and colleagues investigated where tropical deforestation was occurring; what products were driving this; and, using global trade models, they traced where these products were going in international supply chains. They found that tropical deforestation – given as the annual average between 2010 and 2014 – was responsible for 2.6 billion tonnes of CO2 per year. That was 6.5% of global CO2 emissions. International trade was responsible for around one-third (29%) of these emissions. This is probably less than many people would expect. Most emissions – 71% – came from foods consumed in the country that they were produced. It’s domestic demand, not international trade, that is the main driver of deforestation. In the chart we see how emissions from tropical deforestation are distributed through international supply chains. On the left-hand side we have the countries (grouped by region) where deforestation occurs, and on the right we have the countries and regions where these products are consumed. The paths between these end boxes indicate where emissions are being traded – the wider the bar, the more emissions are embedded in these products. Latin America exports around 23% of its emissions; that means more than three-quarters are generated for products that are consumed within domestic markets. The Asia-Pacific region – predominantly Indonesia and Malaysia – export a higher share: 44%. As we will see later, this is dominated by palm oil exports to Europe, China, India, North America and the Middle East. Deforestation in Africa is mainly driven by local populations and markets; only 9% of its emissions are exported. Since international demand is driving one-third of deforestation emissions, we have some opportunity to reduce emissions through global consumers and supply chains. But most emissions are driven by domestic markets – this means policies in the major producer countries will be key to tackling this problem. |
