New study suggests EU biofuels are as carbon intensive as petrol
Date:11/4/2011

A new study on greenhouse gas emissions from oil palm plantations has calculated a more than 50% increase in levels of CO2 emissions than previously thought and warned that the demand for 'green' biofuels could be costing the earth.

The study from the University of Leicester was conducted for the International Council on Clean Transportation, an international think tank that wished to assess the greenhouse gas emissions associated with biodiesel production. Biodiesel mandates can increase palm oil demand directly (the European Biodiesel Board recently reported big increases in biodiesel imported from Indonesia) and also indirectly, because palm oil is the world's most important source of vegetable oil and will replace oil from rapeseed or soy in food if they are instead used to make biodiesel.

The University of Leicester researchers carried out the first comprehensive literature review of the scale of greenhouse gas emissions from oil palm plantations on tropical peatland in Southeast Asia. In contrast to previous work, this study also provides an assessment of the scientific methods used to derive emissions estimates.

They discovered that many previous studies were based on limited data without appropriate recognition of uncertainties and that these studies have been used to formulate current biofuel policies.

The Leicester team established that the scale of greenhouse gas emissions from oil palm plantations on peat is significantly higher than previously assumed. They concluded that a value of 86 tonnes of carbon dioxide (CO2) per hectare per year (annualised over 50 years) is the most robust currently available estimate; this compares with previous estimates of around 50 tonnes of carbon dioxide (CO2) per hectare per year. CO2 emissions increase further if you are interested specifically in the short term greenhouse gas implications of palm oil production for instance und
