Aviation is one of the fastest growing sources of greenhouse gas emissions, with an 8 per cent leap reported in Europe last year and a global fourfold increase in CO2 pollution expected by 2050.
To rein this back, the industry has promised carbon neutral growth by 2020 – to be met by biofuels, if a blueprint is approved at an International Civil Aviation Organisation (ICAO) conference in Mexico City this week.
The “green jet fuel” plan would ramp up the use of aviation biofuels to five million tonnes a year by 2025, and 285 million tonnes by 2050 – enough to cover half of overall demand for international aviation fuel.
But this is also three times more biofuels than the world currently produces, and advanced biofuels are still at too early a stage of development to make up the difference.
Environmentalists say that the most credible alternative fuel source would be hydrotreated vegetable oil (HVO), even though this would probably trigger a boom in palm oil plantations and a corresponding spike in deforestation.
Klaus Schenk of Rainforest Rescue said: “Citizens around the world are very concerned about burning palm oil in planes.
The vast use of palm oil for aviation biofuels would destroy the world’s rainforests, the basis of life for local people and the habitats of endangered species such as orangutans. We urge ICAO to scrap its misguided biofuels plan.”
It is impossible to quantify the precise extent of deforestation that the proposal could cause, but based on the Malaysian Palm Oil Council’s crude palm oil yields and Total conversion figures, Biofuelwatch estimate that 82.3m hectares of land (316,603 sq miles) would be needed to meet the target, if it were sourced from palm oil alone. That is more than three times the size of the UK.
Carlos Calvo Ambel, a spokesman for Transport and Environment, said: “Most biofuels are worse for the climate than jet fuel. Quality should always go before quantity. Establishing a goal even before the rules are set out is putting the cart before the horse. The European experience has been that biofuels targets sucked in palm oil exports whose emissions were far greater than those of fossil fuels.”
T&E, Oxfam and Friends of the Earth are among nearly 100 environmental groups protesting the proposal, while 181,000 people have signed a petition calling for the initiative to be scrapped.
