That this House notes with interest and concern a contention by five senior ecology and energy scientists that the International Panel on Climate Change (IPCC) Fourth Assessment Report's conclusions on biofuels are `seriously and dangerously deficient' in understating their costs and pitfalls and that the IPCC has not revealed the basis for its claim that biofuel blending programmes or incentives in a number of national cases have been found environmentally effective upon initial inquiries; and therefore joins with the five scientists in calling on the IPCC to reveal the basis for this claim, in the interests of good science and to avoid prejudicing others' commendable work within the IPCC.
