The idea that to generate electricity should be considered climate-friendly has been debated by scientists and politicians for years. Advocates, including many scientists, ask what could be more sustainable than burning trees? They drink in planet-warming gasses while growing, and give it back up when they are burned — a perfect closed loop with no net emissions. Critics, on the other hand — including other researchers — say the science is much more complicated than all that, and that when managed poorly, woody biomass power could be worse for the climate than coal.

More than 125 academics have joined the International Energy Agency Bioenergy Technology Collaboration Programme (IEA Bioenergy) slamming Chatham House’s recent report on bioenergy, calling it ‘misleading.
The group of academics from across the world and the IEA state that the report “does not present an objective overview of the current state of scientific understanding with respect to the climate effects of bioenergy”.
They are urging the Chatham House author to “reconsider flawed policy recommendations.”

Using wood pellets to generate low-carbon electricity is a flawed policy that is speeding up not slowing down climate warming.
That’s according to a new study which says wood is not carbon neutral and emissions from pellets are higher than coal.
Subsidies for biomass should be immediately reviewed, the author says.
But the industry rejected the report saying that wood energy cuts carbon significantly compared to fossil fuels.

It took half a century for an acorn to grow into the 20-meter-tall oak tree standing here in a North Carolina hardwood forest near the banks of the Northeast Cape Fear River. But it takes just seconds to turn the oak into fuel for the furnace of a European power plant.
A logging machine—a cross between a tank and a one-armed crab—grabs the tree with a metal claw. With a screech, a spinning blade bites through the trunk. Ultimately, the thickest bits of this tree and hundreds of others from this forest will be sliced into lumber. But the limbs from large trees like this, along with entire small or crooked trees, go to a specialized mill to be squeezed into tiny wood pellets. Shipped across the Atlantic Ocean, they will likely end up fueling a giant power plant in the United Kingdom that supplies nearly 10% of the country’s electricity.

KLM Royal Dutch Airlines has signed a three-year contract with Los Angeles-based refinery AltAir Fuels and SkyNRG for the supply of sustainable biofuel on all flights between Los Angeles International Airport and Amsterdam Airport Schiphol.
The biofuel will be produced by AltAir Fuels and supplied by SkyNRG.
“Sustainable biofuel is currently one of the most effective ways to reduce CO2 emissions in the airline industry,” KLM president and CEO said. “Owing partly to the companies taking part in the KLM Corporate Biofuel Program, we have been able to take this step, giving a further impulse to the consistent production of biofuel.”
