VA Trees Make UK Power ECOLOGIST SETTING THE ENVIRONMENTAL AGENDA SINCE 1970

Brendan Montague April 16, 2018 A Dispatches investigation has uncovered evidence of hardwood forests being chopped down to provide 'green energy' for the UK. Experts say unique habitats rich in wildlife are under threat as Britain’s power stations switch from burning coal to wood, writes BRENDAN MONTAGUE If we take the forests and burn them the carbon dioxide goes into the atmosphere instantly, in a few minutes. It takes decades to a century to replace that.

Huge areas of hardwood forest in the state of Virginia are being chainsawed to create 'biomass' energy in Britain as the government attempts to reach targets to reduce greenhouse gas emissions in efforts to tackle climate change, an investigation by Channel 4 Dispatches has found.

A key part of government efforts to hit its green energy targets is to switch from generating electricity from burning coal to burning wood - or so-called biomass. It’s a policy that is costing taxpayers more than £700 million per year through a levy on their electricity bills.

The biomass industry and government argue that because wood is a renewable source of energy and trees can be replanted to reabsorb carbon dioxide this policy is good for the environment.

Simple experiment Antony Barnett, reporter at Dispatches, travelled to the southern states of the USA to investigate the source of wood that is now being turned into millions of tonnes of wood pellets to be burnt in Britain’s largest power station, Drax, in North Yorkshire.

Footage reveals huge areas of hardwood forest in the state of Virginia being chopped down and removed to a factory owned by US firm Enviva that grinds up logs into pellets. A large proportion of these pellets are then shipped across the Atlantic to be burnt at Drax in the UK one of Enviva’s main customers.

Britain has pledged to cut carbon emissions by 57 percent by 2030 and getting Drax to switch from burning coal to wood is meant to play an important part in that. Drax now produces up to 17 percent of Britain’s 'renewable' electricity, enough to power four million homes.

The power station giant claims that burning pellets instead of coal reduces carbon emissions by more than 80 percent.

However, Dispatches conducted a simple experiment at a laboratory at the University of Nottingham to compare the carbon dioxide emitted when burning wood pellets, similar to those used by Drax, instead of coal.

Dozens of scientists It found that to burn an amount of wood pellets that would generate the same amount of electricity as coal it would actually produce roughly eight percent more carbon.

Biomass is viewed as ‘carbon neutral’ under European rules. This means Drax is not obliged to officially report the carbon emissions coming out of its chimney stack. Dispatches calculated that if Drax were to report on the full extent of its emissions it would show that last year they amounted to 11.7 million tonnes of CO2.

Drax claims that the replanting of trees means all the C02 will be reabsorbed. But scientists argue that it will take decades for forests to regrow and subsidising biomass from wood pellets is fuelling an industry that’s making climate change worse in the short term.

Professor Bill Moomaw helped lead a team that won a Nobel Peace Prize for its work on climate change at the UN’s Intergovernmental Panel on Climate Change. He is one of dozens of scientists who have written to the British government, warning against this policy.

Professor Moomaw said in an interview with Dispatches: “If we take the forests and burn them the carbon dioxide goes into the atmosphere instantly, in a few minutes. It takes decades to a century to replace that.

Carbon absorbed “Britain may be on track to eliminating the use of coal but they are not on track to reduce their carbon dioxide emissions. We’re not going to meet our one and a half or two-degree targets that all governments, including the British government, agreed to in Paris.

"Burning more wood makes it absolutely impossible to meet that target. We now know that if we overshoot that the consequences last for 100s to a thousand or more years. So there’s no off switch, there’s no reverse gear.”

Andy Koss, chief executive of Drax Power, defended the policy of burning wood pellets in an interview with the programme: “I am very comfortable that all the material what we source meets regulatory standards in the UK and meets our very strict sustainability criteria.”

Koss said the site Dispatches had seen being logged was atypical and that the “vast majority” of its wood comes from residue and waste material. He said: “We’ve obviously looked at this as well. The site was a working forest, it was left unmanaged.

"The owner of that forest wanted to clear this using standard harvesting techniques to turn it back into a working forest. That forest is being regrown. We know the owner of that particular tract that will grow and there will be more carbon absorbed.”

Sustainability provisions On the question of Drax’s claim that by burning wood instead of coal it reduces carbon emissions by more than 80 percent, Koss admitted it didn’t include emissions from its chimneys: “We don’t count that. The government doesn’t count that.

"It doesn’t include stack emissions because if we are sourcing sustainable biomass from working forests, where this is more growth than is being harvested, we see the carbon as being reabsorbed.”

Envier said in a statement to Dispatches that it "works to industry leading, strict sustainability and wood sourcing policies and certifications."

It added: We will not work with any supplier that does not adhere to our commitment to protecting, nurturing and growing forests. Enviva does not accept wood from old growth or independently designated conservation areas. The small family owned site allegedly being shown in the footage is made up of younger trees = not the alleged 80 to 100 years - and is not a sensitive wetland forest.”

A spokesman for the Government’s Department for Business, Energy & Industrial Strategy told Channel 4: “Between 1990 and 2016, the UK reduced its emissions by over 40 percent. We have the most stringent biomass sustainability provisions in Europe.

"Environmentally friendly, low carbon bioenergy can help the UK to transition to a more diverse energy mix, increase our energy security, keep costs down for consumers and help us to meet our 2050 carbon targets.”
