The company has accumulated the carbon credits through its own energy-saving initiatives and the credits are now held at the Chicago Climate Exchange.

Providing the carbon credits, which specify that one credit is equal to one tonne of carbon, will mean that Austrian-based Ifra Expo will be completely carbon neutral.

Denis Leclerc, AbitibiBowater's vice president of sustainability and environment, said the move was a "significant agreement", both for AbitibiBowater and for Wan-Ifra.

The manufacturer has reduced its own greenhouse emissions per metric tonne of paper produced by 31% from 2000 levels.

Leclerc said: "In absolute terms, emissions are down by 52%, or 2.8m metric tons of CO2.

"That equates to removing 560,000 cars from the roads and reflects a company-wide focus on improved energy efficiency and on switching from fossil fuels to renewable energy sources."

AbitibiBowater is also hoping to become a carbon-neutral enterprise over the following months.

The company produces a range of newsprint, commercial printing papers, market pulp and wood products.

Ifra Expo is due to be held on 12-15 October in Vienna.

Chicago Climate Exchange operates the US's only cap and trade system for all six greenhouse gases.
