KPN Business Market has donated EUR 100,000 to the World Wide Nature Fund (WWF) to support the project Atlantic Forest. KPN donated EUR 1 for every customer who opted in to receive electronic invoices and opted out on paper invoices. At this pount around 85 percent of customers are now on e-invoices, saving each business customer an average 50 pages of paper each year. KPN said this saves it 650 tons of CO2 emissions. And it saves KPN around € 6 million a year. Quite a successful e-invoicing campaign. Something tells me that EirCom could learn from this.
