Software consultancy TG Allison, for example, which helps dairy farmers in rural Wales maximize their milk yields, has cut average weekly mileage by its employees from 200 down to 40 miles — an 80% drop — at the same time as increasing productivity and customer satisfaction. Instead of spending hours driving out to a client’s farm whenever something goes wrong, the company’s staff now use an Internet link to connect to the farm’s computers and resolve the problem, often within minutes. Many farmers are also pleased to know the company has reduced its carbon emissions, says owner Thomas Allison.
