Mersey Tunnels go greener

An environmental upgrade of the three Mersey road tunnels has saved more than 3,000 tonnes of CO2 from being pumped into the atmosphere, tunnel operator Mersey Travel said this week.
Converting the tunnels' ventilation fans to a variable speed drive has cut electricity consumption by 10%. Mersey Travel has also switched to electricity from Combined Heat and Power. 'We place great importance on our environmental responsibilities in all aspects of our business and we were the first transport authority to develop an environmental sustainability strategy,' said chief executive and director general of Mersey Travel, Neil Scales. 'To put these figures into perspective we have cut enough carbon emissions compared to three years ago, to fill 18,978 double-decker buses with CO2.'
