HE DVLA has had to pay a carbon tax of nearly £200,000.
The Morriston-based organisation is one of many signed up to the UK Government's mandatory carbon reduction commitment scheme.
The sum payable is based on its carbon emissions in 2011/12, which is in turn based on energy usage.
The DVLA has introduced energy-saving measures such as new LED and low energy lamps, and new steam humidifiers.
It also plans to install new boilers by 2014.
