Yorkshire Dales National Park CO2 emissions slashed
Carbon emissions from buildings and vehicles owned by the Yorkshire Dales National Park Authority have almost halved since 2005, new figures show.
Energy saving measures had also cut costs by more than £300,000 over the same period, the authority said.
In 2005-06 its emissions totalled 701 tonnes of CO2 and in 2010-11 they stood at 385 tonnes - a reduction of 45%.
The authority said this was "substantially better" than the target it had set itself of 25% by March 2013.
It has invested in several projects, including a biomass (wood-fuelled) heating boiler at its head office in Grassington and a ground source heat pump at its Yoredale offices in Bainbridge.
Part of the Yoredale site has been built into a grass bank and has a grass roof to try to reduce the impact of the building. The grass layer also acts as natural insulation.
There have also been a number of smaller projects, ranging from energy saving improvements to buildings to fewer and lower-emission vehicles in the authority's fleet.
Staff mileage has also been cut by a fifth.
Finance officer Miranda Rickard said: "The measures we have put in place so far are now saving over 300 tonnes of carbon each year. That translates to a reduction in our energy costs of £59,000 per year."
