When staff in the Yorkshire Dales were planning a new national park head office in 2006, naturally they wanted to make it as energy efficient as possible.
So the new building, named Yoredale and situated just down the road from the previous headquarters in Bainbridge, is very well insulated.
One part of the complex, the meeting room, has been built into a grassy bank and has a hay meadow on its roof.
This provides it with natural insulation and also helps reduce the building's impact on the landscape. It also provides grazing for local sheep!
Other green features include having a ground source heat pump built under the new car park, which extracts warmth from the soil for the building's underfloor heating, and using locally-sourced stone wherever possible.
Recent work to combat climate change in the Yorkshire Dales National Park includes a scheme to 'plug' drainage channels (known as grips) to help reduce the amount of water draining out of the Park's peat soils.
It's part of the work being undertaken by the Yorkshire Peat Partnership (see below).
Blocking the grips helps slow down the flow of rainwater off the hills so that the moors can go back to their natural role: acting like a giant sponge peat soaks up rainwater and carbon. As the water table rises it encourages the growth of sphagnum moss, which actually starts to take carbon dioxide out of the atmosphere - eventually forming new peat.
The Yorkshire Peat Partnership is working with moorland owners to restore and then conserve huge swathes of upland peatland habitats.
As well as the Yorkshire Dales National Park, members of the Partnership are the Yorkshire Wildlife Trust, Natural England, National Trust, Environment Agency and North York Moors National Park Authority.
It also receives support from Nidderdale AONB, Pennine Prospects, the Environment Agency, the National Trust, the Moorland Association, the National Farmers Union and Yorkshire Dales Rivers Trust.
The innovations at the Yoredale office has saved the Authority:
