Researchers said Marsden Moor could hold the equivalent annual emissions released by one million cars.

A West Yorkshire moor stores carbon equivalent to the annual emissions released by a million cars, researchers have said.

Marsden Moor, a popular spot for tourists and walkers between Manchester and Leeds, is known for its blanket peat bogs stretching across the 2,300-hectare landscape.

To mark World Bog Day, a team from the University of Leeds geography school have released the results of a four-year study into the layers of peat across the entire estate.
