Not quite, a peat bog is a carbon sink that actively collects the carbon from the environment and locks it up, then over millions of years it sinks down further in to the ground and is burried. Eventually it will become coal.

Digging up peat does something that digging up fosil fuels like coal and oil doesn't, it is destroying a natural environment that cannot be replaced. Adding carbon to the atmosphere through burning coal, gas and oil is one thing, but destrying an irreplaceble resource that is helping to reduce this carbon is very different. Without it, the environment can't 'landfill' excess carbon.

I don't even aprove of digging it up to replace wetlands. In fact, I think we should be researching ways to create artificial peat bogs as somewhere to dispose of all the extra carbon from burning fossil fuels.

Buying peat is a personal choice, but I don't recomend it, and the fact that some people are buying it doesn't make it right or our smaller garden usage less significant.
