The result was a benchmark map of biomass carbon stocks covering 2.5 billion hectares (9.65 million square miles) of forest in 75 countries on three continents.

Saatchi is most proud that the map not only assesses carbon stocks, but also gives a picture of the quality and certainty of the assessment.

Forest conservation activities or activities avoiding deforestation, which would result in emission reduction through the conservation of existing carbon stocks, are not eligible at this time.

This is particularly true if the feedstocks used to produce the fuels are grown on land which previously held high carbon stocks such as forest or peatland.

Another difficulty for some kinds of carbon sequestration efforts is that of monitoring and accounting for carbon stocks.

The risk is that baselines are set unrealistically by developing country authorities and it's not actually accurate around the forest's carbon stocks.

As defined, its aims are directed toward forest conservation, sustainable forest management and the enhancement of carbon stocks.

In order to meet these objectives, policies need to address enhancement of carbon stocks by providing funding and investments in these areas.

Encourage mechanisms that recognise the value of carbon stocks and forest ecosystem services, and support appropriate voluntary carbon market standards.

Of all global terrestrial carbon stock, 15.2% is contained within protected areas.
