What tiny Bhutan can teach the world about being carbon negative

Carpeted in forest, Bhutan absorbs more CO2 than it emits.

(CNN)High up in the Eastern Himalayas is one of the greenest countries in the world. While many nations are struggling to reduce their carbon emissions, the Kingdom of Bhutan is already carbon negative: it takes more greenhouse gasses from the atmosphere than it emits.

Sandwiched between China and India, Bhutan spans approximately 14,800 square miles -- roughly the size of Maryland. Its vast woodlands cover approximately 70% of the country and act as a natural carbon sink, absorbing carbon dioxide.
As a result, according to its own figures, this nation of around 750,000 people removes nearly three times as much CO2 as it produces.
    Bhutan's ability to be a net carbon sink is partly down to its natural forests and the fact that it is relatively undeveloped -- most people work in agriculture or forestry -- which means it emits less than 2.5 million tons of CO2 each year. Luxembourg, for example, with a smaller population, emits four times as much.
