A research conducted by the University of Edinburgh has revealed that plant leaves account for less than one per cent of the Earth's emissions of methane. The emission is said to be about 25 times more effectual than carbon dioxide at global warming.

It has been said that the results contrast with an earlier scientific study which had revealed that plants were accountable for generating huge quantities of the greenhouse gas.

According to the discoveries, it has been confirmed that trees are a functional way of equalizing greenhouse gas emissions, because it’s production of small quantities of methane is far compensated by their capability to store carbon from the atmosphere in their leaves, wood and bark.

It has been sad that to get the results, artificial leaves made from plant pectin was created by scientists and gauged the methane created when the leaves were exposed to sunlight.

Their results were combined with satellite data on the leaf coverage of the Earth's surface, ozone in the atmosphere, cloud cover, temperature, and facts on sunshine levels to aid to work out the quantity of methane created by all plants on Earth.

Dr Andy McLeod, of the University of Edinburgh's School of GeoSciences, stated, "Our results show that plant leaves do give rise to some methane, but only a very small amount - this is a welcome result as it allays fears that forestry and agriculture were contributing unduly to global warming”.
