Miscanthus is one of the most environmentally friendly means of producing biomass for renewable energy. Every tonne of Miscanthus that replaces coal, reduces up to two tonnes less of carbon dioxide added to the atmosphere, - creating a beneficial and sustainable impact on carbon emissions. Annual crops that use nitrogen fertiliser (derived from fossil fuels) compared, contribute just a small reduction in CO2 emission, when their energy and carbon footprints are accurately calculated compared to Miscanthus. This can be properly considered by accurate and independent LCA (Life Cycle Analysis)
