In the name of tackling climate change, the UK has become the largest importer of wood pellets in the world in just five years.
The UK's demand for wood pellets is set to break five million tonnes this year and perhaps 10 million within a few years, fuelling a growing global trade and vociferous debate between energy firms and NGOs.
Accounting methods mandated by government show burning wood in place of coal is shaving millions of tonnes off UK emissions, yet NGOs say separate government research shows the opposite.
So, does the UK's growing use of biomass for power generation help solve climate change or not? Carbon Brief guides you through the dense thicket of debate in search of answers.
