Larger logging trucks give less CO2 emissions

The forest production chain’s emissions of greenhouse gases are very low. Most of these are CO2 emissions from on-road timber transport.

Wood fuels far less climate friendly than assumed

Burning wood or biofuels taken from slow-growing forests may actually be worse in terms of CO2 emissions than burning fossil fuels, new research suggests.
