The graph below shows how these two intensity metrics have varied between 2016 and 2018.  As can be seen these trends mainly demonstrate a gradual reduction in emissions intensity over time and therefore an improvement in the energy efficiency of our estate. The notable increase in the tCO2e per £m revenue in 2018 is mainly attributed to a reduction in overall revenue as opposed to an increase in GHG emissions. The GHG footprint of the estate has improved despite the reduction in revenue and an increase in employees.
