Fuel consumption and electricity are the main contributors to the EMMS group’s carbon emissions, and therefore reductions result in substantial financial savings for the participants.

The business case for sustainability


Fuel consumption and electricity use are the most significant contributors to the group’s carbon emissions, and their reduction presents opportunities for participants to realise considerable financial gains. Indeed, in terms of own transport emissions, when compared to figures if emissions had remained constant the group has achieved an accumulated saving of 1.2 million tonnes of CO2 over the seven years of the programme. Using a conservative conversion factor for diesel, this equates to 446m litres of fuel saved over this time period. This represents a financial saving of €390m (US$432m).1,2


The group has achieved a significant reduction in electricity consumption since the start of the programme. Consumption has decreased from 9.95 TWh in 2008 to 7.96 TWh in 2015, which translates into an accumulated saving of 9.5 TWh over seven years. Using a conservative factor for the cost of electricity this corresponds to a saving of €889m (US$985m).3
