In 2017, the group reported that 30% of total electricity used in buildings was from renewable sources, up from the 28% reported in 2016. This represents a doubling of the proportion of green electricity use since 2008 and has led to the significant decrease observed in Scope 2 electricity emissions since the start of the programme (discussed in the Emissions Analysis: Scope 2 section). Seventeen posts out of the group of 20 now report some volume of renewable energy use, with the proportion varying between participants. Eight participants have now made the impressive transition to using 100% renewable electricity.
The growth in green energy consumption has resulted in a 51% reduction in emissions from electricity use in buildings from the 2008 baseline, a commendable achievement.
However, there remain 2.2m tonnes of emissions associated with non-renewable electricity use left to be reduced. We should expect downwards pressure on these emissions from structural changes, as national grids continue to increase the proportion of power derived from more sustainable sources. But as always, there are further opportunities available for participants, such as switching to a green electricity provider, or developing their own renewable energy supplies. By making the maximum reduction in Scope 2 emissions from electricity, combined Scope 1 and 2 emissions could be reduced by a further 25% of the 2008 baseline, in addition to the 30% reduction that has already been accomplished. We therefore continue to encourage and support participants in furthering their efforts to transition to purchased or self-generated renewable electricity in order to achieve immediate and substantial emissions reductions.
