Gas and electricity accounts for around 40% of our carbon foot print and we have conscientiously tried to reduce this where ever possible. As an example our gas usage in 2014 reduced by 36% from measures put in place (loft insulation, draught proofing etc). Over recent years we have:
a) replaced halogen lighting with high efficiency LEDs.
b) replaced the kettle with an instantaneous hot/cold water tap
c) upgraded photocopiers, server and computers for more efficient models.
d) added a high speed internet connection for flexible working.
e) installed high efficiency replacement boilers and controls.
f) used an efficient off-site data storage system.
