Low emissions are just the beginning
Reducing carbon emissions in a growing business, particularly one which continues to expand its store network, is a challenge which Bunnings is stepping up to with a range of initiatives.
“We recognise that Bunnings has an important role to play in reducing carbon emissions and addressing climate change,” says Bunnings Managing Director Mike Schneider.
Bunnings first began trialling micro-generation projects back in 2009, including a renewable solar photovoltaic (PV) system at Belconnen in the ACT and wind turbines at Bunnings Port Kennedy and Rockingham in Western Australia. In 2014, a new generation solar PV system was installed at Bunnings Alice Springs in the Northern Territory. Building on its success, the system was expanded in 2019 from 100 kilowatts to 475 kilowatts and battery storage was introduced, meaning it is now producing up to 80 per cent of the store’s energy needs.
Bunnings is continuing to increase the generation of renewable power via solar PV installations across the network. During the 2020 financial year, 35 sites had solar PV systems installed, with 67 sites in total completed at 30 June 2020. A further 25 systems are scheduled for completion this financial year, as well as expanding solar capability to 10 pre-2018 installed smaller systems.
For the first time this year, Bunnings has decoupled emissions growth from store network growth, achieving a three per cent reduction on last year's emissions while continuing to expand the store network.
To accelerate energy efficiency across the store network, LED lighting is a standard inclusion for all newly built Bunnings stores and stores are being gradually retrofitted across the existing network. At the end of the 2020 financial year, 149 warehouses, 12 smaller format stores and three trade centres were using LED lighting. On a like-for-like basis, LED lighting has been shown to reduce energy consumption by more than 20 per cent per store.
During the year, daylight and motion sensor technology was trialled in conjunction with LED lighting, indicating energy consumption savings of 25 per cent. Daylight and motion sensors are to be integrated into selected future LED upgrades across the network.
Bunnings’ focus for the year ahead will be on evaluating technologies and design initiatives to drive greater energy efficiency and exploring other opportunities to reduce emissions across the store network.
