Yes. Most of our GHG emissions from operations are related to the energy used to power our facilities. To save money, drive progress toward our goals, and reduce our climate impacts, we:
- Aggressively reduce energy consumption through optimization and efficiency projects
- Increase on-site generation of renewable power
- Procure off-site renewable power, including through renewable energy credits (RECs) and power purchase agreements (PPAs)
Energy use is a significant operating expense for HP and the main driver of our climate impact from operations. Our operations consumed 758,898 MWh in 2018, 6% less than in 2017. Global electricity use decreased by 8% compared to 2017, due to the implementation of energy conservation projects and real estate consolidation. Energy intensity equalled 13.0 MWh per $ million of net revenue in 2018, 16% less than in 2017.
During 2018, our main tactics to reduce energy use included a multi-site boiler optimization project, chiller optimization, retro-commissioning, conversion to LED lighting, and lighting control upgrades. Our energy team is collaborating with site operation teams that are replacing end-of-life equipment, to confirm that new high efficiency equipment is being installed. All new construction will comply with the HP Green and Smart Construction Playbook and the LEED v4 Gold Standard. In 2018, we implemented 29 projects at 12 locations, projected to save 8,500 MWh annually.
By shifting toward renewable, carbon-neutral energy, we can reduce GHG emissions from operations.In 2018, we procured and generated 275,944 MWh of renewable electricity globally, including four new onsite solar PPAs. Renewables accounted for 47% of our global electricity consumption. This decrease from 50% achieved in 2017 was due to re-baselining and real estate reduction at sites that used 100% renewable electricity. Sources of renewable electricity in 2018 included RECs and IRECs (77.1%), direct purchases (21.7%), and renewable energy generated on-site and on-site PPAs (1.2%). Through these purchases, we once again achieved our objective to use 100% renewable electricity in the United States and helped to advance the global market for renewables.
Business travel, commuting and auto fleet
To reduce emissions, we provide low-impact travel choices for our employees through collaboration with our travel providers, planning tools, and initiatives such as the Zipcar vehicle share program at our headquarters in Palo Alto, California, United States.
In 2018, employee business travel generated 70,000 tonnes of CO2e emissions, 2% more than in 2017. Commuting generated 200,000 tonnes of CO2e emissions, flat from the prior year. Our company fleet accounted for 32,200 tonnes of CO2e emissions, an increase of 2% compared to 2017.
Additionally, we were one of 10 founding members of EV100, a new Climate Group initiative to accelerate technological development of electric vehicles (EVs) worldwide. In support of this effort, we have committed to install EV infrastructure at all feasible sites worldwide by 2040.
