Huawei has established an energy management system in accordance with the ISO 50001 standard and applicable laws and regulations. We have made our energy management system more effective through routine energy monitoring, energy audits, internal reviews, and technology upgrades. This allowed us to minimize energy consumption, make the best use of energy, and meet our energy management principles and goals.
Our energy management system, with a full clarification of the energy management responsibilities of different departments, provides the necessary framework for ensuring the sustainability of our energy conservation efforts. Breaking down energy conservation goals into actionable tasks and defining responsibilities are vital for us to achieve our goals at different stages of development.
As a result of our business growth and building expansion, in 2016, our energy consumption (measured in standard coal equivalent) totaled 224,000 tons, an increase of 27.3% from 2015. That said, we decreased our energy consumption per unit of sales revenue by 20.2% compared to our benchmark year (2012). Our China region operations saved 45.7 MWh of electricity, equivalent to a CO2 emissions reduction of approximately 42,000 tons. We also utilize renewable energy. By the end of 2016, we had installed solar power stations with a total generating capacity of 19.3 MWh. They generated 17.07 MWh of electricity in 2016, equivalent to a CO2 emissions reduction of over 15,000 tons.
In the past year, we took the following initiatives to cut energy usage by our offices, laboratory equipment, and manufacturing facilities.
- Strengthening energy management: We regularly collected and analyzed energy statistics to better meet our energy targets. We also expanded energy management training, and improved awareness with internal promotional events.
- Improving electricity metering and management systems: We built and connected electricity management systems in our campuses to monitor and analyze real-time electricity usage in different locations and to effectively manage our energy consumption.
- Optimizing energy management in laboratories: In 2016, we cut laboratory energy usage by replacing legacy direct current power modules with more efficient equipment; deploying automatic switch-off tools; identifying and removing idle equipment; and enclosing the hot and cold air conduits within air conditioners. As a result, we saved 32.92 MWh of electricity.
- Promoting more efficient technologies: We continued to upgrade our lighting systems (e.g., installing more energy-efficient bulbs, LED bulbs, and lighting control systems) and air conditioners (e.g., centralizing refrigeration controls and improving maintenance procedures). In 2016, these measures helped us save 3.5 MWh of electricity.
- Optimizing our manufacturing: In 2016, we reduced energy usage by 3.86 MWh. This was achieved by reducing energy consumption (e.g., upgrading our air compressors and removing evaporative cooling pads; and adjusting the working hours of air conditioners), optimizing equipment (e.g., the operational usage of air conditioners, adjusting the time of temperature testing, retrofitting improved machinery, and electricity self-circulation during product aging procedures), and upgrading lighting systems (e.g., replacing metal-halide lamps and installing energy-efficient bulbs).
Increasing Energy Efficiency in R&D Labs
Some of our first R&D labs were scattered in different places, and their air conditioners and power systems were inefficient, with an average power usage effectiveness (PUE) as high as 2.5.
To increase energy efficiency and reduce carbon emissions, we built large centralized labs in the Chinese cities of Dongguan, Langfang, and Chengdu. Leading technologies and facilities – such as free cooling, separation of hot and cold air conduits, and efficient power supply cabinets – reduce lab PUE to below 1.5 and make the labs 40% more energy efficient. As a result, our labs are able to save 71 MWh of electricity every year, equivalent to a CO2 emissions reduction of over 65,000 tons.
Large centralized labs with higher energy efficiency
Greenhouse gas (GHG) management is an integral part of our operations. We have adopted the ISO14064 standard to identify GHG emissions, and have taken concrete steps to save energy and reduce emissions.
After quantifying and analyzing our GHG emissions, we set a goal of reducing the GHG emissions per unit of sales revenue by 30% by 2020 compared to 2012 (our designated benchmark year). At present, we are continuously monitoring and improving our GHG management performance. To decrease our carbon footprint, we have established energy management systems, rolled out energy conservation projects, and introduced clean energy sources.
