Huawei is committed to ensuring its business is environmentally friendly, which is reflected by our low-carbon campus management. We have adopted initiatives to reduce our energy consumption and CO₂ emissions, such as implementing an energy management system, making managerial and technological improvements, and using clean energy. These efforts are helping us minimize the environmental impact of our business operations.
Energy and Resource Consumption Statistics of Huawei's China Region Operations from 2014 to 2018
Notes: In 2018, our consumption of natural gas, electricity, steam, and water grew as many new campuses and facilities in China became operational during the second half of 2017 and throughout 2018. These campuses and facilities include our Wuhan Research Center, Xi Liu Bei Po Cun in Dongguan, buildings E2B and E2C in Zone D of the Southern Factory in Dongguan, Zone A in the Nanjing Research Center, and Zone K at Shenzhen headquarters.
Most of the water we consume in our operations is used for landscaping, canteens, and air-conditioning systems. To reduce water usage, we have rolled out clean production technologies and adopted a variety of measures such as collecting rainwater, recycling cooling water, and buying reclaimed water for cleaning and landscape maintenance on campuses.
In 2018, we used 10.41 million m3 of water, up 28% year-on-year. This increase was largely attributable to our business growth, larger construction sites, and bigger landscaping areas.
2018 GHG Emissions
In 2018, the GHG emissions of our China Region operations totaled 2,083,666 tons, an increase of approximately 11% from 2017. This increase can be attributed to three key factors. First, our business grew significantly, with our annual revenue increasing to US$105.19 billion. Second, we built several new campuses. Third, we upgraded our office facilities.
Scope 3 GHG emissions include but are not limited to emissions from employee travel and commutes as well as emissions from suppliers' raw material production, transport of raw materials and products, product use, and product outsourcing. In 2018, Huawei calculated the GHG emissions from employee travel and commutes only.
In 2018, our CO₂ emissions per million RMB of sales revenue were 2.89 tons. This represented a 24.5% decrease compared to the base year (2012).
In 2018, we took a variety of initiatives to manage energy: identifying energy-saving opportunities and reinforcing the management of energy consumption by running the energy management system; setting measurable energy consumption targets at the company, regional, system, and equipment levels; and developing actionable energy-saving plans in line with the energy management strategy and energy consumption targets.
During a third-party annual audit, which examined how our Shenzhen campus managed energy, the auditor checked eight technological improvement projects (e.g., upgrading the electromechanical components of water chilling units) and two managerial improvement projects (e.g., reasonably adjusting air-conditioner temperatures) that Huawei had implemented. Improvement projects that were completed by September 2018 on our Shenzhen campus produced positive results, saving 1.72 million kWh of electricity. In November, Huawei passed the third-party annual audit based on ISO 50001 Energy Management Standards.
Executing a Green Logistics Service Strategy to Build a Sustainable Office Environment
In 2018, we referred to industry best practices and encouraged our campus management suppliers to manage energy more efficiently. This included setting procedures and control parameters for any common facilities that have a major impact on energy consumption, such as cooling facilities, electricity transformation and distribution systems, laboratories, and lighting systems. We also identified other variables that noticeably affect energy efficiency, such as temperature changes and staff capacity. We set and analyzed the parameters of the energy management system to ensure controls were effective. In 2018, we implemented more than 150 energy-saving programs on our campuses in China, saving over 50 million kWh of electricity.
Procuring Clean Energy for Green Campuses
In 2018, Huawei continued with our clean energy program. We actively worked with electricity suppliers and engaged with gas power plants that have clean energy capacity, which provided us with gas power to run our campuses. In 2018, we used about 932 million kWh of electricity from clean energy sources, representing an emissions reduction of about 450,000 tons.
We also estimated campus demand for electricity in 2019 and urged our electricity suppliers to negotiate with multiple gas power plants. We managed to purchase 1.19 billion kWh of gas power, which is expected to reduce carbon emissions by more than 560,000 tons.
Using Shuttle Buses Powered by New Energy
In 2018, we brought in over 800 new-energy shuttle vehicles for use on our campuses in China, replacing diesel buses. This is expected to reduce annual CO₂ emissions by about 32,000 tons.
Building More PV Plants on Our Campuses
We use clean and renewable energy to build green campuses that boast low carbon emissions. Our Southern Factory in Dongguan, Hangzhou Research Center, and Nanjing Research Center finished constructing their smart PV plants and connected these plants to the grid in June 2012, March 2015, and December 2017, respectively. These PV plants have a combined capacity of 19.35 MW, and generated over 16 million kWh of electricity in 2018. This is equivalent to a reduction in CO₂ emissions of more than 13,000 tons.
