Green Operation

Minimizing the environmental footprint of our operations is a long-term initiative at Huawei and we use a number of approaches to reduce our energy consumption and CO2 emissions. These include implementing an ISO 50001-based energy management system, launching energy conservation programs, making managerial and technological improvements, and utilizing clean and renewable energy. Our goal is to help fight climate change. Through operational and technological measures, we saved 33.57 million kWh of electricity in 2017. We also built solar power stations on our campuses, generating 17 million kWh of electricity. These measures combined to reduce our CO2 emissions by more than 45,000 tons.

Energy Consumption Statistics of Huawei's China Regional Office from 2013 to 2017:

Building an ISO 50001-based Energy Management System

Huawei has established an energy management system in accordance with the ISO 50001 standard and relevant laws and regulations. In 2017, our Shenzhen headquarters obtained an ISO 50001-based third-party certification. We continuously optimized our energy management system, making it more effective and energy efficient, with lower energy consumption. This was achieved through multiple initiatives, including routine monitoring of energy conservation, energy auditing, internal auditing, and upgrading to energy-efficient technologies. When our energy management system was being audited by a third party, we adopted 28 improvement measures, completed energy upgrading projects that saved 2.07 million kWh of electricity, and leveraged management approaches that saved 2.5 million kWh of electricity, equivalent to a carbon emissions reduction of over 3,965 tons.

Maximizing Energy Conservation with Big Data Analytics

We have introduced third-party experts to assess energy efficiency on our Shenzhen and Dongguan campuses. In this pilot project, we identified 36 areas for improvement in energy-saving. In 2017, we improved on 22 areas. Specifically, we upgraded the chiller plants and cooling tower fans with variable-frequency drives in the air conditioning system, and analyzed the big data from the system to develop a mathematical model. By running virtual tests of energy savings, we were able to configure the building automation system for automatic maximum savings based on the conditions outside. Over the course of a year, this system saved 4.6 million kWh of energy, equivalent to a reduction in carbon emissions of 4008tons.

Building More PV Plants on Our Campuses

We use clean and renewable energy to build environmentally friendly campuses with low carbon emissions. Our Hangzhou Research Center and Southern Factory in Dongguan completed construction of their smart PV plants in June 2012 and March 2015 respectively and connected them to the grid. The two PV plants together have a capacity of 19.3 MW, and generate 17 million kWh of electricity each year, equivalent to a reduction in CO2 emissions of over 15,000 tons. In 2017, Huawei continued to increase its investment in PV plants. Currently, the PV plant in Beijing Research Center is under construction. The project is planned to have a capacity of 771.3 kW, which will meet the majority of the energy needs of the research center.

To achieve Huawei's 2020 carbon emissions target, we launched a series of projects and activities aimed to save energy and reduce emissions in 2017. In addition to the initiatives mentioned above, we also renovated air-conditioning systems, upgraded light controls, and reduced energy consumption of our manufacturing and lab equipment. These measures created additional reductions in CO2 emissions of 22,000 tons.

Procuring Green Energy for Green Campuses

As our business continues to grow, we have seen a significant increase in the electricity consumption of our labs and data centers. To reduce operating expenses and improve the utilization of clean energy, we engaged in in-depth discussions with our electricity suppliers, and worked to encourage them to sign an agreement with a gas power plant that has installed clean energy capacity. The supplier ended up getting 932 million kWh of electricity from clean energy sources, all of which will be supplied to Huawei in 2018. Huawei obtained a statement on reducing GHG emissions from a third party certification organization, saying our carbon emissions reduction is estimated to reach 450,000 tons.

2017 GHG Emissions

In 2017, the GHG emissions of our China Region operations totaled 1,876,496 tons, an increase of approximately 18.4% from 2016.

This increase is attributable to two factors. First, our business grew significantly, with annual revenue increasing to US$92.5 billion, up 23% from 2016. Second, we expanded our building facilities.

Huawei's carbon emissions target for 2020:

Reduce carbon emissions per unit of sales revenue by 30% compared to the base year (2012) by 2020.

In 2017, our CO2 emissions per million RMB of sales revenue were 3.11 tons, 9.3% lower compared to the base year.

Sustainable Design to Build Energy-efficient and Green Campuses

Huawei builds sustainability into campus design at the very outset, aiming to build energy-efficient and green campuses. We used dynamic thermal simulations to optimize the thermal performance of walls, doors, windows, roofs, and building foundations, as well as the design and control of air conditioning systems. We have made full use of passive design, such as natural ventilation and natural lighting. With equipment performance and cost into consideration, we have also deployed new energy-saving equipment and designs, including low radiation glass, double-skin facade, fresh air heat recovery units, chillers with variable-frequency drives, on-demand air supply and air conditioner box control, as well as occupancy sensing lighting systems and equipment.

We also deployed metering and monitoring instruments to collect data. Specifically, we have installed cold and hot water heat meters, as well as sensors to collect data about electricity, temperature, humidity, flow, and pressure. These sensors have enabled us to monitor the running data of air conditioners, lighting systems, and chiller plants in real time, and frequently collect and archive important parameters. We also track important energy efficiency indicators, such as the coefficient of performance (COP) of chiller plants, cold and hot water consumption per unit of building area, and power usage effectiveness (PUE) of data centers.
