Green Operation

Huawei has proactively responded to climate change. While using ICT technologies to help society reduce energy consumption, we also strive to minimize the direct environmental impact of our operations. We have decreased our energy consumption and CO2 emissions through a range of measures. These include introducing energy management systems, replacing traditional energy with renewable energy, and adopting technological and managerial approaches to energy conservation.

Energy Management

Due to our continued business growth and expansion of construction areas, in 2015 our energy consumption (measured in standard coal) totaled 176,000 tons, an increase of 18.1% year-on-year. Energy conservation and emissions reductions have been the focus of our green initiatives in recent years. Through a variety of measures, in 2015 we managed to decrease our energy consumption per unit of sales revenue by 13.8% year-on-year. By adopting managerial and technological improvements, our China Region saved 44.3 million kWh of electricity, equivalent to a CO2 emissions reduction of approximately 40,000 tons.

Cleaning Air Conditioners’ Condensers with the Power on

In 2015, we installed cleaning devices for the condensers of 38 air-conditioning chillers in our HQ. These cleaning devices can be used to clean condensers with the power on. This feature decreases the temperature differences during heat transfer, and can thus boost heat transfer efficiency.

Empirical data reveals that every 1℃ decrease in condensing temperature translates into a 3% improvement in cooling efficiency, or an annual reduction of around 2 million kWh of electricity.

Green Buildings

In 2015, we began to pilot green building concepts in our Global Compliance and Testing Center (GCTC) at our Songshan Lake Campus in Guangdong, China. The new center has been designed and constructed in accordance with world-leading green standards, from site selection and energy and water conservation to material utilization.After conducting energy consumption analys i s and thermal simulation, we applied 13 leading energy-efficient technologies at the center (see the following table).The center is expected to reach the Gold level of the US Leadership in Energy and Environmental Design (LEED) and pass China’s Green Building (3-Star) certification.

The new center will consume much less water and electricity than our older buildings, and will be less costly to maintain.Every year, the building is expected to help us save 2,375,000 kWh of electricity, and avoid 1,415.5 tons of CO2 emissions.

Maximizing Resource Efficiency

In the face of accelerating socioeconomic progress and population growth, natural resources are being consumed faster than they are replenished. If this trend continues,sustainable development will be impossible. This resource dilemma is also a major challenge for enterprises: They have to use resources efficiently to maximize value, increase competitiveness, and reduce OPEX.

Water Resource Management

In recent years, water shortages have increased in severity for two reasons. First, water resources are in tremendous demand but they are not being used responsibly. Second,the accelerating pace of industrialization is leading to severe water pollution. For example, the chemical, printing, dyeing,paper, and electroplating sectors use a high volume of water and produce high emissions.

Huawei takes water conservation seriously and has launched water conservation initiatives to better manage our water consumption. By adjusting the proportion of water types and changing the way we use water, we have increased water utilization and reduced waste. For example, we have built facilities to recycle and reuse rainwater, wastewater,reclaimed water, cooling water, and condensates. We have also effectively managed and maintained water supply networks, water facilities, equipment, and appliances to prevent water leakage.

Most of the water we consume in our operations is used for landscaping, canteens, and air-conditioning systems. To reduce water consumption, we have promoted 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 2015, we used 7 million m3 of water, an increase of 1.5 million m3 year-on-year. This increase is largely attributable to our business growth, larger construction and landscaping areas, and use of reverse osmosis water purification systems on all our campuses across China.

Our effluent discharges come primarily from domestic sewage. Domestic sewage at all of our campuses is sent to municipal wastewater plants for treatment, and is monitored by third parties to ensure compliance with local and national standards.

Lowering the Landfill Rate of Waste

We obey e-waste laws and regulations in all countries in which we operate. By recycling and reusing as many waste products as possible, we have lowered the landfill rate of waste.

Bringing Together Scrapping Service Providers to Effectively Dispose of E-waste

In 2015, we selected leading scrapping service providers in line with our needs and local government requirements. Our close collaboration with these service providers resulted in more effective disposal of e-waste, reduced the rate of waste that went to landfills, and ultimately ensured the green processing of waste.

Managing Greenhouse Gases

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, in 2014 we set a goal of reducing the GHG emissions per unit of sales revenue by 10% in five years (compared to 2012). Since then,we have continuously monitored and improved our GHG management performance. To decrease our carbon footprint,we have established energy management systems, rolled out energy conservation projects, and introduced clean energy.

Note:

Scope 1 includes stationary combustion emissions, mobile combustion emissions, and fugitive emissions

Scope 2 includes indirect emissions from energy.

Reducing Carbon Emissions from Manufacturing

Green manufacturing is always at the forefront as we consider how to maximize energy efficiency and minimize our energy use and carbon footprint at the manufacturing stage. In 2015, we adopted a combination of approaches to save 9,639,800 kWh of electricity, equivalent to a CO2 emissions reduction of 9,011 tons. Approaches include increasing employees’ energy awareness, optimizing energy management, improving technologies, refining product packaging, redesigning logistics and transportation systems, and introducing clean energy.
