Huawei has built sustainability into its product development processes. We control the use of hazardous substances, and explore how to design more energy-efficient products. To adapt to future network technologies and evolving architecture, we have also created innovative power-saving solutions that reduce power consumption and carbon emissions. In addition, we provide first-class energy-efficient products and promote green ICT solutions to help conserve energy and reduce emissions in various industries.
Huawei has integrated the concepts of circular economy into its design for environment approach. We take environmental impact into account at every stage of product lifecycles, from raw material selection, processing, to use and disposal. We are working to minimize the impact we have on the environment.
We follow ISO14040 and ISO14044 to conduct lifecycle assessments and quantify the environmental impact of our products. LCA not only helps quantify the environmental impact of different products, but also informs us of how we can improve product design to make them more environmentally friendly, including improvements in raw material selection, manufacturing processes, energy use, packaging, transportation, and recycling.
To make its products' environmental information more transparent, Huawei created a Product Environmental Information platform and first rolled it out to its consumer domain. On this platform, we release environmental information reports for our various types of smartphones and tablets, so that consumers can find information regarding the environmental impacts of their products during their lifecycles.

Starting in 2013, Huawei has used bioplastics extensively in its mobile phones. Bioplastics are much more eco-friendly than traditional plastics because they are made from plant extracts rather than petroleum – a non-renewable resource. They can help greatly reduce environmental pollution and damage, and protect non-renewable resources.
In 2018, Huawei expanded its use of bioplastics to more products, including the P20, P20 Pro, Mate RS, Mate 20, Mate 20 Pro, and Mate 20 RS, as well as the base of Huawei Watch GT. More than 30% of the bioplastics are extracted from castor oil, leading to a 62.6% reduction in CO2 emissions. In 2018, Huawei's use of bioplastics helped reduce about 612 tons of CO2 emissions.
Huawei Device increasingly uses FSC certified packaging for our products to minimize the impact that our product packaging has on the environment and to protect forests. FSC is a supply chain management certification that ensures the materials for our packaging come from well-managed sustainable forests. This marks a huge step forward for protecting biodiversity. In 2018, the packaging for many of our products was FSC certified, including the P20, P20 Pro, Mate RS, Mate 20 Pro, and Mate 20.
In 2018, our lightweight packaging design also began to see results. Better design for retail packaging has helped improve resource utilization, with most phone packaging now about 20% lighter than previous designs. This equates to an annual reduction in CO2 emissions of about 5,813 tons.
We have also adopted lightweight designs for our logistics packaging to reduce carbon emissions during transportation. In early 2018, we launched a pilot program to reuse shipping cartons for product delivery. In 2019, this program will be rolled out for all shipments and is expected to reduce carbon emissions by 1,094 tons each year. At the same time, we have improved the materials used in our cartons. We have adopted a lightweight design while ensuring all packaging and assembly requirements are still met. Cartons are now 10% lighter, which is expected to reduce CO2 emissions by 994 tons each year.
Since 2008, Huawei has started using aircraft pallets, which are 50% lighter than plywood pallets. In 2018, the transported weight was reduced by 3,098 tons, equivalent to a CO2 emissions reduction of 808 tons.
Huawei owes its leading end-to-end 5G capabilities to its technological innovations in various domains like Massive MIMO, simplified sites, 5G microwave, and 5G chipsets. Huawei's 5G solution helps carriers deploy simplified 5G networks with superior performance. Specifically, this solution helps simplify network architecture, and greatly slash TCO, including buildout and operational costs, while ensuring the rapid deployment of large-scale, high-performance 5G networks.
We have also used high-integration chips, high-efficiency power amplifiers, and 5G-enabled power shutdown to save energy, cutting the power consumption of 5G equipment by 15%. In addition, Huawei has worked with carriers to develop 5G energy efficiency assessment standards, improve the methodology for defining and assessing 5G energy efficiency indicators, and drive continuous improvement of 5G energy efficiency.
1. Continuous Process Improvement and System-level Power Saving Solution
Huawei uses the Kirin 980 chip, which is manufactured using 7nm processors, in its multiple products, beginning with the Mate 20 series. This helps greatly improve performance and energy efficiency, and achieve optimal energy efficiency while providing excellent performance.
The Kirin CPU has an energy efficiency architecture consisting of four ultra-large cores and four small cores. This grants the CPU the flexibility to allocate the optimal amount of resources to heavy, medium, and light tasks, greatly reducing power consumption for the System on a Chip (SoC) in all scenarios.
A proper mechanism for allocating resources to different applications is a key factor that affects power consumption in mobile phones. Huawei's EMUI system can allocate resources in a way that optimizes energy efficiency and enhances battery life based on behavior prediction and component capabilities.
The battery life of the Huawei Mate series and P series is 30% longer than that of their predecessors. A total of 40 million users will save 114,000 kWh of electricity per day.
2. Using Innovative Technologies for Higher Performance and Lower Power Consumption
GPU Turbo, a revolutionary graphics processing acceleration technology, overcame the processing bottlenecks between Huawei's EMUI operating system and smartphone GPUs/CPUs. It makes graphics processing much faster and enables the SoC to use less energy, achieving an optimal balance between performance and power consumption.
As a new Android application compiler, Huawei Ark compiler can significantly improve the operating speed of mobile phones, make system operations smoother, and reduce the system overheads required when performing the same tasks.
Hazardous substances include any substances of which the use must be prohibited, restricted, reduced, or reported according to the law or customer requirements. These substances are detrimental to human health or the environment. To handle such substances, Huawei has established a management system in line with IECQ QC 080000 standards. In reference to global environmental laws and regulations as well as industry standards, we have developed regulations for managing controlled substances in consideration of the realities of our products. By doing so, we seek to protect human safety while reducing environmental impact throughout our products' entire lifecycle. These regulations apply to all restricted, reported, and to-be-restricted substances, guide the selection of materials at the product design stage, and set out requirements for suppliers and partners.
On December 26, 2018, Huawei Device was among the first to be awarded the new IECQ QC 080000: 2017 Certificate. The certification attests that the quality management system is more systematic, standardized, transparent, and complete regarding green products and the control of hazardous substances throughout our processes. It also lays a solid foundation to help us enhance compliance and build a sustainable, green device industry.
