During the "14th Five-Year Plan" period, our country's digital economy has entered a new stage of development focusing on the integration of data and reality and industrial interconnection. What can technology companies do on the road of green and low-carbon high-quality development?

On August 23, the 2022 China Industrial Internet (Jiangmen) Summit Carbon Neutral Open Patent Technology and Application Sub-Forum gave the answer. At the meeting, 10 companies including Tencent, Microsoft China, Alibaba, Baidu, JD.com, Kuaishou, Ant Group, Meituan, Vanke, and Wasion Information jointly announced that they will form a carbon neutrality professional committee and an open technology alliance. For the first time, the member companies of the Carbon Neutralization Committee take openness and sharing as the core concept, disclose the patented technologies related to energy conservation and carbon reduction, and open them to the member units. In the first round, 189 patented technologies will be shared free of charge.

Enterprises complying with the national "double carbon" target actively promote the process of carbon neutrality

"To achieve carbon peaking and carbon neutrality is a tough battle and a big test, which requires extremely arduous efforts. Strong technological support and advanced technology transformation and application are essential key forces, and more importantly, it depends on the joint efforts of experts, scholars and enterprises." Zhou Peishan, deputy mayor of Jiangmen, Guangdong province, said in her speech.

The Carbon Neutrality Professional Committee, led by Tencent, jointly established a public welfare patent pool with domestic and foreign enterprises of the United Nations, which will open its technology patents to members and license them free of charge. They cannot be used for other commercial purposes.

The first round of disclosed patented technologies involve computing optimization, storage saving, network resource saving, computer room data center, equipment energy consumption control, transportation energy saving and emission reduction, building energy saving and other aspects, and realize energy saving and efficiency improvement solutions through various software and hardware technical means. For example, the patent of image data resource compression method solves the technical problem that image resource compression takes up a large amount of memory and causes a large bandwidth burden during transmission. It is a storage saving scheme under the energy saving label of carbon neutral cloud infrastructure.

"This year, flooding and drought in the south in the north of China all kinds of extreme weather, and fire disaster makes us realize the impact of climate change, climate change and to cope with the low carbon transition across the economy has reached a more imminent stage." Xu Hao, vice president of Sustainable Social Value at Tencent and head of Carbon Neutral Laboratory, said, "On the industrial side, we hope to make full use of Tencent's capabilities in the digital field to help traditional industries and industries with high carbon emission intensity, such as steel, cement, power and chemical industries, to achieve low-carbon transformation. "Digital transformation can significantly improve the productivity of these companies, which naturally leads to increased energy efficiency and greenhouse gas reduction levels."

Technology helps carbon neutrality and digital technologies boost efficiency in transition

Digital technologies could reduce global carbon emissions by 20 percent over the next decade by empowering other industries, according to the Global Association for the Advancement of Electronic Sustainability. According to the "Global Communication Technology Enabling Emissions Reduction Report" co-authored by the Mobile Systems Association and the Carbon Trust, digital technologies reduced global greenhouse gas emissions by 2.135 billion tons in 2018, almost 10 times the mobile Internet industry's own carbon footprint.

At the meeting, Zhai Yongping, senior consultant of Tencent's Strategic Development Department, hosted a roundtable forum, where experts and practitioners in related industries expressed their views on how digital technology can help the industry achieve low carbon transformation and carbon neutrality, and expressed their views and prospects for the future.

Liang Jiaqi, head of Tencent data center double carbon, talked about from the perspective of data center, Tencent strives to optimize and improve the PUE of data center, and continuously improve the green level of data center by using the latest generation of TBlock technology, AI, micro grid and so on. In terms of carbon emission reduction, CCUS technology, virtual electric field technology, new refrigeration coatings, efficient refrigeration technology, fuel cells, emerging photovoltaic technology, etc., are adopted to improve the ability of sustainable development in an all-round way. It is hoped that Tencent can participate in the industry empowerment and make the industry do better in carbon neutrality.

Yang Xing, Director of Investment Development and head of Power Trading and Carbon Neutrality at Kuaishou, said, "Kuaishou is an enabling content industry company, focusing on green operations and taking special actions. Last year, the energy consumption of air conditioners in office parks decreased by more than 50%. In the latest issue of the corporate social responsibility report clearly proposed to achieve 100% green power and clean energy use in self-built data centers by 2030."

Dai Xuan, head of Baidu intelligent Cloud Internet of Things platform, shared Baidu's efforts in improving the PUE of IDC, intelligent lighting of office buildings, intelligent heating and heating, as well as digital and refined control of the energy expenditure in the production link of the factory's intelligent manufacturing field, in order to achieve the effect of energy saving and emission reduction and other specific measures. Baidu opened a number of green and low-carbon patents this time, mainly related to energy saving and emission reduction technology of data centers and servers, to help the whole society achieve energy transformation, energy saving and emission reduction through green computing power, and accelerate the development of "green AI".

Wang Weiwei, Chairman of Vanke's Honorary Chairman's Office, said, "Twenty years ago, Vanke was one of the first companies in China to participate in promoting industrial upgrading and green buildings. Today, Vanke is strategically positioned as an urban and rural construction and life service provider, and is consolidating residential development. On the basis of the inherent advantages of property services, the business has extended to business, long-term rental apartments, logistics and warehousing, ice and snow vacations, education, etc. In the scenarios of thousands of households and enterprise customers served by Vanke, digital technologies such as the Internet are greatly needed to realize the interconnection and improvement of quality and efficiency in carbon neutral actions. At the same time, the Vanke Foundation has also participated in and supported Chinese companies in responding to climate action all year round, and has represented Chinese companies in the climate conference (cop) for many consecutive years. Recently, we are discussing how to better promote more companies to participate in carbon neutrality through blockchain technology - Tencent Zhi Xin Chain with Huawei, LONGi, Geely and other companies."
