Li Cheng (Lu Su), chief technology officer of Alibaba, judged that the orderly promotion of peak carbon dioxide emissions and carbon neutrality will bring about systematic changes in technology, which is likely to lead to new technological innovation and cooperation. At present, Ali has at least seen the "three rings" from the perspective of technological innovation: the development of enterprises to achieve emission reduction is the "inner ring"; Help platform enterprises and industries to decarbonize into "central"; Advocating low-carbon consumption and environmental protection is an "outer ring" with a wider radiation range.
When a large data center becomes a general computing brain, how to decarbonize computing technology and use technology to solve the problems brought about by technological development has become the focus of global attention.
With the growing scale of Internet companies, the energy consumption and emissions of data centers are also increasing year by year. According to the report, in the past few years, Alibaba Cloud has started to build relevant infrastructure, use clean energy and promote low-carbon production. In 2020, Alibaba Cloud's self-built base-based data center traded 4 1 100 million kwh of clean energy, up by 266% year-on-year, reducing carbon dioxide emissions by 300,000 tons, up by 1.27% year-on-year.
It is said that Alibaba Cloud Hangzhou Data Center has the largest immersed liquid-cooled server cluster in the world. Its servers are immersed in special cooling liquid, and the PUE (power utilization efficiency) is close to the theoretical limit value 1.0, which can save 70 million kWh of electricity every year. The saved electricity can be used continuously for all street lamps around the West Lake for 8 years. Guangdong Heyuan Data Center, which uses deep lake water for refrigeration, will use 100% green and clean energy in 2022, and will become the first large-scale data center in Ali to achieve carbon neutrality.
The report also gives a low-carbon equation. If all domestic servers adopt liquid cooling technology, the electricity saved in one year is close to the Three Gorges; If the "urban brain" fully participates in urban congestion control, the traffic congestion rate can be reduced by more than 15%; If the intelligent packaging algorithm of express delivery is popularized, most of the 50 billion parcels in the country can be slimmed down; If the idle items in the home can be fully circulated, a mobile recycling factory will reduce the carbon footprint of users.
In 2020, Alibaba began to increase investment in digital infrastructure and open plug-and-play digital capabilities to the whole society. On the one hand, it helps small and medium-sized enterprises to reduce costs and improve efficiency, and at the same time, it also enhances the "green value" of many enterprises.
It is mentioned in the report that the "steel brain" of Panzhihua Iron and Steel Co., Ltd., which was developed with the assistance of Alibaba Cloud, currently saves 1 .28kg of iron per ton of steel, and saves the steelmaking cost 1.7 million yuan per year; Alibaba Cloud assists waste incineration power generation enterprises to improve combustion stability by 23%; Nailing paperless office reduces carbon emissions 1 1 ten thousand tons, which is equivalent to curing 6,300 square kilometers of desert. ...
According to the report, Alibaba Cloud, Dharma Institute, Nail and other technical forces are constantly condensing innovation and promoting a multi-dimensional and full-coverage low-carbon development system.
The report shows that Alibaba is actively deploying green consumption: Alibaba is forming a green consumption chain through rookie, idle fish, hungry and Yintai, and building a "life cycle green consumption scene".
The data shows that since 20 14 years, the number of packages using electronic face sheets by novices has exceeded10 billion, saving 400 billion pieces of paper and 20 billion yuan in cost. Green recycling bins cover 3 15 cities, and more than 10 billion cartons have been recycled. Hungry? Send 400 million orders without tableware, and reduce carbon emissions by 6,400 tons.
20 17 Up to now, Idle Fish has recovered more than 50,000 tons of old clothes, 23.7 million old books, 3.66 million mobile phones and 6.5438+0.45 million household appliances. In 2020 alone, idle fish users will have 654.38 billion idle items on the shelves. In 2020, Yintai Miaojie recycled more than 20,000 empty bottles through paperless cashier and electronic invoice receipt, saving 1.600 tons of paper.
It is reported that in February this year, Alibaba has issued a 20-year "green bond" of US$ 654.38+0 billion, and the funds raised are specially used in the fields including green building, energy efficiency, COVID-19 crisis response, renewable energy, circular economy, design, etc. It has also become the first enterprise in the Asian Internet industry to issue green bonds.
"Alibaba will launch a roadmap for carbon-neutral technology development as soon as possible. To achieve carbon neutrality, we must take the technical route. This is not a single struggle at any level, it requires the joint efforts of the whole society, "Li Cheng said.
