Huawei hosted its Day0 Forum "Lighting up the Future" as part of their lead up 
to MWC22 Barcelona. Huawei Carrier's Chief Marketing Officer Dr. Philip Song 
delivered a keynote speech titled "Five Misconceptions of Green Development" at 
the forum. He said, "Green development is a buzzword. Just like from Newton's 
classical mechanics to Einstein's theory of relativity, its development is 
going to be marked by a spiraling path between misconceptions and truths. We 
need to move past these five misconceptions as soon as possible to accelerate 
the green development of the ICT industry."

Misconception 1: ICT industry contributes to increased carbon emission. 
According to the GeSI's SMARTer2030 report, the ICT industry is only expected 
to account for 1.97% of global carbon emissions by 2030. More importantly 
though, other industries are expected to reduce their own carbon emissions 20% 
by applying ICT technologies, a total amount 10 times the carbon emissions of 
the ICT industry itself. These secondary savings are called carbon handprint. 
The size of this carbon handprint has made ICT infrastructure increasingly 
important in many national strategies. Huawei itself predicts that 1 YB of 
global data will be stored on the cloud by 2030. This means that 150 million 
tons of carbon emissions can be saved each year if current infrastructure is 
equipped with greener, all-optical transmission technologies. These savings 
would be equivalent to planting 200 million trees – an amount that would cover 
the entirety of Europe in forest.

Misconception 2: There is over-focusing on supply chain emissions, which are 
regarded as the largest cause of carbon emissions for network equipment. As Dr. 
Song described in his presentation, if you look at the entire life cycle of 
network equipment, only 2% of its carbon emissions are generated during 
manufacturing, while 80-95% are generated during usage. Dr. Song therefore 
proposed that the key to reducing ICT industry carbon emissions will be 
adopting innovative technologies to improve energy efficiency.

Misconception 3: Green development is only about green energy. While the 
development of solar and wind power are important to green development in the 
ICT industry, huge gains can be achieved by systematically improving the energy 
efficiency of telecom networks. To this end, Huawei released a three-layer 
green solution at this summit to systematically improve network energy 
efficiency through "Green Site, Green Network, and Green Operation", helping 
carriers achieve "More Bits, Less Watts".

Misconception 4: Network energy efficiency is equal to the sum of energy 
efficiencies of its telecom equipment. The energy efficiency evaluation of a 
single equipment box is not enough to carry out comprehensive, scenario-based 
planning and construction decisions. Huawei recommended establishing a unified, 
standardized indicator system (NCI) to accurately evaluate and formulate 
energy-saving policies for entire networks by measuring the energy efficiency 
indicators of main communications equipment, site auxiliary equipment, 
transport networks, and data centers.

Misconception 5: Energy saving should not impact any network performance 
indicator. The truth is, there is trade-off between energy saving features and 
some network indicators. However, energy saving features can be adopted at the 
expense of peak rates and some other indicators, but without impacting actual 
user experience. In Germany, an intelligent shutdown solution has been deployed 
in shopping malls at midnight. Although it slightly reduces peak rates, it 
reduces site energy consumption by 10% without affecting user experience.

During his closing remarks, Dr. Song delivered five suggestions for green 
development in the ICT industry: "First, we should vigorously develop the ICT 
industry to enable green development in other industries. Second, we must pay 
more attention to carbon emissions of ICT infrastructure during usage rather 
than just during manufacturing. Third, the systematic solution of "Green Site, 
Green Network, and Green Operation" will help carriers continuously improve 
network capacity and reduce power consumption per bit, achieving "More Bits, 
Less Watts". Fourth, we must define a unified energy efficiency indicator 
system to identify the main problems of energy consumption. Fifth, watts are 
decided by user experience."

MWC22 Barcelona will run from February 28 to March 3 in Barcelona, Spain. 
Huawei will showcase its products and solutions at stand 1H50 in Fira Gran Via 
Hall 1. Together with global operators, industry professionals, and opinion 
leaders, we will dive into topics such as industry trends, GUIDE to the Future, 
and green development to envision the future of digital networks. For more
