Ningbo is rolling out its road map for peaking carbon emissions by 2030, aiming to achieve low-carbon transformation in a diversified way.
According to this year's government work report, China will reduce energy consumption and carbon dioxide emissions per unit of GDP by 13.5 and 18 percent, respectively, during the 14th Five-Year Plan period (2021-25).
To fulfill the ambitious target, Ningbo has taken multiple measures to lower carbon emissions, with a focus on optimizing industrial and energy structures.
Photovoltaic Project
Achieves Win-win Result
Official statistics show that photovoltaic power has become the second largest source of electricity in Zhejiang after thermal power. More than one seventh of the province's power needs are met by solar energy. In terms of installed photovoltaic capacity, Ningbo is the leader in Zhejiang.
In Xiepu, Zhenhai, a solar farm built over the water surface of Lanshan Reservoir has achieved a win-win result.
The 1.45-billion-yuan solar farm is capable of generating 209 million kilowatt-hours of electricity per year, equivalent to the annual consumption of 100,000 households in Zhenhai.
The power generated by photovoltaic modules placed over the water is usually higher than those placed on rooftops and grounds because of the cooling effect of water.
Annually, the solar farm can reduce the consumption of standard coal by about 60,000 metric tons, carbon dioxide emissions by 151,300 tons, sulfur dioxide emissions by 5,000 tons, and nitrogen oxides emissions by 532 tons.
Besides, a photovoltaic project erected over tidal flats in the western part of Gaotang island in Xiangshan was put into operation recently.
The project, the largest of its kind in the nation, is expected to generate an average of 340 million kilowatt-hours of electricity annually, thus reducing carbon dioxide emissions by 270,000 metric tons per year and aiding Xiangshan's goal of being powered solely by clean energies by 2025.
This model makes it possible to generate photovoltaic power and breed aquatic products at the same time and same place.
Push Ahead with
Hydrogen Energy Plans
Hydrogen, known as "the ultimate energy in the 21st century", is considered as the most promising clean energy. Ningbo is gearing up for the development of hydrogen fuel cell energy, another green energy solution for vehicles, and has released specific plans for the industry.
Ningbo's first hydrogen refueling station, which will be opened to fuel hydrogen fuel cell vehicles, has recently completed construction in the city's Zhenhai district.
The station, built by Sinopec Zhenhai Refining & Chemical, covers a total area of 19 mu (1.26 hectares), with a daily capacity of providing 500 kilograms of hydrogen.
As one of the seven national petrochemical bases, Ningbo is now ready to supply 72,300 metric tons of hydrogen byproducts per year, which can be feed up about 360,000 hydrogen fuel cell passenger cars.
The city was ranked ninth among China's top 30 cities in hydrogen competitiveness in 2020.
Ningbo aims at lifting the output value of the hydrogen industry in the city to above 40 billion yuan ($6.15 billion) by 2025, according to a drafted local government development plan.
The figure is targeted to exceed 150 billion yuan by 2035.
Set to be the National
Leader in Garbage Classification
Recently, Ningbo has been ranked among the top three cities in China in promoting garbage classification for the first half of this year. A total of 397,400 metric tons of recyclables were collected in the city from January to July, resulting in a decrease of 79,000 tons of carbon dioxide emissions.
To date, Ningbo has launched smart garbage recycling machines in 12 sites across the city. Residents are required to dispose of their garbage in a classified manner after swiping cards, scanning their faces, or inputting codes to operate the machines.
The machines are able to automatically break disposed garbage bags and weigh the content. They are also equipped with facial recognition and AI technologies to identify users attempt to break the rules.
In the first half of this year, 259 Ningbo residential communities were designated provincial models for garbage classification, 59 more than the target pre-set by the city.
The city's 11 major express parcel distribution centers have all adopted recyclable plastic bags, while 81 star-rated hotels have banned the use of disposable products.
Over the six-month period, a total of 1,892 cases related to municipal garbage classification law violations were handled in Ningbo, with fines exceeding 180,000 yuan ($27,692).
