The highlight of the forum is here

"What is a carbon is neutralized"

"Carbon reduction" is changing lifestyle

Speaker: Wu Xi

Professor at the School of Energy of Suzhou University

The goal of my country's carbon peaks means that before 2030, the discharge of carbon dioxide no longer increased, and gradually fell. Carbon dioxide is a historical turning point for carbon dioxide emissions from the increase and rotation, marking the decoupling of carbon emissions and economic development.

Carbon neutralization refers to the total amount of greenhouse gas emissions generated directly or indirectly in enterprises, groups or individuals within a certain period of time. Through the form of trees and afforestation, energy conservation and emission reduction, the carbon dioxide emissions produced "".

At present, my country ’s carbon emissions are about 10 billion tons throughout the year. Carbon neutrality in 2060 means that my country will gradually reduce the cleanse of carbon discharge in 40 years and finally return to zero.

The relevant mechanism of reducing "carbon emissions" has begun to change our lives. For example, carbon and benefits explored in some provinces are one of the design system design. By using carbon coins, discounts and value -added services provided by enterprises, such as discounts of catering and entertainment, let the public feel the direct economic value brought by low -carbon in daily consumption, and enhance the public to practice low -carbon carbon. Autonomy.

"The Future of Carbon Coses: Carbon neutral from the world to China"

Energy structure optimization is the fundamental countermeasure of emission reduction

Speaker: Li Zheng

Deputy Director of Science and Technology Innovation Department of Suzhou Environmental Innovation Research Institute of Tsinghua University

Carbon neutralization and green finance collaborative innovation laboratory executive secretary general

China's energy endowment is more poverty -stricken oil, so energy consumption is currently mainly fossil energy, and oil and gas have a high degree of exterior dependence.

Li Zheng said that in the future, the total energy consumption of my country will grow further. While continuously strengthening energy conservation, the optimization of energy structure is the fundamental countermeasure of emission reduction, that is, fossil energy structures represented by coal, natural gas, oil, etc. Non -stone energy structure represented by photovoltaic and wind power.

At the same time, low -carbonization consumption is fundamentally reduced carbon emissions. At present, 55%of greenhouse gas comes from energy use, and 45%of greenhouse gas comes from our daily items, such as cars, clothing, food and other products.

For example, changing the way of travel in life can promote the carbon reduction of the transportation sector, and saving electricity can promote the carbon reduction of the power department. Therefore, low -carbonization of consumption is an important cause of low -carbon transformation in production, which is conducive to the understanding and support of the public.

"Carbon neutralization: Destruction and reshaping"

The low -carbon industry needs innovation from big to strong

Speaker: Zhang Junjie

Director of Kunshan Duke University Sustainable Investment Research Project

Zhang Junjie believes that local zero carbon is meaningless, and zero carbon worldwide is the truth. In 2021, among the top 10 global fan manufacturers, Chinese companies accounted for 6 seats; in 2020, China's photovoltaic components accounted for 67%of the global market.

Judging from the road of low -carbon transformation, China has caught up with this wave. China is a large country with a low -carbon industry, but many original technologies do not belong to us. To reshape the Chinese economy in zero -carbon constraints and make the low -carbon industry stronger from big, it is necessary to achieve innovation.

From the 1990s to the present, the number of applications for China has risen rapidly in the number of patent applications in 4 categories -environmental green innovation patents, energy conservation patents, alternative energy patents and transportation patents, and has surpassed Western countries in terms of quantity, bringing new energy and low -carbon industry costs The significant decline reflects the value of innovation.

"Carbon" "Carbon" Road to Find Ecological Landscape "

Ecological landscape disciplines should establish a quantitative evaluation system

Speaker: Zhang Yixin

Professor of Suzhou University Golden Mantis School of Architecture

Zhang Yixin said that the neutral carbon and neutralization of ecological landscape methods and sustainable paths are not just energy saving and emission reduction, increasing the ability to fix the carbon, but comprehensively evaluating and paying more attention to the ability of sustainable development in the region. This is a sustainable long -term benefit. Essence

Although biological diversity, ecosystem function, and ecological environment often do not participate in carbon neutrality in direct ways, their role is critical and indispensable.

For example, when the sewage treatment is performed on the dang, it directly affects the ecosystem function of the water body, improves water quality, optimize flow, etc. These can indirectly affect the use of carbon emissions and other ecological functions.

The research of carbon neutral ecological landscape methods and sustainable paths has guiding value in future planning and design. In the future, an effective quantitative evaluation system should be established to fully study the modular plant planting ratio, the advantages and disadvantages of spatial distribution, and the construction of related models.

"Carbon" Secret Trash "

Implementing garbage classification is good for low -carbon environmental protection

Speaker: He Sheng

Deputy Director of Suzhou Waste Classification Management Center

He Sheng explained that the garbage itself has resource attributes. Through the classification of garbage, the possibility of resource reuse is greater, which is more conducive to low -carbon environmental protection.

Such measures have been confirmed in related countries. For example, from 1990 to 2006, the emissions in the field of garbage management in Germany decreased from 38 million tons/year in 1990 to 18 million tons/year in 2006, with an average annual decrease of 56 million tons/year. At the stage, the German greenhouse gas emission reduction was 24%.

The "Fourteenth Five -Year Plan" urban domestic waste classification and treatment facility development plan proposes that by the end of 2025, the utilization rate of resource resourceization of urban domestic garbage will reach about 60%; by the end of 2025, urban domestic waste incineration treatment capacity will account for about 65%. Essence

According to statistics in 2020, at present, the number of domestic garbage clearance is 235 million tons/year, and Suzhou's domestic garbage clearance volume is 3.607 million tons/year. The resource and reduction of garbage will have a positive role in achieving Suzhou's "double carbon" targets of carbon peaks and carbon neutralization.

"Ideal Carbon City"

Build an ideal carbon city is the path to realize "zero carbon"

Speaker: Yang Jianxun

PhD in Nanjing University School of Environmental College

Yang Jianxun said that carbon dioxide is closely related to economic activities. From the perspective of the carbon dioxide emissions ratio of various sectors, the discharge ratio of industrial and electric sectors has reached 30%and 26%, respectively.

Considering the close connection between carbon emissions and economic development, how to achieve the "zero carbon" goal in the past 40 years is a challenging task

Yang Jianxun believes that the construction of ideal carbon cities is needed, and the low -carbon transformation of the industrial economy and social lifestyle continues to reduce the emissions of greenhouse gas, and finally achieve "zero carbon" or even "negative carbon" goals. For example, the development of clean power production and carbon reduction technology; analyzing user preferences through efficient digital building, optimizing energy use efficiency and flexibility, and so on.

The wonderful speech and vivid analysis caused a strong response from the audience. Students and "Mr. Sai" interacted with issues such as "nuclear energy use", "new energy vehicle" and "application for the exam".

"The speech of Mr. Sai'er" interpreted the low -carbon concept in a simple interpretation of the low -carbon concept in a simple way, and protecting the ecological environment. From everyone, low -carbon life, low -carbon travel, and work together to contribute to environmental protection! " Huang Qihao, a student of No. 1 Middle School, said.

"Take more public transportation and take the initiative to classify garbage. These seem to be a trivial matter, but they also make a contribution to reducing carbon emissions. Everyone is a practitioner of green and low -carbon life." Dai Shengjia, a student of No. 1 Middle School, said.

"Mr. Sai Sai said 'the theme of carbon emissions in the third issue of this year is an international topic. The speech of the" Mr. Sai "tells the necessity and urgency of the" double carbon "goal. Each of us must be The practitioners of green and low -carbon life. "The majority of netizens said after watching the live broadcast.

"Low -carbon topics are closely related to everyone's lives. Through the" Mr. Sai "'s speech, the low -carbon concept is deeply rooted in the hearts of the people, and calls on everyone to develop the habit of low -carbon life. In the next step, the Suzhou Science and Technology Association will focus on low -carbon themes, Systemic and three -dimensional science popularization low -carbon knowledge, promoting low -carbon concepts. "Zhang Zhijun, member of the party group and vice chairman of the Suzhou Science and Technology Association, said.

The event was co -sponsored by the Suzhou Science and Technology Association, the Suzhou Education Bureau, and the Shanghai Science Popularization Center, and was co -organized by Suzhou Radio and Television Station, the Suzhou Center of the Chinese Academy of Sciences Science and Technology Services Network, and the Suzhou First Middle School in Jiangsu Province."Mr. Sai said" Suzhou Science and Culture Forum

One hundred years ago, the bloody youth raised the banner of "Mr. De" and "Mr. Sai", which set off a new cultural movement that advocated science. Hundred years later, Suzhou established "scientists day" to send out the "Suzhou Suzhou" to the world to respect talents and pay tribute to scientists.declaration".Suzhou has been the hometown of the champion since ancient times, and is now the city of academicians. In such a background, the Suzhou Science and Technology Association innovated in 2020 to host the "Mr. Sai said" Suzhou Science and Cultural Forum.

Today is the 13th event of the "Mr. Sai said" the Suzhou Science and Cultural Forum, and it is also the third issue of 2022.Next, there will be more big coffees such as science and technology, education, economy, culture, and art to bring together Suzhou one after another, and collide with cross -border ideological trends, and condense the surging motivation to promote the high -quality development of Suzhou.
