Market Mechanism And Focus Of International Cooperation To Achieve Carbon Neutrality, Lele Zou, Pu Wang, Yi Sun

Bulletin of Chinese Academy of Sciences (Chinese Version)

The market mechanism is the basis for achieving carbon neutrality. Through the market mechanism, the global cost can be the lowest to achieve carbon neutrality. Therefore, in the process of carbon neutralization, it is necessary to give full play to the decisive role of the market in resource allocation. China has explored and accumulated experience in various market mechanisms for more than 10 years, and has established the carbon market, green certificate market, white certificate market, energy market, etc. At the same time, the power system is also strengthening market-oriented reform. Nevertheless, there are still imperfect systems and conflicts among …

Carbon Neutrality Policy Measures In Global Major Economies, Jianfang Wang, Liyang Su, Xianchun Tan, Xiaoyi Chen, Chunlei Ge

Bulletin of Chinese Academy of Sciences (Chinese Version)

This study focuses on the strategies, targets and policy measures for carbon neutrality in global major economies. The research shows that due to the different socio-economic and political foundations, the transition strategy towards carbon neutrality in major economies is also varied, which can be divided into four categories:leading strategy, growth strategy, following strategy, and swing strategy. Most of them build carbon neutrality target system with the framework of "target roadmap+targets in key areas", but leading countries usually integrate targets into legislation and thus the objective is legally binding, while others tend to weaken emission reduction targets and focus on the …

Technological Approaches To Enhance Ecosystem Carbon Sink In China: Nature-Based Solutions, Guirui Yu, Jianxing Zhu, Li Xu, Nianpeng He

Bulletin of Chinese Academy of Sciences (Chinese Version)

Carbon peak in 2030 and carbon neutralization in 2060 has been established as one of the important strategic goals of China's economic and social development. During 2010-2020, the capacity of terrestrial ecosystems in China to sequester carbon dioxide (CO2) varied from 1.0 to 1.3 Gt/a, with high uncertainty. To enhance the carbon sink capacity of Chinese terrestrial ecosystems, the combination with land space planning and ecological protection is essential. It is necessary to first stabilize the existing carbon storage in these ecosystems, such as forest, grassland, wetland, coast, and others, and then implement some important ecological protection and ecological restoration …

Global Climate Change Driven By Marine Methane Hydrate Dissociation: Reality Or Fiction?, Yige Zhang

Sustainability Seminar Series

Methane hydrate dissociation has long been considered as a mechanism for global carbon cycle perturbations, climate change and even mass extinctions in Earth’s history. However, direct evidence of hydrate destabilization and methane release that coincides with such events is scarce. We use diagnostic lipid biomarkers directly linked to methanotrophic microorganisms to track the dissociation of gas hydrates in Earth’s Cenozoic history. We show biomarker and compound-specific isotope evidence of methane release and oxidation at several climate change events, suggesting that aerobic oxidation of methane in seawater which consumes oxygen and acidifies the ocean is a key process that drives climate …

Use Of Insar In Linear Discontinuous Ground Deformation Generation Analysis: Case Study Of A Mine In Poland, Bartosz Apanowicz

Journal of Sustainable Mining

Linear Discontinuous Ground Deformations are defined as fissures and steps, as well as structural forms composed of them. They occur on the surface as a result of underground mining. Knowledge of LDGDs has been acquired through field observations which are subsequently described in the scientific publication. Records of LDGDs are made by using the classic surveying method. The paper reviews the created LDGDs in the years 2015–2019 in one of the mines of the USCB. The analysis covers the velocity of subsidence as a result of underground mining and the values of horizontal strains determined according to the Knothe-Budryk theory. …

Think Of The Future: From Nonrenewable To Sustainable, Froyzee Rey Eduard Armena

Symposium of Student Scholars

Abstract

When seawater evaporates, it becomes rainwater that you can store and use later on. The resources available on earth are immeasurable, yet it takes so much time for it to replenish its usable state, just like the ocean. When I drive through cities, I’m always in awe of being constantly reminded how the human race has progressed. The rate at which we progress concerns me, do we have enough power to fuel the future? Are the resources we can tap in from support the amount of research we do? This research aims to assess our energy reserves that seem …
