Mitigation of China’s carbon neutrality to global warming

Abstract

Projecting mitigations of carbon neutrality from individual countries in relation to future global warming is of great importance for depicting national climate responsibility but is poorly quantified. Here, we show that China’s carbon neutrality (CNCN) can individually mitigate global warming by 0.48 °C and 0.40 °C, which account for 14% and 9% of the global warming over the long term under the shared socioeconomic pathway (SSP) 3-7.0 and 5-8.5 scenarios, respectively. Further incorporating changes in CH4 and N2O emissions in association with CNCN together will alleviate global warming by 0.21 °C and 0.32 °C for SSP1-2.6 and SSP2-4.5 over the long term, and even by 0.18 °C for SSP2-4.5 over the mid-term, but no significant impacts are shown for all SSPs in the near term. Divergent responses in alleviated warming are seen at regional scales. The results provide a useful reference for the global stocktake, which assesses the collective progress towards the climate goals of the Paris Agreement.

Spatially Non-Stationary Response of Carbon Emissions to Urbanization in Han River Ecological Economic Belt, China

“…Xi Jinping, president of the People's Republic of China, proposed that "China will strive to contribute autonomously to peak carbon dioxide emissions before 2030 and achieve carbon neutrality before 2060" at the United Nations General Assembly in 2020. The proposal of the "30•60 dual carbon" goal has pushed low-carbon development and green transformation to the crossroads of a historical turning point [10].…”

“…In addition, the burning of fossil fuels releases a large number of pollutants (e.g., methane, carbon dioxide, and nitrous oxide) into the atmosphere, thus causing serious environmental and ecological predicaments, such as global warming, greenhouse effects, and acid rain. 1 The hazards caused by fossil fuels not only contribute to the long-term negative impacts on the health of the planet but also have short-term effects on human health. In view of the overconsumption of fossil fuel reserves and the resulting ecological issues, the search for alternative renewable sources is extremely urgent and necessary.…”

“…Nevertheless, fossil fuels represent nonrenewable energy sources that confront the peril of resource depletion attributable to excessive human exploitation and utilization. In addition, the burning of fossil fuels releases a large number of pollutants (e.g., methane, carbon dioxide, and nitrous oxide) into the atmosphere, thus causing serious environmental and ecological predicaments, such as global warming, greenhouse effects, and acid rain . The hazards caused by fossil fuels not only contribute to the long-term negative impacts on the health of the planet but also have short-term effects on human health.…”

Zinc‐Supported Nitrogen‐Rich Carbon Catalyst for Efficient Carbon Dioxide Cycloaddition with Epoxides under Solvent‐Free Conditions

“…The continuous progress of industrial technology and the increase of population resulted in a dramatic growth in energy demand in the past several decades. To fulfill the world's energy demand, the excessive consumption and combustion of fossil fuels increased the emissions of greenhouse gas (GHG) proportion in the atmosphere, especially for carbon dioxide (CO 2 ), which has caused the disastrous consequences including global warming, ocean acidification and climate change [1,2] . Nevertheless, CO 2 is known as an inexpensive, abundant and readily available C1 building block for the synthesis of a series of high value‐added chemicals [3,4] .…”

[3,4] As a result, the converting and reuse of CO 2 into high-value chemicals have aroused great attention of global scientists and emerged as the hot topic research of green chemistry engineering.…”
