Projecting mitigations of carbon neutrality from individual countries in relation to future global warming is great importance for depicting national climate responsibility but poorly quantified. Here, we show that China's (CNCN) can individually mitigate by 0.48 °C and 0.40 °C, which account 14% 9% the over long term under shared socioeconomic pathway (SSP) 3-7.0 5-8.5 scenarios, respectively.

Assessing Representative CCUS Layouts for China’s Power Sector toward Carbon Neutrality

Environmental Science & Technology, Год журнала: 2021, Номер 55(16), С. 11225 - 11235

Опубликована: Июль 29, 2021

China's carbon neutrality target is building momentum for capture, utilization, and storage (CCUS), by which the power sector may attain faster decarbonization in short term. However, an overall CCUS pipeline network blueprint remains poorly understood. This study, first time, links China TIMES model ChinaCCUS Decision Support System 2.0 to assess representative layouts toward neutrality, with level of deployment maximum transportation distance from emission sources sites considered. The total length proposed under low, medium, high levels are about 5100, 18,000, 37,000 km, annum CO

Regional trade agreement burdens global carbon emissions mitigation

Nature Communications, Год журнала: 2022, Номер 13(1)

Опубликована: Янв. 20, 2022

Abstract Regional trade agreements (RTAs) have been widely adopted to facilitate international and cross-border investment promote economic development. However, ex ante measurements of the environmental effects RTAs date not well conducted. Here, we estimate CO 2 emissions burdens Comprehensive Economic Partnership (RCEP) after evaluating its effects. We find that among RCEP member countries will increase significantly output expand with reduction regional tariffs. results show complete tariff elimination members would yearly global from fuel combustion by about 3.1%, doubling annual average growth rate in last decade. The some developing surge. In longer run, can be lessened extent technological spillover deeper liberalization. stress advancement more effective climate policies are urgently required avoid undermining efforts reduce emissions.

Role of climate goals and clean-air policies on reducing future air pollution deaths in China: a modelling study

The Lancet Planetary Health, Год журнала: 2022, Номер 6(2), С. e92 - e99

Опубликована: Фев. 1, 2022

BackgroundOver 3 million people die every year from diseases caused by exposure to outdoor PM2·5 air pollution, and more than a quarter of these premature deaths occur in China. In addition clean-air policies that target pollution emissions, climate aimed at reducing fossil-fuel CO2 emissions (eg, avoid 1·5°C warming) might also greatly improve quality public health. However, no comprehensive accounting health outcomes has been done under different energy pathways local management decisions We develop an integrated method for quantifying the co-benefits climate, energy, policy scenarios assess relationship between future burdens China, where ageing population will further exacerbate effects pollution.MethodsFor this modelling study, we used China-focused assessment model dynamic emission projection project Chinese spanning range global targets (1·5°C, 2°C, national determined contributions [NDC], unambitious, baseline, 4·5°C) actions (termed 2015-pollution, current-pollution, ambitious-pollution). then evaluated scenario matrix using latest epidemiological concentration–response functions 2019 Global Burden Diseases, Injuries, Risk Factors Study.FindingsWe found that, without ambitious mitigation current NDC pledge), related not always decrease—and often grow—by 2050 compared with base 2015, regardless improvements. For example, tracks China's pledge uses best available control technologies (the ambitious-pollution goals scenario), PM2·5-related China would decrease slightly 2030 1·23 per (95% CI 0·95–1·51) 1·25 (1·04–1·46) but (1·21 million, 0·86–1·60) despite substantial continuous improvements population-weighted (from 27·2 μg/m3 16·0 2050). The contrary trends improving increasing many our revealed extent which extra efforts are needed compensate age future. With included met international 2°C warming ambitious-pollution-2°C ambitious-pollution-1·5°C observed decreases 0·32–0·55 2050, age-standardised death rates decreased 10·2–14·2 100 000 year.InterpretationOur results show (ie, limiting average temperature rise well below 2°C) low-carbon transitions coupled stringent necessary substantially reduce human socioeconomic assumptions.

China’s electric vehicle and climate ambitions jeopardized by surging critical material prices

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Март 4, 2023

Abstract The adoption of electric vehicles (EVs) on a large scale is crucial for meeting the desired climate commitments, where affordability plays vital role. However, expected surge in prices lithium, cobalt, nickel, and manganese, four critical materials EV batteries, could hinder uptake. To explore these impacts context China, world’s largest market, we expand enrich an integrated assessment model. We find that under high material cost scenario, EVs would account 35% (2030) 51% (2060) total number significantly lower than 49% 67% share base-line, leading to 28% increase cumulative carbon emissions (2020-2060) from road transportation. While recycling technical battery innovation are effective long-term countermeasures, securing supply chains through international cooperation highly recommended, given geopolitical environmental fragilities.
