The city is currently undergoing a transition in its industrial sectors and optimizing its energy structure, both developments that have achieved notable successes, and sees a trend of decreasing total carbon emissions. However, along with accelerating urbanization and an increasing population, emissions from oil consumption in the transportation sector will further exacerbate problems of air pollution and environmental degradation for the foreseeable future. According to historical data on Hangzhou’s emissions, current carbon emissions from the city have already reached periodic peak. As a result of transformations in industry, clean power, and the closure of coal-fired power plants, carbon emissions increased and then subsequently decreased in recent years, carbon intensity continues to decrease, and the proportion of indirect emissions from electricity surpassed coal in 2016, becoming the largest source of carbon emissions. Emissions reductions from industrial sectors are currently the primary cause of decreasing carbon emissions. However, with increases in the marginal cost of energy-saving measures and an economic uptick, there are signs of a rebound in carbon emissions. In recent years, transportation has played an increasingly significant role in rebounding carbon emissions. Considering Hangzhou’s current oil consumption structure, transportation accounts for the most gasoline and diesel fuel usage. As the city’s economy has developed and its main urban area expanded, the number of vehicles has remained high and the potential for continued oil consumption growth remains, leading Hangzhou to implement policies to limit an increase in carbon emissions. Measures to cap oil consumption not only contribute to reducing greenhouse gases and extreme weather occurrences, but also have a positive impact on managing pollution and traffic congestion. Hangzhou has seen major advancements in its digital economy and firmly grasps the opportunities that big data and artificial intelligence offer to establish an “urban brain” and smart city. Successful implementation of an oil cap project is a necessary path for Hangzhou to realize low-carbon development. 11 油控情景下杭州市碳减排路径研究 This research sets three scenarios (reference, low-carbon, and oil cap) that consider different levels of low-carbon development in energy and industrial transitions, building, transportation, and daily living, among other areas. Under the oil cap scenario, oil consumption will peak in 2023 at approximately 5 million tons (around 7 million tons of standard coal equivalent). The following timetable for the phase-out of traditional fuel vehicles in Hangzhou was produced according to the oil cap project’s national phase-out timetable and proposal to ban traditional fuel vehicle sales. Proposed Hangzhou Traditional Fuel Vehicle Phase-Out Timetable Type Hangzhou traditional fuel vehicle phase-out timetable National traditional fuel vehicle phase-out timetable proposed by the China Oil Cap Project Bus 2016 2030 Coach 2035 2045 Freight vehicle 2040 2050 Taxi 2020 2030 Private car 2030 2040 This research utilizes the LEAP model to calculate the future carbon emissions levels in Hangzhou and the carbon emissions and energy use from various sectors for the reference, low-carbon, and oil cap scenarios. The major conclusions are: 1. Hangzhou has reached periodic carbon emissions peak Under the reference scenario, considering a significant population influx, large-scale activities, and relatively fast economic development, carbon emissions will continue to slowly increase from 2020 to 2025 as part of the rebounding trend. After 2025, as energy efficiency and the industrial structure improve, carbon emissions will decrease. 2. Transportation and buildings are key sectors for future emissions reductions Contributions to emissions reductions will primarily come from secondary industries, as the greatest areas for growth are in the transportation and building sectors. Along 油控研究项目系列报告 12 with economic development and the acceleration of urbanization, transportation sector emissions will become increasingly significant, making measures to control oil consumption in this sector crucial. 3. Oil consumption to face effective controls under oil cap scenario Under the oil cap scenario, electricity will account for 68% of the energy consumption structure, and coal consumption (not including power generation) will decrease to under 2% by 2050. The consumption of oil will decrease further. By 2050, the share of oil in final energy consumption will fall to 4%, as compared to 19.4% in 2017, with the amount consumed dropping 81.8%. 4. Air quality to see fundamental improvements PM 2.5 is the major component of Hangzhou’s air pollution. Of the PM 2.5 pollution in the region, NOx and SO 2 emissions play a significant role and primarily result from traditional fuel vehicles and burning coal, as required for thermal power and the cement industry. The oil cap scenario predicts oil consumption in 2030 will decrease approximately 38% relative to 2015, while coal consumption will drop 62%. Considering advances in emissions treatment technologies and the trend towards cleaner oil products, it is possible to reach the target of decreasing NOx and SO 2 emissions 40% by 2030. 5. Carbon emissions will gradually decouple from economic growth The Hangzhou carbon emissions decoupling index illustrates that, under the oil cap scenario, the city will enter a phase of strong decoupling after 2020, as emissions decrease and the economy continues to grow. The analysis of Hangzhou’s peak carbon emissions from transportation indicates that carbon emissions will continue to increase for a certain period of time under each of the scenarios. The reference scenario predicts a peak in 2028, while the low-carbon and oil cap scenarios both set the date for 2025. Under the oil cap scenario, as the industrial use of oil decreases and transportation undergoes electrification, oil consumption will decrease significantly by 2050. In the transportation sector, freight and non-commercial vehicles (primarily passenger cars) will be key emissions areas. This report thoroughly investigates oil cap measures and policies suited to the specific 13 油控情景下杭州市碳减排路径研究 conditions of Hangzhou. These will establish limits on motor vehicle travel, guide residents towards green transportation usage, optimize the effectiveness of transport organizations, and improve energy efficiency. Divided into strategies to “reduce, shift, optimize, and upgrade,” these four methods aim to strictly control oil consumption and realize the targets set forth in the oil cap scenario. 1. “Reduction” Strategy This strategy intends to optimize the city layout through integrating both land-use and transportation planning, establish a balanced commercial-residential development model for the region, and reduce the demand for motorized transport. 2. “Shift” Strategy These measures plan to develop green transportation and shift travel from private passenger vehicles to energy-efficient public, non-motorized, and shared transport methods. 3. “Optimization” Strategy The “optimization” strategy will utilize modern communication channels, the internet, and other technological measures to optimize travel efficiency and reduce fuel consumption. 4. “Upgrade” Strategy This strategy intends to reduce oil consumption through improving energy efficiency and expanding alternative energy usage. According to the oil cap pathway analysis, a phased implementation plan for Hangzhou should prioritize strong measures that will produce immediate reductions in fuel consumption. Transportation constitutes a complicated system that must ensure efficient and orderly travel. This is the premise for multi-sector participation and support for comprehensive measures that will achieve the goal of peak oil consumption in 2023. 1 杭州控油减排背景和意义15 油控情景下杭州市碳减排路径研究 1.1 应对气候变化 近 10 年来,杭州市经历了快速的经济发展和城市扩张,经济快速转型。但同时也 面临交通拥堵、极端天气多发等众多问题。杭州市目前在应对气候变化领域开展了成效 卓著的工作,并且碳排放总量出现下降趋势,但随着城镇化进程的加快,人口的增长, 未来会面临由此导致的空气污染等严峻问题。 1. 杭州市低碳发展经验 近年来, 在全球变暖的大背景下, 台风、 强降水等极端天气事件发生的频率不断增加, 给人类的生存带来极大的挑战。杭州市不断深化气候低碳发展理念,把低碳发展作为经 济社会发展的重大战略和生态文明建设的的重要途径, 采取积极措施, 积极应对气候变化。 早在2004 年, 杭州市就印发了 《优先发展城市公交, 缓解市民 “出行难” 问题的实施意见》 , 坚持“公交优先”发展战略,在构建完善公交系统、增强公交运力、改善公交服务质量 等方面做了大量工作,助力低碳交通发展;2010 年,杭州被国家发改委确定为全国首 批低碳试点城市,提出打造低碳经济、低碳交通、低碳建筑、低碳生活、低碳环境、低 碳社会“六位一体”的低碳示范城市;2017 年,杭州市人民政府印发《杭州市“十三五” 控制温室气体排放实施方案》,进一步明确低碳发展总体目标、战略任务,切实深化低 碳建设。 2. 碳排放总量先升后降,碳强度持续下降 2010-2016 年杭州市能源活动二氧化碳核算排放总量呈现“倒 U 型”变化趋势。 2010-2014 年 CO 2 核算排放量总体增长,增速震荡收窄,并于 2014 年达到最高点, 随后受电力排放因子调整、杭钢半山基地关停,以及主城区电厂燃煤机组淘汰等因素的 影响,从 2015 年开始全市核算排放量出现负增长。
