散货船和集装箱)中的二氧化碳排放量实际上增加了1.2%,因为当前全球经济需求的复苏表明2021年航运活动将更加强劲, Marine Benchmark公司表示。
with a 2.4% decline in container emissions offset by growth in the bulker and tanker sectors. However, with Tankers and Bulkers generally performing well。
并利用IMO注册的所有10年以上船舶的每小时AIS数据,而轮渡。
这意味着每消耗一吨燃料会产生3.15吨二氧化碳, the effect may be temporary as the current recovery in global economic demand points to stronger 2021 shipping activity.” The Gothenburg-based company said that vessel CO2 emissions were calculated from the carbon content of the fuel consumed. Marine heavy fuel oil is approximately 86% carbon,其专有算法会根据这些因素估算主要和辅助引擎的船舶燃油消耗, so too are the CO2 emissions per tonne of fuel consumed. Actual vessel fuel consumption depends on a range of factors, 然而,但这种影响可能是暂时的, which implies about 3.15 tonnes of CO2 per tonne of fuel consumed. Since the carbon content of diesel (gas oil) is slightly higher, bulkers,船舶的二氧化碳排放量是根据消耗燃料的碳含量计算出来的,油轮和散装船总体表现良好,滚装船和车辆运输船的急剧下降与需求疲软相符, based on these factors, but primarily the hull, speed and fouling, Marine Benchmark首席执行官Torbjorn Rydbergh指出:“疫情对航运产生了不同影响,规模较小的行业扭转了这一增长趋势, 船舶的实际燃料消耗取决于多种因素,去年全球航运二氧化碳排放量下降了1%, with cruise ship emissions experiencing the greatest contraction – down 45% – and with steep declines in ferries, while other sectors faced headwinds as consumer demand plummeted, the smaller sectors reversed this growth,而其他行业则因消费者需求下降而面临不利因素,” 这家总部位于哥德堡的公司表示, 船用重质燃料油的碳含量约为86%,” Torbjorn Rydbergh, utilising hourly AIS data for all IMO registered ships spanning over 10-years. 。
因此每消耗一吨燃料所产生的二氧化碳排放量也就更高,其中散货船和油轮行业的增长抵消了集装箱排放量2.4%的下降, 2020年全球航运二氧化碳排放量下降1% 2021-03-08来源:中国石化新闻网 石化新闻 中国石化新闻网讯 据3月4日offshore energy消息:根据海事数据提供商Marine Benchmark的数据, as well as hydrological and meteorological conditions. Marine Benchmark said that its proprietary algorithms estimate vessel fuel consumption by main and auxiliary engines, “三巨头”(油轮, noted. “Whilst the overall result is a decrease in carbon emissions for last year, vessel displacement, engine and propeller design,以及水文和气象条件,。
但主要取决于船体、发动机和螺旋桨的设计、船舶排水量、速度和污垢,” “虽然总体结果是去年碳排放减少, and containers – actually increased 1.2%, Marine Benchmark’s CEO,下降45%, 冯娟 摘译自 offshore energy 原文如下: Marine Benchmark: 2020 global shipping CO2 emissions down 1% Global shipping CO2 emissions decreased 1% last year as the Coronavirus pandemic curtailed 2020 shipping activity, roro’s and vehicles carriers consistent with the weak demand. “The Coronavirus pandemic has had a varied effect on shipping,由于疫情减少了2020年的航运活动, 由于柴油(瓦斯油)的碳含量略高,游轮排放量收缩幅度最大, according to maritime data provider Marine Benchmark.
