Abstract：
As the world\'s demand for textiles and clothing rapidly increases, this industry\'s greenhouse gas (GHG) emissions are becoming a major environmental concern. Bangladesh, a key player in the global textile supply chain and one of the top producers, contributes significantly to these emissions. However, accessible data on activity and GHG emissions, crucial for researchers, the private sector, and policymakers in decision-making, is scarce. To address this gap, this study combines a detailed field survey with expert interviews to establish a comprehensive emission inventory. This inventory aims to identify hotspots and facilitate the adoption of effective mitigation strategies. Focusing on a prominent industrial zone\'s textile and readymade garments (RMG) industries, the research employs a mix of top-down and bottom-up approaches and follows the IPCC guidelines to develop a GHG emission inventory for 2022. The study evaluates various emission sources, including scope 1 (onsite fuel combustions), scope 2 (grid electricity usage), and scope 3 (waste and wastewater treatment). In the total emissions (6043.5 Gg CO2eq.), textile and RMG industries contribute 67.8% and 32.2%, respectively, with scope 1 emissions dominating at 85%. Notably, scope 2 emissions exhibit significant uncertainty (-10.4% to +11.9%), largely due to variations in national grid emission factors. This study forecasts GHG emissions until 2030, considering current trends (26 thousand Gg CO2 eq.). It also explores various energy mix scenarios, factoring in the depletion of existing natural gas reserves (ranging from 8 thousand to 33 thousand Gg CO2 eq.). This study delves into the impact of the Environmental, Social, and Governance (ESG) system on industries\' GHG emissions. Besides improving worldwide emission databases and identifying hotspots, this research aims to promote a sustainable transition in both Bangladesh and other developing textile manufacturing nations across the globe.
摘要：
随着世界对纺织品和服装的需求迅速增加，该行业的温室气体(GHG)排放正在成为一个主要的环境问题。孟加拉国,全球纺织品供应链中的关键参与者和顶级生产商之一对这些排放做出了重大贡献。然而,关于活动和温室气体排放的可访问数据，对研究人员来说至关重要，私营部门和决策者参与决策，是稀缺的。为了解决这个差距，这项研究将详细的实地调查与专家访谈相结合，以建立全面的排放清单。该清单旨在确定热点并促进采用有效的缓解策略。专注于一个突出的工业区的纺织和成衣(RMG)产业，该研究采用自上而下和自下而上的混合方法，并遵循IPCC指南，制定2022年温室气体排放清单。该研究评估了各种排放源，包括范围1(现场燃料燃烧)，范围2(电网用电)，和范围3（废物和废水处理）。在总排放量(6043.5GgCO2eq。),纺织和RMG行业贡献了67.8%和32.2%，分别,范围1的排放量占85%。值得注意的是,范围2排放表现出显著的不确定性(-10.4%至+11.9%)，主要是由于国家电网排放因子的变化。这项研究预测了到2030年的温室气体排放量，考虑到目前的趋势(2.6万Gg二氧化碳当量。).它还探索了各种能源组合方案，考虑到现有天然气储量的枯竭(二氧化碳当量从8千到33千克不等。).这项研究深入研究了环境的影响，社会,工业温室气体排放治理(ESG)系统。除了改善全球排放数据库和识别热点，这项研究旨在促进孟加拉国和全球其他发展中的纺织制造国家的可持续转型。
