However, the widespread adoption of timber in construction is limited by several factors, including established practices and supply chains, and lack of public policy and incentives to quantify and reduce embodied carbon. The latter needs to be supported by accurate quantitative life cycle assessment (LCA). To identify gaps and challenges faced by LCA development for timber construction, this paper reviews various up-to-date Irish and international LCA practices. At the product level, 26 environmental product declaration (EPD) databases and 35 EPDs covering five wood product types are analysed. At the building level, 29 national and international building LCA methodologies worldwide are compared. Due to varying availability of Irish-customised data, disparities exist between the lifecycle inventory data used in current Irish timber product EPDs and other Irish-focused statistics.

This study models the environmental and economic performances of a set of bus powertrain technologies, considering a real case-study of suburban public transport in Italy, and including fuel cell electric vehicles (FCEV), battery electric vehicles (BEV), biomethane-powered vehicles (CBM), natural gas (CNG), and diesel buses. The environmental performances of FCEV and BEV are significantly influenced by the energy source used for hydrogen production or battery charging. Specifically, using the electricity mix for FCEV leads to the highest greenhouse gas emissions and fossil fuel demand. In contrast, BEV show better environmental performance than conventional powertrains, especially when powered by photovoltaics. When powered by photovoltaics, BEV reveal similar results to FCEV in terms of environmental impacts, except for resource depletion, where both perform poorly. Transitioning from diesel to BEV or FCEV can enhance local air quality, regardless of the energy source. The economic analysis indicates that FCEV are the most expensive option, followed by BEV, both of which are currently costlier than diesel and CNG systems. CBM from waste streams emerges as a cost-effective and environmentally friendly solution. This study suggests prioritizing biomethane derived from biowaste, manure, and residual biomass (excluding energy crops) as a part of the fuels for public transport decarbonization in the EU to advance EU decarbonization goals, despite limitations due to resource availability. Furthermore, BEV powered by renewables should be prioritized whenever their range is adequate.∗</div></div>","PeriodicalId":34616,"journal":{"name":"Cleaner Environmental Systems","volume":"16 ","pages":"Article 100250"},"PeriodicalIF":6.1,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143094094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the growing complexity and variety in construction methods, bridging the gap between theoretical models and real-world practices has become essential. This research addresses these challenges by covering 21 C&D-caused pollutants and identifying existing conflicts through a holistic framework encompassing the entire C&D lifecycle.

A systematic mapping of construction activities with Sustainable Development Goals (SDGs), Green Building Rating Systems (GBRSs), and international standards established a network balancing scientific rigor with multi-stakeholder decision-making. The methodology employed an extended Delphi process, engaging 43 multidisciplinary experts over six months in 2 + 2 rounds, weighting 21 pollutants across nine categories. The findings underscore the primacy of air, noise, and water pollution in regional contexts while revealing conflicts within existing strategies and standards.

Iran ranks among the world's top ten cement producers and is the seventh-largest CO₂ emitter globally. Despite its significant contribution to global emissions, Iran's process-related CO2 emissions (i.e., chemically derived CO2 from calcination) remain underreported in international datasets. This study addresses this gap by analyzing CO₂ emissions from carbonate decomposition in 77 Iranian cement plants from 2013 to 2023, highlighting regional and plant-specific emission factors. Utilizing plant-specific clinker data, the study applied methodologies aligned with the 2006 IPCC Guidelines and the WRI/WBCSD Greenhouse Gas Protocol to calculate emission factors and CO<sub>2</sub> emissions. The findings show notable geographical variations and a substantial national trend, with emissions rising from 28.75 million tonnes (Mt) in 2016 to 39.33 Mt in 2023.

To address this, the study recommends a two-pronged policy approach: reducing clinker content in cement by promoting blended alternatives, such as Portland Composite Cement (PCC) and Portland Pozzolana Cement (PPC), through regulatory controls and economic incentives.
