A critical systematic review of MCDA/MCDM applications in bioenergy sustainability assessment: Methodological gaps and challenges for comparable decision-making

Akram Jahanshahi, Miguel Brandão, Sina Ataee, Mohammadreza Khalaj et autres

Substitution

Miguel Brandão, Bo P. Weidema

As by-products are often co-produced with the determining products, the resulting system will be a multi-product system. Because LCA studies are typically concerned with the impacts of one specific (determining) product, there is a need for a procedure to reduce multi-product systems …

Decision support

Miguel Brandão

Life cycle assessment (LCA) has been recognized as an important environmental systems analysis tool due to its potential for providing systematic results about the environmental impacts of alternative production and consumption systems that can lead to decisions towards greater sustainability in both …

Physical allocation

Miguel Brandão, Bo P. Weidema

According to the ISO standards, all types of allocation should be avoided. Allocation excludes the parts of the product system that are related to the co-products, the fate of the excess production of by-products, and the decrease in the marginal supply to …

Cascading wood use into bioenergy with carbon capture and storage ensures continuous and enduring temperature reduction

George D. Bishop, Colm Duffy, Göran Berndes, Miguel Brandão et autres

Abstract Bioenergy with carbon capture and storage (BECCS) is a key component of pathways to net zero, yet potential interactions with forest carbon dynamics, cascading wood strategies, and progressive decarbonisation and CCS deployment are poorly represented in assessments. Here, using dynamic life …

Methods for quantifying and incorporating biomass carbon sequestration by trees in life cycle assessments

Muhammad Ahmed Waqas, Fatemeh Hashemi, Lisbeth Mogensen, Miguel Brandão et autres

Abstract Purpose Global temperatures are expected to surpass the critical threshold of 1.5 °C above pre-industrial levels by 2040, necessitating the urgent need for large-scale and sustained carbon dioxide (CO 2 ) removal. Tree-based systems offer a promising solution for carbon (C) …

On the use of national-level LULUC data in product-level LCA: reflections on methodological alignment

Miguel Brandão, Bo P. Weidema, Jannick Schmidt

We read with interest the recent publication by Lehtilä and colleagues [1], which proposes a framework for including national-level land use and land-use change (LULUC) emissions and removals in the global warming potential (GWP) of agricultural and forestry products in life cycle …

Quantifying Climate Change Effects of Bioenergy and BECCS : Critical Considerations and Guidance on Methodology

Annette Cowie, Kati Koponen, Anthony Benoist, Göran Berndes et autres

ABSTRACT Bioenergy is a critical element in many national and international climate change mitigation efforts, including as a carbon dioxide removal strategy combined with the capture and durable geological storage of flue gas emissions (BECCS). However, divergent results on the effectiveness of …

Comparative life cycle assessments of stand-alone and integrated green hydrogen and biofuel value chains: A case study on drop-in biocrude, biohydrogen and biomethanol production systems

Richard Kingsley Padi, Victor Paredes González, K. Maran, Miguel Brandão et autres

Biofuel production systems integration with green hydrogen (e.g., from proton exchange membrane electrolysers- PEM) can enable product yield improvements (e.g., gasification based biomethanol via hydrogenation of carbon-oxides) or co-production of synthetic methanol through hydrogenation of captured CO 2 . Environmental impact of …

Toward eco-friendly menstrual products: a comparative life cycle assessment of sanitary pads made from bamboo pulp vs. a conventional one

Azadeh Mirzaie, Miguel Brandão, H. Zarrabi

The predominant menstrual products utilized by women are sanitary pads. The majority of disposable sanitary pads are comprised of plastics and bleached wood pulp, often accounting for as much as 90% of their composition by weight. Nevertheless, the overall environmental footprint of …

Carbon Removal Accounting for a Sustainable Future: Distributing CO2 Flows in Multiservice Systems

Gonzalo Rodriguez-García, Miguel Brandão, Robert P. Anex

Carbon dioxide removal (CDR) systems are an integral part of sustainable pathways limiting global warming to less than 2.0 °C. When the sole purpose of CDR is capturing and storing atmospheric CO2, carbon registries offer detailed procedures to calculate the carbon removal …
