“…ReCipe 2016 Midpoint method, which integrates the midpoint assessment of CML-IA and the endpoint assessment of Eco-indicator 99, is selected as the impact assessment method. ReCipe 2016 Midpoint method contains the widest range of midpoint impact categories, allowing for the application of characterization factors within these categories at an international scale [34].

Membrane gas absorption technology has been considered as a promising approach to mitigate CO2 emissions from power plants. The aim of this study is to evaluate the environmental impacts of CO2 absorption and desorption processes by hollow fiber membrane contactors using life cycle assessment methodology. On the basis of ReCipe 2016 Midpoint and ReCipe 2016 Endpoint methods, the research results show that, membrane gas absorption system exhibits the lowest environmental impacts across the majority assessed categories in comparison with chemical absorption and membrane gas separation systems. The CO2 capture process via membrane gas absorption has the most significant impact on METP category, with heat consumption as the primary contributing factor accounting for 55%, followed by electricity consumption accounting for 43.1%. According to the sensitivity analysis, heating by natural gas shows a better performance than other heat supply sources in improving overall environmental impacts. In addition, the increasing utilization of renewable energy in electricity supply reduces the global warming potential, fossil resource consumption and ozone formation.

“…The approach of Roy et al builds on earlier work demonstrating the use of SRMs for LCA. 24,[66][67][68] The air quality models GEOS-Chem, CMAQ, and CAMx feature similar coverage of pollutants and F&T mechanisms. Each model uses emissions data as input, which in all three cases includes industrial and mobile sources, biomass burning, agricultural emissions, and dust, with the flexibility to include additional sources.…”

This paper evaluates the current state of life cycle impact assessment (LCIA) methods used to estimate potential eutrophication impacts in freshwater and marine ecosystems and presents a critical review of the underlying surface water quality, watershed, marine, and air fate and transport (F&T) models. Using a criteria rubric, we assess the potential of each method and model to contribute to further refinements of life cycle assessment (LCA) eutrophication mechanisms and nutrient transformation processes as well as model structure, availability, geographic scope, and spatial and temporal resolution. We describe recent advances in LCIA modeling and provide guidance on the best available sources of fate and exposure factors, with a focus on midpoint indicators. The critical review identifies gaps in LCIA characterization modeling regarding the availability and spatial resolution of fate factors in the soil compartment and identifies strategies to characterize emissions from soil. Additional opportunities are identified to leverage detailed F&T models that strengthen existing approaches to LCIA or that have the potential to link LCIA modeling more closely with the spatial and temporal realities of the effects of eutrophication.

“…(19) For chemical emissions to outdoor media, impact characterization draws from risk assessment (RA) principles by accounting for a chemical's release, transport, fate, human exposure, and toxicological effects when arriving at a potential impact metric. (20)(21)(22)(23)(24) Efforts to develop assessment methods for the impacts of exposures to indoor and workplace sources primarily focus on extending the human toxicity assessment approaches developed for far-field sources to include near-field media such as indoor air and other exposure routes such as dermal uptake. (3,11,16) However, these methods often do not address some of the choices made when the far-field methods were first developed.…”

Life Cycle Assessment (LCA) is a decision-making tool that accounts for multiple impacts across the life cycle of a product or service. This paper presents a conceptual framework to integrate human health impact assessment with risk screening approaches to extend LCA to include near-field chemical sources (e.g., those originating from consumer products and building materials) that have traditionally been excluded from LCA. A new generation of rapid human exposure modeling and high-throughput toxicity testing is transforming chemical risk prioritization and provides an opportunity for integration of screening-level risk assessment (RA) with LCA. The combined LCA and RA approach considers environmental impacts of products alongside risks to human health, which is consistent with regulatory frameworks addressing RA within a sustainability mindset. A case study is presented to juxtapose LCA and risk screening approaches for a chemical used in a consumer product. The case study demonstrates how these new risk screening tools can be used to inform toxicity impact estimates in LCA and highlights needs for future research. The framework provides a basis for developing tools and methods to support decision making on the use of chemicals in products.
