Conceptual issue of the dynamic GWP indicator and solution

The International Journal of Life Cycle Assessment, 2022
PURPOSE : Dynamic LCIA has been developed in the past 12 years almost exclusively for climate change impact assessment, and especially the Global Warming Potential (GWP) indicator. Recently, discussions have taken place in France on the issue of integrating, a dynamic GWP indicator in the 2020 regulation (noted RE2020) on new buildings. This regulation

The Role of Environmental Metrics (GWP, TEWI, LCCP) in the Selection Of Low GWP Refrigerant

Energy Procedia, 2014
AbstractBased on increasing contribution of refrigeration systems to climate change it is necessary to use environmentally friendly refrigerants to mitigate the global warming. Different environmental metrics are used to facilitate decision-making process of selection of refrigerant with low global warming potential.

GWP*is a model, not a metric

Environmental Research Letters, 2022
To aggregate different greenhouse gases, the UNFCCC common reporting formats, the IPCC inventory guidelines, and the Paris Agreement rulebook use an emission metric that has been around for more than 30 years: the Global Warming Potential (IPCC, 1990).

Thermophysical Properties of Low GWP Refrigerants: An Update

International Journal of Thermophysics, 2023
AbstractIn the last decades, the industry of HVAC&R has faced continuous changes trying to identify environmentally friendly refrigerants for the numerous applications of the sector. However, the amount of low GWP fluids still available as potential refrigerants is limited to some natural fluids and, among synthetic chemicals, to hydrofluoroolefins

Demonstrating GWP*: a means of reporting warming-equivalent emissions that captures the contrasting impacts of short- and long-lived climate pollutants

Environmental Research Letters, 2020
The atmospheric lifetime and radiative impacts of different climate pollutants can both differ markedly, so metrics that equate emissions using a single scaling factor, such as the 100-year Global Warming Potential (GWP _100 ), can be misleading.

Overview of low GWP mixtures for the replacement of HFC refrigerants: R134a, R404A and R410A

International Journal of Refrigeration, 2020
The current European F-gas regulation establishes restrictions in the use of fluoride refrigerants with a high global warming potential (GWP) in applications of refrigeration and air conditioning (RAC) systems.

Review of low-GWP refrigerant pool boiling heat transfer on enhanced surfaces

International Journal of Heat and Mass Transfer, 2019
Global warming mitigation efforts have stimulated investigations of a new generation of low-GWP refrigerants. Because some of the proposed low-GWP refrigerants have unfavorable characteristics (e.g., flammability and toxicity), a small refrigerant charge

Identification and Removal of Negative Biomass Samples via Scatter Plot Analysis to Improve GWP Predictive Modeling [PDF]

E3S Web of Conferences
Accurate prediction of Global Warming Potential (GWP) from biomass constituents is essential for evaluating the sustainability of bioenergy sources. However, the inclusion of biomass samples with weak or negative correlation to key elemental components ...

Thermodynamic Evaluation of Low-GWP A1 Refrigerants for Ultra-Low Temperature Refrigeration Applications

Energies
Slow market development has caused the lack of low-GWP A1 refrigerants for ultra-low temperature (ULT) refrigeration. Consequently, the high-GWP refrigerant R23 (GWP = 14,600) remains widely used within the ULT sector.

Testing GWP* to quantify non-CO2 contributions in the carbon budget framework in overshoot scenarios [PDF]

npj Climate and Atmospheric Science
The Global Warming Potential-star (GWP*) approach is a way to convert the emissions of short-lived climate forcers to CO2-equivalent emissions while maintaining consistency with temperature outcomes.
