Optimizing selective breeding of livestock and forage crops to reduce the environmental impacts of grass-based dairy production by combining life cycle assessment and machine learning Open
Global demand for ruminant milk-based products is increasing, contributing to increases in associated environmental impacts. Yet, most efforts to reduce the total environmental impact of dairy production are based on livestock breeding and…

Quantifying Climate Change Effects of Bioenergy and <span>BECCS</span>: Critical Considerations and Guidance on Methodology Open
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). Ho…
National temperature neutrality, agricultural methane and climate policy: reinforcing inequality in the global food system Open
This study critically examines the use of ‘no additional warming’ approaches, such as temperature neutrality (TN), to determine national climate policy on agricultural methane (CH 4 ). The reduced-complexity climate model MAGICC was used t…
Improving biogenic carbon and land use accounting for construction wood Open
Harvested Wood Product (HWP) inventory data in Life Cycle Assessment (LCA) databases are limited in terms of geographical scope. Thus, LCA studies of wood products often neglect important variations in growth rates and wood densities acros…
Exploring the frontier of bovine protein production within territorial net zero emission targets Open
Global and national environmental targets for the Agriculture, Forestry and Other Land Use (AFOLU) sector need to be reconciled with increasing food and protein demands of a growing global population. Meeting climate targets in AFOLU is a …
A life cycle thinking-based environmental risk framework for screening sustainable feedstocks in early-stage bioeconomy projects Open
Understanding the environmental impacts of bio-based feedstock production is essential for sustainable bioeconomy development. Consequential life cycle assessment (LCA) evaluates environmental sustainability, often identifying “hidden” imp…
Delivering More from Land: A Review of Integrated Land Use Modelling for Sustainable Food Provision Open
We conduct a literature review on integrated land use modelling to guide policy on sustainable food provisioning. Modelling approaches are discussed in the spatial, temporal, and human dimensions, as well as environmental and socio-economi…

Duffy et al., (2024). GOBLIN Lite: A National Land Balance Model for Assessment of Climate Mitigation Pathways for Ireland.. Journal of Open Source Software, 9(100), 6732, https://doi.org/10.21105/joss.06732
State-of-the-art in assessing the environmental performance of anaerobic digestion biorefineries Open
Anaerobic digestion (AD) has gained attention in the last decade as a strategic component of the circular bioeconomy (CBE), and Life Cycle Assessment (LCA) has been used to explore the environmental performance of prospective AD-biorefiner…
European soybean to benefit people and the environment Open
Europe imports large amounts of soybean that are predominantly used for livestock feed, mainly sourced from Brazil, USA and Argentina. In addition, the demand for GM-free soybean for human consumption is project to increase. Soybean has hi…
Defining national net zero goals is critical for food and land use policy Open
The identification of agriculture and land use configurations that achieve net zero (NZ) greenhouse gas emissions is critical to inform appropriate land use and food policy, yet national NZ targets lack consistent definitions. Here, 3000 r…
Net Zero requires ambitious greenhouse gas emission reductions on beef and sheep farms coordinated with afforestation and other land use change measures Open
The UK Climate Change Committee has recommended a 64% reduction in greenhouse gas emissions from the agriculture and land-use sector to meet the 2050 Net Zero target in the UK. However, it is unclear how this reduction can be achieved at a…
Can temperate forests deliver both future wood demand and climate-change mitigation? Open
Global wood demand is projected to rise but supply capacity is questioned due to limited global forest resources. Furthermore, the lifecycle global warming potential (GWP) impact of additional wood supply and use is poorly understood. For …
A tasty solution to packaging waste? Life cycle assessment of edible coffee cups Open
Edible cups have been proposed as a solution to littering and plastic pollution arising from disposal of 500 billion beverage cups each year. We applied life cycle assessment and a littering indicator to benchmark the environmental perform…
Circular wood use can accelerate global decarbonisation but requires cross-sectoral coordination Open
Predominantly linear use of wood curtails the potential climate-change mitigation contribution of forestry value-chains. Using lifecycle assessment, we show that more cascading and especially circular uses of wood can provide immediate and…
Improved representation of cattle herd dynamics for bio-physical modelling of pathways to a climate neutral land sector Open
CONTEXT: Livestock production contributes to food security and livelihood improvement globally but places a significant burden on the environment. In Ireland, an ongoing transition towards highly profitable dairy production after the phasi…
View article: Environmental and land use consequences of replacing milk and beef with plant-based alternatives
Environmental and land use consequences of replacing milk and beef with plant-based alternatives Open
The consumption of meat and dairy products raise enormous environmental concerns. Circa 80% of global greenhouse gas emissions (GHG) from the livestock industry originate from beef, milk and pork production. Changing the production and con…
Circular wood use can accelerate global decarbonisation but requires cross-sectoral coordination Open
Productive forestry can deliver multifaceted climate-change mitigation benefits, including carbon sequestration and avoided emissions from fossil-fuel-derived product substitution. However, predominantly linear use of wood substantially li…
Optimising sustainability: Circular pathways for Scotch Whisky distillery co-products Open
The use of co-products for animal feed can potentially have a higher greenhouse gas (GHG) emission and water scarcity offset compared to bio-energy (bio-electricity/fuel) production. We cluster 136 Scotch Whisky distilleries and evaluate t…
Land use and environmental quality in Ireland over two decades of contrasting agricultural trends Open
Global awareness and scrutiny of food production systems, including competition for land between agriculture and nature-based solutions to climate change, has increased immensely recently. In Ireland, around 70% of land area is used for ag…
