Including CO2 implications of land occupation in LCAs—method and example for livestock products

  title={Including CO2 implications of land occupation in LCAs—method and example for livestock products},
  author={Kurt Schmidinger and E. Stehfest},
  journal={The International Journal of Life Cycle Assessment},
PurposeUntil recently, life cycle assessments (LCAs) have only addressed the direct greenhouse gas emissions along a process chain, but ignored the CO2 emissions of land-use. However, for agricultural products, these emissions can be substantial. Here, we present a new methodology for including the implications of land occupation for CO2 emissions to realistically reflect the consequences of consumers’ decisions.MethodIn principle, one can distinguish five different approaches of addressing the… Expand

Land use and land use change in agricultural life cycle assessments and carbon footprints - the case for regionally specific land use change versus other methods
Abstract The supply chain of a product is essential for understanding its environmental impacts. As parts of agricultural product supply chains, land use (LU) and land use change (LUC) are consideredExpand

Including GHG emissions from mangrove forests LULUC in LCA: a case study on shrimp farming in the Mekong Delta, Vietnam
PurposeMangrove forests have been recognized as important regulators of greenhouse gases (GHGs), yet the resulting land use and land-use change (LULUC) emissions have rarely been accounted for inExpand
Assessing the edible city: Environmental implications of urban agriculture in the Northeast United States
Food consumption is an important contributor to a city’s environmental impacts (carbon emissions, land occupation, water use, etc.) Urban farming (UF) has been advocated as a means to increase urbanExpand

Impacts of land use change on the assessment of water use in grazing systems and interactions with carbon sequestration.
The impact of land use change (LUC) and water use was investigated using a a case study of beef production from grazing land. LUC from grassland to forest (afforestation) reduced greenhouse gas (GHG)Expand
Climate impacts of land use in LCA - Elaboration of criteria for satisfactory methods
Introduction LCA is a widely used tool for assessing the environmental impacts of products. However, despite the large importance of land use for atmospheric CO2-levels there is still no consensus onExpand
Economics and environmental performance issues of a typical Amazonian beef farm: a case study
Concerns about land use change and the sustainability of beef production are increasing around the world, particularly in the Amazonian region. We intend to improve understanding of economic andExpand
A comparison of Land Use Change models: challenges and future developments
Abstract Land demand is driven by an increasing population and changing consumption patterns. When land is required Land Use Changes (LUC) are triggered, causing several environmental and socialExpand


Key Elements in a Framework for Land Use Impact Assessment Within LCA (11 pp)
AbstractBackground, Aim and Scope Land use by agriculture, forestry, mining, house-building or industry leads to substantial impacts, particularly on biodiversity and on soil quality as a supplier ofExpand
Calculating land use change in carbon footprints of agricultural products as an impact of current land use
Abstract Land use change causes large amounts of greenhouse gas emissions, but there is no generally agreed method yet for attributing those emissions to food products. The so called direct land useExpand
Climatic impact of land use in LCA—carbon transfers between vegetation/soil and air
Background, aim, and scopeHuman use of land areas leads to impacts on nature in several ways. Within the framework of the UNEP/SETAC Life Cycle Initiative, it was stated that life cycle assessmentExpand
Life cycle inventory modelling of land use induced by crop consumption
Background, Aims and ScopeThe actual land use consequences of crop consumption are not very well reflected in existing life cycle inventories. The state of the art is that such inventories typicallyExpand

Indirect Emissions from Biofuels: How Important?
Direct and indirect effects of possible land-use changes from an expanded global cellulosic bioenergy program on greenhouse gas emissions over the 21st century are examined using linked economic and terrestrial biogeochemistry models. Expand
Greenhouse gas emissions from conventional, agri-environmental scheme, and organic Irish suckler-beef units.
Results indicated that moving toward extensive production could reduce emissions per unit product and area but live weight production per hectare would be reduced. Expand
Indirect land use change emissions related to EU biofuel consumption: an analysis based on historical data
Abstract Biofuels have recently been promoted in policies as a way to reduce greenhouse gas emissions from the transport sector. However, biofuel production in itself also induces emissions directlyExpand
Greenhouse gas emissions from biofuels' indirect land use change are uncertain but may be much greater than previously estimated.
Fuel policies that require narrow bounds around point estimates of life cycle GHG emissions are incompatible with current and anticipated modeling capabilities and alternative policies that address the risks associated with uncertainty are more likely to achieve GHG reductions. Expand
