Carbon Footprinting and LCA
Run by School of Natural Sciences
20 Credits or 10 ECTS Credits
Organiser: Dr David Styles
Overall aims and purpose
This module is designed to provide knowledge, understanding and capacity to undertake carbon footprinting (CF) and life cycle assessment (LCA) for professionals concerned with the sustainable and efficient management of land resources. The key components of the global carbon cycle and greenhouse gas fluxes associated with agricultural production and the food and fibre supply chain will be reviewed. Emphasis will be placed on the importance of soils, ruminants, fertilizers, transport and energy consumption, with a focus on fluxes of CH4 and N2O as well as CO2. The range of international protocols for CF and challenge of determining appropriate emissions factors will be reviewed. The methods to identify emission hotspots within production and supply chains and to test alternative scenarios for their reduction will be addressed.
While concentrating on carbon and greenhouse gases, the coverage of LCA will also address the assessment of other key ecosystem services including regulation of water and air pollutants. Particular attention will be paid to the methods of assessment of the impacts of land use change.
Through lectures and structured learning with hands-on exercises and extensive on-line resources, the module will provide a theoretical and critical analysis of the practice and application of CF & LCA as key tools in assessing the environmental impact of land use systems.
The global carbon cycle and greenhouse gas fluxes associated with agricultural production and the food and fibre supply chain.
The key roles of soils, ruminants, fertilizers, transport and energy consumption as sources of CH4, N2O and CO2 emissions.
International protocols for carbon footprinting (CF) and determination of emissions factors.
Methods to identify emission hotspots within production and supply chains and scenario testing.
Life cycle assessment of carbon, greenhouse gases, water and pollutants, including the challenge of limitation of primary data sources, and reliability of secondary data.
Assessment of land use change.
Be able to demonstrate knowledge of the principles of carbon footprinting and life cycle assessment (CF & LCA), their key components and how they are used to assess the environmental impacts of land use and food/fibre production systems. Be able to use guidelines to carry out simple CF & LCA analyses using data provided. Be able to interpret the outputs of CF & LCA analyses and draw conclusions about the relative impacts of alternative land use systems, to a descriptive level.
In addition to above, show appreciation of the limits of available data sources for LCA, the methods required to obtain primary data and the challenges of accessing sufficiently reliable secondary data. Be able to demonstrate an ability think critically about the assumptions in CF & LCA, including the key role of emissions factors and the practical implications of this uncertainty.
In addition to the above, be able to independently undertake a CF & LCA of a UK land use system and food production system, including the acquisition and utilization of appropriate secondary data, identifications of emission hotspots and scenario analyses. Be able to present well reasoned arguments for and against particular approaches to CF & LCA of land use and food production systems. Be able to critically appraise the potential management and policy applications of CF & LCA. Present clear evidence of wide reading around the subject and an ability to analyse and synthesise arguments and information.
Describe quantitatively the major sources of greenhouse gas emissions and other environmental burdens arising from livestock production.
Describe the rational and procedures of carbon foot-printing and life cycle assessment (CF and LCA) showing knowledge of the main available tools.
Calculate carbon footprints for key stages of livestock production, including manure management, fertiliser manufacture and application, feed production, enteric fermentation and carbon sequestration using IPCC methods.
Critically evaluate the results of freely available carbon footprinting tools.
Show a critical understanding of the application and role of CF & LCA in the improvement of the sustainability and efficiency of food production.
