Graham is an Environmental Scientist by training with a passion for Life Cycle Assessment (LCA), Systems Thinking, Nutritional Science, Sustainability Trade-off Analyses, and Scientific Communication. His career-focus to date has largely centred on methodological improvements to LCA, including the quantification of various uncertainties and the consideration of nutritional composition and quality of a range of food items within the burgeoning field of nutritional LCA (or nLCA). Graham is a Sustainability Science Leader at Unilever, endeavouring to support the provision of high-quality produce with minimal impacts, as well as maximum benefits, to nature and society. Graham's scientific interests cover most aspects of commodity-based sustainability (primarily in the area of food), including but not limited to: cradle-to-plate "hotspot" identification of various pollutants and their environmental impacts, e.g., methane's effect on global warming; development of novel and/or site-specific emission factors and quantifying their effect at the system-scale; devising new approaches to integrate spatial heterogeneity into the LCA framework, for instance using Geographical Information Systems (GIS), to assess impacts to nature from differing farming systems at the catchment scale; exploring trade-offs between different sustainability metrics; merging sustainability metrics (e.g. as per nLCA and animal welfare considerations) to elucidate better understandings of risks and benefits associated with different food products in terms of both human and environmental health. Having consulted for the United Nations' Food and Agriculture Organization (FAO) division on the implementation of nutritional metrics into the LCA framework, one of Graham's primary focusses is on delivering informative sustainability models whilst acknowledging that there are often high degrees of uncertainties involved along the entire supply/value chain of various food commodities. As countries around the world strive to achieve net zero greenhouse gas emissions (as well as other critical sustainability concerns including supporting rural economies, protecting waterbodies from pollutants, and providing globally equitable nutrition), LCA can be useful when used appropriately and communicated clearly; however, the complexities of system-scale modelling are often overly simplified. Graham strives to enhance methods of such models whilst improving their communication to deliver transparent and robust advice to key stakeholders.
