Enhanced rock weathering supply chain life cycle sustainability

Grantham Scholar Eunice Oppon is now Lecturer in Business Analytics at University of Exeter Business School. At the Grantham Centre she researched the sustainability of enhanced rock weathering by measuring economic, environmental and social impacts.

Research has found that speeding up the naturally occurring process of the weathering of rock to draw CO2 out of the atmosphere could help to significantly stabilise the climate and avert ocean acidification caused by humans burning fossil fuels. This is referred to as ‘enhanced rock weathering’.

The supply chain of the enhanced weathering process will require the mining, comminution, transportation and application of these silicate rocks in targeted areas to result in significant draw-down in CO2. My research looks into ensuring sustainability of the process by measuring the economic, environmental and social impacts.

Along with her fellow Grantham Scholar Jonas, Eunice Oppon worked on a Defra funded project about food waste. As part of this, she and Jonas came up with a new approach that considers both the social impact of the food redistribution and the resource value of food.

Eunice published on ecologically unequal exchanges between the UK and Africa. She explained this paper for us. Read: Ecologically unequal exchange through trade: paper.

Grantham Scholars – Jonas CromwellGloria MensahYe Jiang, and Eunice Oppon – went to Anne Grove Primary School in Sheffield to talk to the kids there. Their aim? To try help reduce food waste in schools. Look here for the blog they wrote about their work.
