- Ammonium nitrate fertilizer used in wheat cultivation contributes 43 per cent of greenhouse gas emissions in a loaf of bread
- 100 million tonnes of fertiliser used globally every year
- Findings vital to providing solutions to global food security challenge
With an estimated 12 million loaves sold in the UK every day, bread remains a staple of the British diet. In a groundbreaking study researchers from the University of Sheffield have now calculated the environmental impact of a loaf of bread and which part of its production contributes the most greenhouse gas.

It is widely accepted that global food production will have to increase
dramatically over the coming decades to meet the needs of growing
populations and developing economies, and that this will be increasingly
difficult as we feel the effects of climate change. Intensive agriculture
is currently unsustainable so a different path is needed. Sustainable
intensification is heralded as the saviour of agriculture but what
does it mean in practice? This paper sets out a model that combines
the lessons of history with the benefits of modern biotechnology, to
redesign sustainability in intensive agriculture.

Experts point to damage caused by erosion and pollution, raising major concerns about degraded soil amid surging global demand for food.
“We have the technology. We just need the political will to give us a fighting chance of solving this problem.” ~ Prof. Duncan Cameron
