Queen's University Belfast is working with farmers to co-create solutions to reduce their carbon footprint, including carbon storage and sequestration.
It is widely understood that methane emissions from livestock is a significant contributory factor to climate change. Recent research in Australia and the US identified a red seaweed variety that saw an 80% reduction in methane emissions when added to cattle’s feed in small quantities. This seaweed only grows in tropical areas and contains high levels of bromoform – known to be damaging to the ozone layer. Researchers at Queen’s have focused on finding a local seaweed alternative that produces similar results but doesn’t pose a risk to the ozone layer or require transportation and the associated carbon footprint.
The research at Queen's has shown promising results using native Irish and UK seaweeds. Sharon Huws, Professor of Animal Science and Microbiology at Queen’s, is expecting the combined research to evidence a reduction in GHG emissions of at least 30%.

- Researchers at Queen’s have been feeding native seaweed supplements to cattle in a bid to reduce methane emissions by at least 30%.
- Researchers at Queen’s are assessing the nutritional value of homegrown seaweeds, their effects on animal productivity, and meat quality.
- Early laboratory research has shown promising results in terms of reducing methane emissions. Due to increased levels of iodine in the milk of seaweed-fed cows, researchers are now embarking on dairy trials, providing this milk to people with iodine deficiencies.
