Grand Challenge - emissions from agricultural production is of major environmental concern on a global scale.

Emissions from agricultural production is of major environmental concern on a global scale due to:

• ecosystem effects (eutrophication and soil acidification) caused by ammonia.
• health threats due to formation of secondary aerosols from ammonia and sulfur compounds.
• global warming by the greenhouse gases, nitrous oxide and methane.
• formation of tropospheric ozone from volatile organic compounds (VOC).
• local odor nuisance caused by a range of odorants.

On a European level, agriculture contribute e.g. 95 per cent of ammonia emissions and 10 per cent of the greenhouse gas impact. There is currently a strong incentive in EU to cut emissions by 2030 of e.g. ammonia by 27 per cent, methane by 33 per cent and VOC by 50 per cent.

AU is developing and optimising new cost-effective technologies for achieving low-emission emission technology including air treatment, source treatment, ventilation design and new detection systems for emission control.
