Agriculture contributes significantly to greenhouse gas emissions and there is a need for identifying viable long term reduction steps that farmers can adopt. Scientists Dumbrell et al. identified the greenhouse gas mitigation potential and the costs of abatement at three Australian grain farms located in the main grain growing regions of Australia. They found marked difference in abatement potential and impact on operating profits across case study farms and management practices. Reaching significant climate change abatement will come at a cost to farmers.
