The emissions calculation data set was collated by the Carbon Neutral Grain Pilot Project, backed by the WA government, Co-operative Bulk Handling (CBH) Group and Wide Open Agriculture.

The information will enable growers to understand their own grain emissions and respond to increasing global market demand for grain from low emissions production systems.

The data set was based on 36 case studies of grain enterprises with greenhouse gas emissions calculated from wheat, barley, canola, oats and lupin production, and compares emissions calculators.

The initiative complements the state's $4.24 million investment in the Katanning, WA, Research Station demonstration site to help farmers create more sustainable businesses.

Agriculture and Food Minister, Alannah MacTiernan, said WA grain growers can now confidently calculate their own on-farm greenhouse gas emissions and adapt their operations to satisfy customer requirements for low emissions food and fibre products.

"It is great to see CBH Group and Wide Open Agriculture join together with the Department of Primary Industries and Regional Development (DPIRD) on this project which lays sound foundations for growers to remain ahead of the game," MacTiernan said.

"There is no denying the market signals from the global marketplace and this important resource will help our grain growers to remain internationally competitive and profitable," the Minister said.
