As part of a state-wide commitment to net-zero emissions by 2050, a draft roadmap has been released outlining how the industry can reach its targets.

"By 2032 we expect the agriculture, fisheries and forestry supply chains will be well on the way to lower emissions production, with the ultimate goal of a net-zero emissions economy by 2050 well in sight," Agriculture Minister Mark Furner said on Wednesday.

In 2018, emissions from the sector contributed 21.2 million tonnes of carbon dioxide equivalent, or 12 per cent of Queensland's total emissions, according to a State of the Environment report released in September last year.

They increased by one per cent between 2005 and 2018, mainly due to emissions associated with beef cattle.

Queensland's agribusiness and food sector is expected to add about $23.54 billion to the state's economy in 2021/22, the roadmap says.

It employs more than 365,000 people across the supply chain, and accounts for more than 13 per cent of Queensland's exports.

To achieve the required reductions, the roadmap points to advancements in livestock feed and fertiliser for crops.

It flags investment in feed and supplements that reduce methane produced by animals in the meat and dairy industries, and the development of green ammonia for fertiliser.

The roadmap also seeks to engage with Australia's Clean Energy Regulator to increase carbon farming options for the state's producers.

The risk of carbon farming can be managed with the government providing greater regulatory certainty, it says.

More training will be needed so landholders can access advice on the merits of selling or retaining carbon credit units.

"The roadmap's priorities are to ensure food security and the economic stability of our food and fibre producing regions while actively transitioning to low emissions agriculture," Mr Furner said.

Feedback on the draft will be open until August 10.
