National Australia Bank (ASX:NAB) reported a 32% surge in demand for green equipment finance in six months as Australian businesses rapidly shift away from diesel, with uptake in March 2026 more than double the same period last year, according to a Thursday statement by the bank.

The bank said nearly 80% of demand is concentrated in New South Wales, Victoria, and Queensland, with similar efficiency-driven investments emerging across agribusiness, where farmers are increasingly adopting precision spraying technology that targets only green plants, the statement added.

The bank's shares fell past 1% in recent Thursday trade.
