Idea of killing cows to curtail methane emissions 'crazy'
Visiting US climate change expert Dr Will Happer says the idea of reducing cow numbers to greatly reduce methane emissions is crazy.
By 2025, capsules delivering a methane-inhibiting substance into the stomachs of livestock could significantly reduce the country's greenhouse footprint.
That's the goal of Waikato-based Ruminant BioTech. Repurposing the slow-release pills used to deliver medicines to livestock, the start-up created a proprietary capsule that it says reduced cattle-made methane by 90% for months.
Although the trials are at an early stage and haven't been published, the start-up said its goal now was to deliver a commercially viable product that can cut methane by 70% over six months.
