Cultured meats, precision fermentation and other cutting-edge technologies are predicted to disrupt conventional agriculture. Despite the threat, New Zealand is well positioned to ride the wave.
Cows and sheep produce lots of the greenhouse gas methane.

Seaweed is in the spotlight for so many reasons. It all sounds too good to be true. So can this wonder weed live up to expectations and fulfill its promise to save us from ourselves?
The budget earmarked worthwhile climate measures, but many are piecemeal. Amid record-breaking extreme weather in Australia, federal spending on climate action still falls well short.
The agriculture and fossil fuel industries are the biggest sources of methane emissions in Australia. Here’s how signing the pledge may affect them.
Climate researchers stress that natural gas bridges can often lead to nowhere as the reliance on natural gas can lock countries into fossil fuels, crowd out low-carbon technologies and risk stranding assets.

Fossil fuel companies are winning the battle on how we talk about natural gas expansion by referring to it as a “bridge fuel” or an essential bridge to the net-zero energy system of the future.
Cow burps are a major contributor to methane emissions.

If the UK government is to cut methane emissions by 30% before 2030, it needs fewer cows and more crops.

As one of the few countries to have enshrined net-zero into law, Canada has earned praise for its climate leadership. Yet an independent report calls out its continued failures to reduce emissions.
Reducing methane emissions could slow global warming quickly and buy time for the world to wean itself off fossil fuels. But it must not distract from the challenge to cut carbon dioxide emissions.

Un discours simpliste tenu par des activistes, des célébrités, des philanthropes, des décideurs politiques voudrait que « tous les animaux d'élevage soient mauvais ». Ce qui est loin de la réalité.

A simplistic ‘all livestock are bad’ narrative is promoted by campaigners, celebrities, philanthropists and policymakers alike. A much more sophisticated debate is needed.
Scientists are learning trees can emit methane, which could be a big problem for global warming. But a world-first discovery of methane-eating bacteria in paperbark can help moderate this.
Scientists previously underestimated aquatic methane emissions. We must use this new information to stop methane derailing our attempts to stabilise the Earth’s temperature.
If agricultural land was used to grow crops, it would limit methane emissions from livestock, but not store a substantial amount of carbon. Growing trees is what makes the difference.
