A recent study by researchers at James Cook University in Queensland, Australia, has found a certain type of Australian red algae can significantly inhibit methane emissions from cows.

In June 2019, the UK became the first major world economy to set a target for achieving net zero on greenhouse gas (GHG) emissions into law, with then Prime Minister Theresa May committing the UK to net zero emissions by 2050.

At COP26 this month, 105 countries including the US, Canada and Brazil promised to reduce their methane gas emissions by at least 30% within eight years.

The basis of the narrative around the push to cull cattle is that cows produce methane, and that’s true

Methane is a greenhouse gas with dual personalities. It heats Earth’s atmosphere 28 times as potently as carbon dioxide, gram for gram. But its absorption of the sun’s radiation high in the atmosphere also alters cloud patterns — casting a bit of shadow on its warming effect.
