Prince Charles’ prize backs face mask that cuts methane emissions from cow burps

A device that fits around the face of cattle and cuts methane emissions from their burps has won a £50,000 (€59,502) award backed by the British royal, Prince Charles.

The mask was designed by students from the Royal College of Art in the UK, who were one of four teams to be chosen as winners of the inaugural Terra Carter Design Lab competition. The prize money will go towards further developing their idea.

The device converts methane emitted by cows and was created by a design group called the Zero Emissions Livestock Project (ZELP). It neutralises methane emissions in real-time and fits around the cow's head in a way that doesn’t impact its ability to feed and interact with the herd.

Gases captured by the mask are oxidised using a catalyst and then released into the air as CO2 and water vapour. Its designers say that data is also captured throughout the life of the animal to help optimise welfare on farms, improve productivity and create a ‘robust’ log of greenhouse gas emissions.

Burped out by dairy and beef herds, methane is 80 times more warming than CO2 during its first 20 years in the atmosphere.

There are around 1.6 billion cattle on the planet and each produces up to 400 litres of methane a day. Emitted via belching or farting, this makes them significant contributors to the problem of global warming.

The prize is funding solutions to confront the climate crisis

Prince Charles visited the new Terra Carta Design Lab at the Royal College of Art in London to meet the winners. At the event he said that climate change has led to “crises confronting us in all directions,” and “finding solutions rapidly” was important.

The Prince praised the designers' creativity adding that with it “we will have a better chance of winning this battle in a shorter time”.

“We can all have good ideas,” added Sir Jony Ive, Chancellor of the Royal College of Art.

“I find it reassuring, particularly facing the overwhelming challenge of climate change, that we can all contribute ideas that could evolve into valuable solutions. I love not only the power of a good idea - but how egalitarian and inclusive they can be.”

Francisco Norris, founder of the mask startup, says that winning the Terra Carta Design Lab is a “huge honour” for ZELP.

“This is the perfect platform to accelerate a climate solution with a strong design element, and we are eager to continue optimising our technology with the endorsement and the support of the Terra Carta.”

Addressing the largest source of methane emissions and delivering a substantial global emissions reduction is key, he adds.

“We remain as motivated as ever to scale our solution and play a part in the decarbonisation of the agricultural sector.”

The need to limit global warming as much as possible

Climate change will result in thousands of new viruses spreading among animal species by 2070 and that's likely to increase the risk of emerging infectious diseases jumping from animals to humans, according to a new study.

This is especially true for Africa and Asia, continents that have been hotspots for deadly disease spread from humans to animals or vice versa over the last several decades, including the flu, HIV, Ebola and COVID-19.

Researchers, who published their findings on Thursday in the journal Nature, used a model to examine how over 3,000 mammal species might migrate and share viruses over the next 50 years if the world warms by 2C.

They found that cross-species virus spread will happen over 4,000 times among mammals alone. Birds and marine animals weren't included in the study.

Study co-author Colin Carlson, who was also an author on the latest report from the Intergovernmental Panel on Climate Change, said we must cut greenhouse gas and phase out fossil fuels to reduce the risk of infectious disease spread.

Jaron Browne, organising director of the climate justice group Grassroots Global Justice Alliance, said the study highlights climate injustices experienced by people living in African and Asian nations.

“African and Asian nations face the greatest threat of increased virus exposure, once again illustrating how those on the frontlines of the crisis have very often done the least to create climate change," Browne said.
