Veganuary: Why meat-free meals could be the key to tackling climate challenges

It may be the time of year for celebrations and resolutions, but this week also marked the start of Veganuary - a month-long campaign encouraging meat-eaters to switch to plant-based foods. With this in mind, edie explores the full environmental and social impacts of the animal protein industry, and what the global business community is doing to reduce our reliance on it.

The global livestock industry accounts for 15% of the world's carbon emissions, and uses 83% of all existing agricultural land

After a month of indulging in festive fare, thousands of us will have set a resolution to eat healthier this year. Indeed, LinkedIn chief executive Jeff Weiner has estimated that around seven in ten Brits will have resolved to diet this month.

For many, that will involve eating less meat and dairy and more fresh produce - but for others, January is a chance to ditch animal-based products altogether. Launched in the UK in 2014 by a team of environmentalists, the Veganuary campaign challenges participants to eat only vegan foods for 31 days, with a view that they will change their dietary habits in the long-term.

Never ones to miss a trend, business giants ranging from McDonald's to Marks & Spencer (M&S) have launched new product ranges to coincide with Veganuary, but will moving into an emerging market create environmental benefits as well as economic opportunities for business?

Carbon versus calories 

In a drive to encourage members of the general public to join in, green campaign groups often push the ethical case for veganism, displaying footage of cramped conditions in factory farms and inhumane practices at slaughterhouses. But there is also a climate case for making the switch to plant-based cuisine.

The need to tackle the climate impact associated with the human consumption of meat and dairy is significant, with GHG emissions from the livestock sector estimated to account for 15% of the global total. This figure is set to hit 80% of the planet’s carbon budget by 2050 as the global population grows to reach 10 billion people – who will need to be fed in in a more sustainable way than at present.

The global meat sector is widely classed as a key contributor to climate change – and one of the worst-prepared industries for climate challenges such as droughts, floods and heatwaves in the world.

Indeed, none of the industry’s major corporates have aligned themselves with the Paris Agreement’s flagship goal of limiting the world’s temperature increase to 1.5C, with only 28% of the world’s largest 60 intensive farming firms having to set any plans for climate risk mitigation.

Wider problems

Away from emissions, large-scale deforestation, fires, and human rights abuses in Argentina and Paraguay’s Gran Chaco region have been linked to meat producers across the globe.

Moreover, producing meat and dairy products is an extremely water-intense process. The IME claims that producing 1kg of meat requires between 5,000 and 20,000 litres of water, compared to around 500-4,000 litres of water for 1kg of wheat.

With water requirements for food production set to reach around 10-13.5 trillion cubic metres per year by 2050 - about triple the current amount used annually by humans for all purposes - reducing our reliance on animal-based proteins has been posited by several experts as an effective way to combat water scarcity and preserve natural resources.

Globally, meat provides just 18% of the calories consumed by humans each year – but its production takes up 83% of all existing farmland.

As for the social sustainability piece of the puzzle, the World Economic Forum (WEF) has estimated that the amount of diet-related deaths could be reduced by 5% in developed nations if citizens eliminated beef from their diets.

It is perhaps not surprising, then, that Oxford University has dubbed veganism as the “single biggest way” for a person to reduce their negative impact on the planet.

Planting the seeds for a new vegan era

The good news is that, as consumer awareness of the environmental and ethical challenges posed by the global meat, seafood and dairy industry rises across the globe, the number of people identifying as vegan in the UK has increased by 350% since 2008, according to research by the Vegan Society.

Similar trends in consumption have been tracked across the world, with veganism having grown by 600% in the US over the past three years and the amount of Portuguese citizens identifying as vegetarian and vegan having quadrupled since 2008.

In China, meanwhile, the government is encouraging citizens to halve their meat consumption – a recommendation that has led experts to predict that the nation’s vegan market will grow by 17% by 2020. And in Hong Kong, 22% of the population is already practising some form of a plant-based diet.

This shift in demand for plant-based food has led to a boon in the vegan milk market, which is estimated to have grown to reach $16bn in 2018, up dramatically from $7 billion in 2010.

The wider alternative proteins market is now on a similar trajectory, with Coller Capital’s FAIRR initiative estimating that the global market for alternative plant-based proteins could expand at an annual rate of 8.29% in the next three years and reach $5.2bn by 2020.
