With climate change accelerating, dietary shifts, particularly in rapidly expanding Asian economies, are emerging as a critical player in global climate solutions. A recent study delves into how consumers in China, Japan, and Vietnam are balancing their love for traditional foods with a growing interest in eco-friendly choices. This exploration uncovers insights that could pave the way for more sustainable diets across the region.
The Impact of Sustainable Diets
Shifting to more sustainable diets is one of the most effective ways to cut global greenhouse gas emissions and ease the strain on land and water resources. Experts agree that reducing the consumption of resource-intensive animal proteins, such as beef, can significantly benefit both the planet and our health.
While countries in South and East Asia have traditionally leaned on plant-forward diets, the demand for animal protein is skyrocketing. By 2030, meat consumption is expected to grow by 75% in Vietnam and 20% in China compared to 2010 levels. This trend underscores the urgency of promoting sustainable eating habits in these regions.
Exploring Consumer Readiness in Asia
Most research on reducing meat consumption has focused on Western countries, where strategies like food labeling and education campaigns have proven effective. However, little is known about whether similar approaches would work in Asian markets. The study conducted by Research and Advocay Officer Elena Schaller explores how ready consumers in China, Japan, and Vietnam are to embrace more sustainable eating habits.
Researchers surveyed over 5,000 people across the three countries to understand their food habits and awareness of environmental issues and health concerns associated with meat production. They also asked how much people would pay for food certified as environmentally friendly.
Methodology and Findings
To dig deeper, participants were presented with “food baskets” filled with different items that varied in sustainability and price. These foods considered food culture and habits and included meat, vegetables, fruits, and starch staples like rice or bread. Participants could also choose a meat-free option. The researchers then tested whether providing educational “nudges” could influence their choices. Participants were randomly divided into groups and exposed to one of three nudges or no nudge at all (the control group):
- Climate Impact Nudge: Explained how the growing demand for meat contributes to increased greenhouse gas emissions.
- Resource Use Nudge: Highlighted the environmental toll of intensive farming.
- Health Effects Nudge: Emphasized risks from fertilizers and pesticides used in intensive agriculture.
Each nudge ended with a statement about the ability of the participant’s personal choices to make a difference.
The survey was delivered face-to-face in China and Vietnam and online in Japan. Participants were recruited from both urban and rural areas in each country, and the sampling was designed to represent population demographics in terms of age, gender, and household income to investigate country-level effects.
Key Insights
- Protein Preferences: Chicken and fish were the most popular protein choices, with people willing to pay 2% more for them compared to pork. Beef was slightly less popular, and lamb was the least preferred.
- Carbohydrate Choices: Rice was the clear favorite, with consumers willing to pay 7% more for rice than bread or potatoes.
- Sustainable Labeling: Food labeled as sustainable was well received across all three countries, with participants being willing to pay roughly 16% more for a food basket with items that were certified as sustainably produced. Vietnamese consumers stood out, being willing to pay 39% more for eco-friendly options.
- Demographic Differences: Younger and wealthier participants were the most interested in sustainable options and willing to pay more for them. Older and rural consumers responded better to health-focused messages.
- Trust in Certification: 84% of consumers trusted certified environmental labels, with international organizations being trusted the most. Participants in China and Vietnam expressed the most trust in government certification schemes (50%), while Japanese participants were the least trusting of these (26%).

The Effectiveness of Nudges
The nudges didn’t significantly reduce the consumption of less sustainable proteins like beef and pork. However, they did slightly increase interest in chicken and fish, particularly the greenhouse gas emission and health-related message. This suggests that promoting better choices may be easier than discouraging worse ones.
Implications for Advocates
While many Asian consumers are reluctant to reduce their animal protein intake, there’s growing concern for the environment. The strong interest in food certification shows that people are open to sustainable choices, especially when they’re seen as trustworthy and high quality.
Creating meaningful change will require more than awareness campaigns or nudges. A comprehensive approach will combine culturally tailored strategies, reliable certification programs, and improved access to affordable sustainable options. Together, these efforts could help lower the environmental footprint of diets in these diverse markets.
As consumers, we have the power to drive change through our food choices. By supporting sustainable practices and advocating for reliable certification programs, we can collectively reduce our environmental footprint. Let’s embrace this shift and contribute to a healthier planet, one meal at a time.
