Unlocking Climate Solutions: How Boosting Aquatic Food Consumption in China Can Cut Greenhouse Gas Emissions

China’s aquatic food sector plays a crucial role in the global food landscape. Understanding its greenhouse gas (GHG) emissions is key to evaluating its impact on the environment and nutrition.

The overall carbon footprint of China’s fisheries is calculated by subtracting the carbon sinks from total GHG sources. Carbon sinks include shellfish and algae that can absorb significant amounts of carbon from seawater. In contrast, GHG emissions arise from production and transportation processes, including fishing vessels and machinery used in aquaculture. Recent estimates suggest that direct emissions from these sources are substantial, yet indirect emissions from energy usage in food processing and transport also contribute significantly.

An interesting aspect of aquatic food production is that it is generally more sustainable than terrestrial animal meat. Fish and shellfish offer higher protein content with lower environmental costs. According to data from the Food and Agriculture Organization (FAO), aquatic food consumption per person in China was clocked at just 13.9 kg/year in 2020—well below the global average of 20.5 kg/year. This indicates an opportunity for growth in the consumption of these nutritious foods.

A study from 2021 examined the potential impacts of increasing aquatic food consumption in three scenarios: maintaining current consumption levels, boosting freshwater food intake, and increasing seawater food consumption. These scenarios aim to project how enhanced aquatic food consumption could align with carbon neutrality goals.

Furthermore, the environmental advantages of aquatic foods become clearer when compared to terrestrial meat and eggs. Aquatic foods tend to produce fewer GHG emissions per unit of protein. By increasing aquatic food consumption, China may significantly reduce its GHG emissions profile, thereby supporting global sustainability efforts.

In a survey, many consumers expressed a growing interest in seafood, not only for its nutritional benefits but also for its lower carbon footprint compared to other protein sources. This shift in consumer attitudes reflects broader social media trends emphasizing health and sustainability.

In conclusion, enhancing aquatic food consumption presents a promising pathway for improving nutrition while also addressing environmental concerns. The shift toward seafood could lead to more sustainable dietary patterns, aligning with the United Nations’ Sustainable Development Goals (SDGs) aimed at providing sufficient nutrition for all.
