Implications Of Demographic Policies On China’s Food-Related Environmental Footprints Amid Population Ageing

Objective: To quantify how China’s population ageing and pro-natalist policies will affect future food demand and associated environmental footprints (greenhouse gas (GHG) emissions, land use, water consumption, and eutrophication) by 2050, and to assess the potential of dietary changes to mitigate resulting environmental pressures.

Key Findings:

1. Dominant Role of the Ageing Population: Despite having lower per capita environmental footprints, adults aged 60+ are projected to become the largest contributors to China’s total food-related environmental footprints by around 2040, accounting for approximately 37% by 2050. This shift is driven primarily by the rapid growth in the size of the elderly population.
2. Diverging Footprint Trajectories (2020-2050):

• GHG emissions, water use, and eutrophication are projected to decrease by 26%, 13%, and 12% respectively under a business-as-usual (no new policy) scenario, largely due to assumed technological improvements (declining environmental intensities) and shrinking younger populations.
• Land use footprint is projected to increase by 5%, driven by growing demand for land-intensive products like beef, which is only partially offset by technological gains.

3. Impact of Demographic Policies: Compared to a no-policy baseline, China’s fertility-boosting and age-friendly policies could increase total food-related environmental footprints by 3–18% by 2050. The most aggressive fertility policy (High-Fertility Scenario) results in the largest increase (~18%).

• Land use is the most policy-sensitive indicator. Aggressive pro-natalist policies could delay the peak year of land use footprint by at least a decade, posing a significant challenge to sustainability goals.

4. Potential of Dietary Mitigation: Ambitious nationwide shifts to plant-rich diets (e.g., vegetarian, vegan) could fully offset the policy-induced increases in GHG emissions, land use, and eutrophication footprints.

• Critical Trade-off: Such dietary shifts could lead to higher water consumption footprints, as plant-based foods are often water-intensive. This highlights the need for integrated policy planning.

5. Drivers of Change:

• GHG reduction is primarily driven by technological improvements.
• Changes in the other three footprints are mainly due to dynamic population size and structure (ageing).
• Beef is a critical commodity, being a major and growing contributor to both GHG emissions and, especially, land use footprints.

6. Production-Side Requirements: To fully counterbalance the additional environmental burden from the most impactful demographic policies, China’s food production system would require an additional ~15% improvement in technological efficiency (e.g., benchmarks from leading European nations like Ireland and Denmark).

Conclusions & Implications:

• Integrated Planning is Crucial: China’s demographic policies, while addressing ageing, will create substantial additional pressures on land use and other environmental indicators. These impacts must be explicitly considered in sustainability planning.
• Dual-Strategy Pathway: A combination of demand-side dietary transitions (toward more plant-rich patterns) and supply-side technological acceleration is necessary to mitigate environmental pressures while accommodating population changes.
• Global Supply Chain Effects: Approximately 20-25% of the associated environmental impacts (especially land use and GHG) will occur outside China via international trade, implicating global supply chains and partners in mitigation efforts.
• Model for Others: The study provides a framework for other middle-income countries undergoing similar demographic transitions to assess the environmental trade-offs of their social policies.

Methodology: The study combines an age-cohort demand model (Quadratic Almost Ideal Demand System – QUAIDS) using Chinese nutrition survey data with an environmentally extended Multi-Regional Input-Output (MRIO) model to project food demand and calculate full supply-chain environmental footprints under various demographic and dietary scenarios.

Summary Generated: This executive summary concisely presents the core problem, methodology, key quantitative results, and major policy implications of the study, highlighting the critical tension between demographic objectives and environmental sustainability in China.

• Stakeholder categories (Govt, Enterprise, Public) are broad and may obscure internal heterogeneity (e.g., different types of enterprises).
• Findings are specific to China’s centralized governance context, limiting direct global generalizability.
• Future research should incorporate mixed methods (e.g., interviews, outcome data), conduct cross-national comparisons, and refine stakeholder categorizations for deeper insights.

Summary Generated: This summary captures the study’s core objective, innovative methodology, major findings on policy theme evolution and stakeholder network shift, and its practical and academic implications, highlighting China’s transition towards a more collaborative environmental governance model.

Unpacking The Green Box: Endogenous Preferences And Environmental Policy Stringency In European Countries

Objective:

This study investigates the determinants of Environmental Policy Stringency (EPS) in 21 European countries between 2009 and 2019, with a particular focus on the role of individual environmental preferences—a factor often overlooked in prior literature.

Key Findings:

1. Environmental Preferences Drive Policy Stringency:

• Individual environmental preferences have a positive and statistically significant effect on the EPS index.
• After accounting for endogeneity (using instrumental variables), a 1% increase in environmental preferences leads to a 0.25–0.28% increase in EPS.
• The effect is stronger for market-based instruments (e.g., carbon taxes, trading schemes) and technology-support policies (e.g., green R&D), where elasticities are nearly four times higher than for the aggregate index.

2. Endogeneity Matters:

• Preferences are endogenous to policy: stricter policies also shape public opinion.
• When this two-way causality is addressed using IV methods, the estimated impact of preferences on EPS increases significantly, confirming that OLS estimates were downward-biased.

3. Other Significant Determinants:

• GDP per capita shows a U-shaped relationship with EPS, consistent with the Environmental Kuznets Curve.
• Coalition governments tend to implement less stringent environmental policies compared to single-party governments.
• Control of corruption, international environmental agreements, and climate variables (e.g., heating days) also positively affect EPS.
• Public debt has an inverted U-shaped effect, with an optimal debt level (around 128% of GDP) maximizing EPS.

4. Disaggregated EPS Analysis:

• Preferences significantly affect market-based and technology-based EPS components but not non-market-based instruments (e.g., emission standards).
• Non-market policies are more influenced by international treaties and institutional factors.

5. Robustness:

• Results hold across various model specifications, dynamic panels, and additional controls (e.g., media freedom, trade openness, government types).

Methodology:

• Uses the revised OECD EPS index and its three sub-indices.
• Measures environmental preferences using Eurobarometer survey data (share of respondents ranking climate change as the world’s most serious problem).
• Employs panel data models with fixed effects and addresses endogeneity via instrumental variables (share of students, daily internet use, and unemployment rate).

Policy Implications:

• Governments should proactively shape and respond to public environmental preferences to enhance policy legitimacy and effectiveness.
• Communication and fairness are key: Policymakers must clearly justify environmental measures and ensure costs are distributed equitably to maintain public support.
• International agreements and anti-corruption efforts are important enablers of stringent environmental policy.
• Coalition governments should be aware of their tendency toward weaker environmental policy and seek mechanisms to strengthen commitment.

Conclusion:

The study provides robust evidence that public environmental preferences are a major driver of policy stringency in Europe, especially for market and technology instruments. It underscores the importance of endogenous policy-preference dynamics and calls for more ambitious, well-communicated, and fair climate policies to accelerate the green transition.
