The original and adapted 4PF

AreasRelevanceTopics of the 4PFTopics of the “adapted” 4PF for agricultural SMEsMetrics (with justification) of the adapted 4PF
1. Accessibility, safety and impact on human health of agricultural productsUnsustainable diets – driven by ultra-processed foods high in sugar, sodium and saturated fats – contribute to obesity and non-communicable diseases (Monteiro et al., 2019). Companies are, therefore, encouraged to improve labelling, marketing practices and product safety (Miller et al., 2021)
  • Portfolio of products contributing to healthy and sustainable diets

  • Food security

  • Food safety (safety)

  • Portfolio of products contributing to healthy and sustainable diets

Number of initiatives promoted for sustainable consumption
Directly reflects a company’s proactive role in promoting healthier and more sustainable dietary models through awareness campaigns, educational programmes, partnerships or product-related strategies. By influencing consumer choices, these initiatives contribute to shaping dietary portfolios aligned with public health goals and sustainability imperatives
2. Social and environmental sustainability of operations and internal processesAgriculture is responsible for about 70% of freshwater withdrawals and 26% of EU energy demand (European Commission, 2022), as well as widespread biodiversity loss. Integrating environmental and social dimensions into operations is thus critical for long-term resilience This area matters because sustainability challenges often extend beyond individual firms, requiring companies to engage suppliers and partners in building transparent, responsible and resilient value chains that amplify positive environmental and social impacts (Osei et al., 2023)
  • Non-discrimination and equality

  • Health and safety at work

  • Decent wages and income

  • Animal welfare

  • Training

Total training hours for employees/total number of employees Captures the company’s commitment to workforce development, capacity building and equal access to learning opportunities, which are critical to fostering inclusion and innovation in SMEs
3. Corporate commitment to promoting a sustainable supply chain and value creation
  • Non-discrimination and equality

Percentage of women over total employees

  • Sustainable agricultural production

Total energy consumption/revenues
Provides a measure of resource efficiency, linking production sustainability with economic performance
  • Climate change and air quality

Total Scope 1 GHG emissions/revenues
Quantifies climate impact relative to firm size, enabling comparability and assessing progress in emission reduction
  • Water resources

Total water consumption/revenues
Indicates the intensity of water use per unit of economic output, a key issue in viticulture where irrigation is critical
  • Supply chain sustainability

Percentage of local supply expenditure over total supply costs
Assesses the firm’s contribution to local economies and the promotion of sustainable, short supply chains, which reduce environmental impacts and strengthen community relations
  • Governance and management

Percentage of women in governance
Reflects diversity and inclusivity at the decision-making level, enhancing governance quality and legitimacy
