Research Overview

The claim–practice gap in local café culture

Cafés have evolved into influential social spaces where sustainability is increasingly performed — biodegradable cups, reusable container programs, ethical sourcing stories, and waste-reduction campaigns. Yet as even microenterprises adopt eco-friendly messaging to attract conscious consumers, the consistency between what cafés say and what cafés do remains largely unexplored in Northern Mindanao.

Objectives of the Study
  1. 1Identify sustainable green practices adopted by coffee businesses in Northern Mindanao across green marketing, product sourcing, and waste disposal.
  2. 2Determine key factors influencing the adoption of sustainability initiatives by coffee businesses.
  3. 3Analyze customer-perceived awareness of sustainable green practices and eco-friendly offerings.
  4. 4Evaluate the degree of claim–practice alignment in sustainable green marketing.
  5. 5Produce an evidence-based framework mapping perceived sustainability alignment among microenterprises.
What gap does this study address?

Prior research examined what drives small businesses to adopt sustainability — finances, manager commitment, consumer awareness. Little work measures whether environmental marketing messages match operational implementation in the café industry.

Why cafés in Northern Mindanao?

The Western District of Misamis Oriental hosts a fast-expanding food-and-beverage microenterprise scene and a green coffee market valued at USD 1.3 billion, driven by urban café culture, e-commerce coffee sales, health awareness, and specialty coffee demand (Rebecca, 2026).

What will the findings be used for?

Results form the basis of an action plan and policy recommendations for transparent, evidence-based sustainability marketing — supporting municipal policy, business support programs, and UN SDG 11 sustainable urban development in the region.

Study Area & Methodology

Western Misamis Oriental, Northern Mindanao

The Western District — ten municipalities and cities with a dense concentration of food-and-beverage microenterprises, growing tourism, and rising demand for eco-friendly goods and services.

Research Design

Mixed-methods: quantitative descriptive-correlational design describing current green initiatives and testing links between drivers, practices, and perceptions.

Sampling

Purposive (cafés ≥3 years open, ≥1 eco-practice, Western Misamis Oriental) plus opportunistic customer recruitment. n = 100 for data saturation.

Instrument

Four-section structured questionnaire: demographics, sustainability drivers, green marketing practices, and consumer perceptions — 5-point Likert, expert-validated and pilot-tested.

Statistical Treatment

Frequency, percentage, mean, SD; Pearson r or Spearman rho for relationships; multiple regression for impact — all at α = 0.05.

Respondent composition
n = 100 sample

Balanced sampling for claim–practice alignment comparison

Questionnaire items by section
60 Likert items

Statements per section across Consumers (21), Owners (23), & Workers (16)

Research Instrument

Finalized Questionnaire

Three structured instruments — consumers, café owners & managers, and workers & baristas. Each follows the proposal's four-section format on a 5-point Likert scale (1 = Strongly Disagree → 5 = Strongly Agree). Answer interactively, then copy the responses or print the instrument.

Theoretical Foundations

Three lenses on sustainability signaling

FREEMAN, 1984

Stakeholder Theory

Organizations adopt responsible environmental practices to create shared value across customers, employees, suppliers, regulators, and communities. Café sustainability initiatives answer stakeholder demands for environmental accountability.

SPENCE, 1973

Signaling Theory

Certifications, eco-labels, and promotional messages communicate sustainability, shaping consumer trust and purchasing decisions by reducing information asymmetry between cafés and their patrons.

AJZEN, 1991

Theory of Planned Behavior

Attitudes, subjective norms, and perceived behavioral control shape consumers' intentions to engage in environmentally responsible purchasing behavior.
