As environmental concerns reshape business strategies, firms increasingly engage in sustainability programs. However, research has found that although consumers report caring about the environment, a wide gap exists between their attitudes and behavior. Given the substantial costs of manufacturing and certifying products that meet ESG standards, a fundamental question persists: Can firms achieve financial success by aligning their operations with environmental initiatives? This study explores whether firms can reconcile environmental responsibility with profitability by conducting cost-benefit analyses of Amazon’s CPF program.
The study leverages proprietary data from a leading Amazon seller spanning January 1, 2023, to January 31, 2024. This dataset includes granular product-level details such as page visits, orders, revenue, price promotions, reviews, and CPF program participation status.
To assess the company’s benefit from participating in the CPF program, the researchers estimate the causal impact of the CPF program on consumer behavior. They employ a synthetic difference-in-differences (SDID) approach to compare the outcomes of products before and after obtaining the CPF badge, between CPF products and synthetic products generated from the control group. Additionally, LLM-driven analysis of customer reviews helps uncover the underlying drivers of consumer decision-making. Using data on annual certification costs and profit margins, the researchers conduct cost-benefit analyses to evaluate the financial viability of the CPF program.
The CPF badge successfully increased product page visits by 5.44%, indicating heightened consumer interest. However, the corresponding rise in orders was only 3.46%, leading to a net decline of 0.2 percentage points or 3.3% in the conversion rate. This gap between consumer interest and actual purchase behavior aligns with prior research on the attitude-behavior gap in green consumption.
Analysis of consumer reviews reveals the increased awareness of the product’s eco-friendly feature contributed to the heightened consumer interest in CPF products. However, consumers perceived CPF products to be higher priced and of lower quality, which explains why consumer interest in sustainable products failed to translate into proportionate actual purchases.

The financial viability of Amazon’s CPF program for participating firms is essential for its long-term sustainability. Further cost-benefit analyses show that, for nearly all products, joining the CPF program did not generate sufficient profits to offset the certification costs and deliver significant financial benefits to the company, due to the attitude-behavior gap. However, over 70% of products would not only break even, but also generate substantial gains of 10,244,523 USD (9.2% revenue) in the absence of the gap.
The findings offer actionable implications for firms, platforms, and policymakers to enhance the effectiveness and appeal of sustainability programs. Firms should address consumer misperceptions by improving product descriptions. The platform can boost the CPF program’s effectiveness by increasing the visibility of CPF-labeled products and providing sellers with guidelines to better communicate sustainability attributes. Policymakers can provide support through financial incentives and educational campaigns to raise consumer demand. Only through collaborative efforts from all stakeholders can environmental programs ensure long-term success.
