Research & Collection
We gather information from multiple credible sources—scientific papers, official websites, expert interviews, and established publications. A single source is never enough to validate a claim.
Cross-Reference & Fact-Check
Information is verified against multiple independent references. We check publication dates, author credentials, and methodology. Outdated or contradicted claims are flagged for update or removal.

Common Questions About Our Sources
How do you choose which sources to trust?
We prioritize peer-reviewed research, official government data, and statements from recognized experts with relevant credentials. We avoid single-source claims and always seek independent confirmation before sharing information.
What if sources disagree?
When expert opinions differ, we present the range of perspectives and explain the disagreement. We highlight which views have broader scientific support and note when research is still evolving.
How recent must a source be?
For sustainability and environmental data, we prefer recent sources (within 3-5 years). Foundational science can be older if still valid. We flag outdated information and refresh it regularly as new research emerges.
Can I suggest a source?
Absolutely. Community members often point us toward valuable research or expert insights. We welcome suggestions—contact us at [email protected] with your recommendation.
Do you have conflicts of interest?
We sell reusable coffee cups, so we have a natural interest in sustainable beverage culture. This doesn't change our commitment to accuracy—we disclose relationships and let evidence guide our claims, not profit.
What about user reviews on your site?
Customer reviews are unfiltered real experiences. We may moderate for relevance and language but do not hide negative feedback. These honest voices help us improve and give new customers realistic expectations.
