Dopper is a Dutch company trying to change the ocean and Nepal's water with one reusable bottle that ends single-use plastic. It began in 2009, when founder Merijn Everaarts was shaken by a documentary about albatrosses dying from ocean plastic. Its three-part design integrates bottle and cup to encourage drinking tap water and cutting single-use. Its B Corp score of 132.8 puts it in the world's top 10%, and it is “Best for the World” for environment (top 5% of companies with 10–49 employees). Carbon-neutral since 2022, all its products are Cradle to Cradle certified, and the Dopper Original is the world's first C2C Gold bottle collection. The Dopper Foundation (2013) devotes 5% of net sales to water, sanitation, and education — with a special focus on Nepal. Partnering with the Dutch NGO Simavi and the Kathmandu social enterprise SmartPaani, it has built hundreds of water points and toilets and delivered safe drinking water to roughly 93,000–130,000 Nepalis to date. “Dopper Wave,” launched in 2020, is a movement to quit single-use bottles, with over 7,000 people and over 900 organizations pledging. Across all users it estimates 99 million kg of plastic saved from the ocean.

Dopper: One reusable bottle — for the ocean, and for Nepal's water. The letter is B; certainty is medium. Unconfirmed concerns are placed under “Watching.” (As of 2026-Q2; estimate based on public information.)
Main narrative
One person’s story (N1)
+ before → after
Nepal, where many lack safe drinking water despite sitting right beside great freshwater reservoirs. For every bottle sold, Dopper partners with the Dutch NGO Simavi (water, sanitation, and equal opportunity for women and girls) and Kathmandu's SmartPaani to build water points and toilets in villages. Over 15 years it has delivered safe drinking water to roughly 93,000–130,000 people and spread sanitation education. One bottle that ends single-use in the sea also reaches a tap in a distant village. Source nature: company disclosure plus NGO partnership (with B Corp and Cradle to Cradle as independent backing).

− effects (confirmed)
- No confirmed −.
- Independent verification of the Nepal benefit
- Supply chain (under BSCI) from manufacturing non-Original products in China
- Basis for the ocean-plastic-saved estimate
- Growing Dopper Wave, deepening recycling and circular design, and continuing water, sanitation, and education in Nepal (the Water & Waste Academy).
A second look
The core + is cutting single-use and ocean plastic (nature) and water access in Nepal (people), strongly backed by B Corp (132.8, Best for the World), Cradle to Cradle Gold, and independent design awards. That said, the Nepal benefit is a ripple form via an NGO, and reach numbers rest mainly on the company's and partners' tallies. Products other than the Original are made in China under the BSCI code of conduct, so the supply chain merits watching.

How to read this assessment
- Reachable upper bound (ceiling): a confirmed − sets the ceiling, and independently verified + decide the position within it. + do not cancel out −.
- The weight of evidence is not symmetric: only confirmed − are counted; the volume of disputes or allegations goes under “Watching.” + are counted from independent evidence, while an organization’s own PR is treated as “reference.”
- Size is not value: scale is not used in the assessment. Matters that stay within money or competition—investors, shareholders, sanctions, trade secrets—are also excluded.
- The letter (assessment) and certainty (how reliable the information is) are separate axes.
This is a translation; the Japanese version is authoritative. The assessments here are generated automatically by AI based on published criteria. The operator does not alter individual results. Because they are AI-generated they may contain errors, and they are opinion and commentary, not statements of fact. Where evidence is insufficient, the entry is marked “On hold.” Requests for correction are accepted via the form.
Terms: Narrative Value = an assessment (A–G) of the distance between the story an organization tells and its reality / Ceiling meter = a visualization of the reachable upper bound / Watching = unconfirmed matters not counted / Protected stakeholders = people, animals, nature, and future generations. | Generated by: AI | As of: 2026-Q2 | Back to top
