For the carbonguardian.com headquarters phone number in the USA, the site publishes no phone number, no email address and no headquarters. Its footer lists two locations, Houston (USA) and The Hague (Netherlands), without a street address, and its contact route is a form on the home page.

This guide covers a lookup task: confirming who runs carbonguardian.com, then mapping a sales, partnership or procurement request to the one channel the site offers. The site is a single page with a few sub-pages, so the work is mostly knowing what is not there and what not to trust.

A Phone Number on the Site That Is Not the Company's

The team page footer shows a phone number and an email address, but they are template placeholders. The email is someone@example.com, a reserved example address, and the phone number shown on the page does not match the number in its own link. Neither is a Carbon Guardian contact, and you should not call or write to them. A page can carry stray details like this, so check that a number or address appears on the contact route of the page before you use it.

Trading Name or Legal Entity?

The pages show a brand, not a registered company. The home page gives no company suffix, no registration number and no registered office. For a contract, invoice or supplier check, ask which legal entity will sign, and check that name against the paperwork you receive. The two listed locations suggest operations in the United States and the Netherlands, but the pages do not say which entity operates in which country.

Reaching Carbon Guardian in Six Steps

  1. Confirm the domain. Use carbonguardian.com. The home page names Carbon Guardian and the C44 platform.
  2. Decide the request type. Sales, partnership and procurement all use the same published route, so the request type goes in your message.
  3. Open the contact form. It is on the home page under "Let's Get in Touch".
  4. Write a specific subject. Name the product or service, your project type and your country.
  5. Fill in the four fields. Name, email, subject and message are all the form asks for.
  6. Record the source and date. Write the page, the field and the day, and mark anything unstated as "not published".

An Example: Checking a Directory Listing

Suppose a directory lists a Carbon Guardian head office phone number in Houston. The site publishes no street address or phone for Houston, so the listing is unconfirmed. Send the contact form, state that you are verifying a listing, and ask for the correct channel. Record the answer and its date. A decision checklist: if you want to start a conversation, use the form. If a directory shows a phone number, treat it as unconfirmed. If a number comes from the team page footer, ignore it. If you need a legal entity, ask for it.

Frequently Asked Questions

What is the carbonguardian.com phone number?

The company pages publish none. A number on the team page is a template placeholder, not a Carbon Guardian contact.

Where is Carbon Guardian headquartered?

The pages do not use the word headquarters. They list two locations, Houston (USA) and The Hague (Netherlands), with no street address.

What email address does Carbon Guardian use?

None is published. The site offers a contact form on the home page, and the email on the team page is a placeholder.

Is carbonguardian.com a United States company?

It lists a Houston location in the USA and one in The Hague in the Netherlands, and names no legal entity, so the pages do not settle which country the company is based in.

Who handles sales, partnerships and procurement?

The site lists no separate teams. Use the home-page form, name the request type in the subject and ask who handles it.

How This Guide Was Built

The six steps and the route tables are this guide's own method. Each field in the fact box comes from the company's own pages, dated in the table, and a field is marked "not published" only when the pages checked do not state it. Fact, Inference and Opinion mark what a source states, what follows from it and what the author recommends. This is a November 6, 2026 snapshot.
