Brand

The Zoru brand, and how to use it.

Logos, colours, type and voice for partners, press and anyone building with Zoru, with the rules that keep them consistent.

Logo rules

Use the official files, every time.

Do

  • Keep clear space of at least one “o” height on every side of the wordmark.
  • Keep the wordmark at least 20px tall on screen and 25mm wide in print. Below that, use the app icon.
  • Scale it from a corner, so it never stretches.
  • Use the reversed logo on dark backgrounds, and on photography only under a dark overlay.

Don’t

  • Recolour, remove or redraw the orbit ring.
  • Place the logo on the green gradient, on mid greys, or on a photo without the dark overlay.
  • Re-set “zoru” in another typeface, or add a tagline inside the clear space.
  • Add shadows, outlines, glows, rotation or stretching.

In writing, the name is Zoru: capital Z, the rest lowercase. Lowercase “zoru” appears only in the wordmark and in the domain, zoru.earth.

Colour

Green on space, green on white.

One accent, the green pair, on two grounds: deep space for the story, white and off-white for the work. Everything else is a neutral or a status colour. Body text needs a contrast of 4.5:1, and large text and interface parts need 3:1.

  • Scope colours

    The three scopes, from your own fuel and vehicles (Scope 1) to the emissions in your supply chain (Scope 3), run dark to light, so they differ in lightness as well as hue. Keep this order, and always label scopes in text too.

Typography

IBM Plex Sans speaks, Inter explains.

Headings, numbers and product titles are IBM Plex Sans, tight and confident. Body text, labels and buttons are Inter, quiet and legible. Everything is in sentence case, and there is never a third family.

  • BodyInter 400 · 16px · line height 1.65

    Describe an activity in your own words, in English, French, German or Spanish. Zoru reads it, prices it with UK government (DESNZ) factors and holds anything unclear for review rather than guessing.

  • The logo font

    The wordmark is set in Marble Bold and supplied as an image, so nobody needs the font to use the logo. Marble is for the wordmark only: headings, product names and partner names never use it.

  • Getting the fonts

    IBM Plex Sans (500, 600 and 700) and Inter (400 to 600) are open source under the SIL Open Font Licence, and free to download.

Imagery

Real forests, with the product on top.

Photography grounds the product in the world it measures. We use forest, canopy and leaf images only, and a photo always carries a product card or a facts bar. It never appears on its own.

  • Atmospheric landscapeAerial, misty and desaturated. Full width, under the dark overlay.
  • Light through the canopySaturated greens and sun flare: the hopeful register for plans and targets.
  • Texture close-upDeep greens with strong shapes, behind a card or a figure, never the whole hero.
  • NeverStock people, handshakes, wind turbines, globes in hands or smokestacks, and no AI-generated people, products or offices.

Voice

Clear, confident, practical and warm.

Zoru sounds like an expert colleague who makes carbon accounting feel doable. Lead with the outcome for the reader, then explain how, in short sentences and plain words.

  • A promise

    Just tell us. We’ll do the maths.

    Short sentences, a promise and no adjectives.

  • A feature

    Lines Zoru isn’t sure about are held for review, not guessed.

    A concrete feature with a concrete benefit.

  • The positioning

    Carbon accounting, from bills to a signed-off report.

    What Zoru does, in one line.

  • Plain, direct, checkable

    • British English, sentence case, and “you” for the reader.
    • Explain a term the first time it appears: “Scope 3 (the emissions in your supply chain)”, “tCO₂e (tonnes of CO₂ equivalent)”.
    • Every number has a source and a year. Name the factor set and its year, never “the latest factors”.
    • Only claim what the product does today.

  • House style

    • “Scope 1, 2 & 3” in headlines, “Scope 1, 2 and 3” in sentences.
    • Buttons name the outcome, such as “Get started”.
    • Plain words, no buzzwords, and no invented statistics, quotes or logos.
    • Zoru is a trading name of NOISSIME LTD. The legal name appears only in legal copy.

Co-branding

Partner first, powered by Zoru.

When Zoru sits behind a partner’s work, the partner leads. Co-branded material reads “{Partner} – powered by Zoru”, with the partner’s logo in the primary slot and the Zoru wordmark smaller.

  • The words“{Partner} – powered by Zoru”, with an en dash and a capital Z.
  • The logosThe partner’s logo first. The Zoru wordmark after it, smaller, with its own clear space and at least 20px tall.
  • ConsultanciesWhen a consultancy runs a client’s account, the client’s Carbon Reduction Plan carries the consultancy’s name, and its logo once Zoru has added it.
