Cookies and similar browser-storage technologies let a site retain choices and limited state in your browser. Net Zero manages them by category: necessary storage supports the site or a feature you explicitly request; every other category is used only if you consent via the cookie banner.
Cookie categories
| Category | Purpose and cookies | Duration | Status |
|---|---|---|---|
| Strictly necessary | nz_session — session authentication; nz_consent — cookie choices; nz_auth_journey — a validated return path, language and the Save, content/topic/sector/funder Follow or Reminder action you selected; nz_linkedin_browser — a security value binding a LinkedIn sign-in request to the same browser; nz_oauth_signup — a closed, single-use LinkedIn completion token; nz_brief_access — access to the briefing pack you explicitly requested. These are first-party cookies and use httpOnly and sameSite=lax where the feature requires it. | nz_session: 30 days, renewed as you use the site; nz_consent: 12 months; nz_auth_journey: up to 24 hours, cleared after completion; nz_linkedin_browser: 10 minutes; nz_oauth_signup: up to 20 minutes, then a five-minute completion receipt; nz_brief_access: 30 days | Active — when the related feature is used |
| Functionality | netzero:timeline:v1:*, netzero:news-month:v1:* and netzero:regulation-month:v1:* local storage remember the last material-update checkpoint you saw in timelines and monthly archives | Until replaced by a newer checkpoint, functionality consent is withdrawn, or browser data is cleared | Consent-enabled — off by default |
| Performance & analytics | nz_measurement_session_v1 session storage links page views, content impressions, opens, reads, shares and outbound actions to Net Zero's first-party measurement.

To be plain: non-essential cookies and browser storage are not used until you consent via the cookie banner. Net Zero's measurement is first-party; no Google Analytics or other third-party analytics, advertising or social-media tracker is active. This page will be updated before any new provider is enabled.
Managing consent
- The cookie banner: asks for your choice on first visit, with "Accept all", "Only necessary" and per-category "Preferences".
- Cookie preferences: the "Cookie preferences" link in the footer reopens the banner, so you can change your choice at any time.
- Browser controls: you can also delete or block cookies in your browser settings. Blocking
nz_sessionmeans you cannot stay signed in; browsing without an account is unaffected. - Withdrawing consent: open "Cookie preferences" and turn a category off (or choose "Only necessary").
