CSRD (Corporate Sustainability Reporting Directive) — European directive requiring companies to produce standardised sustainability reports, including GHG emissions.

DEFRA — Department for Environment, Food & Rural Affairs (United Kingdom), publisher of emission factors used internationally.

GDPR (General Data Protection Regulation) — European regulation governing the processing of personal data; dAio Business is fully compliant.

GHG (greenhouse gases) — Gases that contribute to global warming: CO₂, methane (CH₄), nitrous oxide (N₂O), fluorinated gases.

GHG Protocol (Greenhouse Gas Protocol) — International standard for accounting and reporting greenhouse gas emissions; it defines Scopes 1, 2 and 3.

HMAC-SHA256 — Cryptographic signature algorithm that authenticates webhooks and guarantees that data originates from dAio Business.

Hotspot — Emission source identified as the most significant in your carbon footprint.

Intelligence — dAio's weather and environmental analysis layer: forecasts, risk scores and recommendations per site. See Intelligence.

ISO 14064 — International standard for quantifying, monitoring, reporting and verifying GHG emissions.

JWT (JSON Web Token) — Authentication token standard securing exchanges between client and server. See Security.

Plan — Subscription tier (Solo, Team, Enterprise) that determines your quotas and features. See Subscription.

PM2.5 / PM10 — Airborne particulate matter. PM2.5: diameter below 2.5 microns (most hazardous); PM10: diameter below 10 microns.

Quota — Limit associated with your plan: number of sites, members, credits or API calls allowed.

R2 — Cloudflare's object storage service used by dAio Business to durably store documents and reports. See Storage.

ROI (Return on Investment) — In dAio Business, measures the savings generated by weather intelligence relative to the subscription cost. See ROI.

Scope 1 — Direct emissions from sources owned or controlled by the organisation (fleet, generators, boilers). See Emissions.

Scope 2 — Indirect emissions associated with purchased energy (electricity, heat, steam).

Scope 3 — Indirect value chain emissions (supplier transport, business travel, purchases, waste). See Scope 3.

Seat — User licence in a Team or Enterprise plan; each active member occupies one seat. See Seats.

SEC Climate Disclosure — Rule of the Securities and Exchange Commission (United States) requiring listed companies to disclose their climate risks and emissions.

Site — Monitored physical location (construction site, warehouse, farm, branch office), the foundation for forecasts, alerts and emissions. See Sites.

SLA (Service Level Agreement) — Service level agreement defining the response times guaranteed by support.

Snapshot — Frozen, immutable capture of your emissions at a given point in time, forming the basis of reports and history. See Reports.

TCFD (Task Force on Climate-related Financial Disclosures) — Framework for reporting climate-related financial risks, recommended by the Financial Stability Board.

tCO₂e (tonne of CO₂ equivalent) — Standard unit for measuring GHG emissions; 1 tCO₂e = 1,000 kgCO₂e.
