Cloud carbon, made of grid intelligence

Measure what your cloud infrastructure actually emits. Reduce where it actually counts.
Ambra turns Nodera's hourly, datacenter-level grid intensity into resource-level cloud emissions, and the recommendations that cut carbon and cost together.

What's broken

Carbon accounting arrive months after carbon was emitted. National averages smooth the signal flat. Annual reporting cadence buries the only volatility that matters: the hour-by-hour electricity mix that actually powered your workload.

What Ambra changes

Ambra ties every cloud resource to the actual mix that powered it, at the datacenter, at the hour. Carbon and cost become two faces of the same decision, and both become actionable.

The Ambra suite

Spectrum measures cloud emissions at the resource level. Delta turns that signal into the recommendations that cut carbon and cost. Both are powered by Nodera's hourly, datacenter-level grid intensity. No second data pipeline, no second source of truth.

Coverage

Exactly what Ambra reads, and how it reads it.

Clouds and resources

One connector per resource category, each pulling real usage from the cloud's own monitoring API. AWS and GCP today, across the categories that drive the majority of cloud emissions.

Compute
Storage
Databases
Network
Managed services

Mapped to the datacenter, not the country.

Every AWS and GCP region is mapped to the physical datacenter that powers it. When a region spans multiple sites, Ambra averages the local hourly intensity of each, weighted by capacity. Workloads inherit the grid signal of where they actually ran, not a national disclosure.

From cloud usage to carbon, in three steps.

Ambra reads what each cloud resource actually used, converts that usage into energy with research-backed coefficients, then multiplies the result by Nodera's hourly, datacenter-level grid intensity. Every step is auditable; every output cites its inputs.

Real usage from your cloud

Spectrum reads usage metrics straight from your AWS and GCP accounts through read-only API connectors. Every figure traces back to a resource the cloud provider actually billed: vCPU-hours, GB-stored, GB-transferred, requests.

Energy from usage

Each unit of usage is converted into Watt-hours with research-backed coefficients: SPECpower data for compute, manufacturer datasheets for storage and networking. Coefficients are public and versioned, so every figure can be reproduced.

Carbon from energy

Nodera multiplies Watt-hours by its hourly, datacenter-level grid intensity, computed from grid topology, local generation, weather, and demand. Every cloud region maps to the datacenter that physically powers it, so workloads inherit the local grid signal, not a country average.

How you receive Ambra

Two surfaces, one signal. The report for reporting, the API for everything else.

Audit-ready report
Sustainability

A branded PDF and Excel package, delivered monthly, quarterly, or annually. Resource-level Scope 3 cloud emissions, methodology note, ESRS E1 and BEGES crosswalk, and Delta's ranked recommendations.

REST API
GREENOPS

A stable, versioned API for every Spectrum and Delta output. Authenticated by API key, with an OpenAPI spec for any language. Plugs into the cloud usage and billing exports already in your account, no new agents.

Who Ambra is for

Built for the teams cloud emissions actually touch.

Sustainability & ESG

Cloud emissions your auditor can sign off.

CSRD and BEGES now expect the granularity Ambra produces by default: hourly, location-based, traceable to the resource. Reports come out of Spectrum with the methodology already documented.

GreenOps & Platform Engineers

Carbon as an engineering metric.

Hourly, resource-level emissions wired into the same tools your team already uses. Delta turns the signal into a ranked backlog of optimizations, not a dashboard your team has to interpret on its own.

Cloud Finance / FinOps

One signal. Carbon and cost.

Spectrum and Delta compute emissions and savings from the same usage and pricing data. The trade-off conversation between sustainability and spend happens once, with both numbers on the table.
