We build custom climate tech software because off-the-shelf sustainability tools hit a wall. They can't ingest your sensor data, map it to GHG Protocol Scope 1, 2 and 3 categories, or flex around SECR and CSRD reporting requirements.

Talk to us about your project

Manual workarounds pile up. Data sits in silos. Compliance risk grows quietly until audit season forces a scramble. Custom software connects your sources, models your workflows and creates a single auditable source of truth. We scope the problem in discovery, then build a platform that scales with your operations.

That means proper sensor integration, automated emissions calculations and reporting formats your auditors actually accept. No stitching spreadsheets together. No outgrowing a vendor's roadmap. When we built Elecsys, a platform for managing electricity network assets in the renewables sector, we solved exactly this kind of sensor-to-dashboard integration challenge. If your climate data lives in five different places and your team spends days reconciling it, custom software closes that gap permanently.

Which climate tech projects need custom software?

Off-the-shelf tools fall short when your data sources, workflows or reporting obligations are unique. These four project types consistently benefit from a ground-up build.

  • Energy

    Renewable Energy Management

    Grid operators and energy firms need platforms that ingest live generation data, forecast output and balance supply across sites with different hardware, tariff structures and grid connection rules. Generic dashboards can't handle that level of site-specific logic, let alone the regulatory reporting these organisations face.

  • Emissions

    Carbon Accounting Tools

    Scope 1, 2 and 3 reporting demands auditable data pipelines mapped to GHG Protocol categories. A purpose-built platform automates factor calculations and produces regulator-ready exports.

  • IoT & Sensors

    Sensor Data Dashboards

    Environmental monitors, smart metres and field sensors generate time-series data at volume. That data needs secure ingestion, buffering for patchy connectivity, clear visualisation for operations teams and retention policies that satisfy compliance.

What Your Climate Platform Must Do

Regulators and internal teams both need the same core capabilities: automatic data ingestion, GHG Protocol (Greenhouse Gas Protocol) mapping, auditable versioned reports and real-time alerts. They want a compliance-grade system they can trust, not a pretty dashboard.

  • Automated sensor and metre ingestion
  • Scope 1, 2 and 3 emissions mapping
  • Versioned, audit-ready regulatory reports
  • Real-time monitoring with threshold alerts

Platform Capabilities We Build

We build climate platforms that connect sensors, reporting, forecasting, compliance and scale.

Discovery First, Then We Build

Most climate tech projects start with unknown integrations, reporting rules and workflows that only exist on a whiteboard. We run an in-person discovery phase from our London or Belfast office to lock scope, milestones and a realistic budget before we write a line of code.

  • Senior in-house UK team, not outsourced
  • Locked scope before development starts
  • Predictable budget with milestone sign-offs
  • Faster route to a working product

How does a climate tech software project work?

Every climate tech engagement follows the same transparent, phased structure. You see progress at every stage.

  1. Briefing and scoping call

    We meet in person or over video to understand your problem, data sources and reporting needs. You leave with a clear outline of what discovery will cover.

  2. Discovery sprint

    Our team researches your domain, maps architecture and locks scope into defined milestones with acceptance criteria. No code starts until you sign off the plan.

  3. Design and prototype

    We build interactive prototypes you can test with real users. This validates the concept before committing to a full build.

  4. Milestone-driven build

    Development runs in short sprints. At each milestone you get a working demo, review it against acceptance criteria and approve before we move on. No waiting months for a single handover.

  5. Testing, compliance and launch

    We run thorough QA and check regulatory and data requirements. Then we deploy to production so your platform works on day one.

  6. Ongoing support and iteration

    After launch we stay with you, monitoring performance and fixing issues. We build new features as your reporting needs or user base grows.

How do you choose a climate tech software partner?

The wrong partner costs you months and credibility. Before you sign, confirm the team you meet is the same team that builds your platform. Green flags: a structured discovery phase before any code, milestone delivery with clear sign-off points, and genuine understanding of environmental data workflows. Red flags: offshore handoffs after the sales call, no scoping phase, and vague timelines with nothing concrete behind them.

We run in-house engineering from our London and Belfast offices, prototype before committing to a full build, and lock scope so you can review progress at every stage.

  • In-house team builds your product
  • Discovery phase before any code
  • Milestone delivery with clear sign-off
  • Sector knowledge of environmental data

Are we the right fit?

We're honest about where we add value. Here's how to tell if we're the right partner for your climate tech project.

A great fit

  • You need custom software because off-the-shelf tools can't handle your data sources or workflows
  • You have complex integrations like sensors, metres or third-party environmental datasets
  • You face regulatory reporting requirements such as GHG Protocol or Scope-based emissions disclosures
  • You want a senior, in-house UK team building your product, not offshore juniors
  • You're ready to invest in a proper discovery phase before writing code

Not the right fit

  • You need a simple brochure website or basic WordPress site
  • You're looking for the cheapest possible option rather than the right one
  • You have no budget or willingness to run a discovery phase first
  • You want to skip scoping and jump straight into development without a plan
  • You need a rebrand or marketing campaign rather than a software product

FAQ

Climate tech software FAQs

What is Myth’s approach to climate tech software?

Our agile methodology and collaborative design thinking ensure responsive and adaptable software development. We deeply understand the climate tech sector and offer modular, scalable solutions tailored to your needs. We also use cutting-edge technologies like edge computing and sustainability analytics and deliver innovative tools that drive measurable environmental and commercial impact.

How do platforms measure and report emissions?

Platforms ingest data from metres, sensors and invoices, then map it to Scope 1, 2 and 3 categories and apply emissions factors. We build in automated validation and versioned exports compatible with regulators.

Do climate-tech platforms need AI?

Not always. AI adds clear value for demand forecasting, anomaly detection on sensor streams and predictive maintenance. We typically recommend starting with deterministic tracking, then layering in models where they reduce cost or risk.

Can platforms integrate IoT sensors and metres?

Yes. We use secure device provisioning, time-series data ingestion and buffering for unreliable connectivity. Data flows to the cloud for processing, with configurable rules for retention and latency.

How long does it take?

This is a lightweight audit. We keep it to 30 minutes, which is more than enough time to have a look and give you some suggestions and a mini-report.

What emissions standards should my platform support?

Most platforms need GHG Protocol and Scope 1, 2 and 3 categorisation at minimum. ISO 14064 matters if you need third-party verification. We configure reporting logic to match the standards your auditors require.

How is energy data kept secure?

We implement role-based access, audit trails and encryption in transit and at rest. Hosting on UK Azure infrastructure meets data-residency needs. We also build to support GDPR compliance for any personal telemetry data.
