GHGWatch

GHGWatch provides targeted monitoring and analytics for greenhouse gas emissions with a current focus on methane (CH4) detection across the UK. The solution ingests atmospheric and high-resolution optical/hyperspectral satellite data, together with aerial and drone measurements, to detect, quantify and attribute plume sources. Designed for energy companies, regulators and insurers, GHGWatch turns remote sensing observations into actionable inspection priorities, leak quantification and emissions-tracking workflows while highlighting likely source locations.

Key capabilities:

• Methane Plume Detection: Automated identification of methane anomalies using satellite atmospheric sensors (including Pixxel 5m hyperspectral imagery with 150+ spectral bands) and targeted high-res imagery, capable of detecting leaks as small as 25 kg/hr.
• Quantification Tools: Estimate emission rates and plume extents for prioritised investigation.
• Multi-source Fusion: Combine satellite, aerial and drone data for attribution and ground validation.
• Operational Delivery: Alerts, reports and integration for regulatory and operational teams.

GHGWatch is UK-focused and notable for combining atmospheric satellite products with high-resolution follow-up to convert detections into operational inspection tasks. It is operational with at least one of the world's major oil producers and is offered as a subscription-based information service for energy companies and the insurance/risk analysis sector.
