Weathernews Climate Risk Analysis Service

Weathernews Inc. is a private weather company founded on 11 June 1986 and headquartered in Chiba, Japan, with 31 offices in 21 countries, including sales offices in Hanoi, Bangkok, Manila, Jakarta, Kuala Lumpur and Singapore. It provides weather services for shipping, aviation, roads, energy, retail, insurance and other industries, and applies its meteorological expertise to corporate climate risk.

The Climate Risk Analysis Service quantifies physical risks such as floods, storm surges, raw material procurement disruption and labour productivity loss at each site, with occurrence probabilities up to 2100, for disclosures under TCFD, ISSB, SSBJ and CSRD and for water-related TNFD analysis. A Financial Impact Analysis Service converts these results into business disruption and asset damage costs across the supply chain, and a Risk Monitoring Service links high-risk sites to daily weather forecasts and alerts through the Weathernews for business platform and weather data APIs.

• Climate risk analysis: Quantifies flood, storm surge, procurement and labour productivity risks to 2100.
• TNFD water risk: Analyses nature-related impacts from a water risk perspective.
• Financial impact analysis: Calculates losses and opportunities per site and across the supply chain.
• Risk monitoring: Turns analysis results into daily countermeasures using weather forecasts.
• Weathernews for business: Mobile and desktop weather intelligence with alerts and an AI agent.
• Weather data APIs: Forecast and observation data for analysis and system integration.

• A manufacturer with plants in northern and central Vietnam quantifies flood and storm surge probabilities per site for its ISSB-aligned report.
• A bank or leasing company analyses climate impacts on cash flows of solar farms it finances, as Sumitomo Mitsui Trust did for 130 plants in Japan.
• A logistics operator uses risk monitoring alerts to protect warehouses and staff before typhoons and heatwaves.

• Site-level probabilities of floods, storm surges and other physical risks for TCFD, ISSB and CSRD disclosures.
• Financial impact analysis with clear calculation logic for business disruption and asset damage across the supply chain.
• Moves from one-off risk assessment to daily operational countermeasures using weather forecasts and alerts.
• Backed by a weather operator with its own forecasting centres and an office in Hanoi.

Sustainability disclosure standards based on ISSB are spreading across Asia, and companies must now quantify physical climate risks at their sites and suppliers. Vietnam faces frequent typhoons, floods and heatwaves that disrupt factories and logistics, so manufacturers and lenders need both long-term risk analysis and operational weather monitoring from providers with local presence.
