RELEX Solutions – Purpose-Built for Sustainable Forecasting

RELEX Solutions’ platform is engineered to reduce waste and optimize freshness. Their demand forecasting is not just accurate but it’s shelf-life aware, ensuring that replenishment aligns with product perishability, sales velocity, and spoilage risk. Their replenishment engine automates stock movements in real-time, continuously recalibrating based on freshness windows and demand variability. Beyond waste reduction, RELEX has developed in-platform tools for CO₂ emissions visibility, giving planners the ability to evaluate sourcing and inventory decisions through a sustainability lens.

 

Retailers can model sourcing and fulfillment scenarios based on their carbon footprint, enabling decisions that balance commercial performance with environmental impact. Additionally, RELEX minimizes unnecessary transfers and emergency shipments, two often-overlooked contributors to Scope 3 emissions by optimizing inventory flows across the supply chain.

o9 Solutions – ESG Strategy Meets Forecasting Intelligence

o9 Solutions offers a combination of planning sophistication and sustainability modeling. The platform integrates real-time ESG metrics across the forecasting and supply planning process. Retailers can simulate replenishment scenarios that balance cost, service levels, and emissions enabling truly informed, environmentally conscious decisions.At its core, o9 enables planners to embed sustainability KPIs directly into operational decisions, whether that means evaluating carbon emissions by sourcing region or optimizing for energy usage across the supply chain. This level of granularity supports both compliance and strategic ESG planning, making it a standout for global, enterprise-scale retailers.What sets o9 apart is the tight integration of sustainability with profitability, planning decisions can be evaluated through both a commercial and climate impact lens.

SymphonyAI – Replenishment Automation that Avoids Excess

SymphonyAI focuses on automation-driven supply chain efficiency. Through AI-powered forecasting, allocation, and replenishment, the platform helps retailers reduce inventory imbalances and avoid unnecessary transfers or stockouts. This directly contributes to lowering environmental impact by cutting down on excess transport and stockholding.While not designed around shelf-life modeling or ESG dashboards, SymphonyAI's intelligent replenishment logic helps optimize the flow of goods across channels and nodes. Retailers benefit from more accurate inventory positioning and fewer emergency restocks, two often-overlooked drivers of retail emissions and waste.

Aptos – Lifecycle-Driven Efficiency That Reduces Waste

Aptos brings sustainability into the operational fold through its product lifecycle-driven planning. The forecasting and replenishment logic of the platform is designed to align inventory flow with product seasonality and will help retailers not be stuck with end-of-life overstocks and unneeded markdowns. Aptos' strength includes managing both new and aging products across multiple seasons while using real-time demand sensing and replenishment adjustments. Although the platform is missing emissions tracking or ESG analytics, it does contribute to sustainability. It can help retailers keep their inventory performance lean across the entire product lifecycle.

Solvoyo – Flexible Architecture, but Sustainability Requires Customization

Solvoyo Offers an AI-enabled replenishment platform plus convenience in supply chain flows, Solvoyo performs well in high-velocity and fresh product environments. The platform readily accommodates modeling in terms of freshness constraints and expiration timelines and is useful for managing sustainability-influenced operations in grocery and perishables. The platform does not currently have embedded ESG analytics or standardized emissions tracking tools, for example. Sustainability-focused capabilities include user-defined features that consider scenario modeling for the sourcing of products or the routes used for fulfillment.

Consequently, the extent Solvoyo contributes to sustainability outcomes is dependent on how the retailer customizes and implements the platform. The capability for flexibility is a benefit for customized planning - retailers considering sustainability should understand that, if they want out-of-the-box sustainability in their decision-making, Solvoyo will require some work.

Retalon – Forecasting Strength, but Limited Sustainability Features

Retalon delivers strong performance in core retail planning areas such as demand forecasting, allocation, and replenishment, all unified through a single AI engine. This enables retailers to reduce overstocking, avoid excess inventory, and improve overall planning efficiency. However, the platform currently lacks explicit support for sustainability metrics. It does not model shelf-life constraints, offer emissions tracking, or provide tools for ESG scenario planning. While Retalon does not currently offer standalone emissions tracking or ESG scenario modules out of the box, its advanced planning engine lays a strong foundation for sustainable operations.

Sustainable Retail Begins at the Planning Table

Sustainability isn’t just a marketing goal or compliance requirement but it’s an operational lever. From emissions to spoilage to markdowns, the environmental cost of poor forecasting is measurable and avoidable.

Retailers serious about sustainability need platforms that:

• Plan with shelf-life and expiry in mind
• Simulate emissions trade-offs and sourcing routes
• Reduce inventory bloat through real-time replenishment
• Enable scenario planning that balances profit and planet

These aren’t bonus features. They are must-have capabilities in retail.
