Watershed

Watershed comes with default methodologies built by our in-house climate scientists, so your team doesn’t set up each category from scratch. Every purchase or activity is mapped automatically to the best-fit factor from 2.3 million emission factors covering 148 countries and 95% of global GDP. When your business needs a different approach, you can customize the factors and methodologies.

Sweep

Emission factor selection is AI-assisted. Teams typically configure methodology themselves, category by category.

Watershed

In minutes, AI breaks products down into editable process trees, with hotspot identification and scenario modeling to find decarbonization levers at both product and corporate level. Specialized uses it to account for recycled materials and supplier-specific energy.

Sweep

Supplier engagement is a core strength. But there’s limited AI supply chain decomposition functionality, so mapping a product’s value chain takes longer, and some calculations may need to happen outside the platform.
