Good Guys' Index (GGI) calculates CO2 emissions from the full casting lifecycle—raw material to customer delivery. Users can simulate and compare casting designs, methoding, foundries, energy sources, and furnaces, while calculating associated costs, energy consumption, and CO2 emissions across scenarios.
Calculates CO2 emissions of different casting processes from raw material to the transport of finished casting.
Calculates production costs of different casting processes.
GGI uses a range of data sources and algorithms to assess the sustainability of a company's supply chain.
Challenge: A defect-prone Carbon Steel casting required 4 exothermic feeders — adding unwanted CO₂.
Solution: GGI modelled a redesigned casting method, eliminating the need for extra feeders.
Result: 0.54 kg CO₂ saved per casting — a 9% reduction.
Challenge: Balance production cost, quality, and CO₂ reduction in steel casting.
Solution: GGI used to compare financial and environmental impact.
Result: Optimized feeding cut 42 kg CO₂ per part; sourcing from Turkey added up to 3,788 kg.
