  "description": "Packaging redesign projects — thinner corrugate, right-sizing boxes, switching to mono-material film — save money on material cost and on freight, since lighter and smaller packages cost less to ship, and they cut embodied carbon because less material is manufactured and transported. This calculator compares your current packaging weight and unit volume against a redesigned version, computing material cost savings, an estimated freight savings from reduced dimensional weight, and the emissions avoided from lower material throughput. Companies use this to build the business case for packaging engineering investment, since procurement and sustainability teams often need both a cost number and a carbon number to get sign-off. A 20% weight reduction on a high-volume SKU can add up to six figures annually once you multiply by shipping volume, which is usually the number that gets a redesign project funded.",
  "formula": "Material savings = units × (old weight − new weight) × cost per lb. Freight savings = units × freight savings per package. Emissions avoided = units × weight reduction × material emission factor.",

    {
      "q": "Why include freight savings, not just material cost?",
      "a": "Parcel carriers price on dimensional weight above a threshold, so a lighter, smaller package can drop a shipment into a cheaper rate tier even when the material cost difference is small. For high-volume e-commerce SKUs, freight savings from right-sizing often exceed the material savings alone."
    },
    {
      "q": "What material emission factor should I use?",
      "a": "Corrugate cardboard runs roughly 0.9-1.1 kg CO2e per lb depending on recycled content; virgin plastics run higher, often 1.5-3 kg CO2e per lb. Use your specific supplier's environmental product declaration (EPD) if you have one — generic factors are fine for a directional estimate but not for public claims."

    {
      "q": "How long do packaging redesign projects typically take to pay back?",
      "a": "Tooling and validation testing (drop tests, compression tests, transit testing) usually take 3-6 months, and most redesigns pay back the tooling investment within the first year once you're at meaningful volume, since the per-unit savings compound with every shipment."
