    2026 Green Industry Outlook

    The key points for 2026 are: 2025 was a good year for many green industry firms as there was strong demand in many parts of the state; there are many unknowns going into 2026 that will impact green industry sales: mixed signals within the economy, increased input costs, and in particular the varying strength of the housing market in Georgia will play a major role; green industry demand is expected to slow, with prices expected to decrease to offset the decreased demand, which will result in decreased sales in 2026 compared to 2025.
