The present paper discusses an EOQ model with the help of inflation for strategy of trade credit as well carbon emission under the preservation technology for deteriorating greening items. As we know, the quality of greening items day by day reduces on account of deterioration. The preservation technology is an alternative idea for the preservation of deteriorating greening items. In the present paper, the retailer supplies the green deteriorating items to the purchaser with the policy of permissible delay in payment. The buyer packs the green deteriorating items for controlling the value of green decaying items. The buyer preserves these green deteriorating items with the help of preservation technology. Some inventory costs regarding environmental issues such as carbon emission cost, packing cost, and development cost have been included. Supply chain model, preservation technology, and trade credit policy are more effective inventory tools, and recently, decision-makers are using these policies in their business policy. Flipkart, Amazon, and other online markets are using these policies and taking more profit. In the end, we have minimized the total cost with respect to inventory cycle time. Numerical example has been shown for validation of the present scenario. The observation study has been presented for the managerial insight and application in industries.
