Abstract
Recently, the low carbon economy concept has attracted the interest of governments and enterprises. To achieve low-carbon
economy, enterprises must invest in upgrading existing facilities, processes and products so as to reduce carbon emissions.
Generally, the benefits of carbon emissions reduction of firms in a supply chain are significant, so the firms should share the
investments. Based on this idea, we studied how to coordinate the supply chain to reduce carbon emissions. Specifically, we
considered a manufacturer and a retailer which planned to invest in transforming the existing production processes so as to reduce
carbon emissions. We analyzed how the investments for low-carbon transition and the allocation of corresponding profit can affect
the behavior of the supply chain members. Optimal investment strategies both under the centralized and decentralized system are
analyzed. We have applied Nash Bargaining Game to design coordination mechanisms of supply chain systems.
