Paper waste in offset printing industries contributes not only to economic inefficiencies but also to environmental
degradation through increased CO2 emissions. This study explores the integration of Lean Carbon Mapping (LCM)
with traditional Lean tools to optimize paper usage and reduce the carbon footprint associated with printing
operations. A case-based research design is applied across selected offset printing units in Tamil Nadu, India. The
methodology involves Value Stream Mapping (VSM), identification of high carbon-emitting activities, and targeted
interventions using Lean practices such as 5S, Kaizen, and Standard Working procedures. The implementation of
Lean Carbon Mapping resulted in a 45% reduction in paper waste and a 45% decrease in estimated carbon emissions
linked to material handling and print defects. The findings demonstrate the potential of LCM as a strategic tool for
advancing both operational efficiency and environmental sustainability in the printing sector.
