The iron and steel industry is a strategic industry in Indonesia which is predicted to continue to grow, one of the industries whose production has been predicted to increase is the steel pipe industry. The high amount of emissions released during the steel pipe manufacturing process encourages various countries to try to reduce these emissions, one of which is by implementing the LCA method as a means of environmental evaluation. This method is also a powerful decision support tool, complementing other methods, which are equally important to help effectively and efficiently make production and consumption more sustainable. The research is conducted on steel pipe products produced by PT X using the LCA method with a gate-to-gate scope covering the subsystems of material transportation, steel pipe production, and storage and delivery as the research scope. The midpoint impact category was selected for further classification into the Global Warming Potential (GWP), Photochemical Ozone Creation Potential (POCP), Acidification Potential (AP), and Ecological Toxicity Potential (ETP) impact categories with the CML2001 and ReCiPe 2016 characterization methods. Impact potential of steel pipe production from both methods shows that the SAWH pipe produces a greater impact potential on GWP, AP, and POCP than HFW pipe. Meanwhile, ETP has a greater value on HFW pipe products. Normalization results with CML2001 normalization reference indicate GWP as the biggest potential impact on both products. The pipeline production stage contributes the most GWP with a value of 1.10E-12 per HFW and 1.82E-12 per SAWH pipe.
