Passenger train products labelled as environmentally friendly now tend to be a requirement in world trade. Life Cycle Assessment (LCA) is a method for quantifying environmental performance using the Product Category Rules (PCR) document as a guideline referring to the ISO 14027 standard. This study aimed to determine the methodological requirements for the PCR draft for the Indonesian Rail-Vehicle Industry by comparing and analysing the Environmental Product Declarations (EPD) of three different rail vehicles. They were train A (from Europe) and train B and C (from non-Europe), which already had the type III ecolabel predicates, and published an EPD report referring to the PCR 2009:05 - Rolling Stock document. The result showed that each type of train had different energy consumption and environmental performance characteristics. It depends on the energy source, the weight of the material, passenger loading, and the train design speed. Train A has a carbon emission value of 0.763 grams, while trains B and C are 8.19 grams and 12.8 grams per passenger-km, respectively. The analysis of the carbon emissions in those three trains will be used as input to develop the Indonesian version of the Rail Vehicle PCR document.

Smart Contact Cards have been widely used in Indonesia, especially in the banking sector. Bank Indonesia data shows an increase in the production of Card-Based Payment Instruments (APMK) consisting of Credit Cards, Debit Cards and Debit+ATM Cards. This is also followed by an increase in transactions using APMK from year to year. The large amount of contact Smart Card waste that is disposed of every year presents a major risk of environmental pollution. This study evaluates the potential environmental impact of the contact Smart Card product based on a life cycle assessment (LCA). The input data for all elements are obtained from the literature study with Gate-to-Gate System Constraints. The assessment was carried out with the help of OpenLCA v.1.8.0 software, ELCD 3.2 database and CML (Baseline) impact assessment method. The results of the analysis show that Marine aquatic ecotoxicity is a significant potential environmental impact with a magnitude of 96%, followed by Acidification and Human Toxicity. Each contact Smart Card has 62,04526 kg1,4-DBeq in Marine Aquatic Ecotoxicity Potential, 2,22473 kgSO2eq as Acidification Potential and 0.37285 kg1,4-DBeq as Human Toxicity Potential. Further examination also shows that most of the impact comes from the choice of materials used. Copper material as the main material for the chip module plays an important role in providing environmental impact.
