Hotel key card sustainability calculator

Compare card reuse, material input, virgin plastic and documented carbon impacts over the same year.

Sustainability comparison

Card use

Includes new and reissued cards.

Estimate from hotel activity

Environmental comparison

Current
Scenario

A reissue rate measures cards actually issued again. The scenario rate is a target; validate it against service life and operating data.

Product data & sourcesOptional

Optional. Enter measured weights, declared composition and product-specific footprints to calculate material and carbon results.

Weight & composition

Use the complete card, including its electronics, print and assembly materials. Enter a reference for each weight. Plastic share refers to the complete card. Recycled share refers only to its plastic. A material name supplies neither value.

Current
Scenario

Carbon footprint data

Use g CO₂e per finished card with comparable service, boundary, data and accounting methods. Record the source studies before comparing.

Current
Scenario

A missing value remains unassessed. Product data are supplied by you; material names do not generate emission factors.

Lifecycle context
Current

PVC body: establish the complete card composition and an accepted collection route. Electronics, coatings and bonding are part of the finished card.

Scenario

Recycled PVC: document the recycled share and its boundary. Recycled content does not establish a recycling route for a used RFID card.

Confirmed collection / end-of-life route

Record the local operator, accepted card construction and document reference. Collection alone does not confirm recycling.

Method & scope

New cards = annual issues − floor(annual issues × reissue rate / 100). Material input = new cards × finished-card mass / 1,000.

  • N = I − ⌊I × r / 100⌋
  • M = N × m / 1000
  • P = M × p / 100 × (1 − c / 100)
  • CO₂e = N × EF / 1000
N
Current new cards / Scenario new cards
I
Cards issued / year
r
Current reissue rate (%) / Scenario reissue rate (%)
m
Finished-card mass (g)
p
Plastic share of finished-card mass (%)
c
Recycled share of the plastic (%)
EF
Baseline factor (g CO₂e / card) / Alternative factor (g CO₂e / card)

⌈ ⌉ rounds up; ⌊ ⌋ rounds down. Card quantities are whole units. Percentages are entered on a 0–100 scale.

These are input-flow comparisons. Cleaning, return logistics and operating losses need separate assessment. Carbon is attributed to the year’s new-card cohort within the declared study boundary. No biogenic carbon credit is assumed.
