E-book reader (per book, amortized over 50 books)

E-kirjanlukija (per kirja, jaettuna 50 kirjalle)

42.1
Truecost score
Data confidence: MEDIUM

Carbon based on multiple LCA studies but device generation matters. Water and toxicity poorly documented for consumer electronics.

Environmental impact of an e-reader (e.g. Kindle) amortized over 50 books. Manufacturing produces ~168 kg CO₂e, making each book ~3.4 kg CO₂e.

Did you know? An e-reader only becomes climate-positive after reading 25+ books. The average reader reads only 12-15 books per year, so the device is worse than print for the first year.
Transparent calculation

How was this number determined?

The Truecost score is calculated from absolute physical values. Each row below shows the measured value, how it was normalized, and where it comes from.

Source data by dimension

Where do the absolute values come from?

Carbon Emissions
MEDIUM
Kindle lifecycle ~168 kg CO₂e (Cleantech Group 2009, confirmed by multiple LCA studies). Amortized over 50 books: 168 / 50 = 3.36 kg CO₂e. Includes manufacturing (~52 kg from mining alone), assembly (~10 kg), transport (~38 kg), and use-phase electricity.

  • Borggren et al. (2011): LCA of e-paper systems — Nordic Workshop on LCA
  • Achachlouei & Moberg (2015): Life cycle assessment of e-books vs paper books — Journal of Industrial Ecology

168 kg is from 2009 study on Kindle 1. Modern Kindle Paperwhite may be lower (~100-120 kg) due to efficiency gains. Range per book: 2.0-3.4 kg depending on device generation and total books read.

Water Consumption
LOW
E-reader manufacturing uses ~79 gallons (300 L) of water for mineral extraction and component production. 300 / 50 = 6.0 L per book.
  • Cleantech Group (2009): The Environmental Impact of Amazon's Kindle

Water data for electronics manufacturing is sparse. Semiconductor fabrication is water-intensive but poorly documented per consumer device.

Land Use
HIGH
Data center and factory land per device negligible when amortized per book

No significant land use per book.

Waste
MEDIUM
Kindle weighs ~200g. Only 12% of global e-waste is recycled (UN E-waste Monitor 2024). 200g / 50 books = 4g per book.
  • UN Global E-waste Monitor (2024): Electronic waste statistics

E-waste recycling rate very low. Contains lithium, cobalt, rare earths.

Toxicity
LOW
E-reader contains 12.3g lithium, 3.1g cobalt, lead solder, brominated flame retardants. Rough estimate based on e-waste DALY studies: ~300 µDALY per device / 50 books = 6 µDALY. Highly uncertain.
  • Wäger et al. (2011): Environmental and health impacts of e-waste — Environmental Impact Assessment Review

Toxicity from e-waste extremely difficult to quantify. Depends entirely on disposal method and location.

Comparisons

Methodology

Based on Cleantech Group (2009) Kindle LCA and subsequent academic studies. Device lifecycle emissions divided by 50 books (moderate reader over 3-4 year device life). Break-even vs printed books occurs at approximately 20-30 books.
