Where is the report? Which journal is the study published in?

You didn't even read the submission, did you? >IVL The Swedish Environment Institute has, on behalf of the Swedish Transport Administration and the Swedish Energy Agency, investigated the climate impact of lithium-ion batteries from a life-cycle perspective. This is Sweden, the country that has pledged to be carbon neutral by 2050.

  This is fake news. I actually read the study, and it's not even close to supporting what the author wrote.

  Tesla has pledged that the Gigafactory would be net zero: https://www.treehugger.com/renewable-energy/teslas-gigafactory-will-produce-much-renewable-energy-it-uses-net-zero-energy.html https://www.treehugger.com/renewable-energy/teslas-gigafacto... If this is accurate and comes to pass, then assuming like the Swedes did that the batteries would have 50% fossil fuel sources for production wouldn't apply.

      It's not even a third complete, I think it's a little premature to be complaining about the lack of solar panels. https://i0.wp.com/electrek.files.wordpress.com/2017/03/gigafactory-march-2017-2.jpeg?w=1400&h=&crop&quality=82&strip=all&ssl=1 https://i0.wp.com/electrek.files.wordpress.com/2017/03/gigaf... https://electrek.co/2016/07/24/tesla-gigafactory-picture-shows-construction-double-size/ https://electrek.co/2016/07/24/tesla-gigafactory-picture-sho...

The article links to the page from which you can download it.

  I read the study. It doesn't support the headline.

Here is the hyperlink to the PDF report: http://www.energimyndigheten.se/globalassets/forskning--innovation/transporter/c243-the-life-cycle-energy-consumption-and-co2-emissions-from-lithium-ion-batteries-.pdf http://www.energimyndigheten.se/globalassets/forskning--inno... I skimmed through it and didn't find where they concluded that battery production equaled 8 years of gas emmissions.

  According to the article that was a calculation made during interview. The conclusion is Tesla uses much larger batteries than needed for typical usage. You're driving back and forth to work, not across the country. Emissions grow linearly with battery size. The result is excessive but unnecessary pollution. Your range anxiety is bad for co2 emissions. If you're not just signalling and actually care about co2 emissions, you choose a car with smaller batteries.
  - greglindahl 9y ago
    And that conclusion is wrong, because a bigger battery has a longer life... the lifetime of a battery is better thought of as being a number of miles, instead of a number of years.
    - danjoc 9y ago
      A bigger battery results in greater co2 emissions. Over 17 tons in the case of a model s. 8.2 year worth. A Tesla battery has an 8 year shelf life based on Tesla's warranty coverage. Nice spin though. https://forums.tesla.com/forum/forums/battery-technology-guaranteed-8-years-then-what https://forums.tesla.com/forum/forums/battery-technology-gua...

        Here's some longevity data on real batteries: http://www.greencarreports.com/news/1110149_tesla-model-s-battery-life-what-the-data-show-so-far http://www.greencarreports.com/news/1110149_tesla-model-s-ba... As you can see, the actual lifetime is projected to be a lot more than 8 years for a typical car. Also, please don't post insults like "Nice spin" on Hacker News. Data works a lot better.
