  Thanks. It appears that the sequestration credit for vertical farming presumes that agricultural land formerly used for lettuce will be converted to a forest. That's questionable but not crazy. It gets worse when you look at the footnotes. They assume that the electricity going to the vertical farm is produced at the Swedish average carbon intensity per kWh. Sweden is far below the OECD average for electrical energy carbon intensity: http://www.compareyourcountry.org/climate-policies?cr=oecd&lg=en&page=2 http://www.compareyourcountry.org/climate-policies?cr=oecd&l... Only Switzerland, Sweden, Iceland, and Norway have low enough electrical carbon intensities for vertical farming to have a smaller carbon footprint, even conceding the re-forestation assumption.
