You may be looking at two different measurements here.

The g/L unit might refer to the maximum VOC emission per liter of paint, according to the LEED or Green Seal specification.

Green Seal certifies interior flat paints that contain a maximum of 50 grams of VOCs per liter of paint and interior non-flat paints that contain a maximum 150 grams of VOCs per liter of paint.

This Green Seal standard (GS-11) is also the baseline used by the USGBC in LEED for its point for low-emitting interior paints.


The other unit, micrograms per cubic meter, is probably more relevant here. You need to find the LEED specification for the maximum allowable VOC emission in micrograms per cubic meter.

Some documents show the following:

Total Volatile Organic Compounds (TVOC) < 500 micrograms per cubic meter

You'll need to verify it by checking the latest official specifications. Try searching on the USGBC site at:

This PDF file might have the answer you need:

Your example of 26 micrograms per cubic meter falls well within the limits, but you should check the latest specifications.
