Sorry, but that statement is incorrect. Natural timber itself does contain measurable levels of formaldehyde. Engineered wood and laminates do indeed contain much more formaldehyde than pure natural timbers due to the bonding agents used. Within natural timbers, hardwoods typically contain less than softwoods, but they still contain (and off-gas) measurable levels of formaldehyde. Low levels, but not no levels. See, for example, the research paper "Wood-borne formaldehyde varying with species, wood grade, and cambial age", which goes into results for various different natural species and ages. Natural hardwood is low-VOC, but not zero-VOC. For those of us dealing with extreme chemical sensitivities, the difference can be very important. Interesting article. They have measured 0.15-0.7 mg/100g which is beyond the most stringent standards (E0 is <3 mg/100g, Japanese standard is <1.2mg/100 g). Most people can't smell formaldehyde at concentrations of 0.5 mg/100g or lower. Most of the kitchens and furniture are done to E1 standard (8 mg/100 g) those days, so hardwood wooden floor won't be the worst contributor.
