That would be good, if it was correct. Natural gas, under complete combustion produces CO2 and water, assuming perfect 100% conversion. Basically all combustion outside of laboratory conditions are not complete.

Hydrocarbons can burn into just CO2 and water, but (using methane as an example) normally there is are intermediate steps to combustion. In a perfect combustion, the end result is 1 CH4 + 2 O2 -&gt; 2 H2O + 1 CO2. But that doesn't just occur, intermediate, lower energy steps occur producing the toxic byproducts that studies have detected in poorly ventilated gas setups. The methane might first undergo the simpler process of 1 CH4 + 1 O2 -&gt; 1 H2 + 1 H2O + 1 CO. This intermediate combustion step, if you notice, produces carbon monoxide. Very toxic. And, while under a lab condition the combustion would continue until the follow on intermediaries react the unstable CH2 into its end results, and the CO might catch a free oxygen to stabilize it, under sealed conditions. That obviously doesn't occur under real combustion. 

And that's ignoring the real toxic substance that is produced by the NG combustion, NO2. Also, rather toxic, and the major focus of the studies performed. In impure NG mixtures, with trace gases containing nitrogen, or in the high energy environment of say, an open flame, N2 making up the majority of the atmosphere can react and then form NO2, which is highly toxic. Nitrogen is inert in that it cannot itself start a flame, but it still reacts under enough energy. As the studies had shown, under poor ventilation CO and NO2 buildup can reach sub-acute levels, but still enough to pose hazards in chronic exposure. The PEL (legal limit at which point operation of a process must be halted) for workers involved with NO2 is 5ppm. Its 8hr TWA (Time Weighted Average) is just 0.2ppm, for long-term exposure over an 8hr work day.

If a recommendation is made residential building code is adjusted to require proper ventilation for gas ranges, well then honestly it seems to make sense. I don't foresee a actual ban, because there is an obvious answer to the situation in pressuring local jurisdictions to make the code changes themselves to improve the safety of people's homes after a renovation, or even before buying.

The Gas Stove copium is honestly funny af.
