How PGX’s Plants Reduce GHG (Greenhouse Gas) Emissions

Each hectare of polygenomic plants uses an average 100 tonnes more CO2 each year than the equivalent area of standard (diploid) plants.  Accordingly, we estimate that 10 million hectares of our plants will use 1 billion tonnes EXTRA CO2 every year.

If those plants are used for renewable energy, they prevent the release of a TOTAL 6 billion tonnes of “old fossil fuel carbon” into our atmosphere, or 1 billion tonnes MORE than can be hoped from the next best currently available renewable feed stocks.


Most plants grow by cycling CO2 into their leaves where sunlight powers chemical reactions that crack the CO2 into Carbon (which becomes plant sugars, the basic building blocks for all growth) and Oxygen (which is expelled as waste).

Standard plants are not 100% “carbon efficient”. One cycle in three or four they expend energy but fail to crack a CO2 molecule.  These energy-wasting cycles are called “photo-respiration”.

Our plants all but eliminate photo-respiration and so use up to 50% more atmospheric carbon for the same expenditure of time, energy, water and nutrients, accelerating growth and so using more-on-more carbon.

Faster-growing stress-tolerant disease-resistant plants which yield more in less time for no increase in inputs are more profitable and so many agricultural and silvicultural enterprises will progressively adopt polygenomic plants as their standard.

As fields and forests transition to our plants, more and more CO2 will be drawn from the atmosphere and locked into plant growth while more oxygen and moisture will be recycled into the atmosphere.
