	While the average ambient CO2 concentration in the atmosphere is now (2016) about 400 ppm, it can be increased to much higher levels in a greenhouse to improve plant growth.		While the average ambient CO2 concentration in the atmosphere is now (2016) about 400 ppm, it can be increased to much higher levels in a greenhouse to improve plant growth.

	The rate of CO2 consumption varies with the type of crop, light intensity, temperature, stage of development and nutrient availability. The beneficial effects on plant growth can therefore only be described in broad terms. Some reports claim a doubling or tripling of photosynthesis under certain conditions. Concentrations of 1000-1200 ppm or even up to 1500ppm are used in commercial [[greenhouse]] operations. Above this level, dangerous toxic effects to the crops and workers are more likely to occur. Other potential advantages are lower water use due to changes in plant transpiration with lower water losses. Various CO2 sources are available, such as [[biogas]] or compost which provide very clean CO2. Some [[pyrolysis]] methods (for [[biochar]] production) are also very clean and could be considered as well. However, if combustion products are present, they may be harmful to plant growth. A [[biofilter\|soil biofilter]] is a potential solution and could get rid of these contaminants.
