Emissions of volatile organic compounds from the leaf surface back to the atmosphere under elevated [CO2] and temperature are discussed with respect to carbon losses. Furthermore, it is shown that chlorophyll contents only decrease significantly at elevated [CO2] if root growth is restricted by the amount of substrate. Early indications of influences on phenolics are given.
