Yes, but it's production (via plants etc.) removes CO2 from the atmosphere (in photosynthesis). So the amount of CO2 it releases is negated by the CO2 removed as the plant was growing. This is in contrast to fossil fuels, where the carbon was removed from the atmosphere millions of years ago, not in the present day.
