Well burning most things produces CO2. Burning wood does so, too. That’s because most things we like to burn are based on Carbon (C) and burning Carbon litterallx means letting that Carbon react with Oxygen (O) from the air to make CO2.
The CO2 in wood or in gas made from crops isn’t bad for the climate tho. That’s because the plants that are burned literally sucked exactly the same amount of CO2 that is produced out of the air before because that’s how plants grow. Because of that, the total amount of CO2 in the atmosphere doesn’t rise any higher, at least if you specifically let those plants grow to burn them. On the other hand, fossil fuels are made of carbon that had been stored deep inside earths crust for millions of years, and because of that, burning them means artifically adding new co2 to the atmosphere, which will make the overall CO2 level rise, which will in turn heat up our planet.
