Land use, land-use change and forestry (LULUCF) is a way of managing land and forests to help us manage our environment. It includes things like planting trees, using land for farming or animal grazing, and how we use forests for things like wood, paper, or other products. All of these activities affect how much carbon dioxide is in the atmosphere, which can affect the climate. By better managing our land and forests, we can help reduce the greenhouse gases that are contributing to climate change.
