How can we decline our carbon footprint on construction sites?

The term carbon footprint refers to how much greenhouse gases (GHGs) are being released into the environment when using or manufacturing a product or performing an activity. The major contributors to a project’s carbon footprint are its fuel use, electricity use, and the amount of debris that goes into the landfill. Which steps can we take to reduce these factors and so to lower the carbon footprint of a building project.
