How does construction pollute?
During construction, activities such as grading and demolition create pollutants that can leave the site and harm our waterways. Sediment is one of the main pollutants of concern. When it rains, stormwater washes over the loose soil on a construction site, along with various materials and products being stored outside.
What are the environmental risks of construction?
It is no surprise, one of those most environmentally damaging side effects of construction is waste production, with construction and demolition waste contributing to 40% of landfill waste. Having a waste management strategy in place to minimise this, is an important way to reduce construction environmental impacts.

Is construction a big polluter?
As an industry, it's responsible for almost a quarter (23%) of all air pollution on the planet. But besides emitting a variety of different contaminants into the air, construction also damages the planet in other ways, too.
How does construction pollute the land?
