At AG we are very careful about our impact on the wider environment and so we've calculated the carbon footprint of every product in our range. All of these figures have been carefully checked and verified. We are committed to keeping these figures as low as possible.

One of the reasons why our carbon footprint ratings are so low is because the vast majority of the aggregates we use are produced in our own quarries which are just a short distance from our manufacturing plants.
