The Praxis commercial “Jaren Besparen” shows employee Theo helping his sister with simple sustainability jobs in the house, such as applying radiator foil and pipe insulation. He emphasizes that these small adjustments lead to long-term energy savings. The commercial illustrates this by speeding up time: while the sister and her family grow older, Theo remains unchanged to emphasize that the savings continue for years. The campaign, developed by Alfred International, emphasizes that sustainability can be simple and benefits both the environment and the wallet in the long term.
