Sonae reinforces its efforts to conserve habitats and energy efficiency through Worten's "Efficient Exchange" Campaign. In 2021, the campaign continued to promote the planting of a tree for each customer who buys A++ or A+++ equipment, as well as for any end-of-life equipment for recycling (both home collection and store delivery). As a result of the action, Worten will plant 15,000 trees, adding to the 16,000 already planted in previous years.
