In order to minimise the environmental impact of its industrial activity, Valorsul has invested in afforestation to promote the absorption of carbon dioxide emitted by the burning of waste and to offer more green areas to the population.
In line with its sustainability policy, it has committed to sponsoring environmental improvement projects in the municipalities of Amadora, Lisbon, Loures and Vila Franca de Xira. The afforestation projects in question are listed below.

These projects continued in 2011 and totalled an investment of 1 million euros, which was distributed in phases over 2008, 2009 and 2010, according to the shareholding of each municipality.
