All for the environment

Our actions are proven through the quality of our cork stoppers, the partnerships we build, the figures we present and our contribution to an increasingly greener world.

A recent study by KPMG Consulting found that the carbon footprints of all M.A.SILVA stoppers analysed – NATURAL, SPARKLING and MICROAGGLOMERATEwere negative.

The findings take into account M.A.SILVA’s emissions in the different stages of the cork stopper production process and CO2 retention, to which M.A.SILVA contributes, in its cork oak forests. The analyses considered all stages of the production process, taking a cradle-to-gate approach, which included: raw material extraction, treatment, production and finishing. Subsequently, an analysis was carried out that also included the distribution phase. In addition to the already known benefits of using cork stoppers in wines, the negative carbon footprint of our cork stoppers contributes to reducing our clients’ carbon footprints.
Oenologists, winegrowers and wine specialists now have more reasons than ever to choose M.A.SILVA stoppers.

Negative Carbon Footprint

What our brand represents in the world

The carbon footprint is a measurement that expresses, in tonnes of CO2 or CO2 equivalent, the total emissions caused by a person, event, product or company. KPMG’s calculation of the carbon footprint of our cork stoppers using the Footprint Expert tool, represents the CO2 equivalent, i.e. various greenhouse gases, including methane and nitrous oxide. The fact that our cork stoppers have a negative carbon footprint means that we are contributing positively to a more sustainable planet.
