Klimaneutrales Unternehmen
Jedes Unternehmen verursacht CO2-Emissionen, ganz gleich, wie nachhaltig und sparsam es wirtschaftet. Klimaschutz bedeutet, alle Emissionen zu erfassen, um sie dann kontinuierlich zu reduzieren und zu vermeiden. Konsequent ist, wer alle unvermeidbaren Emissionen über ein Klimaschutzprojekt ausgleicht.
Seit kurzem sind wir ein offiziell zertifiziertes klimaneutrales Unternehmen. Als Großhandel für Solar, Montage- und Speichersysteme unterstützen wir ein Klimaschutzprojekt, welches uns sehr am Herzen liegt: Unsere CO2-Emissionen gleichen wir durch effiziente Kochöfen in Ghana aus.
