Have an impact while surfing the web. Green Hat is an innovative project that allows you to donate to the charity of your choice without paying a cent. Once installed, the plug-in automatically changes the advertisements on the websites you visit. As an average internet user scrolls through hundreds of ads daily, he or she can generate significant advertising revenue. GreenHat donates 51% of the profits we earn from showing the ads of our partners. You can always change the charities you donate to, customize the ads you see, or put GreenHat on pause.
