Canon is collecting foreign coins, and used stamps for donation to international organizations dealing with the aid to developing countries.

The campaign to collect used plastic bottle caps has been underway since November 2009. Through the NPO Ecocap Movement, this is an activity that by collecting bottle caps "provides vaccines to children in developing countries" using the proceeds from the sale of the bottle caps, along with realizing "the promotion of the recycling of resources (resource reuse)" and "the reduction of carbon dioxide emissions."
In 2011, the Canon Group collected 1,780,000 plastic bottle caps, equivalent to 4,200 kg of caps, at ten collection points (results as of October), and donated vaccines for 2,200 people.

Canon has collected foreign coins from Canon group employees since 1996, and donated them through the Japan Committee for UNICEF to help children living under severe conditions around the world.
In 2012, foreign coins and notes estimated at 260,000yen (about 29kg) in Japanese currency were collected and donated.

Canon has collected used stamps from Canon group employees since 1994. They are sorted by in-house volunteers before being donated through Japan Overseas Christian Medical Cooperative Service (JOCS) to regions in Asia and Africa where medical care is limited. These medical cooperation projects include dispatching medical professionals.
Approximately 22kg of used stamps were collected and donated in 2012.
