The Women's Institutes (WI) has made raising awareness about organ donation the focus of its new campaign.
The group is calling on all its members to make organ donation a topic of conversation with their family and friends so that loved ones do not have to deal with the burden of deciding whether to donate once they have died.
In a resolution at the National Federation of Women's Institutes (NFWI) annual meeting, which was backed by NHS organ donation director Sally Johnson, 98% of the members voted for the campaign which states that everyone needs "to make their wishes regarding organ donation known".
This will now become the focus for more than 212,000 WI members across England, Wales and the Islands.
Just 30% of the UK population is on the register and more than 80% of people say they are willing to donate organs or consider donating after their death.
Ms Johnson said: "It's wonderful that the WI has made raising awareness about organ donation their new campaign.
"The more people talk about organ donation, the more a normal part of society it will become.
"With three people dying every day in need of an organ, we need to do all we can to increase the number of organs available."
Marylyn Haines Evans, of the NFWI, said: "There is still a staggering discrepancy between the number of people requiring organs and the number of people who wish to donate organs after their death, and the best way to address this problem is through a national conversation; a heart to heart about organ donation. "
