Carbon Neutral Calculators - Weddings

Here is the original list.

You can use the one for your country, and use paypal, generally. Send me any comments about your experience using these. When I'm in Canada I use Planetfair:

Planetair is managed by the Unisféra International Center, a non-profit Montreal research and consulting centre whose mission is to contribute to the advancement of sustainable development in Canada and around the world. Unisféra generates and disseminates knowledge on a broad range of sustainable development issues and offers research, consulting and training services to public and private organizations. Unisféra’s team is comprised of jurists, economists, scientists and engineers, as well as experts in management, communications, public policy, and international relations. It supports these activities by:

1) developing and funding a GHG emissions offset project portfolio, establishing an economic mechanism to achieve environmental and social objectives.
2) by certifying activities, events, and organizations as carbon neutral.

Alternative gift registries - ethical organizations

This list includes sites to register ethical donations in honor of your wedding (letting your guests give a gift to a charity or NGO in your name). See the post on Green gift registries for ecological and sustainable gifts.
