Update - our June Match Day was such a success that our anonymous donor has extended the 100% match for a week, through June 21! All contributions - from $10 to $1,000 - made on our website or on the Global Giving platform will be doubled!

Our gratitude to the dozens of new and long-time donors who contributed on June 13 - we have already topped the $8,000 mark! Thank you for helping us bring our engagement tools and mapping resources to more communities, spur collaboration and take advantage of advances in technology and data sharing!

This campaign began on June 8, when a team of volunteers from GoogleServe came to our office and helped us re-think our fundraising and marketing strategy. Rounding out the group were Deb Italiano from Sustainable Jersey City's Green Map team, staff and interns. It was quite helpful for all of us and we could immediately put ideas to work, especially those for our Double Match Day, June 13 (which has now become Double Match Week!) Here is part of what we developed:

Each and every local Green Map project – and there are over 800 in 65 countries – benefits from the tools, processes and icons developed by the award-winning Green Map System. This nonprofit organization has been building capacity for the participatory development of smarter, healthier and greener communities since 1995.

On Double Match Day/Week, your contributions will help this organization work smarter and support more communities, improve tools and extend collaborations, globally and locally.

On Double Match Day, June 13, we encouraged people to donate at Global Giving, where we have a project profile. More than 50 people contributed, and most were matched by the Global Giving pool of funds! A generous anonymous donor topped it up to 100%, then surprised us by offering to continue to match every donation that came in at the 100% level this week. Through June 21, all your donations from $10 to $1,000 is doubled. We are thrilled - now your support means twice as much to the Green Map network!

Now, we are encouraging donors to give directly at GreenMap.org/donate. However, the choice is yours, give directly to us or on Global Giving. Either way, it is tax deductible and matched through June 21, Summer Solstice!

Thank you for pitching in – let your friends know, using this tweet if you like:

Bridging community, economy & ecology in 65 countries, your donations to Green Map are doubled thru 6/21! http://GreenMap.org/donate

Donors of $50 or more can have their name on GreenMap.org, and all donors will be invited to the after-party, which will be announced soon.

Thank you! You can be sure this is a great way to contribute to a more sustainable and healthy future for all!
