Ways to Get Involved at Har HaShem

  •  Join Har HaShem's Green Team! This is a space for individuals interested in supporting environmental activities at Har HaShem and in the larger community to come together to share information, increase collaboration and momentum, and enable synergies and new activities to arise. We gather approximately quarterly; this is not a committee and there’s no formal commitment by those who choose to participate. To get involved contact Becky O'Brien at
  • Got your own environmental project that you'd like to launch at Har HaShem? Reach out to the Green Team to be supported in getting started --
  •  Attend the annual Symposium on Spirituality and the Environment
  • Have your teen participate in a climate-oriented B'Mitzvah project developed by JTree  Boulder.

Ways to Deepen Your Commitment

  • Attend Hazon's Brit Hazon program (a six-week commitment program to promote behavior change that's better for the Earth).

USA JTree is in partnership with the National Forest Foundation. For every $2 you donate, 2 trees are planted that will help remove 1 Metric ton (Mt) of carbon emission from the atmosphere over the life of those trees. 

The average American carbon footprint is 20 Mt CO2e per year. Offset your impact by planting 40 trees today.

  • JTree is an international effort, conceived following a 2019 report by Professor Tom Crowther, that shows [forest] restoration isn’t just one climate change solution, it is overwhelmingly the top one. 
  • JTree was launched at Tu B’Shevat 2020 in the UK by Rabbi Wittenberg, and in the US by Hazon and Dr. Ace Levene. Consider having your organization join this growing list of supporters. 

Please consider celebrating an upcoming Mitzvah, a new birth, or a remembrance with a JTree donation this year. 

Together, Boulder JTree has planted over 7,000 trees so far!
