/Who We Are/

Faith communities are the largest untapped force for climate action today.

People of faith have the moral imagination, the organizing infrastructure, and the shared conviction that we have a sacred obligation of care for the Earth and for the most vulnerable.

Many traditions, one cause

We believe can do much more when we when we do it together. It's going to take all of us to meet the scale of the climate crisis.

A sacred obligation to act

We help congregations green their facilities, explore their sacred traditions, and work together as a movement across the state.

/Our threefold call/

MassIPL responds to the climate crisis through the threefold call at the heart of our mission.

Pray

We ground climate action in faith, spiritual reflection, and moral imagination, resourcing individuals and congregations with materials and events that connect spirituality with the urgent needs of our climate.

Act

Our technical advising team walks with houses of worship through energy assessments, weatherization, solar, heat pumps, and electrification, unlocking millions in incentives and making buildings greener, more comfortable, and more affordable to operate.

Mobilize

We mobilize people of faith to speak with moral clarity on climate policy and environmental justice — by joining coalitions, shaping campaigns, and ensuring that historically marginalized communities share fully in the benefits of clean energy and resilience.

What others are saying

“MassIPL has been incredibly helpful to the First Church in Wenham in the ambitious ‘greening’ projects we have undertaken over the last two years: a 22.5 kw solar panel system and installing insulation in our historic sanctuary building. We are currently enjoying significant energy cost savings, reduced our carbon footprint and fulfilling our mission to care for God's creation.”
Chris Davis, First Church Wenham
“I would like to give a HUGE thank you for all of your help with our congregation's project to install solar panels. You were our guiding star! Last week's bulletin celebrated the $0 electric bills. Thank you for your commitment here at the intersection of faith and clean energy. Mass Interfaith Power and Light continues to be a voice for our climate and for the whole household of life.”
