Catholic Climate Covenant

There are 78 million Catholic people and 17,000 Catholic parishes in the U.S. Working together, we can fight climate change and protect the people we love.

Catholic Climate Covenant helps Catholic people and institutions respond to the moral call for action on climate change. We open policy conversation, reduce carbon footprints, and share authentic Catholic teachings on climate change. Not only do Catholics care about climate change, we have the power to overcome it. At Catholic Climate Covenant, we build relationships between people with common values and a shared commitment to protecting the people and places that we all love.

Loving our neighbors is central to our mission. Pope Francis tells us that the human family has received from the Creator a common gift: nature, and that we should be protectors of God’s gifts.

Climate change is most caused by people in the developed world and most affects people in the under-developed world. Whether it’s protecting a child in Chicago from asthma or a child in Quito from a mudslide, fighting climate change is a way to love the people God loves. We connect Catholics to live justly on God’s Earth. To download a brief summary of our work for meetings or discussions, please click here.


  • Dan Misleh

    Executive Director

    I am the founding executive director of the Catholic Climate Covenant. It's a privilege for me to wake up every day to work with our partners and supporters to share the good news of Catholic teaching on climate change and environmental protection. Before my work with the Covenant, I spent 11 years in the department of Justice, Peace and Human Development at the U.S. Conference of Catholic Bishops and three years in the Archdiocese of Cincinnati's social action office. I joined the Jesuit Volunteer Corps in 1982 where I met my wife, Susie (also a volunteer), and studied theology with the Franciscans in Berkeley, CA to obtain a masters degree. My undergraduate degree was from Xavier University in Cincinnati, my hometown. Susie and I have three children, Benjamin, Anna, and Zachary.

  • Lonnie Ellis, OFS

    Associate Director

    I started my faith-based justice vocation as part of some incredibly effective organizing in my home state of Minnesota. There I served in leadership on several successful racial justice campaigns, including securing light rail stops in communities that needed them the most. I am a lay Franciscan, and this spiritual path helps me to see people suffering from climate disruption as my sisters and brothers whom I must work to protect. I have been blessed by rich experiences along the way, including a master’s degree from Washington Theological Union, work for Franciscan Action Network, and a year in a Buddhist monastery in the Himalayas. Outside of work, I love wildlife and have seen big cats and other marvelous creatures in forests all over the world, and I play a lot of geeky strategy games.

  • Maggie McCarty, D.Min.

    Director of Development

    After more than 30 years in Church leadership, I am honored to be the Director of Development for Catholic Climate Covenant. Mine is the first generation to see the global effects of climate change, and we have to act now to ensure a healthy planet for our children and grandchildren. That's why I work here. My favorite hobby is my grandchildren. I also hike and rock climb. I love adventure travel, and have been on all seven continents. I have seen firsthand the effect of climate change. I invite everyone to do something now to care for our common home.

  • Rebecca Elliott

    Director of Communications and Engagement

    I previously directed mid-size social enterprises, and have received the Ashoka Changemaker award and given a TEDx Talk. As part of my faith-based action on climate change, I co-lead an Earth justice mission group at a beatitudes-based church and am a member of the speakers’ bureau at Greater Washington Interfaith Power and Light. I believe that climate change is the most pressing social justice issue of our time, and I have special concern for the women who are on its front lines. In my spare time, I help care for bees, chickens, and gardens at home. 

  • Paz Artaza-Regan

    Program Manager

    I have a deep passion for justice and for the protection of God's creation, and have been blessed with the opportunity to work for 17 years on environmental and human rights issues within the faith community. Originally from Chile, I see myself as a "citizen of the world" with a strong commitment to global, sustainable development. I have an M.A. in International Development from American University, and completed the course work for an M.A. in Community and Regional Planning from the University of British Columbia. Still adjusting to the empty-nest, I fill any "spare" time with tutoring, hiking, knitting, theological and political conversation, long walks with my husband and "Pepper the Pup," and cooking for friends and family. 

  • Dan DiLeo, MTS

    Project Manager

    I have managed the Covenant’s social media, newsletter and college outreach since 2009. In addition, I am the principal author of our college toolkit, and helped coordinate the publication of "Environmental Justice and Climate Change: Assessing Pope Benedict XVI's Ecological Vision for the Catholic Church in the United States." My concern for climate change comes from my commitment to Catholic Social Teaching, and I am currently earning my Ph.D. in theological ethics at Boston College. I also write for Millennial Journal and Political Theology Today.

  • Wesley Cocozello

    Executive Assistant

    I am an administrator by profession, and a writer by vocation. The journey to deeply engage with divine creation and human craft energizes all my work. I bring to the Catholic Climate Covenant multiple years of experience as a university's office manager, an arts magazine's executive editor, and an indie theater's managing director. I have spent time commercially fishing on Cape Cod, working as a creamery's newborn lamb attendant, and volunteering as a bird counter for an animal sanctuary.

  • Susan Yin

    Graphic Design Associate

    Prior to studying across the pond at University College London for my M.Sc in environmental human geography, I worked for the Chesapeake Climate Action Network as the Special Projects Coordinator, fulfilling various communications roles. As a progressive activist and self-taught artist, I hope to elevate the issue of climate change and activate the Catholic community through compelling and engaging visuals.  

  • Nelson Araque, DMin, Cand.

    Latino Outreach Manager

    I seek to raise awareness of the economic, political, social, and moral effects of climate change especially among the Church’s Spanish-speaking community. Mi ministerio es servir de enlace entre la Alianza Católica por el Clima y los Hispanos creando conciencia de los efectos económicos, políticos, sociales y morales del cambio climático sobre todo entre la comunidad  católica Hispana de los Estados Unidos.

  • Ted Miles

    Youth Outreach Manager

    I hold a BA in Psychology from Loyola College and an MA in Psychology from Bucknell University. My Jesuit influence led to a two-year Jesuit Volunteer position in education and youth ministry in Belize and Guatemala. Since then, I have obtained a professional certificate in youth ministry and has served in parish ministry, Catholic high school education and archdiocesan leadership development for the past twenty years. I have been awarded by the National Federation for Catholic Youth Ministry for leadership in youth ministry in the area of gospel values of peace and justice.
