Catholics and Climate Change

Speculation to Advocacy: Reducing Carbon Pollution

In advance of a community conversation at the University of Massachusetts Catholic Newman Center on Saturday, October 4, 2014 from 2:00pm –  4:00pm, this article is being shared to help us think about “what would Francis do” about climate change?

In his Summa Theologiae, Thomas Aquinas distinguishes between two facets of human intellect: “speculative intellect which directs what it apprehends, not to operation, but to the consideration of truth; while the practical intellect is that which directs what it apprehends to operation” (I, q. 79, a. 11). Although each aspect has unique characteristics, Aquinas insists that the speculative and the practical “are not distinct powers” but together constitute the fullness of human intellect (I, q. 79, a. 11, s.c.). In other words, speculation and application are two sides of the same coin.

For political theologians, it is often a challenge to translate abstract speculation into concrete political advocacy. Although there are likely many reasons for this reality, it is a situation with which we should not be satisfied. It is always necessary, therefore, to identify and take action in situations where a direct connection between the speculative and the practical exists. One such opportunity arose earlier this summer with respect to climate change mitigation, and political theologians should now advocate around the proposed policy.

carbonClean Power Plan and U.S. Catholic Bishops

On June 2, 2014, the U.S. Environmental Protection Agency (EPA) proposed the Clean Power Plan by which to reduce carbon pollution from existing power plants. The EPA is accepting public comments about the Plan until mid-October, and Republicans in Congress are working to block, interfere with, and/or otherwise eviscerate the Agency’s proposed carbon pollution standards.

The Catholic Church has explicitly and repeatedly recognized climate change as a moral issue that threatens to compromise the commitments of Catholic Social Teaching (to learn more, visit the Catholic Climate Covenant). As such, the Church continues to call on persons of faith and goodwill to address this issue through both individual efforts and coordinated public policies.

Shortly before the release of the Clean Power Plan, Archbishop Thomas Wenski of Miami wrote a letter to the Environmental Protection Agency on behalf of the United States Conference of Catholic Bishops (USCCB) as chair of its Committee on Domestic Justice and Human Development. There, the Archbishop highlighted the USCCB’s awareness that “the best evidence indicates that power plants are the largest stationary source of carbon emissions in the United States, and a major contributor to climate change” (indeed, carbon dioxide is the most pervasive greenhouse gas, and fossil fuel power plants—which account for 38% of U.S. carbon pollution—are the largest collective domestic source of this pollution).

In light of this reality, Archbishop Wenski emphasized that “the USCCB recognizes the importance of finding means to reduce carbon pollution.” Towards this end, the Archbishop insisted that carbon pollution standards be guided by key aspects of Catholic teaching: “Respect for Human Life and Dignity, Prudence on Behalf of the Common Good, Priority for the Poor and Vulnerable, Social and Economic Justice, Care for Creation and Participation.”

On July 30, 2014, Archbishop Wenski followed this initial letter to the EPA with another that he co-authored with Bishop Richard E. Pates of Des Moines, Chair of the USCCB Committee on International Justice and Peace. There, the two bishops declared: “We … welcome the setting of standards to reduce carbon pollution from existing power plants and thereby mitigate climate change. We support a national standard to reduce carbon pollution and recognize the important flexibility given to states in determining how best to meet these goals.” Towards this end, the bishops reiterated the ethical criteria for carbon pollution standards that the USCCB articulated in its May letter to the EPA. Finally, the bishops “call[ed] upon our leaders in government and industry to act responsibly, justly and rapidly to implement such a [national carbon pollution] standard.”

Catholic Advocacy around Carbon Pollution Standards

In light of the Clean Power Plan and the Catholic bishops’ advocacy around a national carbon pollution standard for existing power plants, political theologians have a distinct opportunity to practically engage in an active policy debate. Although their contributions to the discussion might take several forms, there are two immediate steps that political theologians are able to take. First, political theologians can submit faith-based public comments to the EPA. In addition, political theologians can contact their elected officials and urge them to support a national carbon pollution standard for existing power plants that is animated by Catholic teaching.


In his 1990 World Day of Peace Message, St. John Paul II recognized that “the ecological crisis is a moral issue” (emphasis in original). Guided by this awareness, Pope Emeritus Benedict XVI asserted in his encyclical Caritas in veritate that “the Church has a responsibility towards creation and she must assert this responsibility in the public sphere” (# 51). The current debate around the Clean Power Plan is a unique opportunity within which to bring Christian theology to bear on an active policy debate. As such, I urge political theologians to, at the very least, submit faith-based comments about the proposal to the EPA and let their elected officials know that they support a national carbon pollution standard guided by Catholic teaching.
