Roberts said the Heritage Foundation’s research and advocacy has focused not on high-level, multinational agreements and conferences to tackle the issues posed by climate change but rather on smaller-scale, more community-based efforts. He said this policy position is, in part, due to the historical deference such multinational conglomerates of nations have given to China, the world’s largest emitter of greenhouse gases overall. 

He said agreements within the U.S. itself, with businesses and all levels of government working together, have produced the best results so far when it comes to improving the environment. He also pointed to examples of constructive action that don’t involve billions of dollars, such as families making the choice to spend more time outdoors or engaging in local activities that contribute to environmental conservation and community life, such as anti-litter campaigns and community gardening. The overarching goal, he said, should be to “leave God’s creation better than we found it.”

Roberts — who said he personally believes humans likely have “very little effect” on the climate — said he was discouraged to read other portions of Laudato Si’, as well as Laudate Deum, that to him read as though they had come “straight out of the U.N.” Despite his criticisms, Roberts urged his fellow Catholics to continue to pray for the Holy Father and to listen to the pope’s moral insights. 

“I just think that the proposed solutions are actually more anti-human and worse than the purported effects of climate change,” he added.  

‘A far more complex issue’

Greg Sindelar, a Catholic who serves as CEO of the Texas Public Policy Foundation (TPPF), a conservative think tank that studies the energy industry, similarly expressed concerns to CNA about the potential impact of certain climate change mitigation policies on human flourishing. 

Like Roberts, Sindelar spoke highly of certain aspects of the pope’s message while expressing reservations about some of the U.N.-esque solutions proposed in Laudate Deum. 

“I think the pope is right about our duty as Catholics to be stewards and to care for the environment. But I think what we have to understand — what we have to balance this with — is that it cannot come at the expense of depriving people of affordable and reliable energy,” Sindelar said in an interview with CNA. 

“There’s ways to be environmentally friendly without sacrificing the access that we all need to reliable and affordable energy.”

Sindelar said TPPF primarily promotes cheap, reliable access to energy as a means of promoting human flourishing. The free-market-focused group is skeptical of top-down governmental intervention, both in the form of regulation and incentives or disincentives in certain areas of the energy sector.

When asked what he thinks his fellow Catholics largely think about the issue, Sindelar said many of the Catholics he hears from express the view that government policies and interventions rarely produce effective solutions and could potentially hinder access to energy for those in need.

“I think it’s a far more complex issue than just saying we need to cut emissions, and we need to transfer away from fossil fuels, and all these other things. What we need to do is figure out and ensure ways that we are providing affordable and reliable electricity to all citizens of the world,” he reiterated. 

“When the pope speaks, when the Vatican speaks, it carries a lot of weight with Catholics around the world, [and] not just with Catholics … and I totally agree with him that we need to be thinking about the most marginalized and the poorest amongst us,” Sindelar continued. 

“[But] by going down these policy prescription paths that he’s recommending, we’re actually going to reduce their ability to have access to that,” he asserted. 

Sindelar, while disagreeing with Pope Francis’ call for an “abandonment of fossil fuels,” said he appreciates the fact that Pope Francis has spoken out about the issue of care for creation and has initiated so much public discussion.

“I think there is room for differing views and opinions on the right ways to do that,” he said.

Effective mitigation efforts 

Susan Varlamoff, a retired biologist and parishioner at St. John Neumann Catholic Church in the Atlanta area, is among those Catholics who are committed to Pope Francis’ call to care for creation and to mitigate the effects of climate change. To that end, Varlamoff in 2016 created a peer-reviewed action plan for the Archdiocese of Atlanta to help Catholics put the principles contained in Laudato Si’ into action, mainly through smaller, more personal actions that people can take to reduce their energy usage. 

The Atlanta Archdiocese’s efforts have since garnered recognition and praise, Varlamoff said, with at least 35 archdioceses now involved in an inter-diocesan network formed to exchange sustainability ideas based on the latest version of the plan from Atlanta. 

“It’s fascinating to see what everybody is doing, and it’s basically based on their talents and imaginations,” Varlamoff said, noting that a large number of young people have gotten involved with their efforts. 

As a scientist, Varlamoff told CNA it is clear to her that Pope Francis knows what he’s talking about when he lays out the dangers posed by inaction in the face of climate change. 

“He understands the science, and he’s deeply concerned … he’s got remarkable influence as a moral leader,” she said. 

“Part of what our religion asks us to do is to care for one another. We have to care for creation if we’re going to care for one another, because the earth is our natural resource system, our life support, and we cannot care for one another if we don’t have that life support.”

Responding to criticisms about the financial costs associated with certain green initiatives, Varlamoff noted that small-scale sustainable actions can actually save money. She offered the example of parishes in the Atlanta area that have drastically reduced their electric bills by installing solar panels. 

“[But,] it’s not just about saving money. It’s also about reducing fossil fuels and greenhouse gas emissions, and protecting the natural resources for future generations,” she said. 

Moreover, Varlamoff said, the moral imperative to improve the natural environment for future generations is worth the investment. “When [Catholics] give money, for example, for a social justice issue like Walking with Moms in Need or special needs, the payback is improving lives. We’re improving the environment here,” she emphasized.
