Pope Leo XIV has called for pressure to be placed on governments to protect the environment as he stressed that damaging the natural world is incompatible with the Christian faith in a speech at a climate conference Wednesday.
“We cannot love God, whom we cannot see, while despising his creatures,” Leo told the conference which was held to mark 10 years since Pope Francis’ landmark document on the environment. “Everyone in society, through non-governmental organizations and advocacy groups, must put pressure on governments to develop and implement more rigorous regulations, procedures and controls.”
The American pontiff’s remarks came in his first major speech on the environment since his election in May. Leo has indicated he wants to continue with his predecessor’s efforts to tackle the climate crisis, opening a new ecological center in the papal summer residence of Castel Gandolfo, about 15 miles outside of Rome, and calling for the conversion of people “inside and outside the church” who don’t recognize “the urgent need to care for our common home.”

The sustainable construction sector is moving from aspiration to measurable transformation driven by both market momentum and policy alignment. Global agreements on fossil‑fuel phase‑downs are accelerating the shift towards low carbon design and net zero carbon buildings, prompting deeper integration of whole life carbon assessment and lifecycle assessment into sustainable building design. Kenya’s focus on refining critical minerals domestically signals a new model for renewable building materials and low carbon construction materials that support the circular economy in construction.
In the UK, rising energy prices have created unprecedented demand for energy-efficient buildings, heat pumps, and solar technologies. Retrofit strategies are becoming central to sustainable building practices, emphasising embodied carbon reduction across heritage and modern assets. By applying eco-design for buildings and whole life carbon evaluation, developers are aligning life cycle cost analysis with environmental sustainability in construction, showing that character preservation can coexist with high performance in sustainable architecture.
Data innovation is reshaping carbon accountability. The UK Space Agency’s deployment of AI-driven forestry monitoring introduces a step change for carbon footprint reduction and more precise reporting through environmental product declarations (EPDs). These advances enable stronger correlation between embodied carbon in materials and the environmental impact of construction, reinforcing the need for transparent metrics across the building lifecycle performance framework and sustainable material specification.
The threat of policy weakening, potentially costing hundreds of thousands of green construction jobs, underscores the fragility of progress towards net zero whole life carbon and carbon neutral construction. Yet from Africa to Europe, decarbonising the built environment has become the cornerstone of sustainable urban development. The construction industry is embedding low embodied carbon materials and circular construction strategies into its core, signalling that eco-friendly construction is not a niche trend but the foundation of the next generation of green infrastructure.
