Ricardo Teixeira has spent the past few weeks freshening up Love Lomas, the "love motel" he owns in the Brazilian port city of Belém.
He's also mulling how to tone down some of the rooms' more sensual aspects, including erotic chairs and menus of sex toys for sale. It's all in anticipation of welcoming a very different type of guest than his usual clientele.
Love motels are common throughout Brazil, with rooms available by the hour often booked for romantic trysts. But as tens of thousands of people descend on Belém for COP30 — the world's biggest annual climate summit — a dearth of accommodation has led to a scramble for beds.
The prospect of diplomats, scientists and climate activists being asked to specify which erotic features they'd like removed from rooms is striking, but it also speaks to a serious issue.
"Their voices (will be) silenced in the very rooms where decisions about their survival are being made," said Harjeet Singh, a COP negotiations veteran and founding director of Satat Sampada Climate Foundation.
COP30 was billed as a landmark gathering, where countries would chart a course to dramatically cut climate pollution.
Instead, huge polluters have missed multiple deadlines to submit national climate goals, President Donald Trump is fresh from a speech calling climate change a "con job," the US says it will not send a delegation to the summit, and Brazil has just approved oil drilling at the mouth of the Amazon — all the while, global temperatures tick upward and climate targets slip out of reach.

Technologically advanced materials are reshaping sustainable construction as carbon-sequestering innovations progress from concept to deployment. Heidelberg Materials’ integration of CarbonCure concrete technology demonstrates how captured CO₂ can enhance strength while reducing the embodied carbon of materials, directly addressing the carbon footprint of construction. This marks a decisive step toward net zero whole life carbon outcomes and aligns with the broader drive to decarbonise the built environment through low carbon construction materials.
The sector is also seeing renewed focus on renewable building materials such as engineered timber. Products promoted by manufacturers like West Fraser highlight timber’s dual capacity for carbon storage and cost efficiency, reinforcing its role in sustainable building design. Architects and developers are now applying lifecycle assessment and whole life carbon assessment principles to balance structural performance, life cycle cost, and the environmental sustainability in construction practices.
Policy and regulation are reinforcing these shifts. Insights from COP30 and the UK’s fiscal frameworks confirm that sustainable building practices, embodied carbon reduction, and energy-efficient buildings form the basis for measurable sustainability within green construction policy. BREEAM and upcoming BREEAM v7 standards are accelerating adoption of eco-design for buildings, ensuring that net zero carbon buildings move from aspiration to obligation across urban infrastructure.
Emerging sensing and data systems are redefining resource efficiency in construction. High-resolution soil analysis tools such as those within the Earth Rover programme exemplify circular construction strategies, improving site selection and supporting the circular economy in construction by optimising natural carbon sinks and reducing environmental impact of construction.
This collective momentum signals the next phase in low carbon design: an integrated approach where low embodied carbon materials, sustainable material specification, and building lifecycle performance guide strategic investment. Sustainable architecture and eco-friendly construction are no longer niche pursuits but core drivers of carbon neutral construction and long-term environmental sustainability.
