Palawan, a cluster of islands in the Philippines, is breathtakingly beautiful, and the paradise archipelago has not gone unrecognized.
The entire area of Palawan, covering more than 1,700 islands, has been designated a biosphere reserve by UNESCO, and it also hosts two world heritage sites, the Puerto-Princesa Subterranean River National Park and Tubbataha Reefs.
But despite these designations, threats still remain from mining, the illegal wildlife trade, climate change and deforestation. According to Global Forest Watch, Palawan had the most tree cover loss in the country between 2001 and 2023.
Conservationist Karina May Reyes, who refers to herself as KM for short, is on a mission to protect the archipelago, alongside a small team of people that form the nonprofit Centre for Sustainability PH.
“Palawan is super special because from ridge to reef, you have pristine landscapes – mountains that still retain old growth canopy cover all the way to coral reefs that still have incredible biodiversity, whether you’re after manta rays or whale sharks or tiger sharks or turtles,” she tells CNN.

Sustainable construction is moving from ambition to delivery, with whole life carbon, embodied carbon and life cycle cost now shaping decisions on heat, materials and compliance.
New analysis suggests waste-heat networks and large air-source heat pumps could serve 70,000 new social and affordable homes at lower cost than electric panel heating, reducing energy bills by £142m. Record UK Boiler Upgrade Scheme heat-pump vouchers point to rising market confidence in low carbon building systems and energy-efficient buildings, strengthening the case for sustainable building design, low carbon design and net zero carbon buildings as practical infrastructure rather than policy rhetoric.
Circular economy in construction is gaining operational detail through new industry guidance on door reuse, supporting sustainable material specification, resource efficiency in construction and end-of-life reuse in construction.
The shift matters because embodied carbon in materials cannot be cut through cleaner cement alone. Contractors, insurers and regulators will need workable evidence routes for reused components, environmental product declarations (EPDs), lifecycle assessment and whole life carbon assessment if circular construction strategies are to compete with disposal. The priority is a reliable market for low embodied carbon materials, green building products, renewable building materials and low carbon construction materials that can reduce the carbon footprint of construction without creating unmanageable compliance burdens.
The central constraint is execution. Cleaner heat, eco-design for buildings, eco-friendly construction and safer delivery are meeting skills shortages, reskilling demands and post-Building Safety Act compliance pressures. Environmental sustainability in construction now depends on whether procurement teams, installers and building-control bodies can translate sustainable design into dependable, inspectable and affordable systems.
Net zero whole life carbon, BREEAM and BREEAM v7 ambitions will be won through building lifecycle performance, life cycle thinking in construction and carbon footprint reduction across design, specification, construction, operation and reuse. The strongest performers will be those able to make decarbonising the built environment a repeatable construction process, not a project-by-project aspiration.
