Guyana, a former Dutch then British colony that gained independence in 1966, is one of only a handful of countries that is a “carbon sink,” meaning it stores more planet-heating pollution than it produces. This is due to its vast rainforest; trees remove carbon dioxide from the atmosphere as they grow. But the tiny country — sandwiched between Brazil, Venezuela and Suriname — has tightly embraced oil as a route to prosperity. In December 2019, then-President David Granger said in a speech, “petroleum resources will be utilized to provide the good life for all … Every Guyanese will benefit.” It’s a narrative that has continued under current President Mohamed Irfaan Ali, who says new oil wealth will allow Guyana to develop better infrastructure, healthcare and climate adaptation. And while plenty of Guyanese people welcome the new oil industry, some say Guyana’s startling economic statistics do not reflect a real-world prosperity for ordinary people, many of whom are struggling with the higher prices accompanying the oil boom. Inflation rose 6.6% in 2023, with prices of some foods shooting up much more rapidly. CNN contacted President Ali, the Ministry of Natural Resources and the Ministry of Finance for comment on this story but received no response.

Climate damage and material waste are reshaping sustainable construction more forcefully than certification culture. The loss of 38 homes to wildfire in the Midlands has exposed the need for sustainable building design that treats fire resilience, flood resistance and passive survivability as core requirements. Shropshire fire crews’ warnings over escalating wildfire and flooding extremes underline a decisive shift for green construction: buildings must be designed for volatility, not historic weather patterns.

The UN’s warning that climate impacts could displace millions across South Asia raises direct implications for environmental sustainability in construction.

Large-scale migration would intensify pressure on housing delivery, infrastructure finance, sustainable urban development and supply chains for low carbon construction materials. Adaptation is now a construction pipeline issue, requiring life cycle thinking in construction, robust building lifecycle performance and a clearer link between resilience, life cycle cost and whole life carbon.

Materials innovation is moving towards the circular economy in construction. Plans for a wind turbine recycling facility at the Port of Inverness show renewable infrastructure confronting end-of-life reuse in construction. The sector’s claims on circular economy performance will increasingly depend on measurable circular construction strategies, resource efficiency in construction and sustainable material specification, not marketing language. Embodied carbon, embodied carbon in materials and the carbon footprint of construction must be assessed alongside operational energy if net zero carbon buildings and net zero whole life carbon targets are to be credible.

Research converting waste plastics, packaging and old CDs into polymer networks that harvest moisture from air points to future green building products and construction-adjacent materials for water-stressed regions. The science remains early stage, yet it supports the wider move towards low embodied carbon materials, renewable building materials where appropriate, and practical eco-design for buildings.

Laboratory findings showing duct tape outperforming sandbags as a flood defence reinforce a key lesson for sustainable architecture: resilience can come from inexpensive, rapidly deployable measures as well as major green infrastructure. The direction is clear. Sustainable construction is expanding beyond carbon accounting into whole life carbon assessment, lifecycle assessment, low carbon design, circular economy principles and climate practicality. The strongest projects will combine energy-efficient buildings, lower embodied carbon, carbon footprint reduction and durable adaptation to a harsher world.
