At most places Melissa Valliant goes when dining out, she carries in her backpack a set of reusable flatware — prepared to refuse the disposable utensils she says are part of the plastic pollution crisis that's inextricably linked with the climate crisis.
Some reports estimate that potentially between 36 billion and 40 billion plastic utensils are used every year just in the United States, which is more than 100 million per day, Valliant said.
You might think recycling plastic flatware may offset the harms of using it. But as of 2018, only 9% of all the plastic the world has ever produced — around 9 billion metric tons or nearly 10 billion US tons — had been recycled, according to a report by the United Nations Environment Programme. What isn't recycled or thrown away is burned or littered, experts said. Burning plastic utensils releases carbon dioxide into the environment, Dr. Jillian Goldfarb said, and an incinerator that isn't at peak performance can release particulate matter and carbon monoxide.
To limit your use of plastic flatware, you could switch to compostable, bamboo or metal options, all of which generally require or produce significantly less energy, water, waste or emissions, Goldfarb said. Producing a pound of bamboo forks, for example, expends 0.46 kilowatts per hour, whereas making a pound of plastic forks expends 11 kilowatts per hour, according to Goldfarb. (Manufacturing metal utensils, however, does require more water than plastic utensils.)
But you don't have to buy a reusable set from a trendy environmental store — you can just use what you already have, Valliant
said.

Ocean governance reforms now carry direct consequences for sustainable construction and environmental sustainability in construction. The UN High Seas Treaty and proposed protections for the Antarctic Peninsula introduce stricter environmental impact assessments for offshore and coastal developments, signalling an era of detailed whole life carbon assessment in marine-related infrastructure. Developers of subsea cables, interconnectors, and CO₂ pipelines will contend with extended consenting processes and biodiversity restrictions that influence material selection, eco-friendly construction practices, and low carbon design decisions across multiple jurisdictions. The evolution of marine spatial planning aligns with circular economy in construction principles, recognising supply-chain carbon exposure as both a design and compliance issue.
Trade policy disruption poses further challenges to sustainable building design. Prospective tariffs on low-carbon materials—such as green building materials, steel, engineered timber, and heat-pump components—threaten project timelines and budgets. Anticipated responses include regional procurement strategies, adoption of sustainable material specification, and more rigorous evaluation of embodied carbon in materials and life cycle cost performance. Demands for verifiable environmental product declarations (EPDs) and building lifecycle performance metrics are expected to rise as clients seek transparency for carbon neutral construction targets.
Climate volatility is reshaping low-impact construction strategies, particularly in flood-prone and mountainous regions. Designers must adopt adaptive lifecycle assessment frameworks that prioritise redundancy, attenuation, and slope stability. These approaches support net zero whole life carbon goals and reduce the carbon footprint of construction, reinforcing resilience and resource efficiency in construction.
The policy debate on decarbonisation is shifting toward measurable outcomes. Governments are preparing performance-linked procurement and finance mechanisms that embed whole life carbon benchmarks into material supply chains. The accelerating move toward net zero carbon buildings, green construction, and BREEAM V7 standards signals the transition from intent to implementation. Markets for low embodied carbon materials and circular construction strategies are scaling at pace, defining a new baseline for sustainable building practices and comprehensive whole life carbon accountability across the global built environment.
