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.

Global negotiations at COP30 in Belém have accelerated momentum toward decarbonising the built environment through definitive timelines for ending fossil fuel use. The shift transforms sustainable construction from voluntary ambition into a structural requirement for net zero carbon and net zero whole life carbon outcomes. Policymakers are converging around frameworks that demand whole life carbon assessment and lifecycle assessment to account for embodied carbon across sustainable building design, low carbon construction materials and circular economy in construction principles.
Funding imbalances remain acute. Only a fraction of climate finance supports environmental sustainability in construction and resilient infrastructure, leaving gaps in life cycle cost modelling and resource efficiency in construction. Addressing this shortfall is critical to accelerating carbon footprint reduction and life cycle thinking in construction that ensures buildings can adapt to climatic extremes while achieving carbon neutral construction.
Government proposals linking climate, biodiversity and land use through unified policy instruments indicate an evolution toward circular construction strategies and eco-design for buildings that integrate sustainable material specification and environmental product declarations (EPDs). These measures align with BREEAM and the forthcoming BREEAM v7 standards, reinforcing quantitative accountability in green construction and sustainable building practices.
In the United Kingdom, scrutiny from Parliament’s Environmental Audit Committee challenges the misconception that regulation limits housing delivery. Its evidence underscores that low carbon design and green infrastructure are enablers of innovation, not barriers. It signals a policy turning point toward sustainable urban development and eco-friendly construction anchored in end-of-life reuse in construction and building lifecycle performance metrics.
The trajectory is apparent: whole life carbon accounting, embodied carbon in materials tracking and circular economy integration are reshaping global market expectations. Sustainable design decisions are becoming quantifiable obligations, ensuring every low carbon building advances environmental sustainability in construction and measurable carbon footprint of construction reductions consistent with decarbonising the built environment.
