Registros de contaminación del aire y emisiones de gases de efecto invernadero no toman en cuenta la quema de plástico. Pero un estudio de 2023 liderado por Eri Saikawa, del proyecto Ecolectivos, estima que la quema de basura plástica en Guatemala, incluyendo la montaña en Santa María Xalapán, podría producir “incrementos considerables” de esas emisiones. Los resultados son alarmantes pero también sugieren que la quema de basura plástica es un problema mejorable, dijo Saikawa de la Universidad de Emory. “Simplemente creando acceso a recolección de basura, podríamos prevenir estas emisiones y mejorar la salud humana y del ecosistema.” Muchos guatemaltecos queman plástico para avivar los fuegos de su cocina o manejar la basura que se desborda, muchas veces sin saber que hacerlo libera microplásticos, compuestos carcinógenos, disruptores hormonales, y otros químicos tóxicos que puede afectar negativamente la salud humana.

Guatemala imported over 1.2 million tons of household plastics in a decade, with Chinese imports nearly tripling. Downtown Jalapa now hosts several stores devoted to selling plastic wares from China. Pungent plastic chemical odors fill Super China, where shelves overflow with mass-produced  plastic goods. Ecolectivos participants like Soila Elizabeth Cruz came up with strategies like community cleanups to reduce their need to burn plastic. Many women who worked with Ecolectivos still collect and sort items to recycle. But what’s really needed, they say, is a collection center for trash and recyclables. As hard as Ecolectivos participants are working to reduce their need to burn plastic, there is still so much plastic waste, many people feel they have no choice but to burn it.

BloombergNEF estimates the EU, UK and Norway must mobilise about $1.3 trillion annually to remain on a credible 2050 pathway, making the built environment a frontline priority. Deep retrofit, electrified heat, sturdier grids and climate adaptation now determine balance sheet resilience as much as operational performance. UK support for small-scale biomass has lapsed without replacement, signalling a shift toward technologies that prove sustainability and system value. Hydropower retains a role where environmental safeguards hold; biomass must meet robust criteria. Recent Himalayan floods underscore that resilience is part of the brief, not a discretionary line item. Designing for cascading hazards, redundancy and social equity is cheaper than rebuilding.

Investment and procurement need to prize whole life carbon, life cycle cost and lifecycle assessment. Clients and supply chains should embed whole life carbon assessment, cut embodied carbon through low embodied carbon materials and embodied carbon in materials verified by environmental product declarations (EPDs), and scale circular economy in construction via circular construction strategies, resource efficiency in construction and end-of-life reuse in construction. Targets for net zero whole life carbon and net zero carbon buildings require sustainable building design, eco-design for buildings, sustainable design and low carbon design aligned with BREEAM and BREEAM v7. Priorities include energy-efficient buildings, low carbon construction materials, renewable building materials, green building materials and green building products within sustainable material specification. Programmes that integrate green infrastructure, nature-based risk management and building lifecycle performance will accelerate decarbonising the built environment, deliver carbon neutral construction, reduce the carbon footprint of construction and mitigate the environmental impact of construction while advancing sustainable construction, eco-friendly construction, sustainable building practices and sustainable urban development.
