The 2023 Canadian forest fires released about 640 million metric tons of carbon, according to a @NASA study. That’s comparable to the annual fossil fuel emissions of a large industrialized nation. The fires were driven by Canada’s warmest and driest conditions in decades.
If events like these become more typical, they could impact global climate. That’s because Canada’s vast forests make up one of the planet’s important carbon sinks, meaning that they absorb more carbon dioxide from the atmosphere than they release.
In this animation showing data from summer 2023, carbon monoxide from Canada wildfires curls thousands of miles across North America. Lower concentrations are shown in purple; higher concentrations are in yellow. Red triangles indicate fire hotspots.
Image Description:
Data visualization over a map of North America. Most of the land is purple, which indicates lower concentrations of carbon monoxide. Large yellow and orange swirls start at fire hotspots in Canada and then sweep across the U.S. A color bar at the top of the video relates color to the concentration of carbon monoxide from Canada wildfires.

A £400m UK government loan to the Tropical Forests Forever Facility tightens the link between embodied carbon and real forest outcomes. Bio‑based and renewable building materials will now be judged on credible, deforestation‑free supply chains as much as on glossy lifecycle assessment or whole life carbon assessment outputs, driving wider use of environmental product declarations (EPDs), green building materials and green building products. Expect stronger traceability, circular construction strategies and end‑of‑life reuse in construction when specifying low embodied carbon materials and low carbon construction materials to cut the carbon footprint of construction and support the circular economy in construction.
Updated damp and mould guidance from the Chartered Institute of Building and the Chartered Institute of Housing reframes indoor environmental quality as a health obligation, pressing social landlords towards whole‑house ventilation, insulation upgrades and continuous monitoring. The shift embeds sustainable building design and energy‑efficient buildings as compliance issues, with implications for life cycle cost, building lifecycle performance and net zero whole life carbon pathways recognised by BREEAM and BREEAM v7.
A new retrofit procurement guide uses public spending to expand capacity, create local jobs and tackle skills shortages by baking training and labour targets into contracts. This gives sustainable construction and decarbonising the built environment delivery teeth, promoting life cycle thinking in construction, resource efficiency in construction and eco‑design for buildings, alongside sustainable material specification and low carbon building upgrades that support carbon neutral construction.
Escalating climate risks—from European wildfires to transboundary smoke and cascading Himalayan floods—are accelerating environmental sustainability in construction and sustainable urban development. Design for resilience is becoming core to net zero carbon buildings and green construction, with fire‑hardening, smoke filtration, heat‑safe interiors and green infrastructure specified to reduce the environmental impact of construction, deliver carbon footprint reduction over whole life carbon and strengthen eco‑friendly construction and sustainable architecture.
