One industry,
construction,
emits 6384 million metric tons of greenhouse gases!
Buildings emit 40% of energy-related carbon emissions. Around 25% of those emissions are from actual construction and materials. Electricity, lighting, heating and more for buildings are increasing this number, (Carbon Footprint in Construction; Ultimate Guide in 2024 - Neuroject, 2024)
Debris is a transparent killer, polluting the air and us. It travels around without you knowing, and can come in many forms, such as dust. Debris, created from demolition, has many types, but the main one is concrete. Metal and wood debris are also common. Destroying areas can release chemicals that are harmful. This can be easily prevented by being responsible about using these materials (Ehinger, 2024). In the future, turning them into something useful and healthy for the environment could be a solution to the debris climate crisis.
Animals have been effected due to the amount of deforestation for construction materials (Stand For Trees, 2025). They can be killed or injured during the construction of a building. Finding food, breeding, and adapting to climate change is harder now, from noise and light from machinery, since they have to avoid that area. This leads to them needing to travel longer to find food, and/or compete with other animals for resources. Buildings also can block movement. (Wildlife Trusts, n.d.) Deforestation is covered more in our "Causes + Impacts" section.
Construction is a massive player in the climate crisis. The entire construction sector contributes 25%-40% of the world's carbon emissions. It is by far one of the largest emitter of greenhouse gases. The production and use of materials such as cement, steel, and aluminum have a significant carbon footprint. Construction also causes water pollution. Harmful chemicals used during construction can harm both workers and the environment (How Does Construction Impact the Environment, n.d.). According to NOAA, 230 to 600 million tons of waste comes from construction, mostly from construction and demolition debris (Construction and Demolition Debris: Material-Specific Data, n.d.)
PROS
Construction does have a positive side. Construction projects play a critical role in impacting the social and economic factors of cities and towns. Through the creation of jobs, the amplification of local businesses, and the gaining of investments, construction projects can have a positive long-term effect on the cities they serve. Construction can also help build homes and local buildings that help the community (The Impact of Construction on Communities, 2024).
