Urban Arborization: A Nature-Based Solution (NbS) for CO₂ Offset in the Construction Sector

Resumo

The construction sector is responsible for about 37% of global energy-related CO₂ emissions, reaching record levels in 2021, with a 5% increase compared to 2020. This growth undermines the 2050 decarbonization targets, requiring innovative solutions to mitigate its environmental impact. This article proposes urban reforestation, through planned tree planting, as a nature-based solution (NbS) for capturing and storing CO₂ generated in urban areas from new construction sites. In addition to capturing CO₂, tree planting offers additional benefits such as improving air quality, reducing energy consumption, combating global warming, and promoting health and well-being. The study examines the gap between the sector's climate performance and the urgent need for decarbonization, considering sustainable practices aligned with ESG principles and the UN Agenda 2030 guidelines.
