Global Status Report for Buildings and Construction 2024-2025

March 18, 2025

In 2024, the building and construction sector’s emissions did not increase for the first time since 2020. This milestone was reported by the United Nations Environment Programme (UNEP) and the Global Alliance for Buildings and Construction. Despite this progress, the sector still accounts for over a third of global emissions. The Global Status Report for Buildings and Construction 2024-2025, released on March 17, 2025, indicates that decarbonisation efforts are beginning to yield results.

Current Emission Trends

The building sector’s emissions stabilised in 2024. This marks a very important shift in a sector that has long been a substantial contributor to climate change. The energy intensity of buildings decreased by nearly 10 per cent. Additionally, the proportion of renewable energy in final energy demand rose by about 5 per cent.

Importance of Policy Implementation

The report emphasises the urgent need for ambitious energy codes. Almost half of the world’s future buildings are yet to be constructed. Therefore, implementing strong energy policies is crucial. Currently, over 50 per cent of new buildings in emerging and developing economies lack such regulations.

Key Measures for Decarbonisation

The adoption of zero-carbon building energy codes is essential. Major carbon-emitting countries should implement these codes by 2028. All other nations are encouraged to follow suit by 2035. This measure is critical for achieving global climate objectives.

Financial Investments Required

Investment in building energy efficiency must increase . The sector needs to double its investments from $270 billion to $522 billion by 2030. This funding is vital for implementing measures such as circular construction practices, green leases, and energy-efficient retrofitting.

Challenges in Material Use

Construction materials like cement and steel contribute to emissions. They account for 18 per cent of global emissions and generate substantial waste. Addressing these challenges is necessary for reducing the sector’s environmental impact.

Workforce Development Needs

The building sector faces skill shortages. Workforce development programmes are essential to equip workers with the necessary skills for a sustainable future.
