Sustainable transformation in the buildings and construction sector
Sustainable transformation in the buildings and construction sector
Due to increasing global environmental challenges and pressing pressures to reduce carbon emissions and improve energy efficiency, the buildings and construction sector is emerging as a pivotal element in achieving environmental sustainability. Buildings are not only places for residence and work, but rather they are pillars through which we can reshape the features of our environmental future.
This is because the building sector is one of the most energy consuming sectors, and a major source of carbon emissions, as the design and operation of buildings often depend on non-renewable energy sources. Therefore,Earth Guardsin this article addresses the importance of sustainable transformation in this vital sector, in a way that ensures environmental sustainability; So read on, and discover practical solutions and promising opportunities that restore hope in building a green world.
The role of the building sector in combating climate change
Global reports for the years 2024-2025 indicate that buildings and facilities contribute to nearly a third of global emissions, and are responsible for generating nearly a third of the world’s waste. However, this sector is witnessing a noticeable improvement in energy efficiency and the adoption of renewable energy sources, according to a report issued a few days ago by the United Nations Environment Program (UNEP) and the Global Alliance for Buildings and Construction (GlobalABC).
At a time when the need to improve energy efficiency and adopt modern, environmentally friendly building standards has become an urgent necessity to support efforts to build sustainable cities and communities, this sector is considered an essential pillar for achieving Goal (11) of the United Nations Sustainable Development Goals (SDGs) “Sustainable Cities and Local Communities,” which focuses on building cities and urban monuments that preserve the environment and ensure quality of life.
Improving energy efficiency
Reports indicate that the policies adopted since the signing of the Paris Agreement in 2015 until 2023 have achieved tangible results, despite the need to accelerate and expand the scope of their implementation. In 2024, for the first time, we were able to decouple the continued growth in building construction from the increase in greenhouse gas emissions, as emissions stopped rising and energy intensity recorded a decline of 9.5%, which shows remarkable progress.
A group of measures contributed to achieving this achievement, including the implementation of mandatory building energy laws compatible with Net Zero Emissions standards, as well as mandatory performance standards and large investments in energy efficiency. As a result of these measures, the energy intensity of the sector decreased by about 10%, while the share of renewable energy in final energy demand increased by about 5%.
Economic and investment challenges
The building sector faces major economic challenges as energy demand shifts; It is expected to reach its peak in high-income countries by 2030; Demand rates will begin to decline at a rate of 0.3% annually until 2050. In contrast, middle- and low-income countries will witness an increase in demand of 1.5% until 2030, followed by a decrease of 1.3% annually until 2050.
The United Nations Environment Program report indicated that global investment in energy efficiency in buildings has witnessed a 7% decline to reach $270 billion in 2023 compared to $290 billion the previous year. Despite this decline, an investment gap of about $1.1 trillion emerges to achieve optimal use of energy in this vital sector. Which requires intensified efforts and investments to compensate for this shortage.
Future policies and solutions
The importance of intensifying efforts to renovate existing buildings is highlighted by adopting energy-saving designs and adopting cooling systems based on heat pumps, with the aim of reducing energy intensity by up to 35% by 2030. It is expected that the world will witness the construction of a large number of buildings by 2050, and about half of these buildings have not yet been constructed. This requires the adoption of new and strict building laws aimed at reducing future emissions, in addition to updating building standards to ensure true environmental sustainability.
At the global level, 30 countries have imposed the use of renewable energy sources in the construction sector, in a step that reflects the trend towards a cleaner and more sustainable environment. The decline in natural gas consumption by more than 4% demonstrates the importance of adopting innovative solutions, such as green leases for low-carbon offices, a model that more than 7,600 companies – within the Organization for Economic Co-operation and Development – have begun to implement.
Sustainable transformation efforts in the building sector are witnessing the adoptionCircular construction practicesand the use of recycled materials; These methods contributed to achieving about 18% of the total construction inputs in Europe. Strategies to expand producer responsibility – applied in countries such as the Netherlands, France and India – have also reduced waste and improved resource efficiency. Which confirms the growing trend towards more sustainable building models.
In light of these promising data, Earth Guards call for enhancing investment in energy efficiency in buildings. Achieving a real transformation in this sector requires doubling annual investments from $270 billion to reach $522 billion by 2030. So that we can achieve the Sustainable Development Goals (SDGs).
