‘More and Faster’: UN Calls to Shrink Buildings’ Carbon Footprint

Countries must move rapidly to slash CO2 emissions from homes, offices, shops and other buildings -- a sector that accounts for a third of global greenhouse gas pollution, the United Nations said Monday.

Carbon dioxide emissions from the building sector rose around five percent in the last decade when they should have fallen 28 percent, according to a new report by the United Nations Environment Program (UNEP).

It said emissions had plateaued since 2023 as climate policies began to have an impact, particularly green building standards, the use of renewable energy and electrified heating and cooling.

But the building sector still consumes 32 percent of the world's energy and contributes 34 percent of CO2 emissions, the report found.

"The buildings where we work, shop and live account for a third of global emissions and a third of global waste," said Inger Andersen, Executive Director of UNEP.

"The good news is that government actions are working. But we must do more and do it faster."

She called on nations to include targets to "rapidly cut emissions from buildings and construction" in their climate plans.

The report said that while most of the countries that signed up to the 2015 Paris climate deal -- nearly 200 have signed -- mention the sector, so far only 19 countries have sufficiently detailed goals in their national carbon cutting plans.

The report said that as of 2023, important metrics like energy-related emissions and the adoption of renewable energy "remain well below required progress rates".

That means that countries, businesses and homeowners now need to dramatically pick up the pace to meet the 2030 emissions reduction targets.

- 'Critical challenge' -

Direct and indirect CO2 emissions will now need to fall more than 10 percent per year, more than double the originally envisaged pace.

The rollout of renewables is a similar story.

The share of renewables like solar and wind in final energy consumption rose by only 4.5 percentage points since 2015, well behind the goal of nearly 18 percentage points.

That now needs to accelerate by a factor of seven to meet this decade's goal of tripling renewable energy use worldwide, UNEP said.

The report urged countries to accelerate the roll-out of renewable technologies and increase the share of renewables in the final energy mix to 46 percent by 2030 -- a rise of around 18 percent.

It also called on policymakers to increase energy efficiency retrofits to include better design, insulation and the use of renewables and heat pumps.

More work also needs to be done to improve the sustainability of materials like steel and cement, whose manufacture accounts for nearly a fifth of all emissions from the building sector.

But the report did say that circular construction practices were increasing in some areas, with recycled materials accounting for 18 percent of construction inputs in Europe.

The authors urged all major greenhouse gas emitters to take action by introducing zero-carbon building energy codes by 2028, and called on other countries to create and tighten their regulations within the next 10 years.

The report highlighted positive national policies from China, France, Germany, Mexico and South Africa among others.

But it said financing remained a "critical challenge".

In 2023, it found that global investment in energy efficiency in buildings fell seven percent from a year earlier to $270 billion, driven by higher borrowing costs and the winding back of government support programs, notably in Europe.

Those investments now need to double -- to $522 billion -- by 2030, it said.

A recent Saudi delegation’s visit to China marked a significant step toward deepening environmental cooperation between the two countries, with a focus on reforestation technologies and combating desertification, said Khaled Alabdulkader, CEO of the National Center for Vegetation Cover Development and Combating Desertification (NCVC).

Alabdulkader said the visit, led by Environment, Water and Agriculture Minister Abdulrahman Al-Fadley, included high-level meetings and site visits to explore China’s pioneering experiences in land reclamation and vegetation cover development.

In remarks to Asharq Al-Awsat, Alabdulkader described the trip as “rich and beneficial,” revealing that a memorandum of understanding was signed between the NCVC and China’s Gansu Desert Control Research Institute.

The agreement follows a Saudi Cabinet resolution passed in December 2023 authorizing the minister to negotiate and sign the MoU to strengthen cooperation in combating desertification.

The Saudi delegation met with executives from major Chinese firms to discuss launching joint investment projects in Saudi Arabia, including initiatives in natural resource management, rangeland rehabilitation, and the development of desert parks and eco-resorts, said Alabdulkader.

The discussions also explored transferring tree-planting technologies and desertification control methods as part of the Kingdom’s broader push to promote green economic growth and sustainability, he added.

“We aim to localize these technologies to help achieve our environmental goals and enhance sustainability in Saudi Arabia,” Alabdulkader said, expressing hope for expanded collaboration and further agreements building on the outcomes of the visit.

Talks also covered advanced techniques in mangrove cultivation, which are critical for coastal protection and boosting vegetation, as well as environmental protection innovations and the economic potential of invasive plants, including converting them into eco-friendly products.

Additionally, Alabdulkader held discussions with a Chinese environmental design company to explore cooperation on national park and wetland development in Saudi Arabia.

The visit, reported by the Saudi Press Agency (SPA), aimed to strengthen the strategic partnership between Saudi Arabia and China in the sectors of environment, water, and agriculture.

The visit also sought to open new export channels for Saudi products to the Chinese market and facilitate the introduction of more than 20 new food products from Saudi Arabia.

As part of the official visit, the Saudi delegation participated in the Saudi-Chinese Forum for Exporting Saudi Products and Agricultural Sustainability.

The forum concluded with the signing of 57 agreements and MoUs between 36 Saudi and Chinese entities, with investments exceeding SAR 14 billion ($3.7 billion).

These included 26 export agreements and 14 MoUs between the National Center for Palms and Dates and various Chinese companies and government agencies, aiming to boost global visibility and exports of Saudi dates and date-based products.
