‘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.



Injured Seals Get Care and Sanctuary at a New Center in the Netherlands

Gliding gracefully through the waters at his new home, Witje pauses briefly to peer through a large window at the curious and admiring visitors.

The 4-month-old gray seal is a lucky survivor able to swim in one of nine new tanks at the World Heritage Center, or WEC, a recently opened seal rescue facility in Lauwersoog, in the north of the Netherlands.

He was brought in after being orphaned and was suffering from a swollen flipper and a damaged eye.

“On a yearly basis, we roughly treat about 200 seals,” Sander van Dijk, the curator of the center, told The Associated Press. In 2024, researchers at Wageningen University in the Netherlands counted around 24,000 seals across the Wadden Sea.

Most are pups who get separated from their mother, known as howlers for their plaintive wailing. Others are injured by floating debris or are struck by passing vessels.

“If we look at our own data over the past 15 years, we just see every year more seals that somehow get entangled in waste in the sea, mostly fishing nets,” Van Dijk said.

The WEC, which officially opened to the public Saturday, replaces the Pieterburen Seal Center, a rescue facility set up in 1971 to treat injured seals found in and around the nearby Wadden Sea, which is a UNESCO World Heritage Site.

Witje’s tank is an upgrade from his previous quarters. He gets to swim in water directly from the sea, rather than tap water, in order to maintain a habitat as close as possible to the seals’ natural environment.

“They are adapted to living in seawater. It’s good for their fur. But also seawater, through its salt, has some properties that makes wounds heal faster,” Van Dijk said.

The WEC can treat around 70 seals at a time and has 12 intensive-care units for animals with serious injuries who are able to recover in special enclosures which offer a calm environment. They are prevented from swimming in order to rest and the space is cleaned frequently to prevent infections from waste.

The new building, which cost over 40 million euros ($45 million), with financing provided by local and regional governments as well as charitable organizations, tells more than just the story of the seas. It’s an educational space which teaches visitors about the Wadden Sea, the largest continuous system of intertidal flats in the world, extending along the coasts of the Netherlands, Germany and Denmark.

The new facility is significantly closer to the sea than the previous location. The tanks for the 10 seals currently residing at WEC look out over the water. Caregivers at the center are optimistic that Witje will soon recover enough to be released back into the waves.
