2022 GLOBAL STATUS REPORT FOR BUILDINGS AND CONSTRUCTION
FOREWORD
The warnings issued by the Intergovernmental Panel
on Climate Change (IPCC) about the consequences of
climate change are no longer warnings. They are reality.
In 2022, we saw heatwaves across the globe. We saw
saw droughts that are threatening the food security of
millions of people. If we do not rapidly cut emissions
in line with the Paris Agreement, we will be in deeper
trouble.
Decarbonizing the buildings sector by 2050 is critical to
delivering these emission cuts – and to addressing the
wider triple planetary crisis of climate change, nature
and biodiversity loss, and pollution and waste. However,
as the 2022 Buildings Global Status Report shows, the
sector is not making the deep systemic changes needed
to get on the path to this goal.
After the pandemic slowdown, the sector’s operational
emissions in 2021 rebounded to two per cent more than
the all-time high set in 2019. One positive sign is that
per cent in 2021, but this growth is tentative in the face
of a cost-of-living crisis in 2022 and must be sustained
to achieve building sector decarbonisation. Building
sector energy intensity did not improve in 2021 and
renewable energy growth in buildings remains modest,
Yet, as the report shows, the sector can change. For
example, rising fossil fuel costs make continued
although the erosion of purchasing power might slow
investment. The solution may lie in governments
directing relief towards low and zero-carbon building

vulnerable to energy price shocks.
There are also opportunities in rethinking construction
materials. Raw resource use is predicted to double by
and steel already major contributors to greenhouse gas
emissions. However, the sector can reduce its impact
by, for example, looking at alternative materials and
decarbonizing cement. The use of alternative materials
is particularly relevant for the African continent, a
special focus of the report. Much of the new housing
stock over the coming decades will be built in Africa.
To avoid increasing emissions and create buildings that
are resilient to the impacts of climate change, African
countries should look at sustainable construction
materials and techniques, in which the continent is rich.
Yes, we are running out of time to get on top of the
triple planetary crisis. Yes, the buildings sector is not
doing enough to change. However, by following the
recommendations in this report, the sector can catch
up and create buildings that are zero-carbon, resource-
