The Global Alliance for Buildings and Construction (GABC) contributes to the
common objective of the Paris Agreement of limiting global warming to well below 2°C.

The Global Alliance for Buildings and Construction (GABC) is an initiative launched at COP21, as part of the Lima Paris Action Agenda. It aims to mobilise all stakeholders, including member states and non-state actors from the Buildings and Construction sector to scale up climate actions in the sector. The GABC focuses on the achievement of the low-carbon and energy transition through fostering the development of appropriate policies for sustainable, energy efficient buildings, which allows a concrete value-chain transformation of the sector.

Specifically, the GABC aims at supporting and accelerating the implementation of Nationally Determined Contributions (NDCs). It is committed to putting the buildings and construction sector on the below 2 °C path. The Alliance thus facilitates the implementation of the Paris Agreement for the buildings and construction sector in terms of energy efficiency gains, growth of renewable energy, GHG emissions reduction, and increasing the share of eco-friendly buildings, whether new or renovated. Today, the GABC gathers 24 countries and 72 non-state organisations (sub-national, non-governmental organisations and private sector) from all over the world. It intends to increase the pace and scale of actions through communication, collaboration and implementation.

The GABC has three Common Global Objectives:

Communicate: Raising awareness and engagements in order to make visible the magnitude of the opportunities and impacts in the buildings and construction sector, define sectoral climate goals and promote transparency and information exchange.

Collaborate: Further enabling actions on public policies and market transformations to achieve existing climate commitments, through implementing partnerships, sharing technology and know-how, and improving deal-flow and facilitate access to efficient financing and funding.

Solutions: Offering programs for further ambition and locally adapted solutions that firmly put the buildings sector on a below 2 °C path: increasing efficiency of buildings systems and envelope, mainstreaming low GHG materials, low-emission new buildings and scaling up deep renovation.

GABC activities are organized around 5 different Work Areas contributing to the transition towards low-GHG and resilient real estate:

Education and Awareness

Public Policies

Market Transformation

Finance

Building Measurement, Data and Information

The GABC Secretariat is hosted by UN Environment's Economy Division.

Towards a zero-emission, efficient, and resilient buildings and construction sector - presenting the GlobalABC Global Status Report 2018
about_presentation
This Global Status Report documents the status and trends of key indicators for energy use, emissions, technologies, policies, and investments to track the buildings and construction sector, globally and in key regions. Central findings of this report in clude:
Buildings play a dominant role in the clean energy transition. Buildings construction and operations accounted for 36% of global final energy use and nearly 40% of energy‐related carbon dioxide (CO) emissions in 2017.
 
Global buildings sector energy use continues to grow, but not as quickly as population or floor area. Heating, lighting and household cooking are the most improved building end uses. Continued increases in population and floor area are and will be the principal factors of rising energy demand in buildings.
 
Buildings and construction sector emissions appear to have levelled off since 2015, although they still represent the largest share of total global energy‐related CO2 emissions.
 
A clean energy transition will enable a steady decrease in future emissions.
 
Global dialogue is supporting progress in developing policies for sustainable buildings.
 
Most countries have submitted nationally determined contributions (NDCs) that relate to buildings and some have improved them; however, many NDCs still lack specific actions.
 
Countries are continuing to implement and update building energy codes and certification policies. However, most expected future buildings growth is in countries that do not have mandatory energy codes and policies in place today.
Investment in energy efficiency in buildings has slowed. Incremental energy efficiencyinvestment increased by 4.7% in 2017 (3% adjusted for inflation), which is the lowest rate of increase in recent years.
