Best Practice Network

What is a Best Practice Network?

A Best Practice Network is an institution staffed by technical experts who help decision-makers design, implement, and enforce proven policies that reduce green house gas emissions. These organisations are global leaders in their fields aiming at:

  • Collecting the best policies that are proven to be effective and technically feasible around the world
  • Learning from them (successes and failures)
  • Helping design policy-packages to develop them in each region

Legal Status

What is the GBPN’s legal status?

The GBPN is a non-for-profit organisation registered as an “association” under French law, advancing knowledge and expertise on building energy efficiency and performance.

The GBPN was established by the ClimateWorks Foundation in 2011.

The GBPN is the ClimateWorks’ Best Practice Network for the building sector.

Climateworks Foundation

What is the ClimateWorks Foundation?

The ClimateWorks Foundation is a non-for-profit organisation launched in 2008 to support public policies that prevent dangerous climate change and promote global prosperity.

Based in San Francisco, California, the ClimateWorks Foundation focuses in the regions and sectors responsible for most of the world’s carbon emissions (power, industry, buildings and appliances, transport, and forests and land use). 

ClimateWorks partners with an international network of affiliated organisations—the ClimateWorks Network—to promote these policies in the geographic regions and economic sectors that have the greatest potential for reducing greenhouse gas emissions.

GBPN Funders

Who are the GBPN funders?

The GBPN was launched in 2011 with the support of the ClimateWorks Foundation that is majority funded by the: the William and Flora Hewlett Foundation, the McKnight Foundation, and the David and Lucile Packard Foundation.

GBPN Regional Hubs

What are the GBPN Regional Hubs? What is their role?

The GBPN Regional Hubs, either housed at an existing organisation or operating as an independent institution, officially represent the GBPN Network in their region.

There are currently four regions in which hubs are active:  the United States, Europe, China, and India.


Our Regional Hubs and Partners provide the most up-to-date knowledge and data on building energy policies to decision-makers and other key stakeholders within their region, while documenting best practices, lessons learned and monitoring progress with the Global Centre. Coordinated by the Global Centre, we develop strategically aligned work programs designed to ensure the building sector has the intelligence required to play its significant role in tackling climate change.


What are our values?

  • Ambition in terms of achieving the GHG abatement potential of the building sector in its core regions (cf. Our Vision).
  • Independence: the GBPN is a neutral and politically independent organisation conducting cross-cutting analysis for various building sector decision-makers. Its independence facilitates unbiased interactions with its stakeholders and builds its credibility as a source for objective and rigorous research (cf. What we do).
  • Collaboration: the GBPN and its Regional Hubs are mutually dependent on each other for the success of their policies. Collaboration is the key to decision-making.
  • Learning: the GBPN is a learning network which evaluates its successes and failures by using various indicators such as GHG intensity and emission reductions (cf. Our Network).
  • Leadership: the GBPN is a collaboration between the world’s leading building energy policy-related organisations and experts, which strives to be a leader in terms of reducing GHG emissions in the building sector (cf. What we do).
  • Culture/local context: although climate change is a global issue, the GBPN believes that the solutions for reducing building energy use are fundamentally local. Therefore, its work must be relevant and tailored to the cultures and contexts where it occurs (cf. What we do).
  • Creativity: the GBPN’s scope of work is as much creative and imaginative as it is methodical and analytical. 
  • Wellbeing: the GBPN strives for contributing to the planet’s economic and social wellbeing by engaging the building sector to apply its Deep Path (cf. Our Vision).

The Deep Path Strategy

What Policies are most cost-efficient and effective in reducing CO2 emissions related to building energy use? What is the ‘Deep Path’ Strategy?

GBPN’s Global research strategy for generating supporting knowledge for policies that enable today’s state of the art building energy performance codes and complimentary policies to be optimized in regional jurisdictions towards net zero energy targets for new buildings and deep renovation for existing buildings. This translates into a strategic definition of best-practice actions as being those that encourage adoption of policy frameworks for achieving:

  • Net zero energy performance in new buildings;
  • Increased rate of deep renovation of existing buildings.

Achieving these goals required building knowledge on the state of play and state of the art in four key enablers:

  • Financing & Co-benefits
  • Performance codes, data and mandatory rating & disclosure policies
  • Policies for integrated renewable energy in building developments;
  • Compliance with mandatory performance requirements.

The Global program will conduct cross-cutting research on status and state of the art in each of these themes and share best-practices between the regions. We will amplify the impact of the research program beyond our focus regions by facilitating knowledge exchange and leveraging impact and spill over by partnering with multi-lateral and other key global initiatives.

Mitigation Potential

What is the GHG Mitigation Potential of Buildings Globally?

At Least 2.1Gt CO2 by 2030 & 3.2Gt CO2 by 2050 from reducing energy demand for providing thermal comfort in buildings.

What is the GHG Mitigation Potential of the Buildings in China?

Without carrying out specific energy efficiency measures, China will face a growth of almost 160% in buildings’ energy use by 2050. If current policy trends are followed up to 2050, the projected growth of CO2 emissions in China will increase to 1.6 Gt however, if a “deep” scenario is implemented this can be reduced by half to 0.84 Gt by 2050. This means that despite the expected growth seen by the Chinese building sector, implementing the Deep Path strategy would enable its buildings’ energy demand and associated GHG emissions, to be maintained almost at today’s levels.  

What is the GHG Mitigation Potential of the Buildings in India?

If today’s policy trends are followed, India’s building thermal energy demand will grow by almost 700% by 2050 compared to 2005 levels and the associated CO2 emissions are likely to increase tenfold (1.1 Gt). It is therefore critical to implement the “Deep Path” strategy.  Even with the very ambitious “deep” strategy, India’s building thermal energy use is expected to grow by 130% by 2050. The “deep” scenario would also contain the CO2related emissions from a growth of 1.11 Gt to a growth of 0.44 Gt.

What is the GHG Mitigation Potential of the Buildings in the USA?

More than 1.2 Gt CO2 by 2030 & around 1.8 Gt CO2 by 2050 can be saved compared to today's carbon emissions.

What is the GHG Mitigation Potential of the Buildings in the EU?

Among all regions, the EU is the one that can achieve the greatest reduction in thermal energy use (65%) and CO2 emissions (66%) by 2050 compared to 2005 levels despite an increase in floor area (by 27%), population and economic activity. Just under 1 Gt CO2 by 2030 and more than 1.3 Gt CO2 by 2050 can be saved compared to today's carbon emissions.
