Introducing Achieving Zero: a “how-to” framework and a set of tools to enable cities and sub-national governments (state, provincial, and regional) to achieve crucial emissions reduction targets in the building sector.

International Finance Corporation and Architecture 2030 Collaborate on Zero Net Carbon Buildings for the developing world.
We are facing two very different and defining moments in history, the ratification of the Paris Climate Agreement and the results of the 2016 U.S. presidential election.
In late October, a historic two-day forum and workshop event was held in Wuhan, China. Organized by the China Exploration & Design Association Architecture Branch (CEDAAB) and Architecture 2030, this event established Zero Net Carbon (ZNC) as a necessary and achievable goal for buildings and developments.
Representatives from ten Green Building Councils (GBCs) worldwide – Canada, Germany, United States, China, India, South Africa, Australia, Brazil, The Netherlands and Sweden – together with the World Green Building Council (WGBC) and lead partner Architecture 2030, met in New York City last week for a 3-day workshop to define a common approach towards creating net zero certification pathways.
“It’s extremely important that GBCs worldwide align their net zero building certifications with the global emissions reductions goals established by the international community in the climate agreement reached in Paris last December.”
Edward Mazria, Founder and CEO, Architecture 2030
At COP21 in Paris, nearly 200 countries forged an unprecedented agreement to phase out fossil fuel CO2 emissions from the built environment by mid-century. In a rapidly urbanizing world, plans to meet this commitment must focus on urban development and building design to meet zero emissions performance standards. Adding Zero Net Carbon (ZNC) certifications sends a strong signal to the global marketplace and establishes ZNC as standard practice for all new construction and major renovations by 2030.
Two key long-term goals were agreed at the Advancing Net Zero workshop:
- All new buildings and major renovations are built to a ZNC standard starting in 2030, and
- 100% of buildings achieve zero emissions by 2050
The ten national GBCs present at the three-day workshop are taking the lead in meeting these goals as they represent countries with some of the highest projected growth in construction over the next three decades. Certification pathways developed by this group are also intended to lead the way for other GBCs to follow.
Zero Net Carbon Definition
A priority for the workshop attendees was to establish a shared definition for net zero that would form a basis for their certification pathways. Architecture 2030 led the discussion by putting forward the ZNC definition they developed in collaboration with Rocky Mountain Institute and New Buildings Institute.
A ZNC building is defined as:
a highly energy efficient building that produces on-site, or procures, enough carbon-free renewable energy to meet building operations energy consumption annually.
The GBCs committed to align their ZNC definitions and programs to achieve a common carbon goal, one that will drive significant momentum in shifting industry and regulation towards substantial greenhouse gas (GHG) emissions reductions.
Other fundamental principles agreed by the national GBCs include transparency over how the proposed ZNC pathways are to be used to drive improvement in the building sector. Importantly, all the GBC representatives also championed a level of energy efficiency in their planned certifications, and their initial plans include consideration of a combination of on-site and off-site renewable energy, and in some cases, offsets.
Each participating GBC pledged to adopt a ZNC definition and certification program as soon as possible, with a goal of having those in place by the end of 2017. Each GBC is also committed to developing training materials and educational resources.
The workshop also provided a valuable opportunity for the GBCs to collaborate on approaches and offer each other insight on how to accelerate development of their ZNC programs.
“This commitment lays the foundation by creating common guidelines for each of the parties to follow. The GBCs are leading an important effort towards meeting the Paris Agreement by setting a unique path to successfully address the climate crisis.”

Architecture 2030 joins WorldGBC as the lead partner in a new project – Advancing Net Zero – to deliver “net zero” building energy or greenhouse gas emissions (GHG) certification pathways across Green Building Councils (GBCs) worldwide.
At the heart of the Paris Agreement is the “long-term goal” committing almost 200 countries to keep the global average temperature increase to “well below 2°C” above pre-industrial levels .
