Different Guidelines, Different Definitions : Why We Need a Standardised Net Zero Carbon Certification Scheme for Real Estate Investors
Our industry is engaged in an important dialogue to improve sustainability through ESG transparency and industry collaboration. This article is a contribution to this larger conversation and does not necessarily reflect GRESB’s position. Please refer to official GRESB documents for assessment related guidance.
To limit global warming to 1.5°C, the world needs to be carbon neutral by 2050. Real estate investors are racing to capture the business opportunities and mitigate risks in the transition towards a zero-carbon economy. To date, 128 asset managers, representing approximately $43 trillion in assets under management (AUM), are committed to the Net Zero Asset Managers initiative and supporting the goal of net-zero greenhouse gas emissions by 2050 or sooner.
The Importance of Setting an Appropriate Target Boundary
To develop a net-zero carbon target and roadmap, the first and arguably the most critical step is defining the target boundary.
It is essential to allow fair comparison and track progress towards the target. However, real estate investors face unique challenges in scoping and defining the range of emission sources to be included in the target, for example, the need to address indirect Scope 3 emissions through tenant engagement and sometimes short holding period of the assets.
Different Guidelines, Different Definitions
While various organisations have developed definitions and methodologies around net-zero carbon, to date, there is no universal standard of target scopes and boundaries. Listed below are some of the key pledges and frameworks currently operating in the real estate investment industry:
World Green Building Council (WGBC) Net Zero Carbon Buildings Commitment
The Commitment urges businesses, cities, and governments to operate all new buildings at net zero carbon by 2030. All buildings will be net-zero carbon in operation by 2050. The target boundary includes all assets under the entity’s direct control. In the meantime, WGBC Advancing Net Zero also advocates for integrating embodied carbon in the roadmap towards net zero. By 2030, new buildings, renovation and infrastructure should have 40% less embodied carbon and then achieve net-zero embodied carbon by 2050.
UN-convened Net-Zero Asset Owner Alliance
Led by the former Executive Secretary of the United Nations Framework Convention on Climate Change (UNFCCC), Christiana Figueres, the alliance was founded in 2019 at the UN Climate Action Summit. A group of 43 leading global investors, with $6.6 trillion in AUM, committed to decarbonise their portfolio and achieve net-zero by 2050. The framework also comes with engagement targets, financing transition targets, and policy engagement targets.
Net Zero Asset Managers Initiative
Over 120 asset managers committed to supporting decarbonisation towards net-zero by 2050 or sooner and pledged to invest in assets aligned with the goal. The pledge requires signatories to develop investment products in line with net-zero by 2050 and “facilitate increased investment in climate solutions.”
Urban Land Institute (ULI) Greenprint Net-Zero Goal
The ULI Greenprint goal focuses on addressing carbon emissions under its members’ operational control, aiming to reduce greenhouse gas emissions by half by 2030 and achieve net-zero by 2050. The goal references the World Green Building Council definition of net-zero. It encourages members to prioritise energy-efficient and renewable energy opportunities on their journey towards net zero.
Better Building Partnership (BBP) Climate Commitment
BBP represents members of 26 of the world’s largest real estate owners and managers. The coalition published the Climate Change Commitment to align the net-zero carbon pathways for real estate investors. The pledge aims to “deliver net-zero buildings by 2050 incorporating both direct and indirect investments, operational and embodied carbon and Scope 1, 2 and 3 emissions.”
Science-based Targets Initiatives (SBTi) Net Zero Standard
The Science-based Targets Initiatives (SBTi) is founded by CDP, the UN Global Compact (UNGC), the World Resources Institute (WRI) and WWF. The initiative provides methodologies and pathways for businesses to develop decarbonisation targets in line with what “the latest climate science deems necessary to meet the goals of the Paris Agreement”. SBTi is also developing the first global standard to guide companies in setting science-based net-zero carbon targets, which will formally launch in November 2021. In the Net-Zero Criteria Draft for Public Consultation, SBTi discussed the importance of establishing a target boundary that should cover ‘the most material emission sources in the company’s value chain.’
Below is a comparison of the target scoping requirements of various net-zero carbon guidelines:
WGBC Net Zero Carbon Buildings Commitment
Net-Zero Asset Owner Alliance
Net Zero Asset Managers Initiative
ULI Greenprint Net-Zero Goal
BBP Climate Commitment
Mandatory inclusion of Scope 3 emission
In development (embodied carbon only)
2030 and 2050
2025 and 2050
2030 and 2050
2050 and potential interim targets
Signatories to disclose targets and building performance within two years of signing
Members to publish interim targets every five years
Signatories to review interim targets at least every five years and publish TCFD disclosures
ULI to publish collective progress every year
Members to annually disclose progress towards net zero carbon and energy performance
Companies to annually disclose carbon inventory and progress against their published targets
* Remarks: According to the draft net-zero criteria published in Jan 2021.
Apart from industry commitments, governments have also started to develop voluntary and regulatory frameworks in defining net-zero targets, such as the Australian ClimateActive Certification and the Japanese Zero Energy Buildings (ZEB).
However, these regulations are not translatable to other regions. As a result, around the globe, a standardised definition and target-setting framework for net-zero carbon are still lacking in the real estate investment sector.
Real Estate Investors Need a Standardised Net Zero Carbon Certification Scheme
The confusion associated with these competing standards and guidelines has created challenges for businesses when comparing net zero carbon targets in like-for-like terms and has potentially opened doors to greenwashing.
As the ESG landscape currently stands, there is a desperate need for a standardised certification framework to verify companies’ net-zero targets. It is expected that the SBTi Net-Zero Standard would serve as a global certification standard for corporate net zero carbon targets. However, a standard tailored to the real estate sector and especially to investment companies is still awaiting.Longevity Partners develop an ambitious, yet practical net-zero carbon roadmap with our 5-step approach – Measure, Optimise, Generate, Source and Offset.
