Why Taxonomies Matter
A green taxonomy is a classification system that defines which economic activities qualify as environmentally sustainable. Without a taxonomy, terms like "green bond," "sustainable investment," and "ESG-aligned" lack precise meaning, creating risks of greenwashing and market confusion.
The EU Taxonomy Regulation, which entered into force in July 2020, established the global benchmark for this classification exercise. By defining six environmental objectives and establishing technical screening criteria for economic activities, the EU created a framework that is rapidly influencing sustainable finance regulation worldwide. As the GCC states develop their own sustainable finance ecosystems, the question of whether and how to develop regional taxonomies has become urgent.
The EU Taxonomy: The Global Benchmark
Understanding the GCC's emerging frameworks requires first understanding the EU Taxonomy, which sets the standard against which other taxonomies are evaluated:
Six Environmental Objectives
- Climate change mitigation
- Climate change adaptation
- Sustainable use and protection of water and marine resources
- Transition to a circular economy
- Pollution prevention and control
- Protection and restoration of biodiversity and ecosystems
Key Design Principles
- Science-based thresholds: Technical screening criteria are grounded in climate science, using quantitative thresholds (e.g., emissions intensity per unit of output) rather than qualitative descriptions.
- Do No Significant Harm (DNSH): Activities must make a substantial contribution to at least one objective without significantly harming any other objective.
- Minimum safeguards: Activities must comply with minimum social safeguards, including OECD Guidelines, UNGPs, and ILO core conventions.
- Transition activities: The taxonomy includes activities that are not yet zero-carbon but enable the transition, subject to conditions.
The Gas and Nuclear Debate
The EU Taxonomy's treatment of natural gas and nuclear energy has been contentious and is directly relevant to GCC interests. The European Commission's Complementary Delegated Act, published in early 2022, proposes including gas-fired power generation and nuclear energy as transitional activities under specific conditions (gas plants must meet lifecycle emissions thresholds and commit to switching to low-carbon fuels by 2035). This decision has been politically divisive within the EU and is watched closely by GCC gas producers.
UAE: Leading GCC Sustainable Finance Development
The UAE has made the most progress among GCC states in developing a sustainable finance framework:
Abu Dhabi Sustainable Finance Declaration
In 2019, 25 institutions signed the Abu Dhabi Sustainable Finance Declaration, committing to integrate sustainability into financial decision-making. This created momentum for framework development but was a statement of intent rather than a regulatory instrument.
UAE Sustainable Finance Framework
The UAE has been developing a national sustainable finance framework through the UAE Sustainable Finance Working Group, co-chaired by the Central Bank of the UAE (CBUAE), the Securities and Commodities Authority (SCA), the Dubai Financial Services Authority (DFSA), and the Abu Dhabi Global Market (ADGM).
Key elements of the emerging framework include:
| Component | Status (as of March 2022) | Alignment |
|---|---|---|
| Guiding Principles | Published 2020 | ICMA Green Bond Principles, Climate Bonds Standard |
| Green Bond Guidance | Available through ADGM and Nasdaq Dubai | ICMA GBP |
| Taxonomy | Under development | Considering EU Taxonomy alignment with regional adaptation |
| ESG Disclosure | ADX ESG Guide published 2019; ADGM sustainability reporting guidance | GRI, TCFD |
| Green Sukuk | Framework available; several issuances completed | AAOIFI Shariah standards + ICMA GBP |
Green Bond and Sukuk Market
The UAE has established itself as the GCC's leading green bond and sukuk market. Notable issuances include Majid Al Futtaim's $600 million green bond (2019), the first from a GCC corporate, and various sovereign and quasi-sovereign green instruments. The listing of green bonds on Nasdaq Dubai and ADGM provides market infrastructure.
Saudi Arabia: Taxonomy Development Under Vision 2030
Saudi Arabia's sustainable finance development is linked to the broader Vision 2030 economic diversification agenda and the Saudi Green Initiative:
Saudi Central Bank Initiatives
The Saudi Central Bank (SAMA) has been engaging with sustainable finance through its Financial Sector Development Program. SAMA is exploring ESG integration in banking supervision and the development of green lending guidelines.
Capital Market Authority (CMA)
The CMA has been developing ESG disclosure requirements for listed companies on the Saudi Exchange (Tadawul). While not yet mandatory, the trajectory is toward increasingly structured sustainability reporting requirements.
Green Bond Issuance
Saudi Arabia's first green bond, a $750 million issuance by Saudi Electricity Company in 2020, demonstrated market interest and institutional capability. NEOM has signalled plans for green bond financing. The Public Investment Fund (PIF) has incorporated ESG considerations into its investment framework.
Taxonomy Status
Saudi Arabia has not yet published a formal green taxonomy but is understood to be developing one through coordination between SAMA, CMA, and relevant government bodies. The Circular Carbon Economy concept adopted at the G20 level influences the taxonomy approach, with implications for how natural gas and CCS-enabled activities are classified.
Qatar: Building the Foundation
Qatar's sustainable finance ecosystem is at an earlier stage of development compared to the UAE and Saudi Arabia, but foundational elements are in place:
Qatar Central Bank (QCB)
QCB has published ESG guidance for banks and is exploring green finance frameworks. Qatar's banking sector, anchored by institutions such as Qatar National Bank (QNB), Qatar Islamic Bank (QIB), and Commercial Bank of Qatar, has begun incorporating ESG considerations into lending and investment decisions.
Qatar Financial Centre (QFC)
The QFC Regulatory Authority has been developing sustainable finance guidance for entities registered in the QFC. The QFC's role as a platform for international financial institutions operating in Qatar positions it to facilitate green finance market development.
Qatar Stock Exchange (QSE)
The QSE has been promoting ESG disclosure among listed companies, publishing an ESG guide and encouraging adoption of sustainability reporting. QSE joined the Sustainable Stock Exchanges (SSE) Initiative, signalling commitment to market development.
Green Bond Potential
Qatar has significant potential for green bond issuance across several sectors:
- Transport: Doha Metro expansion and public transport investments
- Renewable energy: Al Kharsaah solar plant and future solar capacity
- Green buildings: GSAS-certified construction projects
- Water: Desalination efficiency improvements and water infrastructure
- Waste management: Waste-to-energy and recycling infrastructure
Key Design Questions for GCC Taxonomies
As GCC states develop their taxonomies, several design questions are particularly important and reflect regional specificities:
1. Treatment of Natural Gas
This is the defining question for any GCC taxonomy. Natural gas is the backbone of the GCC energy system and a major export commodity. A taxonomy that excludes gas entirely would render most GCC economic activity "taxonomy-ineligible," undermining the framework's utility. A taxonomy that includes unabated gas without conditions would lack credibility internationally. The challenge is defining credible transitional criteria — such as emissions intensity thresholds, CCS requirements, and sunset clauses — that reflect the GCC's energy transition reality while maintaining environmental integrity.
2. CCS-Enabled Activities
Given the GCC's strategic emphasis on CCS as a decarbonisation pathway, taxonomies must address how CCS-enabled activities are classified. Should a gas power plant with 90% carbon capture qualify as "green"? What about blue hydrogen? The EU Taxonomy's approach to these questions provides one model, but GCC taxonomies may take different positions reflecting regional priorities.
3. Desalination
Seawater desalination is essential for water security in the GCC but is energy-intensive and generates environmental impacts (brine discharge, marine ecosystem effects). A GCC taxonomy must address whether and how desalination qualifies as a sustainable activity, potentially distinguishing between conventional and renewable-powered desalination, or between thermal and reverse osmosis technologies based on energy efficiency.
4. Cooling
District cooling, building cooling systems, and thermal energy storage are critical for liveability in the Gulf's extreme climate. Cooling is responsible for a large share of electricity demand and associated emissions. Taxonomy treatment of cooling technologies and efficiency standards is important for directing green finance toward climate adaptation infrastructure.
5. Interoperability with EU Taxonomy
GCC issuers seeking European investors and GCC financial centres positioning as global sustainable finance hubs need interoperability with the EU Taxonomy. Complete replication is neither appropriate nor politically feasible, but sufficient alignment to enable cross-recognition of green labels would expand the investable universe for both regions.
Practical Implications for GCC Companies
Companies operating in the GCC should prepare for the arrival of green taxonomies, regardless of the specific timeline:
Data Readiness
Taxonomy eligibility and alignment assessments require granular data on economic activities, revenues, capital expenditure, and operating expenditure, broken down by activity type. Companies should begin building the data architecture needed for taxonomy reporting.
Asset-Level Assessment
Companies with diverse asset portfolios (real estate developers, industrial conglomerates, banks) should conduct preliminary assessments of which assets and activities are likely to qualify under emerging taxonomy criteria.
Green Finance Strategy
Organisations planning capital raises should consider whether a green or sustainability-linked format is feasible and commercially advantageous. Green bonds typically achieve a "greenium" (lower yield) of 2-10 basis points, which improves with the credibility and specificity of the green framework.
ESG Disclosure
Taxonomy reporting builds on ESG disclosure. Companies not yet reporting sustainability data should begin with established frameworks (GRI, TCFD) as the foundation for future taxonomy-aligned reporting.
The Path Forward
The development of GCC green taxonomies is inevitable but will take time. The EU's taxonomy development consumed over five years from the establishment of the Technical Expert Group to the publication of delegated acts, and remains incomplete. GCC states can learn from the EU process and from emerging taxonomies in ASEAN, China, and other jurisdictions.
The most important principle is that GCC taxonomies should be credible enough to be taken seriously by international investors while practical enough to reflect the region's economic reality. A taxonomy that is too lax undermines trust; one that is too strict renders itself irrelevant.
