The Six Environmental Objectives
The EU Taxonomy is organised around six environmental objectives — each representing a key area of environmental sustainability. Economic activities must Substantially Contribute to at least one objective while not significantly harming any other. Here is what each objective covers and which sectors are most affected.
The EU Taxonomy is organised around six environmental objectives — each representing a key area of environmental sustainability. Objective 1 — Climate Change Mitigation: Economic activities that Substantially Contribute to stabilising GHG concentrations in the atmosphere consistent with the Paris Agreement.
Objectives 1 and 2 — climate change
Objective 1 — Climate Change Mitigation: Economic activities that Substantially Contribute to stabilising GHG concentrations in the atmosphere consistent with the Paris Agreement. This is the most developed objective — Technical Screening Criteria cover electricity generation, manufacturing, transport, buildings, water, and agriculture.
Key Substantial Contribution threshold examples: electricity generation below 100g CO2e/kWh; cement production below 0.722t CO2/t clinker; new buildings meeting near-zero energy building standards; passenger cars with zero direct emissions.
Objective 2 — Climate Change Adaptation: Activities that Substantially Contribute to reducing the adverse impacts of climate change on the activity itself, on people, nature, or assets. TSC for Objective 2 require a physical climate risk assessment demonstrating the activity is resilient to projected climate change over its lifetime.
Objective 2 is cross-cutting — almost any activity can qualify if it incorporates climate adaptation measures. Infrastructure designed for 50-year flood return periods, buildings with passive cooling, and water systems designed for drought resilience are common examples.
Objectives 3, 4, and 5 — environment
Objective 3 — Sustainable Use and Protection of Water and Marine Resources: Activities that Substantially Contribute to good water status under the EU Water Framework Directive, or to marine ecosystem health. TSC cover water treatment, sustainable aquaculture, and water-efficient irrigation.
Objective 4 — Transition to a Circular Economy: Activities that Substantially Contribute to reducing waste generation, increasing recycling and reuse, or extending product lifetimes. TSC cover waste management, repair services, remanufacturing, and products designed for disassembly.
Objective 5 — Pollution Prevention and Control: Activities that Substantially Contribute to preventing or reducing pollution of air, water, or soil — beyond regulatory compliance. TSC cover pollution monitoring, environmental remediation, and manufacturing activities adopting best available techniques.
These three objectives have less developed TSC than climate — many sectors lack applicable TSC entirely, resulting in zero eligibility for objectives 3–5 even for genuinely sustainable activities.
Objective 6 — biodiversity
Objective 6 — Protection and Restoration of Biodiversity and Ecosystems: Activities that Substantially Contribute to protecting, conserving, or restoring biodiversity and ecosystem services — including habitats, species, and natural processes.
Objective 6 TSC cover: nature-based solutions (wetland restoration, rewilding, urban greening); sustainable forestry meeting FSC or PEFC standards; organic farming; conservation activities; and ecological restoration projects.
For most industrial companies, Objective 6 Substantial Contribution eligibility is low — few conventional business activities qualify. Objective 6 is most relevant for: land management companies; forestry and paper producers; agricultural businesses transitioning to regenerative practices; and conservation finance vehicles.
The DNSH test for Objective 6 (no significant harm to biodiversity) is relevant to virtually all companies with physical operations — site-level proximity to protected areas must be assessed regardless of whether Objective 6 Substantial Contribution is claimed.
Frequently asked questions
Can an activity Substantially Contribute to more than one objective?
Yes — some activities contribute to multiple objectives simultaneously. A wetland restoration project can Substantially Contribute to both Objective 2 (Adaptation — flood protection) and Objective 6 (Biodiversity — habitat restoration). Disclose the primary objective but note contributions to additional objectives.
Why do so many companies show zero alignment for Objectives 3–6?
Two reasons: TSC coverage gaps (many sectors have no applicable TSC for objectives 3–6 yet) and DNSH failure (activities that meet Objective 1 TSC may fail Objective 6 DNSH). The Commission is expanding TSC coverage annually — alignment for objectives 3–6 is expected to grow as new activities are added.
Is there a minimum alignment percentage required?
No — the EU Taxonomy does not set a minimum alignment threshold. Companies must calculate and disclose their alignment accurately, whatever the result. Zero alignment disclosed transparently is acceptable; inflated alignment is greenwashing. The Taxonomy is a transparency framework, not a minimum performance standard.
