Novel Entities

Planetary Boundary 9

Boundary Status

Status: Boundary transgressed
Control Variable: Not yet fully quantified (complexity: >350,000 chemicals registered)
Qualitative Assessment: Pollution from plastics, persistent organic pollutants (POPs), endocrine disruptors, heavy metals, nanomaterials, GMOs exceeds safe limits

Scientific Basis: Novel entities include synthetic chemicals, plastics, GMOs, nanomaterials, and other anthropogenic substances that have no natural analogs. Many persist in the environment, bioaccumulate, and cause chronic health and ecosystem harm. Microplastics now found in human blood, placenta, and every ecosystem on Earth.

Business Relevance

Key Novel Entity Categories

1. Plastics

• Scale: 460 Mt produced annually (2019); 8 Mt enter oceans/year
• Business Impact: Extended Producer Responsibility (EPR), plastic taxes, single-use bans

2. Persistent Organic Pollutants (POPs)

• Examples: PCBs, dioxins, PFAS ("forever chemicals")
• Business Impact: Product bans, contamination liability, remediation costs

3. Heavy Metals

• Examples: Lead, mercury, cadmium, arsenic
• Business Impact: Exposure limits, electronics recycling mandates (e-waste)

4. Endocrine Disruptors

• Examples: BPA, phthalates, parabens
• Business Impact: Chemical restrictions in consumer products

5. Nanomaterials

• Examples: Carbon nanotubes, nanosilver, titanium dioxide nanoparticles
• Business Impact: Emerging regulation (EU REACH nanomaterials annex)

Key Standards & Frameworks

Disclosure Standards

• EU ESRS E2 — Pollution (covers chemicals, plastics, hazardous substances)
• GRI 306 — Waste (includes hazardous waste)
• GRI 301 — Materials (includes recycled content)

Chemical Regulation

• EU REACH — Registration, Evaluation, Authorization of Chemicals
• Stockholm Convention on POPs — Global treaty banning persistent organic pollutants
• Basel Convention — Hazardous waste transboundary movement
• Rotterdam Convention — Hazardous chemical trade (PIC procedure)

Plastics Regulation

• EU Single-Use Plastics Directive (2019) — Bans on SUP items
• UN Plastics Treaty Negotiations — Global plastics agreement (in progress)
• EU Packaging and Packaging Waste Regulation (PPWR) — Mandatory recycled content, reuse targets

Recommended Metrics

Plastics

• Plastic Packaging Used: Tonnes per year
• Recycled Content: % of packaging from recycled materials
• Single-Use Plastic Elimination: Tonnes reduced
• Plastic Footprint: Tonnes leaked to environment

Chemicals

• Substances of Concern (SoC): Number of chemicals on restriction lists used
• REACH Compliance: % of chemicals pre-registered
• Chemical Intensity: kg chemicals used per unit output

Hazardous Waste

• Hazardous Waste Generated: Tonnes per year
• % Safely Disposed: Compliant disposal/treatment
• E-waste Recycling Rate: % of electronics responsibly recycled

Circular Economy Approaches

Design Strategies:

• Eliminate: Phase out unnecessary chemicals and plastics
• Substitute: Replace hazardous substances with safer alternatives
• Reduce: Minimize material use
• Reuse: Design for multiple lifecycles
• Recycle: Close material loops
