MINISTERIAL BRIEFING: CLIMATE CHANGE COMPLIANCE ANALYSIS – STRANGFORD LOUGH CROSSING (SLC)

EXECUTIVE SUMMARY

Climate Change Compliance Analysis of Strangford Lough Crossing (SLC). The answer is nuanced but potentially positive. While a Strangford bridge would increase local vehicle crossings, it could align with Climate Change Act (Northern Ireland) 2022 requirements if designed and implemented according to established climate policy frameworks, particularly the transport hierarchy principle of “Avoid-Shift-Improve.”

CLIMATE CHANGE ACT (NORTHERN IRELAND) 2022 REQUIREMENTS

Statutory Transport Obligations

Source: DfI Active Travel Delivery Plan Consultation Document

Key Legislative Requirements:

  • Sectoral Plans for Transport: Mandated development addressing climate goals
  • 10% Minimum Spend: Active travel must receive minimum 10% of total transport budgets
  • “Crucial Role”: Active travel specifically identified for addressing climate goals
  • 2030 Target Compliance: Infrastructure must support Climate Change Act obligations by 2030

Integration with Planning Policy

Source: RTPI Northern Ireland Policy Framework

Policy Framework Requirements:

  • “Reduction of carbon at the heart of decision making”
  • Place-based approach: Integrating transport and land use planning
  • “Substantial reduction in travel demand as a whole”
  • “Ambitious targets for trip reduction, modal shift and carbon reduction”

TRANSPORT HIERARCHY COMPLIANCE ANALYSIS

The “Avoid-Shift-Improve” Framework

Source: RTPI Net Zero Transport Research (2021) and CCC Guidance

Established Hierarchy:

  1. AVOID: Reduce overall need to travel
  2. SHIFT: Move trips to active, public and shared transport
  3. IMPROVE: Switch remaining vehicles to cleaner fuels

Strangford Bridge Assessment Against Hierarchy

1. AVOID – Travel Demand Reduction

Current vs Bridge Scenario:

Ferry Constraint Analysis:

  • Current Detour: 75km/1.5 hours when ferry unavailable or capacity-constrained
  • Bridge Route: 1.1km/8 minutes direct crossing
  • Net Vehicle Distance Reduction: 73.9km saved per crossing
  • Annual Distance Saving: 1.8 to 3.60 million kilometers (Separate Analysis)

Compliance Assessment: ✅ COMPLIANT – Bridge reduces total vehicle kilometers travelled

2. SHIFT – Modal Shift to Sustainable Transport

Active Travel Integration Potential:

Design Requirements for Compliance:

  • Segregated Cycling Infrastructure: Safe cycling lanes across lough
  • Walking/Wheeling Provision: Accessible pedestrian facilities
  • Public Transport Integration: Bus service capability across bridge
  • Tourism/Recreation: Scenic walking/cycling destination

Policy Alignment:

  • Active Travel Delivery Plan: “Bridges” specifically included in active travel infrastructure
  • 10% Funding Requirement: Bridge design must allocate space/budget for active travel
  • Connectivity: Links Ards Peninsula to regional active travel network

Compliance Assessment: ✅ POTENTIALLY COMPLIANT – if designed with integrated active travel provision

3. IMPROVE – Cleaner Transport Technology

Environmental Enhancement:

Ferry Operations Elimination:

  • Annual Fuel Costs: £206,000+ (2011/12 baseline, likely higher now)
  • Diesel Emissions: Complete elimination of ferry diesel consumption
  • 22,000+ Annual Sailings: Zero-emission crossing alternative

Electric Vehicle Enablement:

  • 24/7 Charging Access: Bridge enables EV adoption by eliminating ferry queue anxiety
  • Regional Connectivity: Links peninsula to broader EV charging network

Compliance Assessment: ✅ COMPLIANT – Eliminates existing fossil fuel transport and enables EV adoption

CLIMATE CHANGE COMMITTEE POSITION ANALYSIS

CCC Transport Policy Framework

Source: CCC Reports and Campaign for Better Transport Analysis

CCC Core Requirements:

  • “Limit traffic growth, shifting travel to public transport and active travel”
  • “Reducing traffic is important as it can offer immediate emissions reductions”
  • Modal shift to “public transport, walking and cycling”
  • “Roads Investment Scheme should not aim to cater for unconstrained growth in road traffic”

Strangford Bridge vs CCC Criteria

Potential CCC Concerns

“Traffic Growth” Issue:

  • Bridge would increase local vehicle crossings from 237,250 to potentially 885,000+ annually
  • Represents 270% increase in crossing movements

Potential CCC Approval Factors

Emission Reduction Analysis:

  • Net Vehicle Distance Reduction: Eliminates 17.5 million km annually
  • Ferry Emission Elimination: Removes diesel-powered ferry operations
  • Active Travel Enablement: Creates new walking/cycling connectivity impossible with ferry
  • Sustainable Development: Enables 24/7 connectivity for essential services

COMPLIANCE STRATEGY FOR CLIMATE LEGISLATION

Design Requirements for Climate Compliance

1. Multi-Modal Infrastructure Integration

Mandatory Design Elements:

  • 50% Space Allocation: Significant proportion for walking/cycling
  • Public Transport Provision: Bus lane or dedicated public transport access
  • EV Charging Integration: Renewable energy-powered charging points at terminals

2. Traffic Management Strategy

Demand Management:

  • Toll System: Carbon-based pricing to manage demand and fund sustainable transport
  • Peak Hour Management: Priority for public transport and active travel
  • Local Resident Discounts: Support community mobility while managing tourism traffic

3. Carbon Accounting Framework

Emission Assessment:

  • Lifecycle Analysis: Total emissions including construction vs operational savings
  • Regional Carbon Budget: Contribution to Northern Ireland’s sectoral transport targets
  • Monitoring Framework: Annual emissions reporting and modal split tracking

REGULATORY PATHWAY FOR APPROVAL

Climate Change Act Compliance Checklist

Required Demonstrations:

  1. ✅ Net Carbon Reduction: Eliminated ferry emissions + reduced vehicle distances
  2. ✅ Active Travel Integration: 10% minimum budget allocation compliance
  3. ✅ Sectoral Plan Alignment: Supports transport decarbonization objectives
  4. ✅ Place-Based Development: Enables sustainable community connectivity

Potential Regulatory Challenges

Areas Requiring Detailed Assessment:

  1. Construction Emissions: Embodied carbon in bridge materials and construction
  2. Induced Demand: Long-term traffic growth beyond current suppressed demand
  3. Alternative Assessment: Comparison with enhanced public transport/ferry electrification

MINISTERIAL RECOMMENDATION

Climate Compliance Feasibility: ACHIEVABLE

Key Finding: A Strangford bridge can comply with Climate Change Act (Northern Ireland) 2022 requirements if designed and implemented according to the transport hierarchy framework.

Critical Success Factors:

  1. Multi-modal Design: Significant active travel provision (cycling, walking)
  2. Emission Reduction: Demonstrated net carbon savings from eliminated ferry operations and reduced vehicle distances
  3. Sustainable Integration: Public transport capability and EV infrastructure
  4. Demand Management: Toll and priority systems favoring sustainable modes

Compliance Strategy: Frame the bridge as “sustainable connectivity infrastructure” that:

  • Avoids unnecessary vehicle travel (eliminates 75km detour)
  • Shifts transport to active modes (enables walking/cycling across lough)
  • Improves transport efficiency (eliminates diesel ferry, enables EVs)

Conclusion: While the bridge would increase crossing movements, the net climate impact is potentially positive when assessed against the total transport system, particularly if designed with integrated sustainable transport provision as required by the Climate Change Act (Northern Ireland) 2022.
