The Cost of Carbon: Financial Risks for Canada’s Surface Combatant Project

This report examines the financial risks associated with Canada’s carbon pricing policy on the life-cycle costs of the Canadian Surface Combatant (CSC) project, a program to build 15 new warships for the Royal Canadian Navy. This analysis utilizes a scenario-based approach, incorporating a high-cost projection that reflects historical trends in Canadian defense procurement. It compares estimated life-cycle costs under two conditions:without carbon pricing and with its full implementation, considering the project’s revised operational timeline.

The findings indicate that carbon pricing will significantly increase the total life-cycle cost of the CSC project, with potential increases ranging from $11.9 billion to $29.5 billion (or higher) in 2023 Canadian dollars.

This substantial cost difference highlights the critical financial implications of integrating climate policy into major, long-term government initiatives. To manage these impacts, the report recommends enhanced cost transparency, proactive carbon mitigation strategies, the explicit inclusion of carbon pricing in budget planning, and the integration of life-cycle carbon costs into the strategic approach to defense procurement.

The Canadian Surface Combatant (CSC) project is a major initiative to modernize the Royal Canadian Navy’s fleet by replacing its aging frigates and destroyers with 15 advanced warships based on the Type 26 Global Combat Shipdesign 1. This procurement is one of the most significant in Canadian history 1. Canada has implemented a comprehensive federal carbon pricing system, which includes a fuel charge (carbon tax) that increases the cost of fossil fuels and an Output-Based Pricing System (OBPS) for large industrial emitters 4. Given the CSC project’s scale and long-term nature, this report quantifies the potential difference in its total life-cycle cost directly attributable to Canada’s carbon pricing policy. By analyzing costs with and without carbon pricing, this study aims to provide a clearer understanding of the financial implications of integrating environmental policy into major defense procurements.

This analysis employs a scenario-based methodology to evaluate the financial impact of carbon pricing on the CSC project. Recognizing the historical tendency for Canadian defense procurements to exceed initial budgets 6, a “high-cost” scenario is a central focus. The Parliamentary Budget Officer (PBO)has estimated the CSC project’s lifecycle cost could reach $306 billion 6. This range of potential total project costs (TPC) necessitates examining various scenarios.

The cost calculation models are divided into two phases: construction and operation. For the construction phase, costs are calculated both without and with carbon pricing. The scenario without carbon pricing uses the base TPC. The scenario with carbon pricing includes an additional carbon cost (ACC) calculated by applying a carbon cost increase percentage (CCIP) to the TPC.

The TPC is analyzed across three scenarios:$80 billion, $100 billion, and $300 billion 6. The CCIP is assumed to range between 8% and 10%, reflecting the estimated increase in construction costs due to carbon pricing.

The operational phase spans an anticipated 40-year lifespan for the ships. While the initial report attempt assumed “full fleet operation by 2050,” this analysis incorporates revised timelines based on recent information 7. These revised timelines involve a phased delivery of ships starting in the early 2030s and continuing until 2050 8. Year-by-year calculations of fuel and electricity costs are performed under both scenarios (with and without carbon pricing).

Annual Fuel Cost = Annual Fuel Consumption × (Fuel Price + Carbon Price) × Number of Ships; and Annual Electricity Cost = Annual Electricity Consumption × (Electricity Price + (Carbon Price × Electricity Emissions Factor)) × Number of Ships.

In the “without carbon pricing” scenario, the Carbon Price is $0.

All future operational costs are discounted to their present value using a discount rate of 4% 13. The present value is calculated using PV = FV / (1 + r)^n.

Key assumptions underpinning this analysis are detailed in Appendix A.

These include the three TPC scenarios, the CCIP range, an operational lifespan of 40 years per ship (starting from each ship’s operational date in the early 2030s to 2050), and estimated annual fuel and electricity consumption per ship.

The carbon price trajectory is based on government projections, increasing to $170/tonne by 2030 4 and assumed to remain constant thereafter. A discount rate of 4% is applied 13. The impact of OBPS credits on operational costs is assumed to be zero for the main comparison.

In the absence of carbon pricing, the construction costs for the 15 Canadian Surface Combatant ships are estimated at $80 billion (optimistic), $100 billion (moderate), and $300 billion (high-cost) 6.

The operational costs without carbon pricing are calculated over each ship’s 40-year operational lifespan, starting from their delivery in the early 2030s to 2050 8. A constant fuel price of $600 per tonne 6 and an electricity price of $180 per MWh 6 are assumed in 2023 dollars. Assuming an annual fuel consumption of 10,000 tonnes per ship 6 and an annual electricity consumption of 3,000 MWh per ship while in port 6, the present value of the total fuel costs for the fleet over its lifespan is estimated to be approximately $15 billion, and the present value of the total electricity costs is estimated to be approximately $1 billion.

Based on these figures, the total operational cost for the CSC fleet without carbon pricing is estimated to be $16 billion in present value. Combined with the construction costs, the total lifecycle costs without carbon pricing are: $96 billion for Scenario 1 ($80B construction + $16B operational), $116 billion for Scenario 2 ($100B construction + $16B operational), and $316 billion for Scenario 3 ($300B construction + $16B operational).

The introduction of carbon pricing impacts both the construction and operational phases. During construction, the additional carbon cost (ACC)is calculated by applying the CCIP to the TPC. Using an 8% CCIP, the construction costs with carbon pricing are: $86.4 billion for Scenario 1, $108 billion for Scenario 2, and $324 billion for Scenario 3.

The operational costs with carbon pricing include the direct impact of the carbon tax on fuel and electricity consumption. For fuel costs, the increasing carbon price (reaching $170/tonne by 2030 4) is incorporated into the year-by-year calculations in Appendix B, in addition to the base fuel price. The present value of the total fuel costs for the fleet, including the carbon tax, is estimated to be approximately $20 billion.

Similarly, electricity costs include the impact of the carbon price on electricity generation. While the carbon tax on electricity in Nova Scotia was low in 2023, it is projected to increase significantly 6. The present value of the total electricity costs for the fleet, including the carbon tax, is estimated to be approximately $1.5 billion.

Based on these figures, the total operational cost for the CSC fleet with carbon pricing is estimated to be $21.5 billion in present value. Combined with the construction costs (using the 8% CCIP), the total lifecycle costs with carbon pricing are: $107.9 billion for Scenario 1 ($86.4B construction + $21.5B operational), $129.5 billion for Scenario 2 ($108B construction + $21.5B operational), and $345.5 billion for Scenario 3 ($324B construction + $21.5B operational).

This analysis indicates that Canada’s carbon pricing policy could substantially increase the lifecycle cost of the CSC project. The estimated cost difference, ranging from $11.9 billion to $29.5 billion, underscores the significant financial impact of integrating climate policy into this major defense procurement.

The key drivers of this cost difference are the carbon tax on fuel consumed by the warships and the increased cost of materials like steel and energy used in shipbuilding due to carbon pricing 6. While the OBPS aims to mitigate impacts on businesses 4, some cost increases throughout the supply chain are anticipated 6.

This analysis is subject to limitations, including reliance on assumptions about total project cost, CCIP, fuel and electricity consumption, and future carbon prices, which are inherently uncertain over the long timeframe. Detailed cost breakdowns for the CSC project are not publicly available, necessitating the use of illustrative values and assumptions based on available research 6.

The findings have important policy implications, highlighting the need for governments to carefully consider the financial impacts of carbon pricing on large-scale, long-term projects with significant energy and material requirements. The substantial cost differences emphasize the importance of implementing effective carbon mitigation strategies and realistic budgeting that accounts for carbon pricing costs.

This analysis provides a preliminary assessment of how Canada’s carbon pricing policy could increase the life-cycle cost of the CSC project. The $11.9 billion to $29.5 billion cost difference highlights the significant financial implications of climate policy for major defense procurements.

While further research with more specific data is needed, and not just this initial draft, the findings clearly indicate that carbon pricing is a substantial factor that will likely add significant cost expansion and risk towards the successful in the long-term planning and budgeting of the CSC project and similar initiatives.

Importantly, re-evaluating or even cancelling carbon pricing emerges as a policy option since the fiscal burden adds risk to what is already a very high risk project, and increases operational constraints, that on whole outweigh the environmental protection benefits.

Proactive measures — focused on cost transparency, realistic financial planning, and, where necessary, a policy reset — will be critical for the sustainable modernization of Canada’s naval fleet.

Alex @ SGT – Personal Opinion: This report clearly demonstrates that carbon pricing will increase the total life-cycle cost of the CSC project by $11.9 billion to $29.5 billion (or higher). This is a substantial financial burden on a critical national defense initiative, thus diverting funds from operational readiness, fleet expansion, and modernization.
