Across 2023, global investment in grid and industrial energy upgrades kept momentum, with US$2.1 billion flowing into grid scale battery storage and US$610 billion into renewable energy. At the same time, the emissions picture for defense related manufacturing and base operations connects to harder-to-abate sectors where industry accounts for 36% of global energy related CO2 emissions and food systems add another 10% of global GHG. These contrasts raise a practical question for defense planners and contractors alike which decarbonization moves actually translate into reliability, procurement decisions, and measurable progress.
Key Takeaways
- 4,700+ megawatts of energy storage capacity were deployed globally in 2023 to support electricity reliability as renewables scale (U.S. DOE defines utility-scale battery storage as a key enabler of decarbonization and grid flexibility).
- 1,574 gigawatts of renewable power capacity was added globally in 2023, increasing the share of low-carbon generation used by industry and government (IEA).
- 10% of global GHG emissions are estimated to come from food systems, relevant to procurement and base operations (IPCC AR6 WGIII).
- 67% of public agencies in a 2023 global survey reported having green procurement policies, influencing how defense contractors bid for lower-carbon goods and services (OECD survey report).

- 1,600+ companies participate in Science Based Targets initiative (SBTi) across sectors as of 2024, increasing adoption of near-term emissions targets among suppliers (SBTi).
- 64% of organizations reported implementing energy efficiency measures to meet net-zero targets in 2023 (IEA).
- GHG Protocol Scope 3 categories include 15 categories of value chain emissions, which many defense contractors must quantify for supply chain decarbonization (GHG Protocol Corporate Value Chain).
- ISO 14064 provides a framework for quantifying and verifying GHG emissions and removals, enabling consistent defense contractor reporting (ISO).
- EU ETS allocations cap emissions from stationary installations; Phase 4 applies a linear reduction factor of 4.2% per year of the cap (European Commission).
- Global demand for sustainable aviation fuel (SAF) reached about 0.3 million metric tons in 2023, a driver for defense aviation fuel transition planning (IEA).
- The EU CBAM includes an explicit carbon price equivalent calculation, with transitional phase starting in 2023 and full coverage from 2026, altering costs of imported defense materials (European Commission).
- For U.S. agencies, the Energy Conservation Investment Program (ECIP) can finance retrofits through appropriations; authorized funding totals exceed US$200 million annually in recent Congressional budgets (U.S. OMB).

02
1.4% of global greenhouse-gas emissions were estimated to come from fluorinated gases (F-gases) in 2021 — relevant because defense platforms and industrial refrigeration/propellants can include F-gases.
03
20% of global industrial CO2 emissions are from iron and steel, 13% from chemicals, and 10% from cement (industry process emissions, latest data as summarized by Ember) — highlights material chokepoints for defense supply chains.
04
Russia’s and EU combined emissions trading coverage is tied to the EU ETS cap system in which Phase 4 runs from 2021–2030 with annual linear reduction; the cap reduction factor is 4.2% per year (linear reduction) — used for long-run planning for ETS-regulated defense-related stationary sources in the EU.
05

Interpretation
Emissions & Decarbonization Interpretation
Emissions and decarbonization in the defense sector matter because industry accounts for 36% of global energy-related CO2 in 2022 and major process chokepoints such as iron and steel at 20% and chemicals at 13% drive industrial CO2, so cutting these emissions plus F gases that made up 1.4% of global greenhouse gases in 2021 can meaningfully accelerate the kind of reductions needed alongside policies like the EU ETS Phase 4 annual 4.2% linear cap decline.
