Most people focus on direct emissions from energy and transport. Financed emissions — the emissions linked to where your money is held and invested — are less visible, but for many US households they are comparable in scale to direct lifestyle emissions.
What are financed emissions
Financed emissions represent the share of a company’s greenhouse gas emissions attributable to its capital providers — banks that lend to it, pension funds that hold its stock, index funds that track indices it belongs to.
The concept is defined in the GHG Protocol’s guidance on financial sector accounting and referenced in IPCC AR6 discussions on financial flows and climate alignment. The basic logic: capital enables activity. Capital allocated to fossil fuel extraction enables extraction. The emissions from that extraction are partly attributable to the capital providers.
For individuals, the relevant capital pools are savings accounts, checking accounts, pension funds, 401(k) allocations, ETFs, and index funds.
Why this is larger than most people expect
The IEA’s Net Zero by 2050 roadmap reports that continued fossil fuel investment is inconsistent with 1.5°C pathways. Major US banks remain among the largest financiers of fossil fuel projects globally, according to annual Banking on Climate Chaos reports compiled from public financial disclosures.
Studies applying GHG Protocol financed emissions methodology to average US household portfolios suggest that shifting pension and investment allocations away from fossil-intensive assets can reduce attributed emissions by 0.5–2.0 tCO₂e per year, depending on portfolio size and composition.
That range is comparable to eliminating several domestic flights or switching from a petrol car to an EV.
How financed emissions vary by investment type
| Investment type | Relative carbon intensity | Notes |
|---|---|---|
| Fossil fuel sector stocks | Very high | Direct exposure to reserves and extraction |
| Broad S&P 500 index fund | Medium | Includes fossil fuel companies at market weight |
| ESG-screened equity fund | Lower | Screens vary significantly by fund |
| Fossil-free or climate-aligned fund | Significantly lower | Explicit exclusion criteria |
| Savings at fossil-fuel-financing bank | Medium | Indirect via lending book |
| Savings at fossil-free bank | Lower | Lending policy restricts fossil fuel exposure |

The measurement challenge
Financed emissions are harder to measure precisely than direct emissions for two reasons. First, portfolio data is often incomplete or delayed. Second, attribution methodology — how much of a company’s emissions to assign to each investor — is not fully standardised, though the GHG Protocol and PCAF (Partnership for Carbon Accounting Financials) have established working frameworks.
What you can evaluate today, without complex modelling, is your bank’s lending policy and your fund’s fossil fuel exposure. Most major fund providers publish carbon footprint data for their ETFs. Most banks publish climate commitment statements, though the quality of these varies significantly.
What this means in practice
For most US households, three decisions determine financed emissions most directly: which bank holds your savings and checking accounts, which funds hold your retirement savings, and whether your investment portfolio is screened for fossil fuel exposure.
Switching banks is straightforward, for switching pension fund allocations requires checking what options your employer’s plan offers — many now include ESG-screened alternatives. Finally, switching index funds within a self-directed account is typically a single transaction.
None of these changes requires spending money. They require reallocating existing capital.
Where financed emissions sit in your total footprint
Financed emissions are not yet standard in most personal carbon calculators, including Decarb’s current Phase 0 calculator. We include them here because they are material and because the IPCC identifies financial flows as a critical lever for system-level decarbonisation.
For households with significant retirement savings or investment portfolios, financed emissions may exceed direct lifestyle emissions in total attributed tons. This is particularly true for higher-income households where investment portfolios are larger relative to direct consumption.
