Portfolio climate alignment

Portfolio climate alignment uses a defined forward-looking metric to assess whether holdings, loans or underwriting activities are moving toward a stated climate pathway, with the method, benchmark, time horizon and weighting rule clearly disclosed.

What is portfolio climate alignment?

Portfolio climate alignment tests holdings, loans or underwriting against a stated climate pathway. TCFD Guidance section C.4 covers binary target measurement, benchmark divergence and implied temperature rise. These show target coverage, distance from a pathway or a modelled temperature score. This is not a generic investment-policy review.

Why does portfolio climate alignment matter to you?

Asset owners and lenders use results to set targets, monitor holdings and choose engagement priorities. Under SBTi criterion FI-C17.3, institutions report separate temperature scores for Scope 1 and 2, and for Scope 1, 2 and 3. They also state the scenario, weighting rule, data source, public-target coverage and default-score share.

How does portfolio climate alignment work?

Choose the metric and weighting rule. For target coverage, count or weight holdings with qualifying targets. For divergence or temperature scores, choose the pathway, sectors, scopes and time horizon, compare each holding with the benchmark, then aggregate. GFANZ's framework sets out nine design judgements.

What mistakes should you avoid?

  • Calling a portfolio aligned without naming the pathway, year and metric.
  • Comparing results built with different scopes, sector benchmarks or weighting rules.
  • Treating a target as an achieved emissions reduction.
  • Hiding holdings that use defaults or lack forward-looking data.

Is portfolio climate alignment the same as a portfolio carbon footprint?

No. A carbon footprint measures attributed emissions at a date. Alignment tests a projected path against a climate benchmark.

Does an aligned score prove that a portfolio is Paris-aligned?

No. The result applies only to the stated method and inputs. Record the benchmark, model version, calculation date, coverage and assumptions.

What should you send when an investor asks for portfolio alignment?

Send the result, holdings covered, date, pathway, scopes, metric, weighting formula, target coverage, default-data share, exclusions and company-level inputs.

Example

Suppose a lender has four equal-sized JPY 250 million loans to hypothetical plastics moulders in Japan, for a total portfolio of JPY 1 billion. Two borrowers have validated 1.5°C-aligned targets, one has an unvalidated target and one has no target.

Using GFANZ's binary target measurement, the target-covered share by borrower count is 2 qualifying borrowers / 4 borrowers x 100 = 50%. Because every loan has the same value, a separately disclosed loan-value weighting also gives (JPY 500 million / JPY 1 billion) x 100 = 50%.

This 50% result measures target coverage under the stated rule. It does not show the borrowers' benchmark divergence, implied temperature rise or actual emissions reductions.

Related terms

Implied temperature rise

Implied temperature rise is a modelled estimate, expressed in degrees Celsius, of the warming associated with an entity's or portfolio's projected emissions path relative to a chosen climate benchmark.

Portfolio carbon footprint

A portfolio carbon footprint sums the GHG emissions attributed to investments and usually divides that total by portfolio value to report tonnes of carbon dioxide equivalent per million invested.

Financed emissions

Financed emissions are the share of a borrower's or investee's gross GHG emissions allocated to a bank, fund or asset owner through the loans and investments it holds.

Science-Based Targets

A science-based target states how quickly a company will cut greenhouse gas emissions in line with a climate pathway accepted by the Science Based Targets initiative (SBTi), using a defined boundary, base year and target year.
