Portfolio Decarbonisation Reference Objective

Sovereign bonds

Net zero objectives for sovereign assets should be distinct and not aggregated with corporate asset objectives to avoid double counting. This approach also acknowledges the structural differences when it comes to investors’ engagement with corporates and sovereign entities.

For further detail, references and citations, investors can revert to the IIGCC’s Sovereign Bonds and Country Pathways discussion paper and target setting guidance.

Defined as CO2e absolute and intensity emissions reduction objective.

A five year stocktake is recommended to facilitate assessment of progress.

  1. When setting objectives: Investors are recommended to provide evidence of the approach taken to determine the objective, including any data sources. If the portfolio holds sovereigns which are categorised as EMDEs, the decarbonisation reference objective can be qualified to account for ‘fair share’ principles.
  2. When monitoring and reporting progress annually, investors are recommended to disclose:
    1. Portfolio absolute emissions (MtCOe, including and excluding LULUCF) and emissions intensity (following PCAF Standard), updating on an annual basis

The progress towards an intensity objective at the portfolio level.

The steps to set an objective for sovereign bonds are:

1. Set the scope of targets

For the portfolio decarbonisation reference objective, investors are recommended to include sovereign bonds of all maturities issued in domestic or foreign currencies.

2. Set the baseline year

Please revert to the recommendations for listed equities, corporate fixed income, real estate, infrastructure, private equity and private debt.

3. Apportion emissions

Investors are recommended to calculate the apportioned financed emissions of the portfolio. IIGCC endorses PCAF’s financed emissions metrics as a suitable standard for apportioning ‘financed emissions’ for sovereign bonds.

These calculations should cover GHG emissions from key sectors and categories such as energy, industrial processes and product use, agriculture, forestry, other land use, and waste. One of the principles of PCAF for reporting on financed emissions from sovereign debt is the reporting including and excluding LULUCF.

When it comes to the attribution of sovereign bond emissions, absolute country emissions must be normalised to allow for comparison. The Standard uses GDP adjusted for Purchase Power Parity (PPP) in international USD as a normalisation factor; this is to ensure a fairer comparison considering the size of the economies and the exchange rate effect.

Consumption-based data is recognised as best practice, however current data is limited. Investors may therefore apply the holistic or consumption emissions view on a best effort basis.

4. Select science-based net zero pathways

Investors are recommended to use regional and country decarbonisation pathways to set the portfolio decarbonisation reference objective, in an effort to account for the regional composition of the portfolio and the fact different regions are expected to decarbonise at different rates.

 

Fair share

The concept of ‘fair share’ recognises that different countries have different levels of responsibility and capability in the transition to net zero, and should therefore not be treated identically.

 

Regional and country net zero pathways

Regional pathways account for the different rates at which geographical regions need to decarbonise to contribute to global net zero emissions by 2050, as per below.

5. Calculate the portfolio decarbonisation reference objective

The objective

Investors are encouraged to set:

  • A CO2e absolute and intensity emissions reduction objective.

A five year stocktake is recommended to facilitate assessment of progress.

Investors can consider the approaches outlined in the guidance for listed equities, corporate fixed income, real estate, infrastructure, private equity and private debt:

  • A self-decarbonisation approach
  • A benchmark-relative approach

Investors are to further decide on how the objective will be quantified:

  • By applying a point-in-time GHG emissions reduction goal
  • By calculating a portfolio carbon budget

6. Monitor progress, ensuring transparency and robustness

Transparency

To ensure complete transparency, investors are recommended to:

  • Report portfolio absolute emissions and emissions intensity
  • Disclose approach taken to the calculation of the objective and decarbonisation trajectory, including any ‘fair share’ principles integrated into the approach and the data sources
  • Consider consumption-based data, which is recognised as best practice
  • Disclose the rationale for the objective
  • Where possible, seek to report portfolio decarbonisation attribution analysis
  • Disclose any rebaselining policy or process that has been developed or undertaken
Robustness

To further progress the sophistication of net zero pathways available, investors are recommended to seek to understand the assumptions behind the pathway models and avoid implementing strategies that lead to rebalancing away from emerging markets that are making efforts towards a fair low carbon transition.

For the portfolio decarbonisation reference objective, investors are recommended to include sovereign bonds of all maturities issued in domestic or foreign currencies.
