Regional differences play a role as well. Emergingmarkets managers, for example, generally
must choose among higher carbon risk companies
compared with developed-markets managers.
In the automobile industry, emerging-markets firms
have an average carbon risk score of 41.2, in
the high risk range. Developed-markets auto firms
have a much lower average carbon risk score
of 26.3, in the medium risk range. Funds in
all emerging-markets regions, except for Africa/
Middle East, have average carbon risk scores
of 15 or more.

investors wanting to lower the carbon risk in their
portfolios. Asset managers, for example, can
compare their risk scores with those of peer funds
to understand how lower-carbon-risk portfolios
differ from higher-carbon-risk portfolios across
other standard portfolio metrics. This information
can help asset managers assess the feasibility
of lowering carbon risk in their own portfolios. Fund
investors can set a goal for carbon-risk reduction
and use it to find lower-carbon alternatives.
We analyzed two Morningstar Categories, world
large-cap and diversified emerging markets, using
the Morningstar Risk Model to assess the
differences between average carbon risk funds
and lower carbon risk funds. For each of the two
categories, an iShares ETF was selected to
represent a market-cap-weighted average portfolio.
Next, the five funds in each category with the
carbon risk scores closest to 10% below the
iShares ETFs were selected and another five funds
with the carbon risk scores closest to 30% below
the iShares ETFs were selected. The 10% group and
the 30% group were then compared with the
iShares portfolios using the Morningstar Risk Model.
For world large cap, the average factor profile
of the funds with 10% less carbon risk was similar
to that of the iShares portfolio ( EXHIBIT 4 ).
This suggests that investors can lower their carbon
risk by 10% without otherwise altering their factor
exposures significantly. The 10%-lower-carbonrisk funds are somewhat more growth-oriented
(value-growth), but otherwise their factor
premiums are close to those of the market-capweighted portfolio. Investors wanting to lower
carbon risk more significantly in their global equity
exposure would experience a more noticeable
shift in style and quality. The 30%-lower-carbonrisk funds are more growth-oriented (value-growth,
valuation) and higher quality (economic moat).
For diversified emerging markets, the results were
similar. The 10%-lower-carbon emerging-markets
funds do not differ markedly from the iShares portfolio. Modest differences in the average premiums
of ownership risk, price volatility, and size
suggest the 10% group is somewhat less risky in
traditional investment terms and invests in smaller
companies. Emerging-markets investors
could lower carbon risk without otherwise making
