1. Introduction
Today I would like to focus on the so-called transition plans. In short, a transition plan
is a detailed description of actions that a company commits to implementing over a
multi-year horizon in order to comply with a given set of environmental objectives. For
instance, adhering to the Paris Agreement implies a commitment to drive net emission
of greenhouse gases down to zero by 2050.
A number of the world's largest companies have voluntarily adopted transition
plans enshrining a commitment to reduce their carbon footprint. In the financial
sector, probably the best-known initiative is the Glasgow Financial Alliance for Net
Zero (GFANZ), which involves sub-alliances for banks, asset managers and insurance
companies; for these firms the objective is to reduce the emissions financed by their
portfolios of assets.
Following a similar approach, last July the European central bank announced a gradual
decarbonization of its corporate bond portfolios, as part of a broader set of measures
aimed at mitigating climate-related financial risks on the Eurosystem balance sheet
and incentivizing issuers to improve disclosure and reduce future carbon emissions.2
In parallel, the Single supervisory mechanism is encouraging banks to adopt transition
plans consistent with the Paris Agreement and to pressure the companies they finance
to meet their transition objectives, up to the last resort of curtailing credit.3i
The topic of transition plans is relatively new. In the EU, the current legal, regulatory and
statistical frameworks rely mostly on historical emissions; the legislation that should
introduce the obligation to draw up such plans both for financial and non-financial
companies - the Corporate sector due diligence directive (CSDDD) and, for banks, the
CRR3/CRD6 package - is still on the drawing board, but is making progress.
The transition plans of financial intermediaries (banks and institutional investors)
can represent a powerful tool both for managing climate risks and for steering the
economy on a sustainable path. However, we are moving our first steps in this area. In
what follows I will discuss two issues and draw some conclusions.
2. Current vs expected emissions
An intermediary can implement a net zero transition plan in many ways. To simplify,
consider two opposite alternatives. The first would entail changing the composition
of its portfolio by moving from high to low carbon intensity sectors/firms, identified
based on their current emissions. This is the so-called "exclusion" strategy, according
to the usual taxonomy of sustainable investment.4 The second (the so-called
"best-inclass" strategy) would entail overweighting firms that, despite being carbon intensive,
have committed to an ambitious and credible decarbonization plan over the coming
decades.
The first approach, if applied on a vast scale, would suffer from a fallacy of composition:
it would be feasible for the individual intermediary, but not at the aggregate level,
short of a "miracle" in the form of a technological breakthrough allowing carbon
intensive firms to transition without financial support, or a quick and radical change
in households consumption patterns that causes a fall in demand for high carbon
products and services. The second approach avoids this problem and appears capable
of providing carbon intensive firms the finance they need to implement their transition
plans.
Figure 1 reports data for EU listed non-financial companies, aggregated by sector. For
each sector, the horizontal axis measures the current carbon intensity; the vertical axis
reports the expected decline in carbon intensity over the next decade, as envisioned
in each firms' published commitments. The figure shows that firms in the more
carbon intensive sectors plan to reduce their emissions relatively more aggressively.
This suggests that these firms, arguably the most exposed to transition risk, will need
substantial flows of finance in the coming years for their transition plans to succeed.
The figure also highlights that financial firms could face a difficult choice: in the
short-to-medium term financing the transition might even entail an increase in the
carbon footprint of their portfolios. While this might seem at odds with a net zero
pledge, it could be worth doing. Consider e.g. firms operating in the business of power
generation, often characterized by very high emissions. Their investment choices will
be key to electrify transports and heating, and will likely determine the fate of the
transition. Intermediaries should discriminate between the various companies on the
basis of their transition plans, thus allowing committed companies find the necessary
financial resources easily and at low cost, relative to less climate-aware firms. To this end,
intermediaries will increasingly need new skills, capable of screening and monitoring
long-term investment projects aimed at improving sustainability.
Figure 2 shows that there is a positive relationship between sectoral greenhouse gas
emissions and the share of firms in each sector that made sustainable investments.
In the three highest emission sectors, that account for 55 per cent of total emissions,
on average 16 percent of firms made investments aimed at increasing their own
sustainability, against a sample average of 10 percent. This suggests that the
abovementioned exclusion strategy may be a poor choice for financial intermediaries not
only as a means to support the transition, but also to mitigate transition risk in their
own portfolios.
There is increasing awareness that portfolio decarbonization - especially if carried out
in a non-forward-looking manner - may actually be ineffective to decarbonize the
economy as well as to manage transition risk. Recent initiatives aimed at developing
forward-looking tools and metrics, the so-called portfolio alignment tools, build on
non-financial firms transition plans.5 Progress on this crucial front is ongoing.6
Overall, a trade-off between simplicity and effectiveness emerges. Decision-making
processes relying on forward-looking information, such as transition plans, offer the
most effective incentives and do not suffer from the pitfalls often marring those based
on historical information. At the same time, they introduce complexity and uncertainty:
at present the legal framework, the statistical apparatus and the reporting requirements
for firms largely rely on historical, backward-looking data; only a relatively small group
of large non-financial firms worldwide has elaborated transition plans;7 furthermore,
reliance on transition plans is warranted only if they are ambitious and credible (and
possibly validated).
3. Possible trade-offs between sustainability and returns
A second important theme concerns the relationship between the environmental
objectives of firms and their traditional business objectives. This issue can be framed
within the academic debate about whether firms should stick to a narrow mandate
- maximize profits to the benefits of shareholders - or rather be concerned with a broader
set of targets - loosely speaking, maximize the welfare of stakeholders. In the latter
case, firms should internalize their negative externalities, including those related to their
greenhouse gas emissions.8
This yet unsettled debate has important implications for net zero transition plans. The
empirical evidence suggests that so far sustainable investment strategies have reaped
some (modest) extra returns relative to the traditional approach, while sustainable
bonds have been producing (modestly) lower yield.9 This apparent contradiction can
be explained by a surge in demand for financial assets labeled as "sustainable" due to
investors' increasing sensitivity to environmental issues. However, this is a temporary
phenomenon. But in the new equilibrium sustainable assets should carry lower transition
risk, and hence a lower return, which investors might be reluctant to accept. Also, we
cannot rule out that sustainability objectives might eventually conflict with a risk-adjusted
return target. After all, internalizing externalities is costly, and brown firms might keep a
competitive advantage in terms of pure profits.
In summary, it cannot be excluded that at some stage the transition plan and the
decarbonization objectives adopted by an intermediary might conflict with the traditional
investment objectives. If this turned out to be the case, what should be done?
A recent report published by the Glasgow Financial Alliance for Net Zero (GFANZ)
provides a tentative answer: the choice should be explicitly addressed in a financial firm's
transition plan. In particular, the plan should include a statement detailing, inter alia,
how the institution "plans to address potential conflicts between its net-zero ambitions
and profit-making opportunities."10 This amounts to saying that the preference for
sustainability should be an argument of the intermediary's utility function, at par with
the return and risk preferences. In other words, the intermediary should explicitly state if,
and to what extent, it is willing to sacrifice return for sustainability, should a sacrifice turn
out to be necessary.

In the seventies M. Friedman argued that the purpose of a corporation and its managers is exclusively
the maximization of the value of the firm, to the benefit of shareholders. This theory advocates a
clear distinction between this narrow mandate of the firm and the broader objectives of society; the
latter, grounded on ethical and social principles, should be pursued by the government. A debate
on this theory has emerged in recent years, as the growing concern on ESG issues by the public
have prompted many leading firms to embrace a broader set of targets than profitability and adopt
sustainable policies. For instance, according to C. Mayer (2018), "Prosperity: Better Business Makes the
Greater Good", Oxford University Press, managers should balance a mix of objectives and address the
related conflicts of interest by allocating the value created by the firms among shareholders and the
other stakeholders, to the benefit of society in the long term. Hart and Zingales (2017), "Companies
Should Maximize Shareholder Welfare Not Market Value", Journal of Law, Finance, and Accounting no.
2 support the thesis which gives the title to their work, if this is consistent with the firm's shareholder
preferences. Broccardo, Hart, Zingales (2020), "Exit vs Voice", European Corporate Governance Institute
- Finance Working Paper no. 694, argue that if the majority of shareholders is socially responsible,
"voice" achieves the socially desirable outcome in companies that generate externalities; whereas in
the case they are the minority "exit" (divestment and boycott) is a more effective strategy. However,
the latter policy is not socially optimal.

GFANZ (2022), "Financial Institution Net-zero Transition Plans", version for public consultation, June, p.
23. This recommendation does not appear in the final version of the report, released last November.
This line of reasoning has potentially wide implications for financial intermediaries'
behavior and for the design of their transition plans.
First, it seems doubtful that net zero pledges can be credibly announced without
mentioning the potential trade-off with returns. To my knowledge, to date few if any
intermediaries have been explicit about this potential trade-off. One possible reason
is that many of them have a fiduciary duty towards their clients, and have not yet
asked, let alone received, a mandate to sacrifice returns for sustainability, should this
become necessary. An investor trusting her savings to a fund manager, or an insurance
company, has probably been attracted by the win-win narrative emerging from the
data thus far (sustainable investing is good for the planet as well as for the investor's
wallet), but might well change her investment choices if conditions changed. In that
case, the intermediary would have to follow its client's guidelines. Furthermore, whereas
many investors express a demand for sustainable assets, others do not; intermediaries
featuring both investor types among their clients can hardly make pledges on behalf of
the latter.
In sum, net zero pledges by financial intermediaries should be more appropriately viewed
as conditional commitments, as they could be incompatible with a sacrifice in terms of
return which might at some stage materialize and which the intermediary's shareholders,
or its clients, might be unwilling to accept. Unless this issue is addressed, the net zero
pledge framework set up by the financial industry in recent years might be at risk of
unraveling, if and when difficulties materialize. Some recent developments give food for
thought.11
Second, there are reasons to doubt that investors would be willing to prioritize sustainability
at the expense of profitability. Even if some were, recent theoretical analyses suggest
that their efforts could be undermined by opportunistic investors focused solely on the
risk-return paradigm, who would invest in companies not interested in sustainability
standards. There is therefore a risk of "carbon leakage": responsible investors would give
up their returns to the benefit of other investors, with limited effects in terms of progress
on the climate front;12 this might be yet another instance of the "waterbed effect" which
mars economic policies in many areas.
4. Conclusions
A strategy to promote an orderly transition of the economic system towards the Paris
goals should be multi-pronged.
First, to reduce the risk of elusion and waterbed effects it is necessary to leverage the
entire financial system: banks, asset managers, insurance sectors. But excessive reliance
on the financial sector to induce the transition should be avoided. Decarbonising financial
portfolios and decarbonising economies are two sides of the same coin. Simply cutting
exposures to high emission firms will not help progress towards a sustainable economic
development, and is unlikely to reduce transition risk in the intermediaries' portfolios.
Furthermore, intermediaries should be explicit and transparent with their customers and
shareholders about the possible trade-offs between returns and sustainability objectives,
and take a stand on this issue. In particular, it seems doubtful that net zero pledges can
be credibly announced without mentioning what line of action would be taken should
environmental and return objectives happen to clash. Net zero pledges by financial
intermediaries should more appropriately be viewed as conditional commitments, as
they might be incompatible with a sacrifice in terms of return which might exceed some
yet unspecified threshold. To my knowledge, to date few if any intermediaries have been
explicit about this potential trade-off. If not addressed, this ambiguity might represent a
serious obstacle to the financial system's contribution to the fight against climate change
and to an effective approach to transition risk management.
Second, a multi-pronged strategy should put non-financial companies at the center,
beginning with the large ones and those with high emissions, prompting them to adopt
ambitious and credible transition plans. This choice rests with shareholders; public
policies should encourage them via incentives and/or penalties; financial intermediaries
can also play a role on this front.
The European legislation does adopt such a multi-pronged approach. By introducing
mandatory transition plans for all large companies, financial and non-financial, the CSDDD
aims to bring about a virtuous convergence of the entire economic system towards the
principles of the Taxonomy and the Paris goals. The draft CSDDD also features specific
mandatory provisions to link the corporate manager remunerations to sustainability
indicators. This seems a step in the right direction.
In the EU context the risk of waterbed effects is assuaged, but might not disappear.
Investors interested only in expected returns could look outside Europe. In such an
uncertain situation financial intermediaries and non-financial companies should liaise
to align climate change mitigation policies and climate risk management, with a greater
consulting role by intermediaries and greater transparency by companies. A promising
area for cooperation is sustainability data, where massive gaps are recorded. Overall, a
greater role for public policies, especially in non-EU jurisdictions, seems necessary for a
successful transition.
