Build Back Better - Mobilising Private Finance for a Green Recovery

Keynote speech by Luigi Federico Signorini,

City of London Corporation, 15 October 2020

That climate change is one of the key challenges of this century there can be little
doubt. To what extent humankind will be able to rise to this challenge depends on several
actors, each playing their role. Let me start by listing three of them:

¢ individuals;
* governments;

¢ the market and financial authorities, including central banks.

The list is not, of course, exhaustive: it is meant to provide a background for what
I shall say when developing this meeting's theme, emphasising among other things the
role of central banks and financial supervisors. At the end, I am going to add some words
on the Bank of Italy's own sustainable investment policies.

A premise is in required. Whatever the eventual route to climate action, full awareness
among the general public must be the starting point, at least in democratic countries that
use the market to allocate economic resources. People's awareness drives their choices
as consumers, voters and investors. It thus ultimately shapes the performance of the
whole cast of actors.

Awareness of climate change, and of the need for action to tackle it, has rapidly
increased in countries around the world, with Europe at the forefront. In the latest
Eurobarometer' survey, the majority of respondents in 19 countries think climate change
is one of the most serious problems facing the world today. In all but one country,
respondents are now more likely to think this way than they were in 2017. Even in the US,
where opinions on climate change are divided, 59 per cent of the population considers
climate change a major threat.

Individual behaviour matters a great deal, and many people (especially, but by
no means only, the young) make conscious pro-environment choices nowadays about

issues that were just a fringe concern a generation ago. This applies to all sorts of things,
from sorting rubbish to changing light bulbs to choosing a motor vehicle - or, for that
matter, a vehicle for financial investment. Retail investors, in fact, are also increasingly
interested in climate-friendly financial products. This is as true in my country? as in other
parts of Europe.'

However, besides reflecting personal preferences, people's behaviour also
responds to incentives, and is constrained by rules. Here is where the government
actor enters the stage.

As Governor Visco® recently observed, defining policy action to pursue climate
objectives is the primary responsibility of governments. In a democratic polity, it is
for elected officers to decide on the ultimate balance of the benefits and costs of any
environmental policy.

Seen from an economist's point of view, one key issue for governments to decide
on is finding ways to make agents internalise climate externalities. Progress on this
front, while undeniable, has only been partial. Carbon taxation (the economic theorist's
favourite tool, as it makes fewer demands on the government's information set and relies
more on market decisions), covers just a tiny fraction of global emissions.° Most existing
carbon pricing systems rely on cap-and-trade, a framework that is prone to extreme price
volatility and corner outcomes, and is therefore often regarded as second best. Still, even
in Europe, where this system is widespread, the market for allowances only covers about
AO per cent of emissions.

The current crisis has further and significantly lowered fuel prices. If price-based
market allocation is to help achieve the Paris targets, more action is needed on the fiscal
and regulatory side.

Governments can also fund low-carbon projects directly, as envisaged for instance
in the 'Next Generation EU' plan.' However, the size of the investments needed is likely
to go far beyond whatever governments will directly fund. According to Commission
estimates, the European plan to become carbon-neutral by 2050 requires €350 billion
of additional investments in 2021-2030.° In contrast, the whole EU budget expenditure
for 2020 amounts to €155 billion. While national governments spend much more,
achieving the global climate targets must realistically assume that private finance will
play a central role.

In fact, market appetite for greener finance has not been lacking recently. The size
of the sustainable asset management industry is expected to reach $45 trillion by the end
of 2020,"° almost twice the amount in 2016." Green finance instruments have grown very
rapidly in response to strong demand." Issues of green bonds exceeded $200 billion in
2019, with a possible new record in 2020; the total outstanding amount has reached $1
trillion.'"? According to one source, the net inflows in US sustainable investment funds
hit a record $20.6 billion in 2019, nearly four times as much as in the previous year."
The number of institutional investors that signed the UN Principles of Responsible
Investment has soared to 2,829, accounting for $90 trillion of assets under management;
by subscribing, those investors have committed to seeking appropriate disclosure on
ESG issues from the entities in which they invest.'>

As an aside, it is welcome news for my country that one top data provider has
recently placed Italian sovereign bonds among the least risky in the euro area after
adjusting for transition and physical risks, and for economic resilience.'* This is linked to
the fact that, as of 2020, the country has achieved all the European energy and climate
targets."'

To ensure that the drive towards sustainability in finance is itself sustainable, much
remains to be done.

For agents to make informed choices about climate issues, good data and sound
analytical tools are essential. The situation is hardly satisfactory. 'Currently, there are
neither widely accepted rules for ESG data disclosure by individual firms nor agreed
auditing standards to verify the reported data... ESG-score providers rely heavily on
voluntary disclosure by firms and on subjective methodologies to select, assess and
weight individual ESG indicators. This adds to the arbitrary nature of the scores. As a
result, ESG scores of individual firms differ greatly across rating agencies if compared, for
example, with credit ratings'.'®

ECB Board member Isabel Schnabel recently argued that 'mispricing' in climate-
related market outcomes exists 'as a result of informational market failures that stem
primarily from the absence of a clear, consistent and transparent globally agreed
taxonomy accompanied by disclosure requirements'.'?

Considering the vast amount of investment at stake, there is also the risk of
'greenwashing'. (Not to mention the bubbles based on fads or misleading labels, which
may emerge in green finance as easily as in many other markets; but better information
can only do so much about this).

Several initiatives may improve the situation. A dedicated task force created in 2015
by the Financial Stability Board has been promoting voluntary climate-related disclosure
by companies; it has seen progress, though its own assessment is that results remain
disappointing. More recently, the Network for Greening the Financial System, a voluntary
gathering of central banks and financial supervisors, has been active in promoting ways
to bridge data gaps. As is well known, in Europe the main initiative to improve climate-
related information is the EU taxonomy, which sets out detailed criteria for identifying
economic activities that contribute to the EU's climate (and other sustainable) objectives."°

How data are used to assess risk is also a matter for concern. The characteristics
of conventional models (e.g. widespread assumptions about the distribution of shocks
or the linearity of impacts) may fail to take account of certain unique features of climate
risks.2! Prudential authorities are increasingly asking financial intermediaries to improve
their models and integrate climate risks into them."* In May, the NGFS published its guide
for integrating climate-related and environmental risks into prudential supervision."? The
ECB recently consulted on a 'Guide on climate-related and environmental risks',4 which
explains how supervisors expect banks to consider climate-related and environmental
risks in their governance, risk management frameworks, and business strategy.

It is good to preserve a distinction between general climate policies, which are the
responsibility of governments, and actions to ensure the proper management of climate
risks, which are an integral part of financial authorities' remit. A discussion is ongoing on
a differential prudential treatment of bank exposures, based on the climate implications

20 Financial products distributed in the EU will have to demonstrate that the underlying investments
are taxonomy-compliant in order to be labelled as 'sustainable'. To foster the adoption of the EU
taxonomy, companies subject to the EU Non-Financial Reporting Directive will be required to disclose
whether, and to what extent, their activities are taxonomy-aligned.

of the activities they finance. My view is that a 'green supporting factor' is justified to
the extent that there is evidence that green (brown) loans carry a lower (higher) risk for
the lender;*> not as a general policy incentive, which is best pursued through other tools,
such as taxes or subsidies.

Economists and central bankers are also debating the extent to which climate
considerations should enter monetary policy strategies. It is not possible to discuss
this point here at any significant length. Let me just observe, very briefly, that climate
events can powerfully affect key macroeconomic variables such as output, consumption,
investment, productivity and inflation.2* Macroeconomic climate risks are no easier to treat
than the corresponding micro risks, because of the marked uncertainty that surrounds
them, of the possibility of rare, high-impact events that are notoriously difficult to model,
and of all the nonlinearities involved. The central banks' macro modelling toolkit will
need to be enriched in this respect.

Besides monetary policy portfolios, central banks also own a significant amount
of non-policy financial assets. Should climate considerations have a place in their
management? There are two reasons for answering this question in the affirmative. One
is reputation and good citizenship: central banks' investment must be seen as beyond
societal reproach. The second is that central banks, as long-term investors, need to take
the long-term sustainability of their investments seriously into account.

In doing so, central banks should strive, in my view, to keep their investment policies
as politically neutral and market-neutral as possible. Political neutrality is ingrained in their
institutional position, and a necessary companion to their independence. While bound in
Europe to 'support the general economic policies in the Union', central banks should not
be seen as taking upon themselves the role of democratically accountable institutions,
or as passing judgment on one particular government's policy. Market neutrality cannot
be strict: climate-oriented investment does, after all, imply by definition a departure
from market neutrality; but this should be kept to a minimum, avoiding unnecessary
discretionary or discriminatory choices. (Similarly, central banks' monetary policy, while
precisely designed to affect certain market variables, usually strives to stay away from
unduly influencing market allocation beyond what is inherent in the policy itself).

Therefore, it is my view that central banks' climate-related investment policies should
be based, to the extent possible, on predetermined, objective and transparent criteria.

Since 2019, the Bank of Italy has been using ESG criteria for the investment of its
non-monetary equity portfolio, while broadly preserving neutrality and diversification.
We do not invest in companies that operate mainly in sectors not compliant with the

product-based exclusions of the United Nations Global Compact.?' We overweight those
with the best ESG profiles, based on an external provider's ratings."° In 2019, after the ESG
strategy had been introduced, the carbon footprint of our equity portfolio dropped by 30
per cent compared with the previous year. We are committed to further improving the
environmental footprint of our investments, by applying sustainability criteria to a larger
section of our portfolio. The Bank of Italy discloses on a regular basis both its operational
principles for ESG investment, and the results in terms of its carbon footprint.

We acknowledge that the current ESG ratings are an imperfect measure of
climate risk, and support the development of more consistent, comparable and
forward-looking data and scores.*? We also support research on sound climate-risk
assessment methodologies (such as scenario analysis, and stress testing for transition
and physical risks), participating in Eurosystem-wide developments. President Lagarde
confirmed yesterday that the Eurosystem, as part of its ongoing strategic review, is
considering whether to consider climate change profiles in its operations.*°

We favour any progress towards enhanced international cooperation in climate
matters among regulators, supervisors and standard-setters. The Bank of Italy is an active
member of the Network for Greening the Financial System. As this audience knows, the
UK and Italy share the responsibility of promoting international climate cooperation
through the upcoming COP26.

The awareness is growing worldwide that, if the goal of keeping the warming of the
planet within safe boundaries is to be achieved, urgent action is needed to accelerate the
transition towards net-zero global emissions. Every actor must play their part. Markets
have proved themselves ready to embrace green finance, given the right incentives.
Change cannot just be legislated into existence, but public policy has a key role, including
providing a stable climate-friendly regulatory framework. Financial authorities should
promote the adoption of sound climate-risk assessment practices, and support the
production of adequate data; while staying within their mandates, they can significantly
contribute to achieving the common goal.

ar This is the agreement, approved in 2004, which establishes the principles that companies should follow
in the areas of human rights, labour, environmental sustainability and measures to prevent corruption.
Companies in all sectors can adhere to this agreement, except those involved in the production of
tobacco and controversial weapons.
