Vitor Gaspar , Director of Fiscal Affairs of the International Monetary Fund IMF , stressed the importance of having a well functioning financial system in the euro area and illustrated the complex interplay between reforms and fiscal policy. Marco Butti , Director-General for Economic and Financial Affairs at the European Commission, warned against too many governments relying too much on the expansionary monetary policy.
Regarding the international challenges for monetary policy, Thomas Laubach of the Federal Reserve as well as the Deputy Governor of the Bank of Japan, Hiroshi Nakaso, agreed on the point that most central banks were primarily oriented towards domestic objectives. International collaboration still seemed to be an exception. Laubach, an advisor to Fed chair Janet Yellen and a former Professor at Goethe University, stressed the need to foster clear communication between central banks.
As a lesson from recent experiences, Philip Lane , Governor of the Bank of Ireland, emphasized the advantages of international coordination by sharing conjunctural assessment, thus gaining clarity about policy feedback rules. Williams appealed to include instruments of unconventional monetary policy as part of the regular toolkit in times of low inflation. He asked academics and researchers to rethink whether inflation targeting was the best way for central banks to achieve their objectives.
Wieland pointed out that a setup with rules "could strengthen a central bank's decisions". Compile a new entry. According to the Governing Council of the ECB, the monetary policy stance will remain accommodative for as long as necessary, and it expects the key ECB interest rates to remain at present or lower levels for an extended period of time. The two main weapons were large-scale purchases of long-term securities quantitative easing and the commitment to keep short-term rates low for a specific period forward guidance.

Um die Wirtschaft anzukurbeln, griffen die Zentralbanken daher zu unkonventionellen Instrumenten. The following revision to the model for externalised costs is directly relevant to the assessment and management of the physical systemic risk. The divergence between the lower SCC and higher Paris- consistent prices reflects the difference between neoclassical efficiency and climate safety as normative criteria for policy making.
Aglietta and Espagne argue that improving market efficiency should not be relied upon as a governance framework, and that the SCC should be abandoned in favour of collective insurance for climate safety. In the following sections we discuss a solution to the dual problems of a market efficiency, and b systemic risk, by expanding the standard model for the externalised costs of carbon emissions.

The standard model for the externalised cost of carbon emissions is based on the SCC, as indicated in Equation 1. The standard policy response is to tax carbon emissions to internalise the SCC, as indicated in Figure 2. The standard approach is to select market-based climate policies based on cost-benefit analysis CBA. CBA is efficiency orientated and supports the objective of achieving efficient markets. This is because the SCC is not a risk-based cost metric. Weitzman, ; Dietz, Gollier and Kessler, , but such approaches have not been met with broad acceptance. Adjusting the time discounting can even lead to paradoxical results in terms of future consumption and investment e.
Nordhaus, b. In the following section we present an amendment to the standard model for addressing the physical systemic risks created by carbon emissions. Equation 1 Figure 2. Hypothetical mitigation by a market actor based on the standard model for externalities and incentives.
The pink shaded area represents the total carbon tax collected over time. The second type of insurance is preventative insurance. An example is preventive health services under the U. Patient Protection and Affordable Care Act : insurance coverage that aims to prevent the onset of disease. What is the cost of a collective and preventative insurance policy that can protect the world against 1. If we denote this cost as the Risk Cost of Carbon RCC , then we may begin to appreciate that an expanded model for externalities is plausible based on the concept of preventative insurance.
The SCC could be revised higher by proposing different time discounting parameters and damage functions, but these solutions are ad hoc and do not explain why the SCC can fall short of the scientific consensus on climate-related systemic risk. Here we clarify the model of Chen, van der Beek and Cloud ; by emphasising that the inability to address risk is an inherent shortcoming of the standard model refer Equation 1 because the SCC denotes a negative externality, whereas the RCC denotes a positive externality, as defined in Equation 2 and illustrated in Figure 3.
Equation 2 Figure 3. Hypothetical mitigation by a market actor based on the expanded model for externalities and incentives. The pink shaded area represents the total carbon tax collected over time, and the green shaded area represents the total carbon reward issued over time.
The RCC is a measure of the cost of implementing collective-preventative insurance against climate change. This paradox is illusory, because the positive externality is the preventative insurance, which is a public good. This public good is not functionally important in the economic process because it is the reward price that actually incentivises markets and not the benefits of the reward price.
The RCC is used to determine the average reward price for carbon. These policy choices are unusual, however, because no other pollutant has been managed with this expanded model for externalities. The inspiration for developing the HMH is the strong coupling that exists between carbon and energy. This coupling is not a feature of other pollutants, and so the expanded model is considered a special case that might only apply to carbon emissions.
The HMH is original because it takes into consideration the entropy2 of carbon when comparing climate policies.
Der Mut zur Normalisierung der Geldpolitik
The HMH is not discussed here in detail for reasons of brevity, however it is worthwhile noting that the expanded model is consistent with the Tinbergen Rule : a principle that there must be as many policy tools as policy objectives. The policy involves Carbon Quantitative Easing CQE , which is mentioned in the title of this paper and is described below. The Global Carbon Reward is a policy that functions as preventative insurance for avoiding unwanted climate change, and it is designed to internalise the Risk Cost of Carbon RCC into the economy using unconventional monetary policy and open market operations.
Two points of clarification are necessary before considering this policy. Firstly, the Global Carbon Reward does not replace carbon taxes or cap-and-trade schemes etc. Secondly, although the Global Carbon Reward is an unorthodox policy, it is believed to be fundamentally important because it enables carrot-and-stick pricing when applied with carbon taxes or cap-and-trade. The operational 2 The entropy of a system is an expression of the disorder of the system, and it is an emergent property with a statistical explanation.
The entropy of the Universe increases until it reaches maximum entropy at thermal equilibrium. The CBDC is offered to market actors as a financial incentive for the abatement and sequestration of carbon. The financial reward for market actors is the seigniorage income after the CBDC is digitally created. The seigniorage income is the face value of the CBDC less fees and commissions.
Administration of the policy is funded with fees and commissions that are subtracted from rewards to cover the cost of measurement, reporting and verification MRV of the carbon stocktake, long- term monitoring, policing, RCC assessments, and general administration. For example, the CES can make public announcements concerning future CBDC prices, and can adjust the rules and guidelines regarding the carbon mitigation technologies and market sectors that are open to receiving rewards under the policy. The CES may allow the CBDC to be traded instantaneously over a peer-to-peer exchange platform, but this option needs to be managed in terms of the economic and regulatory implications.
Chen describes a mechanism for the CES to manage the carbon stocktake should actors default on their service agreements. The CBDC circulates in the economy and is openly exchanged for hard currencies. From a monetary perspective, the CBDC may be defined as a representative currency because its supply is constrained by the carbon stocktake that is managed by the CES. From a financial perspective, the CBDC may be defined as a security because it has the attributes of a sovereign bond. From a legal perspective, the CBDC may be defined as an international unit of account, and it could be managed like a parallel currency.
For tax purposes, the CBDC may be classified as a currency, a bond, or a commodity. The internalisation process for the RCC does not occur in the same way as with the SCC, and this is because the policy for carbon rewards does not seek a social welfare maximum. The target rate of mitigation corresponds to the level of physical systemic risk that is deemed acceptable under existing and new international agreements. The internalisation of the RCC involves setting a carbon reward price in world markets—with CBDC seigniorage income being the incentive for mitigation—and then allowing market actors to trade the CBDC.
The internalisation process occurs when market actors undertake long-term mitigation actions and increase the CBDC supply. The CBDC supply is an important macroeconomic index for mitigation success. The CBDC is attractive as a security because it has a risk-free rate of return i. The internalisation process also involves annual risk assessments refer Section 4. The SRACC represents the estimated average international price of mitigating carbon at various rates, and is based on experience with existing abatement and sequestration technologies.
The carbon reward price, P4C, is expressed as an exchange rate, with 4C as the base currency and the USD as the quote currency see Equation 3. The P4C price alert is to be presented in the international media and revised annually in response to the changing risk exposure.

Hypothetical forecast of the 4C yield over the coming years. A positive yield represents a risk-free return on 4C holdings adapted from Chen, van der Beek and Cloud, Figure 6. Hypothetical forecast of the 4C supply over the coming years; and the partition of 4C holdings between private traders, central banks, and the CES. These actions may involve a wide spectrum of technologies, and may occur in all sectors of the economy, such as in energy supply, transportation, construction, heating and cooling, agriculture, land and ocean management, manufacturing, family quality, etc.
Each technology requires a rule for assessing its emissions baseline and mitigation rate, and also for defining suitable service agreements. A formula for the financial incentive for market actors is shown in Equation 4. This incentive is the seigniorage income, SI t , that is offered to market actors who undertake mitigation work. Seigniorage is traditionally afforded to central banks when they print money and earn the face value of that money less the cost of production. The mass of carbon mitigated, m t , is determined through a measurement, reporting and verification MRV process.
Market actors are required to enter into service contracts with the CES before receiving their seigniorage income. Equation 4 4. The price alerts will incentivize private purchases of 4C in foreign exchange markets based on the advertised 4C yield over time—Y4C t —which is the annual ex ante change in the 4C price, as follows: RCC! Equation 5 A key feature of the policy is that market sentiment for 4C is influenced by Y4C t forecasts that are presented by the CES to the marketplace and citizens.
The CES will implement rules and strategies to provide adequate 4C price stability. Based on the assumption that the CES will be effective in managing 4C, positive Y4C values will occur during periods of rising climate risk, and this will guide a managed secular bull market in 4C trade refer Figure 5.
On the other hand, negative Y4C values will occur during periods of falling climate risk, and this will guide a managed secular bear market in 4C trade. Bull and bear markets will continue until a quasi-steady risk condition is achieved refer Figure 5. These dynamic features of the financial mechanism are the primary channel for mobilising private wealth into climate mitigation actions, and they create a negative feedback on global warming. The rate of wealth mobilisation under the policy is always commensurate with the assessed physical systemic risk, as denoted by RCC t.
A hypothetical scenario is shown in Figure 6 for the cumulative 4C supply S4C. Figure 6 shows the hypothetical amounts of 4C held by private traders, central banks, and the CES. A small percentage of 4C is claimed by the CES to cover administrative costs. Figure 7. Simulated global mean surface temperature increase as a function of cumulative total global CO2 emissions reproduced from IPCC, An order-of-magnitude estimate of S4C can be found by assuming that the policy will be implemented between to reduce global warming from 3.
Using the data presented in Figure 7, the carbon stocktake that corresponds to mitigating from 3. This scenario corresponds to about 20 trillion units of 4C issued between —or billion units of 4C issued per year on average—as a rough guide. Before we discuss the policy implications, we will first consider whether human cognition could be playing a role in limiting our policy options. We then review the definition of a market failure, discuss environmental and social governance ESG , and offer justifications for expanding the mandates of central banks to provide scalable climate finance and to manage climate-related systemic risk.
There are things we do not know we don't know. The things we do not know, or do not have words to express, can cause hypocognition. Hypocognition occurs when a specific concept is not represented in language resulting in some dysfunctional behaviour. Hypocognition was first recognised by Robert Levy after studying Tahitians and their emotional responses to situations that had no name in their native tongue.
