Basics of Social Cost of Carbon

Governments have many policy options to curb carbon dioxide (CO2) emissions and slow down global warming. There are a wide range of estimates of costs that these policies will impose on governments and taxpayers. If the government doesn’t do anything or do much, society will inevitably pay the price. According to a study by the Institute of Policy Integrity, climate change could cost the world some $1.7 trillion a year by 2025, increasing to about $30 trillion a year by 2075.

The social cost of carbon (SCC) is the monetary value (say, dollars) of the economic damages that would result from emitting one additional ton of greenhouse gases into the atmosphere.

The social cost of carbon is a tool that helps policymakers determine whether the costs and benefits of a proposed policy to curb climate change are justified. A higher SCC generally means that the benefits of a particular climate policy to cut CO2 justify its cost; a low SCC makes a policy seemingly cost more than the benefits it ultimately delivers.

Estimating the dollar amount of SCC requires information that links social, economic and physical features into one framework. This information is then fed into computer models. These models integrate four types of information:

  1. Predict future emissions: These are based on population, economic growth, and other factors.
  2. Model future climate responses: Future emissions are estimated and based on these estimates, the impact is assessed regarding increased temperature and sea-level rise.
  3. Assess the benefits and costs: What will be the impact of climate change on agriculture? What will be the cost of adaptation to sea level rises? What will be the impact of additional warming on energy use? What will be the impact on worker’s productivity?
  4. Convert to present value: Since benefits and costs are likely to accrue over time, policy decisions need to be taken today. Hence you discount the future costs and benefits to today. At what discount rate? It is the discount rate that indicates a willingness to spend today to protect future generations.

Simulation of the three models is run hundreds of thousands of times using different values for uncertain variables and parameters. As a result, many estimates of SCC emerge. SCC is usually represented as a range rather than a single number. An average of all the estimates is taken at a particular discount rate to deliver a representative SCC. A representative computation is shown below:

We can get a sense of SCC by seeing that it was estimated that India’s country-level social cost of carbon emission the highest at $86 per tonne of CO2 in the world. This means that the Indian economy will lose $86 by emitting each additional tonne of CO2. Next in scale is the US, where the economic damages would be $48 per tonne of CO2 emission and Saudi Arabia at $47 per tonne of CO2 emission.

SROI: Tackling the Measurement Challenge

The concept of Social Return on Investment (SROI) emerged from the work done by the Roberts Enterprise Development Foundation (REDF). Originally intended for large social enterprises, over time it has been fine-tuned to meet the requirements of various types of organisations. SROI is an outcomes-based measurement tool that helps organisations to understand and quantify the social, environmental and economic value they are creating. In effect, SROI captures the triple bottom-line of people, profits and planet.

Every business needs to periodically measure its performance. One of the ways of measuring the company’s performance is the accounting rate of return.  This is simply the profits that the company has earned divided by the investment that it made in the business. Companies are also impacted by externalities – things that take place outside its factories. These externalities are not captured in the accounting rate of return.

Externalities are best understood by examples. For example, if the factory’s chimney releases smoke it has harmful consequences on the people and farms nearby. This is beneficial and is called negative externality. On the other hand, if the company builds a road to its factory then it makes it easier for people in nearby areas to commute. This is positive externality.  Every social and sustainability action of a company will have an impact in terms of externalities. To measure the performance of a company’s social and sustainable actions we use the metric – social return on investment or SROI as it is popularly called.

In practice, there are two ways of calculating SROI depending on the level of measurement. When the measurement is undertaken at the company’s level, it is based on both social and economic benefits and considers economic as well as social investments. On the other hand, when the measurement is undertaken at the project level it is simpler to look at only social costs and benefits and relate them to social investments.

Thus, the company level measurement is defined as: SROI=(Economic profit + Social profit)/(Economic investment + Social investment). Here social profit is social benefits less social costs

And, the project level measurement is defined as: SROI = Social profit/Social Investment.

THE PRINCIPLES OF SROI

There are seven principles of SROI that support the application of SROI. These are:

Involve stakeholders: Stakeholders are the ones who are most impacted by the change being brought about. They should be informed and identified and involved during the entire process.

Understand what changes: There are two types of outcomes of any change process—intended outcomes and unintended outcomes. It is necessary to have sufficient proof of the changes that have been brought about.

Value the things that matter: Value all things that matter. Where direct measures are unavailable, suitable proxies should be used.

Only include what is material: Materiality requires an assessment of the criticality of that piece of information to the decision at hand. If this is information is excluded would the decision-maker make a different decision?

Do not over-claim: Only that portion of benefits should be claimed that the organisation is responsible for creating.

Be transparent: All inputs and outcomes must be documented and made available to the stakeholders.

Verify the result: The results of SROI should be vetted by an independent assurance agency for it to be credible.

THE SROI MEASUREMENT PROCESS

Unless one follows a systematic process to arrive at SROI, the outcome is unlikely to be credible and reliable. The following steps are recommended for arriving at a credible and reliable SROI.

Step 1 – Map the stakeholders: It is important to establish the boundaries of the SROI measurement. First, one needs to figure out the outcomes of social intervention. Second to figure out who the stakeholders of the social project are. It may be worthwhile to list the stakeholders. Finally, one needs to understand how to involve the stakeholders in the project.

Step 2: Mapping the outcomes:This is undertaken by means of impact maps. To understand an impact map, let us take the example of a company constructing a farm pond. The farm pond provides benefits to agriculture, humans, and animals. For agriculture, benefits may be in terms of increased yields and/or more crops in a year. For humans, more water is available for drinking. bathing and cooking. Milch animals may yield more milk. Although there may be lots of benefits, most of them will add little value to the impact. These need not be considered. As the accountants will tell you these fail the materiality test. Once the benefits are identified these need to be converted to monetary terms.

One of the interesting things about outcomes is that they often depend on circumstances. For example, a water project in an arid area is more valuable than one where water is relatively easily available.

Step 3 – Evidencing the outcomes and giving them a value: Step 2 provided a qualitative measure of the outcome of the social project. However, it is also important to put a monetary value to the outcome. This involves (i) developing outcome indicators; (ii) collecting outcomes data; (iii) establishing how long outcomes last; and (iv) putting a value on the outcome.

Step 4: – Establishing the impact: The outcomes that we measure should be auditable. Hence it is essential that outcomes are not over claimed. Also, we need to figure out how much of the impact is because of one’s own activity and how much of it would have taken place anyway or how much of the outcome would have occurred without our intervention and how long will the benefits last. This requires measurement of three key metrics:

Deadweight is a measure of the amount of outcome that would have happened even if the activity had not taken place. It is calculated as a percentage.

Attribution is an assessment of how much of the outcome was caused by the contribution of other organisation’s or people.

Drop-off is used to account for how the outcomes, in future, are likely to be less than current measurements. It is only calculated for outcomes that last more than one year

Step 5 – Calculating the return: Now all the inputs and outputs have been measured, SROI can be calculated using formula listed in the section Social Return on Investment.

Step 6 – Conducting a sensitivity analysis: Relying on a single SROI number can be dangerous. Many assumptions are made while computing SROI. Hence it makes sense to test the robustness of SROI to these assumptions.

ADVANTAGES AND DISADVANTAGES OF SROI

Like any measurement SROI also has its advantages and disadvantages. All the advantages and disadvantages of economic ROI apply to SROI as well and some more.

Advantages

  1. It is simple and easy to calculate. Requires only two pieces of information—profits and investment—numbers that are already available in financial statements.
  2. It measures profitability by scaling social profits to the investment made. Thus, companies are comparable on SROI.

Disadvantages

  1. SROI measurement is impacted by the point of time when the measurement is undertaken. Thus, in a multi-year project, SROI could be different in each of the years. This causes confusion.
  2. Profit (the numerator) is impacted by accounting choices. Different depreciation policies could lead to different profit numbers even though there is no change in the underlying business.
  3. Measuring social costs and benefits often requires measuring shadow prices—making it complicated to apply in practice. For example, where water is conserved in a water-scarce area, the value of water conservation depends upon the extent of water scarcity. Higher the water scarcity, higher would be the value of water.
  4. Measurement of deadweight, attribution and drop off poses significant challenges as there are no direct measures. Estimates must be made based on prevailing local conditions. Such measurement errors could have a significant impact on SROI.

Blockchains and responsible business

Contracts, transaction and their record form the foundation of our economic, legal and political systems. They help protect assets and set boundaries of an organisation. They are critical to establishing the and verifying identities and chronicling events. They govern interactions among organisations, communities, and individuals. And, they guide managerial and social action. The digital transformation sweeping the world has meant that it has become impossible to keep a good track of the contracts, transactions and their records. Here is where blockchain comes in.

So, what is blockchain? The blockchain (or distributed ledger) is the technology that powers the digital currency bitcoin. It is an open, distributed ledger that can record transactions between two parties in an efficient and verifiable manner. One can imagine blockchain as a giant spreadsheet that runs on millions of computers. The blockchain is distributed, open source and everyone can see what is going on.

In the blockchain world contracts are embedded in the digital code. This code is stored in transparent, shared databases where they are protected from deletion, revision, and tampering. In this world, every agreement, every process and every transaction has a digital record and signature that can be identified, validated, stored, and shared. Futurists anticipate that the need for intermediaries like lawyers and bankers is likely to disappear. Transactions are likely to become frictionless.

There are many new uses for blockchain that are emerging almost every day. This new way of transacting could support business responsibility in many ways by supporting green supply chains, measuring water use, emissions management and supporting the sharing economy.

1. Green supply chains: Suppose a farm field is certified as organic. This certification enters the blockchain as a contract. When the produce is moved to another intermediary, the contract containing details of the produce is passed on to the intermediary. This link continues till the food item or a product manufactured out of it reaches the customer. The customer can have a complete record of all the ingredients in the product providing assurance that the product contains what it is supposed to.

2. Water management: Companies draw water from local sources for their operations. Water withdrawal can be recorded on distributed ledgers. Water additions and withdrawals can then be tracked at different places within the factory premises using smart meters. This recording could enable companies to track their water usage efficiently and effectively.

3. Emissions: Companies that generate fossil CO2 could deposit a specified amount for every tonne generated in the blockchain ledger. The deposited funds could be held in escrow. The funds would remain in the escrow account till they are redeemed by a party anywhere else in the world who successfully segregates a ton of CO2. Reforestation or industrial CCS (carbon capture and sequestration) are the primary means of achieving sequestering. In this system, every ton of CO2 emission is individually accounted. Financial incentives would be created to isolate the CO2 in a safe manner. After all the accounts are balanced then zero net emissions of CO2 would have been achieved.

4. Sharing economy: The sharing economy reduces resource wastage and minimises recycling. Much of the sharing economy, today, is characterised by large centralised organisations that enable aggregation. The blockchain technology could provide a disaggregated peer-to- peer system that could eliminate the need for physical offices and assets. This would enable these platforms in a different way, by ensuring that buyers and sellers could interact directly with one another, without passing through any centralised middleman. Buying and selling contracts would then be fulfilled through transactions recorded through the blockchain technology.

5. Smart villages: Smart Villages typically run on a microgrid powered by renewable energy. The microgrid needs to allocate electricity efficiently. Smart metering coupled with blockchain ledger recording can help immensely. The power demand at home would be recorded and the demand matched against the supply that is available. The matching mechanism would provide for an efficient resource allocation. This system is in fact being piloted in several parts of the world.

6. CSR spending: Companies in India are mandatorily required to spend 2% of their average net profits on CSR. Thus the 2% spend by corporations becomes a contract between the government and the company that needs to be executed. Rather than the opaque systems that exist today, we could have information on every activity undertaken by the company made available to all. The activities can be tracked and authenticated.

Blockchains are here to stay. It is incumbent upon companies to use the technology smartly to reap the many benefits of – secure transactions, faster dissemination, equal availability of information, and help companies adopt responsible stewardship.

ABB uses smart tech to solve humanity’s most pressing challenges

Carbon emissions are a significant cause of worry for India and the world. To solve this we need renewable energy. But, that’s not all, significant savings in emissions can be achieved with the help of energy efficiency. ABB is an interesting company because 57% of its product portfolio is based on renewable energy and energy efficiency products. According to ABB advanced technologies enabling the Fourth Industrial Revolution are our best hope of addressing the climate emergency.

ABB is an engineering and technology company that drives the digital transformation of industries. This 130+ year old company operates in more than 100 countries with about 110,000 employees across the globe. ABB has been present in India for over a century and is a listed company with multiple manufacturing locations, global feeder factories and development & engineering centers. ABB has four businesses, Electrification, Industrial Automation, Motion, and Robotics & Discrete Automation. The company believes that for it to lead transformation in the 4th industrial revolution it needs to build a strong foundation based on Health, Safety, Integrity and Sustainability.

According to Sanjeev Sharma, CEO and MD ABB India, “Sustainability is not something extraneous and only aligned to current thinking but , it is core to our business for decades. We first focus on things that we can do to reduce our carbon footprint, then we focus on products and services that can help others.” He says, “In India we use up to 30% more energy to produce one unit of anything across sectors. Hence the first step companies need to take is to improve energy efficiency at every level. Changing to energy efficient motors for instance can increase cost savings between 20-30%. Our approach to reducing energy usage is increasing efficiency, making product elements more environment friendly and using digitalization. In addition, ABB has also developed high and medium-voltage switchgear with AirPlus™ technology, which is a ground-breaking eco-efficient gas mixture with 99.99% lower global warming potential (GWP).”

The energy portfolio of ABB therefore focuses on Smart cities, Smart transport, Smart living, and Smart distribution. Share of ABB’s eco-efficiency portfolio is at more than 57% of ABB revenues globally, and aims to be at 60% in 2020. Around the world, ABB operations are increasingly choosing to purchase certified “green” electricity and its facilities are installing on-site photovoltaic (PV) power plants to reduce environmental impact.

ABB impacts sustainability, by providing products and services to companies and cities to reduce their environmental footprint. This is very important because, around the world, expanding cities are under growing pressure to reduce pollution and congestion, while providing clean energy and water, as well as the necessary jobs, goods and services for their inhabitants to have a good standard of living. The only way to achieve this is to build smarter cities, using advanced technologies and systems.

A similar challenge is confronting industry, which must reduce its environmental footprint while at the same time becoming more productive and providing affordable power, goods and services to a growing global population. Here, digitally enabled automation and robotics solutions hold the key to sustainable energy, manufacturing and production. Sanjeev Sharma says, “ABB Ability™ solutions collect and analyze data from across the industrial internet and provide customers with automated insights into their processes and equipment in order to increase the uptime, speed and yield of their operations, in the most energy efficient way. ABB’s smart technologies are helping to meet many of the underlying targets of the Sustainable Development Goals (SDGs)”

ABB India, is also following the global path by focusing on technological innovations and solutions that serve these needs. For instance, the company has implemented the Surat smart city water management system. Here ABB technologies have enabled the digitalization of the entire water management system of Surat with its flowmeters solution to measure water consumption in real-time. The city of Surat is known for its resilience and is the textile hub of the country – textile industry requires a lot of water. ABB’s smart digital flowmeters close to 300 in number help track, measure and optimize water consumption real-time and enable city corporation to manage water more efficiently.

Some ABB projects also have large social footprint. The Kaleshwaram Project, a first-of-its-kind lift irrigation project in the world, includes a range of ABB technologies including motors and switchgears. The Kaleshwaram Lift Irrigation project brings drinking water and irrigation to the backward areas of Telangana and helps restore the ground water level to its original state. In addition to this, ABB’s soft starter solution was used to manage huge motors and high-voltage power systems for the Mahatma Gandhi Kalwakurthy Lift Irrigation Scheme.  Years of severe drought had created a water crisis in the Mahbubnagar region in Telangana, a state in southern India where half the population depended on agriculture to earn a living. The water table had virtually depleted and the monsoon rains only lasted three to four months a year. The only option for providing adequate water for farming and drinking was to pump it from the Krishna River to a reservoir nearly 300 meters above. From there, through the gravity-driven Mahatma Gandhi Kalwakurthy Lift Irrigation Scheme”, the water was channelled through nearly a hundred kilometres of canals to the parched farms and more than 300 villages that were at risk of turning to desert.

The global consensus on climate change is driving demand for products, solutions and services that increase energy efficiency and reduce consumption of non-renewable resources. Technological innovation will play a critical role in meeting these needs – improving people’s living standards while simultaneously reducing their impact on the environment. With this in mind, ABB’s mission is fully aligned with global efforts to bring the Sustainable Development Goals (SDGs) within reach by 2030. While there is a moral imperative to support the SDGs, there are also material incentives. SDG-related opportunities involving building solutions, urban infrastructure, clean energy, energy efficiency and mobility are estimated to exceed $5 trillion
