Advancing environmental-economic accounting in the context of the system of economic statistics

3.1Introduction

The SEEA 2012 comprises two key volumes the SEEA 2012 Central Framework [23] and the SEEA 2012 Experimental Ecosystem Accounting [24]. This section describes the key components included in these volumes structured in terms of accounting for environmental assets, accounting for physical flows and accounting for environmental transactions.

Other SEEA publications have also been developed or are developing. SEEA Water [25] and SEEA Energy [26] provide specific accounting descriptions in these two areas with direct links to associated international recommendations for water and energy statistics. The SEEA Agriculture, Forestry and Fisheries (SEEA AFF) [27] applies the accounting structures and principles of the SEEA Central Framework to a sub-set of the economy, and a similar approach has been developed in the context of tourism activity [28]. Further, to respond to current areas of high policy interest, work has commenced on applying SEEA’s principles and structures to support discussion of oceans and biodiversity in particular aiming to highlight the connections between the environment and the economy in these contexts.

3.2Accounting for environmental assets

Accounting for environmental assets is at the heart of the SEEA. From a measurement perspective however, environmental assets can prove difficult to define and, commonly, varying terms and definitions are used without a clear understanding of the links to standard measures of economic assets as defined in the SNA. Double counting or measurement gaps are therefore real risks. The SEEA Central Framework brings increased clarity to this area of accounting.

Environmental assets are defined broadly to encompass the whole of the biophysical environment. Thus “environmental assets are the naturally occurring living and non-living components of the Earth, together constituting the biophysical environment, which may provide benefits to humanity” [23].

For measurement purposes this definition is considered from two different but complementary perspectives. In the first perspective various components of the biophysical environment are measured as individual environmental assets. These components include mineral and energy resources, soil resources, timber resources, fish and aquatic resources, other biological resources and water resources. Asset accounts that record the opening and closing stocks of these resources and the additions and reductions in stock are described in the SEEA Central Framework. The measurement scope of individual environmental assets is not limited to purely natural resources and hence includes, for example, timber resources in plantation forests. Coverage of both natural and cultivated environmental assets ensures that changes in the composition of environmental assets can be recorded.

The second perspective on the measurement of environmental assets is to consider how the environment functions as a system by separating the environment into various ecosystem assets including forests, wetlands and agricultural areas. Thus, in ecosystem accounting, for example, rather than focus only on the timber resources of a forest, also considered is the functioning of the forest reflecting the interactions among the trees, the soil, the water resources and the other characteristics (e.g. biodiversity) and processes and the suite of services beyond timber including air filtration, carbon sequestration and recreational opportunities.

To give effect to this wider, systems view in accounting terms requires a series of accounts to be developed. Thus, ecosystem accounting comprises:

Figure 2 shows how the concepts of ecosystem assets and ecosystem services are related in the ecosystem accounting framework.

Beyond the measurement of the physical stocks and flows of environmental assets, the SEEA provides guidance on their valuation. To support comparison and integration with standard economic and financial data, the valuation principles used in the SEEA are aligned with the exchange value concept applied in the SNA.

3.3Accounting for physical flows

Physical flow accounts are the most well-developed of the SEEA accounts and have been implemented in many countries. For example, at least 42 countries have implemented water accounts [29]. Physical flow accounts are also common for flows of water, greenhouse gas emissions and solid waste. Each physical flow account is balanced by virtue of using a single measurement unit (e.g. tonnes, cubic metres, joules) and by ensuring that all flows between the economy and the environment, and within the economy, are constrained to satisfy the supply-use and input-output identities.

The core logic of physical flow accounts was presented above in Fig. 1b. Each physical flow account considers, as appropriate, the flows of the relevant substance from the environment to the economy (natural inputs), within the economy (flows of products) and from the economy to the environment (residuals). Accounts for water and energy track all of these types of flows. Accounts for greenhouse gas emissions focus only on residual flows.

A unique aspect of the SEEA is its definition of the boundary of the economy. It is defined in such a way that the physical flows can be directly related to the monetary flows that are recorded in the measurement of GDP. GDP is defined by a production boundary, that is, the set of goods and services that results from production by economic units. The SEEA defines this production boundary in physical terms. The outcome is that direct relationships can be made between standard economic accounting measures such as output and value added, and physical measures such as water and energy use, and greenhouse gas (GHG) emissions.

This unique aspect may be particularly important where the physical data sets (e.g. GHG emission inventories) are commonly collected without consideration of the precise measurement scope of the economy.

Importantly, the physical flow accounts of the SEEA apply standard product, industry and institutional sector classifications such that economic data and environmental information can be readily compared. This allows straightforward and correct definition of productivity and intensity indicators where physical flows are compared to economic variables such as value added and output. Further, with physical data structure and scoped following the SEEA extensions to input-output tables are more straightforward thus supporting the derivation of footprint and similar calculations. The generic structure of SEEA physical flow accounts is shown in Table 1.

The application of supply and use recording principles for environmental flows supports a wide range of applications including linking to standard input-output tables to model the environmental effects of different economic activities and policy choices. Information from physical flow accounts also support a coherent recording of environmental pressures both in terms of pressures from resources use (e.g. water and energy) and in terms of the release of residuals such as GHG emissions, solid waste and wastewater. When combined with information on the changing condition of ecosystems, as described in an ecosystem condition, it is clear that accounting can provide the basis for an informed discussion about the links between economic activity and the environment.

3.4Accounting for environmental transactions

The predominant focus in natural capital accounting is on integrating environmental information into standard economic accounts. However, also of interest is the potential to glean information from standard economic accounts about activities undertaken by economic units that may be considered “environmental”.

To this end, the SEEA Central Framework defines the environmental activities of environmental protection and resource management as constituting a scope that can be used to classify various standard economic flows such as output, value added, investment and employment. The SEEA Central Framework defines environmental protection expenditure accounts to record expenditures by governments, households and businesses that have the purpose of maintaining or improving the environment. The SEEA Central Framework also defines the Environmental Goods and Services Sector (EGSS) and an associated set of indicators that may be used to provide ongoing estimates of output and employment in environmental activities as a share of overall economic activity.

This area of the SEEA also provides definitions for environmental taxes and environmental subsidies and similar transfers. Particularly at an international level, consistent definition of these types of variables permits an assessment of alternative policy responses.

Collectively, data on environmental transactions records society’s economic response to environmental issues and thus completes a picture on the links between the environment and the economy.

3.5Key outputs and applications

SEEA’s accounting data can be presented in a variety of ways. Most commonly, as for the national accounts, data are presented in the form of tables and aggregate indicators. Increasingly, especially for ecosystem accounting purposes, data are being compiled using earth observations and hence outputs in the form of maps are common. These outputs are of particular relevance in environmental assessments since commonly it is the location of the connection between economic activity and the environment which needs to be understood to allow for appropriate policy responses. Working from national averages may give some broad indications of the nature of changes but these may hide considerable variation that needs to be accommodated.

Data from SEEA accounts can support policy and decision making in a range of ways. These include:

It is likely that the greatest benefit from the development of SEEA accounts will emerge when a reasonable time series of information is developed that shows patterns of change over time. This is not currently the case for most accounts in most countries. Nonetheless, structural information at a given point in time about the links between the environment and the economy remains important information to support discussion of both economic and environmental policy.

4.1Introduction

The breadth of the SEEA set of accounts highlights the breadth of the connection between the environment and the economy and the reality that the economy is nested in the environment. Although the implementation of SEEA accounts does not have the breadth of coverage of countries and years as the SNA, there have been rapid advances in the course of the past decade and many examples of connections to policy and monitoring. This section highlights just some of these advances.

4.2Summary of SEEA uptake

With the adoption of the 2030 Agenda for Sustainable Development [30], countries increasingly recognize that economic growth is not enough to ensure well-being for their citizens. The Sustainable Development Goals clearly recognize the crucial importance of interconnectedness and integrated nature of the goals in ensuring that the purpose of the new Agenda is realized. This requires integrated policies that need to be supported by integrated information system. In this context, given the integrated nature of the approach has been increasingly recognized as an important framework to support the SDG.

Increasingly the SEEA EEA is being recognized as an important framework to measure biodiversity and its relationship with the economy. Regular communication is under way between the statistical community and the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) to ensure that the IPBES Value Assessment report currently under preparation and the SEEA EEA come out with consistent recommendations to countries.

More recently, the current discussions leading to the development of the Post 2020 Biodiversity Framework and the associated monitoring framework, have identified the SEEA as an important contribution of the statistical community to the derivation of indicators supporting biodiversity policies. A process is now under way, led by the Secretariat of the Convention on Biological Diversity, which requests that national statistical offices (i) contribute to the development of the monitoring framework, in light of the development of the SEEA EEA, and (ii) actively engage in the implementation of the framework. This is a great opportunity for the statistical community to be able to contribute to the development of such a framework from the start of the process.

Upon the adoption of the SEEA Central Framework and the release of the SEEA EEA in 2013, an ambitious implementation strategy was adopted by the Statistical Commission. The strategy included two implementation targets: 100 countries implementing the SEEA Central Framework and 50 countries implementing the SEEA EEA. At that time, those targets seemed difficult to reach, however seven years later we are very close to reaching the targets. The uptake of the SEEA in countries has been phenomenal. According to the 2017 Assessment [29], sent to all National Statistical Offices, 69 countries had programmes on environmental-economic accounting. This corresponds to a 28 per cent increase in the number of countries with a programme on environmental accounting compared to the 2014 Global Assessment [31]. The percentage increase in the number of developing countries implementing the SEEA was even higher, with almost a 39 per cent increase between the 2014 and 2017 Assessments. In addition to the 69 countries with programmes, 22 countries indicated they were currently planning a programme on environmental-economic accounting. Almost all countries are planning to begin their programme and start compilation before 2020.

According to our estimation, currently about 92 countries are implementing the SEEA Central Framework. We obtained this figure through informal consultation with the United Nations Regional Commissions, international agencies, donor agencies, and SEEA experts.

The global assessment has been administered every 3 years and has served as a tool to monitor the progress of implementation of the SEEA. With the adoption of SDG indicator 15.9.1 (Number of countries implementing the SEEA), the Committee of Experts on Environmental Economic Accounting (UNCEEA) decided to run a detailed global assessment every three years providing a broad range of information on implementation, including its funding, stakeholder involvement, type of accounts compiled and periodicity, etc. and have a reduced format global assessment for the intervening years to support reporting on the SDG indicator.

The uptake of the SEEA EEA has been even more remarkable: from a zero base in 2013, by 2019 there were over 40 examples of ecosystem accounting programs with applications in, and participation from, all sectors – public, private, academia and civil society [32].

The United Kingdom and the Netherlands have published the most comprehensive ecosystem accounts to date. Both countries’ accounts include detailed maps and physical and monetary accounting tables showing a consistent application of concepts and methods. In other countries, progress is being made towards comprehensive SEEA EEA accounts. For instance, in South Africa national ecosystem accounts have been developed for the extent and condition of rivers [33]. Australia has published two national and several sub-national accounts. Other countries with published accounts include Canada, China, Costa Rica, Colombia, Indonesia, Italy, Japan, Norway, Mexico, the Philippines, Rwanda, Spain and the United States; and supranational accounts have been developed for the European Union.

As part of the EU funded project Natural Capital Accounting and Valuation of Ecosystem Services (NCAVES) project, Brazil, China, India, Mexico and South Africa are compiling ecosystem extent accounts, ecosystem condition accounts and selected ecosystem services in physical and monetary terms at the national as well as subnational level. The NCAVES project has been instrumental in establishing a programme on ecosystem accounts in these countries and in building capacity towards a long-term regular development of ecosystem accounts.

4.3Country examples

4.3.1Energy accounts in Costa Rica

The energy intensity of economic activities can be estimated by calculating the ratio between final energy use and value added.11 This indicates how many units of energy (joules) are required to generate a million units of output (in Costa Rican colones) and is therefore a measure of the energy efficiency of economic activities. Figure 5 shows, the energy intensity of the Costa Rican economy has decreased since 2011, though 2016 saw a slight increase of 0.5 per cent over the previous year [34]. Since 2013, the electricity and water supply sectors have become more efficient in their energy use, but agriculture has trended in the opposite direction. Because of the consistency between the environmental accounts and the national accounts, such trends can be further analysed by, for instance, undertaking a structural decomposition analysis to assess the drivers of change.

4.3.3Mexican extent accounts

The extent account, such as the one for Mexico shown in Fig. 6, describes the various types of ecosystems that are distinguished within an area and how they change over time. Countries have used different approaches to compiling ecosystem extent accounts taking data availability and policy demands into account, for example, using vegetation maps as the basis for the extent account; combining land cover maps with data on habitats/vegetation; and taking the types of land uses and ecosystem services supplied into consideration.

The example from Mexico [36] also shows a map (Fig. 7) of the distribution of various types of ecosystems. The table describes changes in the extent of ecosystems between 2002 and 2015. The potential for mapping data is a key feature of all ecosystem accounts.

4.3.4Managing peatlands in the Netherlands

Consisting of plant remains (about 10 per cent by weight of peat) and water (90 per cent), peatlands are considered to be one of the most challenging ecosystems on the planet to manage. Not only do their swampy conditions make access difficult, but their high water table prevents the cultivation of most crops. This means that drainage is essential in order to use them for agriculture or other extractive purposes. However, while drainage allows for agricultural activities on peatlands, it also exposes the organic matter in the soil to oxygen in the atmosphere. The oxidation of organic matter leads to CO2 emissions, and drainage also leads to sunken grounds which leave the drained peatlands vulnerable to floods.

In the Netherlands [37], peatlands cover around 8 per cent of the land area and are mainly used for dairy farming. Among farmers, there is a tendency to prefer lower water tables which allows easier access to the meadows and favours the growth of grass. The resulting national CO2 emissions caused by the drainage, are around 6 to 7 million tonnes CO2 per year (some 4 per cent of the national total CO2 emissions). Their management has multiple dimensions ranging from generational farming, to income dependency for farming peatlands, to a reliance by some of the food processing industry who are dependent upon the milk produced. This means that farmers can be reluctant to acknowledge the externalities of peatland drainage, which not only include CO2 emissions but also the maintenance of infrastructure (roads, dykes, sewage systems) affected by continuous soil subsidence in drained peatlands, among others. In all, these externalities have been estimated to amount to up to 1000–1500 euro per hectare of drained farmland per year.

Unfortunately, there is no technical solution to the problem that allows farmers to drain the peatlands without producing significant externalities. Therefore, trade-offs in landscape management are unavoidable. Government intervention can reduce the externalities placed upon society, but at the expense of farmers’ income. Thus, decision making on the use of natural resources usually involves balancing diverging interests and considering social, environmental and economic dimensions of different options.

At the time the SEEA EEA accounts were published, a broad stakeholder engagement process had been started by the Netherlands government to discuss climate change targets and measures to be taken to reach these sectors. Peat management featured prominently in the discussion on how the agricultural sector could reduce GHG emissions. The Netherlands carbon account was published just prior to the start of these negotiations. The account showed clearly the contribution of peatlands to national CO2 emissions (Fig. 8). It also showed that, at a micro-level, profits from farming were smaller than the monetized costs of CO2 emissions and resulting damages. As a result, in the final, agreed sectoral climate change mitigation plan, the focus shifted to taking land out of production and increasing water levels to the surface to avoid all CO2 emissions in these areas, while at the same time further testing technical approaches at pilot scale. An amount of 250 million euro has been reserved for converting drained farmland to undrained land use, including nature areas and no-drainage agriculture. Furthermore, an initial law has been proposed to further support and incentivize farmers to stop farming in peatlands.

4.3.5European Union ecosystem services accounts

Ecosystem service supply and use accounts record the supply of ecosystem services as well as their corresponding use and beneficiaries, classified by economic sectors used in the national accounts. Ecosystem services are defined in SEEA EEA as the contribution to benefits, rather than as the benefits themselves, in order to avoid double counting. For example, an agricultural crop such as corn or maize is already recorded in the national accounts. Moreover, corn is the product of combining human capital (in the form of labor), produced capital (machinery) and natural capital (the cropland). The objective of the services accounts is to isolate the contributions of nature to the production of the crop visible. In addition, by expanding the SNA production boundary, the accounts also recognize a range of ecosystem services that lead to benefits that are not currently recognized in the SNA such as global climate regulation and air filtration.

Work on measuring ecosystem services for the European Union (EU) [38] followed three main steps:

• • First, a range of ecosystem services is spatially modelled resulting in maps showing where they are supplied

• • Second, each individual service is valued (e.g. by multiplying the physical unit with a relevant unit price say as stumpage value for timber provisioning, social cost of carbon for carbon sequestration, or avoided damage costs for flood protection).

• • Third, the maps of the individual modelled services (in physical and monetary terms) are overlayed (i.e. crossed) on the ecosystem extent map. The results are aggregated, showing in the form of a supply and use table which ecosystems provides what services, and how benefits from them.

The data in Fig. 9 shows, for example, that woodland and forests provide five of the six services that were modelled, while urban ecosystems provide three services. The figure also shows that woodland and forests provide the largest value on a per km2 basis, followed by wetlands. The use table describes which economic sector benefits from the supplied ecosystem services.

These data can also be shown in the form of maps as in Fig. 10.

Ecosystem service supply and use accounts are used for informing a range of policies. The accounts can be used for land use planning purposes as they allow assessment of trade-offs under alternative scenarios. These accounts have also been used to inform policy instruments such as eco-compensation standards, or Payment for Ecosystem Services schemes.

4.4Connections to international policy and reporting

The SEEA EEA describes a relatively comprehensive set of data, with its broad coverage of organizing information on ecosystems of all types considering changes in extent and condition, on flows of ecosystem services in physical and monetary terms, and on the value of ecosystem assets and their degradation. Given its intention to support comparable measurement in these areas over time and across countries, the SEEA can provide a robust framework to support a range of global environmental and sustainability initiatives. Examples include:

Of particular note, is that the SEEA is well-positioned to support the post-2020 biodiversity framework emerging from the 2020 Convention of Biological Diversity Conference of Parties meeting. The information generated by the SEEA can be used to develop indicators for monitoring progress toward the pact’s goals. An assessment report from the UN Environment World Conservation Monitoring Centre and United Nations Statistics Division shows that 61 of the current Aichi Target indicators are fully or partially aligned with the SEEA [42] and the UNCEEA has identified at least seven targets that currently lack indicators for which the SEEA could provide needed information.

The SEEA can provide valuable information for countries, helping to both prioritize conservation efforts and assess implementation at the national level. Its integrated systems approach can clarify the major drivers of biodiversity loss and ecosystem changes, identify key trade-offs, and support the development of “win-win” conservation approaches. Ecosystem accounts used in combination with information on expenditures also can provide decision-makers with a clear picture of the return-on-investment from biodiversity protection. The SEEA also can be used to measure level of effort through tracking expenditures on conservation efforts in both the public and private sectors.

4.5Connections to corporate developments

Work on the development of the SEEA has been largely driven from the perspective of national governments and providing official statistics on the nature of the aggregate level linkages between the economy and the environment. However, as the spatial approach to measurement becomes more the reality and considering location becomes common practice, it is clear that sub-national and community level considerations need to be encompassed. Through ecosystem accounting, work on the SEEA has been connected to work at the corporate level concerning business dependencies and impacts on the environment.

Of particular note are links that have been made between the SEEA and the Natural Capital Protocol and to various natural capital accounting approaches that have developed in the corporate sector, including environmental profit and loss approaches and the corporate natural capital accounting approach. Further, there are now examples of the application of the SEEA at corporate level that provide a basis for further discussion (see, for example [43]).

Recent engagement with the business community around the SEEA,22 has shown the potential for the business community to work with the official statistics community to enrich the information set and hence underpin the joint management of the environment as a shared resource.

4.6Analytical possibilities and other extensions

Over the past decade the interest in integrating environmental factors into economic models has grown. It is increasingly recognised that SEEA accounts can provide the robust and authoritative framing for environmental data for integration into standard economic models. For example, building on long established techniques of environmental-economic modelling (for a summary of work in this area see SEEA Applications and Extensions), the Inter-American Development Bank has been developing an Integrated Environmental-Economic Model (IEEM) to support project assessment in Latin America and the Caribbean [44].

Further, the potential of the SEEA to support analysis has been demonstrated in Indonesia in the development of scenario analysis. The Ministry of National Development Planning in Indonesia, in collaboration with the World Bank and other development partners, recently introduced the Low Carbon Development Initiative into the country’s National Medium-Term Development Plan 2020–2025 [45]. To facilitate a better understanding of the feasibility of low-carbon growth, scenario modelling was conducted using environmental accounting approaches based on the SEEA. This included the use of land cover accounts, land extent accounts and peat accounts developed at the national and provincial levels. These accounts, coupled with the incorporation of an energy and water balance in the model, allowed for the estimation of the impact of natural resource availability and ecosystem service provisioning on economic productivity – and hence on forecasts for GDP growth and other macroeconomic performance indicators. Figure 12 illustrates that GDP growth increases with the extent of ambition of policy measures introduced in support of low-carbon development.

Finally, in the context of the SDGs there is renewed interest in multiple capital based approaches to considering development and hence the field of wealth accounting is gaining higher profile. The SEEA is seen as the statistical standard that can support measurement of the natural capital component within wealth accounts and hence support analysis of changes in wealth and links to development outcomes. In a multiple capital context, SEEA is also being used to support the TEEB Agriculture and Food evaluation framework [46] and the UN World Tourism Organization project on measuring the sustainability of tourism [28].

5.1Challenges and opportunities for NSOs

Through the developments in the SEEA over the past decade a clear role for official statistics has emerged in support of improved discussion of the links between the environment and the economy, and of sustainability more widely. In most countries SEEA accounts cannot be compiled solely by the National Statistical Office (NSO) since often environmental data are collated in other agencies. Nonetheless, it should be recognised that:

Notwithstanding the potential for NSOs to contribute to the discussion of sustainability through the SEEA, there remain a range of challenges in compiling these accounts. Some of these challenges concern the availability and coherence of environmental data which, as noted, will commonly be held in multiple agencies using a range of classifications and definitions. The related and potentially larger challenge is working across multiple agencies and securing appropriate arrangements for the exchange and publication of data. While these are undoubtedly large challenges, they are ones that NSO have commonly confronted in the development of economic and social statistics. What is therefore required then is establishing a clear demand for SEEA accounts that in turn can secure the appropriate level of resourcing to maintain and build an ongoing program of work. By way of example, establishing a clear demand for accounts would help to support the development of a national spatial data infrastructure wherein the wide variety of spatial data can be appropriate referenced and stored.

5.2Motivating the way forward

The 51st session of the United Nations Statistical Commission (UNSC) in March 2020 gave the United Nations Committee of Experts on Environmental-Economic Accounting (UNCEEA) an opportunity to present the progress made over the past year. The UNSC recognised the importance of the SEEA in supplying a common measurement framework for the post-2020 global biodiversity framework and the work done on mainstreaming the SEEA as the statistical framework to support various initiatives, including the use of SEEA for country-level reporting on the SDGs.

UNSC also recognised the significance of the revision of the manual on ecosystem accounting that is due to be completed in March 2021. It “emphasized the urgency of providing a standardized methodology for ecosystem accounting that reflects the revision and reinforces the role of national statistical offices as data stewards; and supported the aspiration to elevate the revised SEEA Experimental Ecosystem Accounting to SEEA Ecosystem Accounting”.33 The endorsement for the developments in the SEEA was also evident in the UNCEEA’s High Level Panel held in parallel with the UNSC meeting.

Advances in the SEEA have also highlighted the relevance of improvements in accounting for natural capital in advancing economic statistics. One of the key areas for consideration in the revision of the SNA2008 that has just commenced is the measurement of sustainability and well-being. The developments in the SEEA, especially concerning ecosystem assets and their associated benefit streams, will be of direct relevance in this process.

While there are some excellent advances to be recognized, it is also clear that the biodiverse, healthy ecosystems which provide essential contributions to people remain under significant pressure. And it remains the case that the contributions provided by our natural capital are usually taken for granted when making important economic decisions. Tragically, it is often the poorest and most vulnerable populations that are most directly dependent on the benefits of biodiversity and healthy ecosystems for their daily needs. We can no longer afford to ignore our dependence on the environment, our natural capital. Accounting for it is part of the pathway forward.
