The SEEA as a system
The SEEA consists of a coherent, consistent and integrated set of tables and accounts each of which focus on different aspects of the interaction between the economy and the environment or on the changing state of the environment. The tables and accounts are based on internationally agreed concepts, definitions, classifications and accounting rules.
There are four main types of accounts in the SEEA framework. These accounts can be integrated with the existing monetary stock and flow accounts of the SNA:
2. Functional accounts for environmental transactions;
3. Asset accounts in physical and monetary terms; and
4. Ecosystem accounts.
The first three types of accounts form the core of the SEEA and are known as the accounts of the SEEA Central Framework. Ecosystem accounts will be described in a second part of SEEA known as SEEA Experimental Ecosystem Accounts. The four main types of accounts are briefly described below.
Physical flow accounts record flows of natural inputs from the environment to the economy, flows of products within the economy and flows of residuals generated by the economy. These flows include water and energy used in production (e.g. of agricultural commodities) and waste flows to the environment (e.g. solid waste to landfill).
Functional accounts for environmental transactions record the many transactions between different economic units (i.e. industries, households and governments) that concern the environment. The relevant transactions are identified by first defining the set of environmental activities, i.e. those activities that reduce or eliminate pressures on the environment and that aim to make more efficient use of natural resources. Examples include investing in technologies designed to prevent or reduce pollution, restoring the environment after it has been polluted, recycling, conservation and resource management. Environmental activities are classified as being either environmental protection activities or resource management activities.
Asset accounts in physical and monetary terms measure the natural resources available and changes in the amount available. Asset accounts focus on the key individual components of the environment: mineral and energy resources; timber resources; fish/aquatic resources; other biological resources; soil resources; water resources; and land. They include measures of the stock of each environmental asset at the beginning and end of an accounting period and record the various changes in the stock due to extraction, natural growth, discovery, catastrophic loss and other reasons.
The compilation of asset accounts in physical terms can provide valuable information on resource availability and may help in the assessment of sustainability. A particular feature of the SEEA asset accounts is the estimation of depletion of natural resources in physical and monetary terms. For non-renewable resources the quantity of depletion is equal to the quantity of resource extracted but for renewable resources the quantity of depletion must take into account the underlying population, its size, rate of growth and associated sustainable yield.
Ecosystem accounts are a developing area and not part of the SEEA international statistical standard. Ecosystems are areas containing a dynamic complex of plant, animal and micro-organism communities and their non-living environment interacting as a functional unit. Ecosystem accounts are structured to summarise information about these areas, their changing capacity to operate as a functional unit and their delivery of benefits to humanity.
The benefits received by humanity are known as ecosystem services. They are delivered in different forms and are grouped into three broad categories. The first category of ecosystem services is provisioning services. These are the benefits received from the natural inputs provided by the environment such as water, timber, fish and energy resources. The second category is regulatory services. These include the benefits provided when an ecosystem operates as a sink for emissions and other residuals, when an ecosystem provides flood mitigation services or when an ecosystem provides pollination services to agriculture. The third category is cultural services. These are the benefits provided when an ecosystem such as a forest, provides recreational, spiritual or other benefits to people.
Each of the different types of accounts is connected within the SEEA framework but each focuses on a different part of the interaction between the economy and the environment. Examples of the relationships between the different accounts include:
These examples serve to highlight the many and varied relationships between the accounts, each taking a different perspective. Throughout the SEEA these relationships are supported by the use of common concepts, definitions and classifications.
One of the most difficult aspects of environmental decision-making is how to make trade-offs between the environmental assets that deliver a range of non-market goods and services, including ecosystem services, against development alternatives for which there are clear economic values. The SNA and the SEEA Central Framework include the value of environmental assets that have direct economic values. For example land, timber, fish, minerals and fossil fuels are included in the national balance sheet(footnote 1) . Valuation in the SNA and the SEEA Central Framework is based on market transactions or, where these are unavailable, the net present value of future expected income resulting from the use of these assets is recommended.
However, some environmental assets and many ecosystem services are not transacted in markets, although the value of some services may be included in the value of goods and services traded in markets. For example, the value of pollination is captured in the value of agricultural crop production, while tourism operators derive income from the people visiting natural attractions such as Uluru and the Great Barrier Reef.
The development of standardised methods for identifying and separately distinguishing the value of environmental assets and ecosystem services is an on-going area of work in the SEEA Experimental Ecosystem Accounts. The recognition of the value of these assets and services will provide important information to decision-makers and enable comparisons between different development alternatives.
THE SEEA AS A CO-ORDINATING FRAMEWORK FOR ENVIRONMENTAL-ECONOMIC STATISTICS
The SEEA stands apart from individual sets of environmental statistics in a number of ways. While sets of environmental statistics are usually internally consistent, there is, usually for good reason, often little consistency between one set of statistics and another. Environmental statistics are often collected with a particular regulatory or administrative purpose in mind and the way in which they are structured is specific to this need.
In contrast, the SEEA is an integrated system of accounts in which, to the fullest extent possible, there is consistency between one account and another in terms of concepts, methods, definitions and classifications. In addition, implementation of such an integrated system aims for consistency across time. This is of the utmost importance in developing the comparable timeseries estimates that are necessary in informing the policy process. The final important difference between environmental statistics and the SEEA is the latter’s explicit goal of achieving compatibility with the economic information of the SNA, including that contained within satellite accounts of the SNA. This adds considerable value to both environmental and the economic information, as it facilitates their analysis within a common framework.
The SEEA is different from traditional sets of environmental statistics in important ways, but it also relies upon them for the basic statistics required in its implementation. Ideally, these statistics would be readily available in a format that allowed their direct incorporation into the system. For example, data on air emissions from industrial sources would ideally be classified according to the industrial classification used in the SEEA. This would allow their simple incorporation into physical flow accounts and combined accounts.
It is likely that over time, as the SEEA becomes better known and adopted, there will be changes to the way in which environmental statistics are collected and structured, and in particular the adoption of common classifications and definitions of concepts. For this to occur there must be a spirit of collaboration and respect between those producing environmental accounts and those collecting data. The former group must understand that collecting data for environmental accounts may be a secondary concern for those responsible for providing information to, for example, a regulatory programme. The latter group must be convinced of the importance of having highly structured and consistent data within an accounting framework. The SEEA can serve as a guiding framework for the development of environmental information systems that are more compatible with economic statistics.
SEEA DEVELOPMENT AND IMPLEMENTATION
The ABS has been working closely with a range of institutions nationally and internationally on the development and implementation of environmental accounting. In Australia, the ABS, the Department of Sustainability, Environment Water, Population and Communities and the Bureau of Meteorology are collaborating on the National Plan for Environmental Information (NPEI), the State of the Environment Report as well as the planning for national environmental accounts. The NPEI is a particularly important initiative as environmental accounts must be underpinned by regular and reliable environmental information. Also at the national level the ABS is working with the Department of Resources Energy and Tourism and the Department of Climate Change and Energy Efficiency on issues relating to the data needed for regular SEEA-based energy and greenhouse gas emissions accounts. At the state level the ABS has worked closely with the Queensland and Victorian governments in developing pilot land accounts, with a view to developing land accounts in other states as resources and data permit. The ABS is also contributing to the development of environmental accounting in the catchment management authorities as well as to research by academics into biodiversity, carbon and ecosystem accounting.
Internationally the ABS has been working with the international statistical community to develop the SEEA, chiefly through the process established by the United Nations Statistical Commission and the United Nations Committee of Experts on Environmental-Economic Accounting (UNCEEA). The UNCEEA is currently chaired by the ABS and has representatives from the national statistical offices of other countries as well as international agencies - Food and Agricultural Organisation, International Monetary Fund, Organisation for Economic Cooperation and Development, United Nations Statistics Division, and World Bank.
The development of ecosystem accounts for the SEEA has been a focus of research in recent times. This work is building on the SEEA Central Framework as well as Australian and international experience. For example, the United Kingdom’s National Ecosystem Assessment(footnote 2) a range of work by the European Environment Agency(footnote 3) , the development of the Common International Classification of Ecosystem Services(footnote 4) , the Australia Ecosystem Services: Key Concepts and Applications(footnote 5) and others in Australia and elsewhere. Much of this experience has been brought together through a series of international meetings of the Expert Group on Ecosystem Accounts, held most recently in Melbourne 16-18 May 2012(footnote 6) . The United Nations Statistical Commission at its 44th session held early in 2013 welcomed the work on SEEA experimental ecosystem accounting as an important first step in developing a statistical framework for ecosystem accounting and requested that the UNCEEA develop a program of further work to progress this topic.
