A note on sustainable management accounting (SMA) for advanced management accounting study
Describe 5 main ideas on the topic of sustainable
management accounting and then briefly describe how the topic has evolved over
the last 15 years. Also suggest 3 main academic theories employed to study this
topic (with references in Harvard reference format). Lastly, briefly discuss
the different evolutionary paths of sustainable management accounting practices
in the geographical regions of North America, Continental Europe and South East
Asia.
Five Main Ideas in Sustainable Management
Accounting
Sustainable
management accounting (SMA) extends traditional cost and decision-making tools
by embedding environmental and social impacts alongside financial performance.
- Triple
bottom line integration: SMA tracks economic,
environmental, and social performance together, rather than treating
financial results as the sole measure of success.
- Full
cost / sustainable cost accounting: this approach attaches
monetary values to externalities such as waste, emissions, and resource
depletion, so hidden environmental costs become visible in
decision-making.
- Non-financial
and integrated disclosure: SMA feeds into
sustainability and integrated reporting, combining financial statements
with narrative and quantitative environmental/social indicators for
external stakeholders.
- Decision-support
for strategy: SMA techniques (e.g. life-cycle costing,
material flow cost accounting, environmental performance indicators) are
used internally to guide investment appraisal, pricing, and process
redesign.
- Data
and measurement complexity: a recurring theme is the
difficulty of collecting reliable environmental and social data compared
with financial data, which limits comparability and standardisation.
How the Topic Has Evolved Over 15 Years
Fifteen years ago,
sustainability accounting and environmental accounting were largely used
interchangeably as an emerging, loosely defined field. Over time, the two
strands have separated: sustainability accounting has moved closer to formal
reporting frameworks and regulatory compliance (driven by standards such as GRI
and, more recently, IFRS Sustainability/ISSB standards), while environmental
accounting has become a more technical specialism addressing carbon accounting,
biodiversity, and ecological measurement. This reflects a broader shift from
voluntary, image-driven disclosure toward institutionalised, regulation-driven
practice.
Three Main Academic Theories
Three theories
dominate this research area, and they are often treated as complementary rather
than competing lenses:
1.
Legitimacy theory – firms disclose sustainability information
to maintain a "social license to operate," justifying activities
against societal norms and expectations (Suchman, 1995; Deegan, 2019).
Suchman, M.C. (1995) Managing legitimacy: strategic and institutional
approaches. Academy of Management Review, 20(3), pp.571–610.
2.
Stakeholder theory – organisations must account for the
interests of a broad range of stakeholders, not just shareholders, which drives
transparency and engagement in sustainability reporting (Freeman, 1984).
Freeman, R.E. (1984) Strategic management: a stakeholder approach.
Boston: Pitman.
3.
Institutional
theory – adoption of SMA
practices is shaped by regulatory pressure, industry norms, and isomorphism
across organisations (DiMaggio and Powell, 1983).
DiMaggio, P.J. and Powell, W.W. (1983) The iron cage revisited: institutional
isomorphism and collective rationality in organizational fields. American
Sociological Review, 48(2), pp.147–160.

Stronger
institutional and regulatory push (EU directives, stakeholder-oriented
governance traditions), so institutional theory explains adoption patterns
better, with sustainability accounting more embedded in mandatory reporting
regimes. |

Adoption often
linked to global supply-chain pressure and institutional isomorphism from
multinational buyers and international standards, with legitimacy-seeking
behaviour common among firms operating in emerging-economy institutional
contexts. |

Provide a simple illustrative example with calculation on
sustainable management accounting practice.
Illustrative example: reducing packaging
waste
A beverage company
produces 100,000 bottles each year. It is considering switching from a
heavier plastic bottle to a lighter recyclable bottle. Sustainable management
accounting captures both the usual financial cost and environmental-cost
information, including material losses and waste disposal.
Step 1: Current practice
|
Item |
Calculation |
Annual cost |
|
Plastic
purchased |
100,000×$0.30 |
$30,000 |
|
Production
waste: 10% |
10,000×$0.30 |
$3,000 |
|
Waste-disposal

10,000×$0.05 |
$500 |
|
Energy for
production |
100,000×$0.08 |
$8,000 |
|
Total relevant
annual cost |
$41,500 |
The key insight is
that defective plastic is not merely a disposal issue: the firm also loses the
original purchase cost of the plastic, which conventional accounting may bury
within general production costs.
Step 2: Sustainable alternative
The lighter bottle
raises the material price but reduces waste and energy use.
|
Item |

|
Plastic

100,000×$0.32 |
$32,000 |

3,000×$0.32 |
$960 |
|
Waste-disposal

|

production |
100,000×$0.06 |
$6,000 |
|
Total relevant
annual cost |
$39,110 |
Step 3: Decision-relevant result
Annual saving
=$41,500−$39,110=$2,390
Although the
sustainable bottle costs more per unit, its lower waste and energy consumption
produce an annual cost saving of $2,390. The waste quantity also falls
from 10,000 to 3,000 bottles:
Waste reduction rate
=((10,000−3,000)/10,000)×100%=70%
This is a simple
application of material-flow cost accounting: managers trace physical inputs,
product output, and non-product output (waste), then attach costs to each flow
to support a financially and environmentally informed decision.
Are sustainable management accounting and environmental
management accounting the same topic?
Short answer
No. They overlap,
but they are not exactly the same topic. Environmental
management accounting (EMA) is usually narrower: it supplies internal managers
with monetary and physical information on environmental matters such as energy,
water, materials, waste, emissions, and related costs.
Sustainable
management accounting (SMA) is broader. It extends the environmental and
economic focus of EMA to include social impacts and wider sustainability
objectives, often framed through economic, environmental, and social
performance.

For example,
calculating the material cost and disposal cost of plastic waste is EMA.
Adding employee welfare, supplier labour standards, and community effects to
the same investment appraisal makes it SMA. Some business literature
uses the terms loosely or interchangeably, but academic research increasingly
distinguishes them to avoid treating environmental issues as the whole of
sustainability.
Highlight 5
main ideas on the topic of Material flow cost accounting?
Material Flow Cost Accounting
(MFCA) is an environmental management accounting technique that traces material
and energy flows in physical and monetary terms. Its purpose is to identify
inefficiencies, reduce material losses, and improve both environmental and
financial performance. It is associated with ISO 14051.
Five main ideas
1. Trace
material and energy flows MFCA follows materials and
energy through each major stage of an operation, such as purchasing, storage,
production, packaging, and waste treatment. These stages are often called quantity centres. The aim is to
understand where inputs go and how they are transformed.
2. Measure
both products and material losses MFCA distinguishes between:
o
Positive outputs, such as finished products.
o
Negative outputs, such as scrap, defects, waste,
emissions, rework, and material evaporation.
This
is important because conventional accounting may treat waste as an overhead,
whereas MFCA makes the quantity and location of the loss visible.
3. Link
physical data with monetary data Material flows are first
measured in physical units, normally kilograms, tonnes, litres, or units. Costs
are then attached to those flows. The analysis can include material costs,
energy costs, processing or system costs, and waste-management costs.
4. Assign
the real cost of losses MFCA does not calculate only the
purchase price of wasted materials. It also considers the processing, labour,
energy, storage, and waste-treatment costs associated with those materials.
Therefore, a small quantity of scrap may represent a much larger financial loss
than its purchase price suggests.
5. Support
environmental and financial improvement The final
objective is to identify improvement opportunities, such as reducing defects,
improving production yields, redesigning products, changing materials,
improving inventory control, or reducing energy use. MFCA supports decisions
that can simultaneously reduce environmental impacts and operating costs.
Simple example
If a factory purchases 1,000 kg
of material and produces 800 kg of saleable products, the remaining 200 kg is
not merely “waste.” MFCA investigates where the 200 kg was lost and assigns to
it the relevant material, energy, labour, processing, and disposal costs.
Management can then determine whether reducing the loss would be financially
worthwhile.
