Savings levels due to conservation and improvement efforts

This KPI measures resource and cost reductions attributable to conservation or environmental-improvement initiatives. It links projects with changes in greenhouse-gas emissions, energy, water, materials and expenditure, allowing management to see which interventions deliver verified environmental value.

When to use it

• Answer the key performance question: “To what extent are we actively reducing the environmental impact of our business?”

• Include the KPI in the corporate social responsibility perspective.

• Compare realised savings with a credible baseline and project cost.

• Track whether reductions persist and whether activity or impact has shifted elsewhere.

Origins

The indicator developed from environmental management, eco-efficiency, energy conservation and management accounting. Organisations increasingly translated engineering reductions into environmental and financial performance measures. It is not a standard KPI with one inventor; credible use depends on the accounting boundary and the method used to estimate avoided consumption or emissions.

What it is

Perspective: Corporate social responsibility perspective.

Key performance question: To what extent are we actively reducing the environmental impact of our business?

The measure aggregates verified reductions produced by defined projects, such as lower greenhouse-gas emissions, water withdrawal, energy consumption, material loss or operating cost. Keep unlike physical units separate; do not add water, energy and emissions into one unlabelled total.

The KPI should distinguish absolute reduction from intensity improvement and avoided future growth. It is related to carbon footprint, water footprint and energy-consumption measures, but it focuses on attributable change rather than the organisation’s entire impact.

How to use it

Measurement

Define project boundaries, baseline period, business-as-usual counterfactual, units, emission factors and measurement window. Adjust for production volume, weather, acquisitions and operational changes. Account for rebound, leakage and double counting across overlapping projects.

Data collection method

Use meters, invoices, production data, engineering models and project records. Compare post-implementation performance with a normalised baseline, and document estimates when direct measurement is unavailable. Use independent verification for material public claims.

Formula

Savings = baseline resource use or cost − adjusted actual resource use or cost attributable to the conservation project.

Report each resource in its native unit and translate to money or emissions only with disclosed prices and factors.

Frequency

Quarterly tracking is common, but cadence should fit the project. Long initiatives may use interim milestones while retaining a one- or two-year verification period to confirm persistence.

Source of the data

Use utility and procurement records, environmental systems, meters, operations data, project accounts and documented calculations rather than relying only on manual self-report.

Cost/effort in collecting the data

Cost can be high where baselines are unstable, submetering is absent or multiple factors affect consumption. Proportion the measurement effort to materiality and claim risk.

Target setting/benchmarks

Projects differ too much for one generic benchmark. Set expected physical savings, cost, payback, confidence and persistence for each initiative, then evaluate the portfolio against environmental goals.

Example

In 2010, Nestlé reported an energy-target-setting initiative that identified more than 200 projects. The stated annual potential included about 1.3 million GJ of energy, approximately 88,000 tonnes of CO2, 1.9 million m3 of water and CHF 27 million.

Read these historical values alongside the stated baseline, boundary and verification method. “Identified” savings may represent forecast potential rather than independently verified realised reduction.

Top practical tip

Publish a savings register with baseline, method, owner, project cost, realised result, confidence and persistence. Compare lifecycle savings with lifecycle cost, and show forecast and verified savings separately.

Top pitfall

Do not claim every fall in consumption as project impact. Lower production, warmer weather, outsourcing or changed emission factors can create apparent savings, while rebound and leakage can move the burden outside the boundary.
