Environmental Performance Indicators

The process of selecting EnPI starts from a precise understanding of the environmental problems and monitoring objectives being addressed. Why do we want to measure environmental performance? The answer is a combination of some or all of the following:

• To ensure compliance with all relevant legislation and with specific requirements to which the company has made a public commitment.

• To improve performance and reduce compliance costs.

• To better understand environmental risks and minimize future costs.

• To communicate and report on environmental performance to stakeholders.

• To fulfill mandatory statutory reporting.

• To adhere to the principles of continuous improvement.

• To achieve and retain certification in accordance with environmental management standards.

In the introduction, we described some of the most common voluntary and compulsory environmental management schemes, which are again summarized in Figure 2.11. Some of the requirements imposed by these schemes are compulsory, others are voluntary, but at the core of all of them is, once again, the production process where energy is consumed and raw materials processed. The production process is the

place where relevant data is measured, and this measured value will in turn form performance indicators, which will be used to track progress toward given performance targets.

Selected environmental performance objectives will define the indicators that have to be monitored, which will in turn identify the parameters that need to be measured or calculated in addition to those already covered by the measurement of energy performance indicators (see Table 2.1). Table 2.1 refers to our tuna cannery case study. Column 1 contains the resource types that are to be measured, column 2
