Reduction of energy consumption
Report the amount of reductions in energy consumption achieved as a direct result of conservation and efficiency initiatives, in joules or multiples.
Report the types of energy included in the reductions: fuel, electricity, heating, cooling, and steam.
Report the basis for calculating reductions in energy consumption such as base year or baseline, and the rationale for choosing it.
Report standards, methodologies, and assumptions used.
An organization’s ability to use energy efficiently can be revealed by its reductions in energy consumption. Energy consumption has a direct effect on the environmental footprint of the organization, its operational costs, and exposure to fluctuations in energy supply and prices.
Calculate or estimate the energy saved by initiatives to reduce energy use and increase energy efficiency. Reductions in energy consumption that result from reduced production capacity or outsourcing should not be included in this Indicator.
Initiatives include, as a minimum:
- Process redesign
- Conversion and retrofitting of equipment
- Changes in employee behavior
- Operational changes
Indicate whether energy savings are estimated, modeled, or sourced from direct measurements. If estimation or modeling is used, disclose the methods used.
Organizations may choose to:
- Report reductions in energy consumption by combining energy types
- Report reductions in energy consumption separately for fuel, electricity, heating, cooling, and steam
Organizations may choose to report reductions disaggregated by initiatives or groups of initiatives.
Organizations with many initiatives to reduce energy consumption may prioritize reporting on initiatives that were implemented in the reporting period, and that have the potential to contribute significantly to reducing energy consumption. These initiatives and their related targets may be described in the DMA for the Energy Aspect.
Organizations are expected to report standards, methodologies, and assumptions used to calculate and measure reduction of energy consumption, with a reference to the calculation tools used. Organizations subject to different standards and methodologies should describe the approach to selecting them.
Potential sources of information include internal energy measurements and supplier information (such as energy-related specifications of new machinery, energy saving light bulbs).
