AMR - Automated Meter Reading - generally received from data logger or smart meter. Wikipedia - Automaated Meter Reading - AMR

AM&T - Automated Monitoring and Targeting.

MM&T - Metering, Monitoring and Targeting.

Carbon Dioxide Emissions - The release of carbon dioxide gas (CO2) into the atmosphere. Usually measured in metric tons.

Carbon Emissions - The release of Carbon (C) into the atmosphere. Usually measured in metric tons.

Carbon Footprint - The total carbon emissions for a given person, organization, building, operation etc. The carbon footprint of an operational office typically include the carbon emitted by the commuting of the office staff. Wikipedia - Carbon footprint

Carbon Neutral - A person, building, organisation or operation that emits the same amount of carbon as it absorbs. Typically carbon emissions are offset by the planting of trees (which absorb carbon dioxide when they photosynthesize) enabling an orgainsation to become 'Carbon Neutral'.

Carbon Offset - The process of voluntarily offsetting carbon emissions by, for example, planting trees, investing in renewable energy. Wikipedia - Carbon Offset

CRC - Carbon Reduction Commitment is the government's legally binding climate change and energy saving scheme. This is a mandatory scheme to promote energy efficiency and help reduce carbon emissions. Best practice in the scheme will be to devise a carbon abatement strategy and consider energy efficiency measures. The first compliance year is next year!

Carbon Trading - The process of buying and selling carbon credits. Large companies or organisations are assigned a quota of carbon that they are allowed to emit. If a company's emissions are less than its quota then it can sell credits if emissions are more then it will need to buy carbon credits.

Climate Change - Generally refers to the change of the climate by man's emission of Greenhouse gasses.

Carbonplus+ - This is a term devised by the Woodland Trust to describe a business or organisation that absorbs more carbon than it emits.

Data analysis
Data analysis techniques which lead to savings identification include correlation with production volumes, degree days, analysis of peak and base loads and benchmarking.

Data Logger - A device used to record and store data - in the world of energy management data loggers generally count pulses emitted by utility meters. A utility meter with a data logger performs in the same way as a smart meter. Usually data loggers are used with gas and water while smart meters are used with electricty.

DC - Data Collector - Ofgem approved Data Collectors are a necessary part of the electricity billing process. Originally stemming from reading the meter with a 'man in a van' they now receive and validate electricity readings from smart meters before sending it on to the supplier.

DR - Data Retriever - Ofgem approved Data Retrievers are officially allowed to collect data from utility meters for billing purposes. Typically they are also DCs or send the data to a DC before it goes on tot the supplier.

Electricity – half-hourly metering
Sites with a peak load above 100kW have half hourly primary meters providing good quality data for energy management. These sites can access their data via their energy supplier or data collector.

Electricity - non-half-hourly metering
Smaller sites with a peak load below 100kW have non-half hourly primary meters which can only be read manually. These sites will frequently have estimated bills and may need to upgrade to smart metering or half hourly metering to get good quality data.

Gas metering
Most gas sites have manually read meters which provide limited data for energy management. Upgrade to smart metering can be desirable to get good quality data.

Gas and electricity: smart metering
Smart meters are an emerging technology which can produce automatic, regular, meter data for small electricity and gas sites.

M&T - Monitoring and Targeting. 'Monitoring' consumption to 'Target' high consumption. Prior to smart metering this was typically done by analysing consumption data from utility bills. Smart metering gave rise to 'Automated Monitoring and Targeting' with the software systems automatically monitoring and identifying high consumption sites. Wikipedia - Energy Monitoring and Targeting

Pulse Output - A water or gas meter typically needs to have a pulse output to enable it to be logged. Each pulse represents a volume and therefore from these pulses the readings are established.

RM&T - Remote Monitoring and Targeting

Smart meter - In its simplest form a smart meter is a utility meter capable of storing data rather than displaying just the current reading. A fully featured smart meter usually has the option of storing around 1 month of half hourly readings with the ability to send this data across a communication network - often SMS. A smart meter performs in the same way as a meter with a data logger. Smart meters are usually used for electricity. Read an overview of Astralweb's smart metering solution.

Sub-metering
Large sites use sub-metering to understand and closely manage their energy consumption throughout their facilities.
