Monitoring is a periodically gathering and assessment of data that aims at providing detailed and regular information on the progress or delay of an ongoing activity. Monitoring gives an oversight of the implementation stage of the activity. Its purpose is to determine if the outputs, deliveries and schedules planned are on course and in time and if targets can be reached so that action can be taken to correct the deficiencies as quickly as possible.

[National Cleaner Production Centres]

National Cleaner Production Centres (NCPCs), as mentioned in the toolkit, deliver environment-related services to enterprises, government agencies and other organizations, mainly in their respective country. Their key services include: information dissemination and awareness creation; professional training; in plant assessments and demonstrations; policy advice; and support for the transfer of Environmentally Sound Technologies. See also: publication.


It is the introduction of contaminants (unwanted constituents) into the natural environment that causes adverse change. Pollution can be chemical substances as well as noise, heat or light. Pollutants can occur in air, soil and water and can affect human health and the environment. 

[Pollution control]

A term used in environmental management, meaning the control of emissions and effluents into air, water and soil.

[Pollution prevention]

Measures that help to reduce the amount of pollution into the air, water and soil. In contracts to pollution control, pollution prevention seeks to reduce the amount of pollution at its source by increasing the efficiency of a process. 

[Process optimization]

The discipline of adjusting a process to optimize some specified set of parameters. The most common goals are minimizing cost, maximizing output and/or efficiency.

[(Process) parameters

A parameter is one out of a set of measurable factors, such as temperature or pressure that defines a system or process and determines its behaviour. The measurement of process parameters is important in monitoring a process and to keep the process under control. The four commonly measured parameters are temperature, pressure, level and flow.

[Public Private Partnership (PPP)]

PPP is a contractual arrangement between a public agency and a private sector entity. Through this agreement, the skills and assets of each sector (public and private) are shared in delivering a service or facility for the use of the general public.

[Public Procurement]

Public Procurement can be defined as the acquisition, whether under formal contract or not, of works, supplies and services by public bodies. It ranges from the purchase of routine supplies or services to formal tendering and placing contracts for large infrastructural projects. See also [Green Public Procurement].

[Responsible Care]

Global chemical industry’s initiative to improve health, environmental performance, enhance security, and to communicate with stakeholders about products and processes. See also here.

[Resource Efficient and Cleaner Production (RECP)]

RECP is the continuous application of an integrated preventive environmental strategy to processes, products and services to increase efficiency and reduce risks to humans and the environment. It specifically works to advance the three dimensions of sustainable development in an integrated manner, by catalysing: 

  • Production Efficiency through optimization of the productive use of natural resources (materials, energy and water) by enterprises and other organizations;
  • Environmental Protection through minimization of the impact on environment and nature, by preventing the generation of waste and emissions and improving the use of chemicals in enterprises and other organizations; and
  • Social Enhancement through minimization of risks to people and communities from enterprises and other organizations and supporting their own development.


Directive on the Restriction of the use of certain hazardous substances in electrical and electronic equipment, adopted in February 2003 by the European Union (EU) and restricts (with exceptions) the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment.

[Safety Data Sheet (SDS)/Material Safety Data sheet (MSDS)]

A document that provides workers and other personnel (e.g. emergency personnel) with information on the substance like physical data (melting point, boiling point, etc.), toxicity, health effects, storage, reactivity, disposal, etc. for safe handling and working with that substance. The format of a SDS/MSDS may vary, depending also on national requirements.

[Sustainability Criteria for Chemical Leasing]

See here

[Sustainable Chemistry]

The concept of sustainable chemistry exists to link preventative protection of the environment and health with an innovative economic strategy that will also result in more jobs. It is a  broad-ranging area that concerns stakeholders in the scientific community, the economy, public authorities, and environmental and consumer advocate associations. Source: Umweltbundesamt

[Sustainable development]

Sustainable development - development that meets the needs of the present without compromising the ability of future generations to meet their own needs.


A person, group, or organization that has direct or indirect involvement in the actions, objectives and policies of an entity. Key stakeholders in a business organization include creditors, customers, directors, employees, government (and its agencies), owners (shareholders), suppliers, unions, and the community from which the business draws its resources.

[Technical specification]

A detailed description of technical requirements, usually with specific acceptance criteria, stated in terms suitable to form the basis for the actual design development and production processes of an item having the qualities specified in the operational characteristics. 

[Unit of payment]

Charge per unit. In Chemical Leasing, functional units (volume of treated water, area coated, etc.) are used to quantify the payment.

[Variation tolerance]

Variation is the allowable deviation from a standard or any agreed target, it gives the extent to which or the range within a thing varies. The variation tolerance is the extent a customer is willing to accept a variation from the standard or agreed target.

[Volume based payment]

Traditional sales model in which the payment of chemicals is directly linked to the volume of the chemical, for example $/ per ton or € per liter.
