The Enviro-Mark Programme

The Enviro-Mark Programme mentors organisations to develop, implement and maintain an Environmental Management System (EMS) and verifies their work. An EMS is a planned approach to managing environmental impacts. Organisations identify the significant environmental impacts arising from everything they do and then develop plans to prevent or reduce those impacts. An organisation can achieve one of five Enviro-Mark Certification levels (Bronze, Silver, Gold, Platinum, and Diamond). Each Enviro-Mark level builds on the one before, so higher levels include all the requirements of lower levels. The final level is equivalent to ISO 14001 requirements.


Enviro-Mark Bronze logoEnviro-Mark Bronze Certification

Enviro-Mark Bronze certified organisations have thought about which activities their EMS must control. Their EMS could cover one or all sites or a specific part of their operation. They must explain any reasoning behind excluding areas. They also meet any applicable health, safety and environmental legislation for the areas of their organisation covered by the EMS.

To achieve Enviro-Mark Bronze certification, an organisation:

  • Understands the scope of their EMS (i.e., are there any parts of the organisation that need to be excluded from the EMS and why); 
  • Exhibits no non-compliances with New Zealand’s applicable health and safety and environmental legislation.

Enviro-Mark Silver logoEnviro-Mark Silver Certification

Enviro-Mark Silver certified organisations have identified key environmental issues, including any potential risks or opportunities and understand which of these are significant. They have developed a formal environmental policy covering their position on pollution prevention, risk management, and continual improvement of environmental impacts. They maintain legal compliance.

To achieve Enviro-Mark Silver certification, an organisation:
  • Identifies and evaluates their significant environmental issues arising from activities, products and services;
  • Actively monitors their ongoing compliance with New Zealand legislation and ensures they are aware of any changes to obligations;
  • Produces an environmental policy statement;
  • Understands the scope of their EMS (i.e., are there any parts of the organisation that need to be excluded from the EMS and why);
  • Exhibits no non-compliances with New Zealand’s applicable health and safety and environmental legislation.


Enviro-Mark Gold Certificationgold certified

Enviro-Mark Gold certified organisations have developed and implemented a comprehensive plan to help them achieve their environmental policy goals. They are measuring their significant impacts and are actively managing them. 

To achieve Enviro-Mark Gold certification, an organisation:

The Energy-Mark Programme

The Energy-Mark Programme mentors organisations to develop, implement and maintain an Energy Management System and verifies their work. An energy management system is a planned approach to manage energy use and improve performance and efficiency. An organisation can achieve one of three Energy-Mark Certification levels (Bronze, Silver, and Gold). Each Energy-Mark level builds on the one before, so higher levels include all the requirements of lower levels. The final level is equivalent to ISO 50001 requirements.


Energy-Mark Bronze logoEnergy-Mark Bronze Certification

Energy-Mark Bronze certified organisations have developed an energy policy and demonstrated a commitment to energy management. Through the guidance of Energy-Mark the organisation has reviewed its energy usage, decided on its energy baseline and defined its performance indicators.

To achieve Energy-Mark Bronze certification, an organisation:

  • Defines and documents the scope and boundaries its energy management system;
  • Defines, establishes, implements and maintains an energy policy which illustrates the  organisation's commitment to achieving energy performance improvements;

CEMARS LogoCEMARS Certified organisations

(Certified Emissions Measurement And Reduction Scheme)

This certification is awarded to companies that are actively working to measure and manage their carbon footprint.

To achieve CEMARS certification, an organisation must measure their organisation’s full greenhouse gas (GHG) emissions (also known as a carbon footprint) so they understand what their impact is on the global climate. They measure all operational emissions required under the international standard for carbon footprints, ISO 14064, including vehicles, business travel, fuel and electricity, paper, and waste. The emissions are measured annually and the inventory is independently verified to ensure it is accurate and complete.  Once they have measured their footprint, the organisation must develop plans to manage and reduce their emissions continually. As part of achieving CEMARS certification, the organisation needs to achieve emissions reductions on a five year cycle.


CEMARS LogoCEMARS Certified products and services

(Certified Emissions Measurement And Reduction Scheme)

This certification is awarded to products and services that are actively working to measure and manage their carbon footprint.

To achieve CEMARS certification for a product or service, the provider must measure the full lifecycle greenhouse gas (GHG) emissions (also known as a carbon footprint) so they understand what their impact is on the global climate. They measure all lifecycle emissions required under the international standard for product carbon footprints, PAS 2050, including source raw materials and components, production of the product, distribution and use of the product, and any disposal of waste. The emissions are measured annually and the inventory is independently verified to ensure it is accurate and complete.  Once they have measured their footprint, the organisation must develop plans to manage and reduce the product or service’s emissions continually. As part of achieving CEMARS certification, the product needs to achieve emissions reductions on a five year cycle.

This certification is awarded to companies that are measuring, reducing and offsetting their carbon footprint.

To achieve carboNZero certification, an organisation must measure their organisation’s full greenhouse gas (GHG) emissions (also known as a carbon footprint) so they understand what their impact is on the global climate. They measure all operational emissions required under the international standard for carbon footprints, ISO 14064, including vehicles, business travel, fuel and electricity, paper, and waste. The emissions are measured annually and the inventory is independently verified to ensure it is accurate and complete.  Once they have measured their footprint, the organisation must develop plans to manage and reduce their emissions continually. Each year, the organisation then offsets any remaining emissions through the purchase of verified carbon credits to achieve net zero emissions. As part of achieving carboNZero certification, the organisation needs to achieve emissions reductions on a five year cycle.
