​​​The Green Economy programme focuses on the reference measurements required in support of reference material production and environmental, industrial, and applied monitoring as well as the development of alternative technologies to support the production of reference materials, certified reference materials, quality control standards and the maintenance of reference measurements and Proficiency Testing Schemes (PTS) offered to industry. NMISA continues to develop and improve Primary Reference Gas Mixtures (PRGMs) for air pollution monitoring. NMISA collaborates with universities, research institutions and industry, and offers advanced materials measurement services to diverse industries such as additive manufacturing, metals/alloy beneficiation and processing, packaging, electronics, and advanced material research. Some of the key projects include the design and fabrication of cost effective solar cell devices. These devices will prove to be beneficial to the country, as it will be used in rural areas to generate electricity, using only the sun’s energy to power the device. ​
