Activities which develop (including consultancy and research), produces or implement new or improved processes or products, that contribute to:

• produce renewable energy or sustainable materials
• reduce the use of natural resources by exploiting the resources or energy more efficiently
• reduce the harm caused by fossil fuels
• reduce pollution problems through products, processes and / or consultation

Cleantech represents a diverse range of products, services and processes, all intended to:

• provide superior performance at lower costs, while
• greatly reducing or eliminating negative ecological impact, at the same time as
• improving the productive and responsible use of natural resources

As it encompasses many different types of technologies, cleantech as an investment category has typically  been divided into 11 sectors, for which non-exclusive examples of technologies are provided here:

1. Energy Generation: wind, solar, hydro/marine, geothermal, biofuels
2. Energy Storage: advanced batteries, hybrid systems
3. Energy Infrastructure: management, transmission
4. Energy Efficiency: lighting, buildings, glass, fuel cells
5. Transportation and Logistics: vehicles, logistics, structures, fuels
6. Water and Wastewater: conservation, purification, treatment
7. Air and Environment: emissions monitoring and offset, trading
8. Advanced Materials: nano, bio, green chemicals
9. Manufacturing and Industrial: advanced packaging, smart production
10. Agriculture: natural pesticides, land management, aquaculture
11. Recycling and Waste: recycling, waste treatment and recovery
