Amount of money that would be saved if the energy efficiency of commercial and industrial buildings improved by 10 percent: $20 billion.

Amount of greenhouse gas emissions that would be reduced if the energy efficiency of commercial and industrial buildings improved by 10 percent: equal to about 30 million vehicles.
Amount of global carbon dioxide (CO2) released into the atmosphere in 2005: 6,000 million metric tons.
The United Nations World Commission on Environment and Development defines sustainability as "ensuring that we meet our needs without compromising the ability of future generations to meet their own needs."
For NSU, sustainability represents the use of technology in ways that make business sense, while at the same time addressing environmental needs. In other words, use technologies that are cost effective and do not cause irreversible damage to the local, regional and global ecosystems.
By technology we mean how we do things, so this encompasses all of the economic processes and how we live. For example, how we manufacture and distribute goods and services, how we build homes and buildings, how we provide the fuels and energy for the industrial, commercial and residential sectors.
Conservation provides an environmentally and economically sustainable framework for development.
