1. The manufacturing of green products, such as those used in renewable energy systems and clean technology equipment of all kinds, and

2. The greening of production, meaning by reducing pollution or waste by minimizing natural resources use and reducing emission. 

The most thing that is going on, and is a great potential industry is the greening of production, which will be an advantage in the future regulations and classification of industry.

World's largest manufacturing economy are:

1. United States, producing 21% of global manufactured products.

2. China, 15%

3. Japan, 12 %

This is actually a chance for them or competing country to turn their industry to be more "green" and "zero carbon" as there would be a rapid growing renewable energy and clean tech sectors opportunities.

International organization such as the United Nations, and World Bank, are joined by a host of public, non-profit, and private sector organizations, such as the Carbon War Room and Carbon Disclosure Project in making notable progress when it comes to driving forward green manufacturing, green business methods and green practices.

Prominent environmental organizations and businesses are even bridging the divide that separate them, joining the efforts to conserve natural resources, natural habits, and biodiversity.
