Top 100 Key Players companies in Greenhouse effect
by Highest Patent Value in the world in 2020

The Greenhouse effect top 100 is Discovery PatSnap’ annual ranking of the top 100 Highest Patent Value Greenhouse effect Key Players in the world. Discovery has identified the top key players, startups & unicorns, fast-growings, news entrants in 2020, ranking from differnt perspectives, including patent filing intensity, academic research capability, news media heat. The company list is generated from various data types.
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases (i.e., greenhouse gases) in a planet's atmosphere radiate energy in all directions. Part of this radiation is directed towards the surface, warming it. The intensity of the downward radiation – that is, the strength of the greenhouse effect – will depend on the atmosphere's temperature and on the amount of greenhouse gases that the atmosphere contains.
