Carbon (or climate) neutral

When activities that reduce or capture carbon are paired successfully with those that produce it, they are said to be carbon neutral or climate neutral.

Carbon footprint

The total amount of greenhouse gases emitted directly and indirectly to support human activities, usually expressed in equivalent tons of either carbon or carbon dioxide.

Carbon trading

Any trading system designed to offset carbon emissions from one activity (such as burning fossil fuels in manufacturing, driving, or flying) with another (such as installing more efficient technologies, planting carbon-reducing plants, or establishing contracts with others not to partake in carbon-releasing activities).

Cerrados

The ecologically rich area in central Brazil (and some of northeastern Paraguay and eastern Bolivia) is a vast savanna - the richest savanna in the world, biologically. It boasts more than 10,400 plant species and 1,300 fauna species, many endemic to the region. Major efforts are underway to preserve this biologically rich savanna.

Climate change

Any long-term significant change in the "average weather" that a given region experiences. Average weather may include average temperature, precipitation and wind patterns. It involves changes in the variability or average state of the atmosphere over durations ranging from decades to millions of years.

CSR (Corporate Social Responsibility)
