Carbon dioxide (CO2) is the primary greenhouse gas emitted by human activities, primarily through the burning of fossil fuels for energy production, transportation, and industrial processes.

Trees absorb carbon dioxide during photosynthesis and release oxygen. When trees are cut down or burned, the carbon stored in their trunks and leaves is released back into the atmosphere as carbon dioxide, contributing to the increase in carbon footprint.

Agriculture, particularly the clearing of forests for farming and grazing land, is a major contributor to deforestation. The demand for agricultural products, such as palm oil, soybeans, and beef, drives the conversion of forests into agricultural land.

Afforestation refers to the planting of trees in areas that were not previously forested. It is one of the strategies used to offset carbon emissions by increasing the amount of carbon dioxide absorbed from the atmosphere.

Brazil has the highest rate of deforestation in the world, primarily due to the expansion of agriculture, particularly cattle ranching and soybean farming.

Decarbonization refers to the process of reducing greenhouse gas emissions, particularly carbon dioxide, from various sources, such as energy production, transportation, and industry.

Planting trees is an example of a carbon offset project because trees absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce greenhouse gas emissions.

Carbon footprint refers to the total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2).

The energy sector, particularly the burning of fossil fuels for electricity generation and transportation, is the largest contributor to global carbon emissions.

Carbon Capture and Storage (CCS) refers to the process of capturing carbon dioxide from industrial sources and storing it underground or in geological formations to prevent its release into the atmosphere.

Selective logging is an example of a sustainable forestry practice because it involves the selective harvesting of trees while maintaining the overall health and biodiversity of the forest.

Demand-Side Management refers to the process of reducing the demand for products and services that contribute to carbon emissions, typically through energy efficiency measures, behavioral changes, and promoting sustainable consumption patterns.

A carbon tax is an example of a policy instrument used to reduce carbon emissions by imposing a tax on the carbon content of fossil fuels or the emissions they produce.

Decarbonization refers to the process of transitioning to a low-carbon economy by reducing greenhouse gas emissions, particularly carbon dioxide, from various sources, such as energy production, transportation, and industry.

Solar energy is an example of a renewable energy source because it is derived from the sun's energy, which is a continuous and sustainable source of power.
