Widespread improvements in the quality of life of many of the world’s populations have gone hand-in-hand with increased demands on natural resources. Increases in the average global temperature, and the frequency of extreme weather events are transforming ecosystems around the world and threatening entire species of plants and animals. Forests are drying up because there is less rainfall and thus more fires, and the glaciers of both the North and South Poles are shrinking. The consequences of global warming affect all of us, but to react and adapt to these challenges, We must work to reduce greenhouse gas emissions and create carbon neutrality.

The largest emitter of greenhouse gas is the energy sector. Other significant sources of greenhouse gases include transportation, industry (especially construction and mining), and agriculture.

Different human activities produce different greenhouse gases. For instance, agriculture produces methane most notably, while the burning of fossil fuels releases carbon dioxide especially.
