This document discusses carbon financing and markets. It describes how carbon markets operate on the business and energy sides, but the business side has failed due to lack of green cover, rainfall, carbon biomass production, and water as well as poor farmer lifestyles. The energy side involves energy efficiency, zero carbon energy, and carbon sequestration. Carbon trading allows for limiting greenhouse gases by creating a market for emissions permits and offsets. The largest carbon markets are in the US, UK, Australia, Brazil, Japan, and Canada. International associations aim to increase comparability, reduce emissions leakage, and ensure carbon market sustainability as the Kyoto model is no longer valid.
