What, exactly, is the relationship between deforestation and climate change? The Rainforest Alliance breaks down the numbers for you—and explains our innovative approach to keeping forests standing.

Climate change is a systemic risk that poses vulnerabilities to businesses in all sectors, and has the potential to trigger the collapse of an entire industry or economy. As the material risks posed by climate change become increasingly apparent, an growing number of investors are mobilizing to address this risk in their portfolios.

Published Jul 27, Updated Dec 9, Tropical forest trees, like all green plants, take in carbon dioxide and release oxygen during photosynthesis. Plants also carry out the opposite process—known as respiration—in which they emit carbon dioxide, but generally in smaller amounts than they take in during photosynthesis. The surplus carbon is stored in the plant, helping it to grow. When trees are cut down and burned or allowed to rot, their stored carbon is released into the air as carbon dioxide.

And this is how deforestation and forest degradation contribute to global warming. According to the best current estimate, deforestation is responsible for about 10 percent of all global warming emissions. Where did that 10 percent figure come from?

Why does deforestation occur? Forests are cleared to make way for any of a long list of agricultural products and other human activities. But UCS analysis shows that a majority of tropical deforestation occurring today can be traced to just four globally traded commodities : beef , soybeans , palm oil , and wood products. We need to protect tropical forests from deforestation and degradation if we want to reduce emissions to the levels needed to protect the planet against the worst global warming impacts.

Ending deforestation will not solve global warming by itself, of course—urgent action is needed to cut the other 90 percent of emissions. But the problem cannot be solved if the role of tropical deforestation is ignored. And reducing deforestation has other benefits beyond reducing global warming pollution.

Tropical forests are home to many unique species of animals and plants. Animals such as the jaguar risk extinction if we do not act to protect their tropical forest habitat. In addition, tropical forests are crucial sources of food, medicine, and clean drinking water for people in developing countries. Tropical forests help regulate regional rainfall and prevent both floods and droughts. Reducing deforestation is not only a beneficial action against global warming—it also can make important contributions to saving biodiversity and supporting sustainable development.

The good news is that tropical deforestation can be reduced—and, in many places, already is being reduced. Continuing progress will require a sustained commitment by governments, businesses, consumers, and non-governmental organizations to the goal of ending—and, where possible, reversing—tropical deforestation.

Deforestation and Greenhouse-Gas Emissions

Deforestation is a primary contributor to climate change. Global models and national greenhouse gas inventories give similar results for deforestation emissions. Growing forests are a carbon sink with additional potential to mitigate the effects of climate change. Some of the effects of climate change , such as more wildfires , may increase deforestation. The vast majority of agricultural activity resulting in deforestation is subsidized by government tax revenue.


Deforestation and Climate Change. Introduction. Deforestation has been an issue for decades, leading to massive loss of species and biodiversity.

Forests are a stabilising force for the climate. They regulate ecosystems, protect biodiversity, play an integral part in the carbon cycle, support livelihoods, and supply goods and services that can drive sustainable growth. They act as both a cause and a solution for greenhouse gas emissions. About half of these GtCO 2 e annually comes from deforestation and forest degradation.

Explore the relationship between forests and several key themes critical to sustainability and the health of our future ecosystems. Forests remove and store carbon from the atmosphere, representing a cost-effective solution for mitigating climate change. The loss or degradation of forests compromises their ability to remove emissions. Forests provide a natural solution for removing carbon from the atmosphere. Forests absorb and store carbon emissions caused by human activity, like burning fossil fuels, which include coal, natural gas and oil. Forests' ability to absorb carbon from the atmosphere can be compromised by conversion into agricultural lands, commodity production, urbanization, disease and fires that cause forest loss.

We apologize for the inconvenience...

Loss of forests contributes as much as 30 percent of global greenhouse-gas emissions each year--rivaling emissions from the global transportation sector. Despite hopes from climate advocates that deforestation policy would be one of the few concrete things coming out of the December UN climate meeting, Copenhagen talks concluded without an agreement for a comprehensive plan for deforestation. Instead, deforestation was put on hold along with discussions for an overall climate agreement. While there is significant consensus on how deforestation programs could be implemented, a number of issues remain under debate.

Large-scale conversion of tropical forests into pastures or annual crops will likely lead to changes in the local microclimate of those regions. Larger diurnal fluctuations of surface temperature and humidity deficit, increased surface runoff during rainy periods and decreased runoff during the dry season, and decreased soil moistrue are to be expected. It is likely that evapotranspiration will be reduced because of less available radiative energy at the canopy level since grass presents a higher albedo than forests, also because of the reduced availability of soil moisture at the rooting zone primarily during the dry season.
