The prior forest destruction might have happened through deforestation, clearcutting or wildfires. Three important purposes of reforestation programs are for harvesting of wood, for climate change mitigation, and for ecosystem and habitat restoration purposes. On

Geoengineering (also known as climate engineering or climate intervention) is the deliberate large-scale interventions in the Earth’s climate system intended to counteract human-caused climate change. The term commonly encompasses two broad categories: large-scale carbon dioxide removal (CDR) and solar radiation modification (SRM). CDR involves techniques to remove carbon dioxide from the atmosphere and is generally considered a form of climate change mitigation. SRM aims to reduce global warming by reflecting a small portion of sunlight (solar radiation) away from Earth and back into space. A

The RETScreen Clean Energy Management Software (usually shortened to RETScreen Expert) is a software package developed by the Government of Canada. RETScreen Expert was highlighted at the 2016 Clean Energy Ministerial held in San Francisco. The Government of Canada's Treasury Board Secretariat uses RETScreen Expert as its greenhouse gas reporting tool for all federal departments and agencies required to report emissions.

Carbfix is an Icelandic company founded in 2007. It has developed an approach to permanently store CO2 by dissolving it in water and injecting it into basaltic rocks. Once in the subsurface, the injected CO2 reacts with the host rock forming stable carbonate minerals, thus providing permanent storage of the injected CO2

includes a range of activities relating to climate change, and to influencing political decisions on climate change-related regulation, such as the Kyoto Protocol.

REDD+ is a voluntary climate change mitigation framework developed under the United Nations Framework Convention on Climate Change (UNFCCC). It aims to encourage developing countries to reduce greenhouse gas emissions from deforestation and forest degradation, and to promote conservation, sustainable forest management, and enhancement of forest carbon stocks through financial incentives and policy support. The acronym is commonly expanded as "reducing emissions from deforestation and forest degradation in developing countries", and the "+" denotes the additional forest conservation and enhance

British campaign about climate change

Mootral is a British-Swiss company that is developing a food supplement to reduce methane emissions from ruminant animals, chiefly cows and sheep, but also goats. Methane is a major target greenhouse gas and in the 4th protocol report of the Intergovernmental Panel on Climate Change (IPCC) is recommended to increase from a x23 to x72 multiplier because of the magnitude of its effect relative to carbon dioxide and short longevity in Earth's atmosphere.
