As environmental leaders and change makers meet virtually for the Fifth Session of the United Nations Environment Assembly (UNEA) in February 2021, the issue of deforestation has been central to their discussions.
“There can be no conversation on climate change without including forests and deforestation,” said Gabriel Labbate, a forestry expert with the United Nations Programme on Reducing Emissions from Deforestation and Forest Degradation (UN-REDD). “It is fundamental in the fight against the environmental emergency that faces us.”
Forests and woodlands are important stores of planet-warming carbon dioxide, soaking up 30 per cent of emissions from industry and fossil fuels. Their role in capturing and storing carbon is critical to mitigating the risks that climate change poses to the world’s food systems.
But every year, the world loses 7 million hectares of forests, an area the size of Portugal. Globally, primary forest area has fallen by over 80 million hectares since 1990, found the hallmark State of the World’s Forests report, produced by the United Nations Environment Programme (UNEP) and the Food and Agriculture Organisation (FAO). Today, forest fires, pests, diseases, invasive species, drought and extreme weather events put at least another 100 million hectares at risk.
At the UN Environment Assembly, experts discussed the Green Gigaton Challenge, an ambitious public-private partnership backed by the United Nations Environment Programme (UNEP). It aims to catalyse funds for initiatives to combat deforestation, with the target of reducing 1 gigaton (or 1 billion metric tonnes) of emissions by 2025.
The challenge channels public and private sector finance into efforts led by national and subnational governments to halt deforestation, while helping companies support their internal emissions reductions with the purchase of carbon credits. It advocates using nature-based solutions, such as replanting and restoring tropical forests, to reduce emissions. As well as cutting emissions, forests increase biodiversity and regulate water, offering a rounded environmental solution.
“Reducing emissions by 1 gigaton is the same as taking 80 per cent of all cars off the roads in the United States. It has a huge impact and the potential to deliver lasting environmental change. As countries look to rebuild their economies in the wake of COVID-19, 2021 can be the year we make a quantum shift in scale, funding and results,” said Niklas Hagelberg, Coordinator of UNEP’s climate change programme.
At the Green Gigaton Challenge event, participants – who included Ministers of the Environment from various countries – discussed how private sector funding can jump-start forest-based solutions to climate change. Key to this is getting large corporations to understand how reforesting can help them meet their emissions reduction targets in a cost-effective way.
“We see private sector commitment growing and this is crucial in reducing emissions,” said Tim Christophersen, a UNEP ecosystems expert. “2021 provides a unique opportunity to make forests a real pillar of climate mitigation efforts. We will need to send clear and consistent policy signals to ensure this emerging market will be useful and can grow.”
The Green Gigaton Challenge is measurable, and financing can be results-based, meaning funds are released as targets are met. This results in more resources allocated as it gives donors, both private and public, peace of mind that they are getting what they pay for.
Initiatives like this are a step towards reducing global warming. The past decade was the hottest in human history and experts say the planet is on pace for in excess of 3°C of warming, a figure that could have catastrophic consequences.
UNEP is at the forefront of efforts to meet the targets of the Paris Agreement, namely keeping the global temperature rise to well below 2°C, and preferably to 1.5°C, compared to pre-industrial levels.
To this end, UNEP has developed a Six-Sector Solution to cutting emissions. The solution provides a roadmap to how emissions can be reduced across sectors in order to meet the annual 29-32 gigaton reduction needed to limit temperature rise. The six sectors identified are agriculture and food; forests and land use; buildings and cities; transport; energy; and cities.
