English – The Conversation | Planting trees to remove carbon can harm the environment – or protect it: study highlights trade-offs by Ruben Prütz, Postdoctoral Researcher, Potsdam Institute for Climate Impact Research
Forest, Uganda. Julie Ricard, Unsplash, CC BYGlobal efforts to limit climate change require deep cuts to carbon emissions. However, global emissions are still growing. Currently, we emit roughly 42 billion tonnes of carbon dioxide from fossil fuel use and land use changes every year.
To achieve the targets of the Paris Agreement, which included a long-term commitment to limit global warming to 1.5°C, it will also be necessary to do more than cut emissions. What is also needed is large-scale removal of carbon dioxide from the atmosphere. Any delay in emission reductions increases our reliance on future carbon removal. Yet, carbon removal does not come without trade-offs.
Some strategies to remove carbon are very land intensive. Examples include planting trees, or growing crops that can be used as alternative sources for energy production. This would have to be done at massive scale – across millions of square kilometres of land. In turn, this could have serious biodiversity implications if not carefully managed.
