Global forest loss hits record — with CO2 in tow

Global forest loss reached a record high in 2024, with tropical regions losing 6.7 million hectares of primary rainforest, an area approximately the size of Panama. Total global tree cover loss reached 30 million hectares, driven by extreme fire seasons, particularly in Canada and Russia. Fires, a mix of human and climate influences, accounted for nearly 50% of primary tropical forest loss, resulting in 4.1 billion tons of CO2 emissions, equivalent to over four times the emissions from air travel in 2023, raising concerns about lessened CO2 absorption and biodiversity.

Analysis

Global forest loss reached an unprecedented high in 2024, with tropical regions experiencing a loss of 6.7 million hectares of primary rainforest, an area comparable to Panama, while total global tree cover loss amounted to 30 million hectares. This surge was significantly driven by extreme fire seasons, notably in non-tropical regions like Canada and Russia. Critically, fires accounted for nearly 50% of primary tropical forest loss in 2024, marking the first time this has been the leading cause in over two decades of tracking data from the University of Maryland and World Resources Institute. These blazes are attributed to a combination of human influences, such as land clearing for agriculture, and climatic factors, including 2024 being the hottest year on record and El Niño, which intensified fires and made them harder to control. The environmental repercussions are substantial, with these global fires generating 4.1 billion tons of CO2 emissions in 2024, a figure equivalent to more than four times the emissions from global air travel in 2023. This development not only exacerbates climate change through direct emissions but also significantly diminishes the planet's CO2 absorption capacity and threatens biodiversity, prompting experts to characterize the situation as a "global red alert" due to the critical role of these forests, particularly in the tropics, for carbon storage and regulating regional climates.

Key Decisions for Investors

• Investors should intensify due diligence on portfolio companies with supply chain exposure to deforestation-linked commodities, particularly in agriculture and raw materials, given rising regulatory scrutiny and reputational risks highlighted by these findings.
• Anticipate increased volatility in agricultural and timber commodity markets due to escalating climate-driven events such as these widespread fires, and assess potential opportunities in sectors focused on carbon capture, reforestation initiatives, and sustainable land management solutions.
• Monitor for an acceleration in global and national policies aimed at curbing deforestation and promoting sustainable land use, as these could present material risks for industries with significant land-use impact and create tailwinds for businesses offering climate mitigation technologies or certified sustainable products.
• Re-evaluate overall portfolio exposure to systemic climate risks, as the reported scale of CO2 emissions and loss of natural carbon sinks underscores the growing financial materiality of environmental degradation and its potential impact on long-term asset viability and market stability.
