José Scheinkman, an esteemed economist from Columbia University, discusses the economic consequences of deforestation and the urgent need for reforestation policies. He explores the alarming rates of deforestation in the Amazon and its impact on biodiversity, driven by unsustainable practices. Scheinkman emphasizes the importance of carbon credits in making reforestation economically viable and highlights the necessity for sustainable agriculture to aid conservation efforts. The conversation also touches on the ecological importance of preserving the Amazon and the challenges of applying economic insights globally.
The economic valuation of the Amazon's carbon storage is significantly lower in Brazil compared to international markets, complicating conservation efforts.
For reforestation to be economically viable, a carbon price of around $25 per ton is essential to combat deforestation trends.

The Role of Tropical Rainforests in Climate Regulation
Tropical rainforests, characterized by their dense canopies and high biodiversity, play a pivotal role in regulating the global climate. These forests, particularly the Amazon, are critical for carbon capture, effectively storing as much carbon as all U.S. emissions historically. The removal of these trees leads to significant increases in atmospheric CO2, highlighting the urgency of protecting these ecosystems. With the Amazon accounting for approximately 10% of global biodiversity, the implications of deforestation extend beyond carbon regulation to encompass the potential loss of numerous species.
Challenges of Deforestation and Economic Incentives
Deforestation in the Brazilian Amazon has been historically driven by low productivity cattle farming, often taking place on public lands. The military government's policies incentivized land clearing under the guise of economic activity, severely compromising the region's ecological balance. Surprisingly, the estimated value Brazilians place on the Amazon’s carbon is only about $7 per ton, starkly lower than the European trading price of $100 per ton. This disparity illustrates a significant undervaluation of forest ecosystems in Brazil, complicating efforts to curb deforestation.
The Path Toward Sustainable Reforestation Policies
For reforestation to become economically viable, estimates suggest a necessary carbon price of around $25 per ton to counter current deforestation trends. Such a price could facilitate capturing approximately 15 gigatons of carbon over the next 30 years, marking a critical contribution to global emission reduction goals. Additionally, implementing effective policies would require recognizing the full economic benefits of the Amazon while ensuring financial support for local communities impacted by these changes. By integrating both the preservation of forest ecosystems and the economic upliftment of the Amazon region, a sustainable path forward can be established.
Recorded at the Climate Change and the Environment Conference, organised by the AXA Research Fund and CEPR. We are familiar with frightening images of deforestation, and you’ve heard the warnings of the impact on nature if we do not do a better job of protecting our tropical rainforests. But how can we quantify the gains from reversing deforestation, and at what carbon price is reforestation economically rational? José Scheinkman talks to Tim Phillips about the consequences of deforestation, how to create policy levers to reverse the trend, and the benefits if we use carbon credits as a means of restoring nature.
