In a move that sparked global controversy, President Donald Trump has again withdrawn the United States from the Paris Agreement on climate change. This decision, announced immediately after his second-term inauguration, has sent shockwaves through international climate circles.
The withdrawal shifts the global balance in climate action as well as raises questions about the second-biggest emitter’s role in addressing one of the most pressing challenges of our time. With fossil fuel policies dominating Trump’s second term, will this setback jeopardize global decarbonization goals?
What is the Paris Agreement and What is America’s History with It?
The Paris Agreement, signed in 2015, is a landmark international pact aimed at limiting global warming to below 2°C, with efforts to keep it to 1.5°C. The agreement is non-binding, meaning nations aren’t legally required to cut their climate emissions. Instead, each country sets its own emissions targets and strategies for achieving them.
The United States played a pivotal role in shaping the Paris Agreement, signing it in 2015 under President Obama. The country pledged to reduce greenhouse gas emissions by 26-28% below 2005 levels by 2025.
To meet these goals, policies like the Clean Power Plan and federal investments in clean energy were introduced. However, in 2017, President Trump announced the country’s withdrawal, citing economic concerns.
Despite rejoining under President Biden in 2021, progress has been inconsistent. Notably, the U.S. committed $3 billion to the Green Climate Fund. But it only delivered $1 billion, leaving a funding gap for developing nations.
U.S. Withdrawal Shakes Global Climate Action: What’s at Stake?
The United States is the second-largest carbon emitter globally, behind China, contributing about 15% of the world’s total GHG emissions. Its participation in the Paris Agreement has always been crucial for global climate efforts.
Trump’s executive order declared the U.S.’s withdrawal effective immediately, bypassing the standard one-year notice period required under the agreement. This swift exit has left many nations scrambling to adjust their strategies, particularly those that depended on U.S. leadership and funding.
Under President Biden, the country committed to reducing its emissions by 50-66% by 2035 and achieving net-zero emissions by 2050. These ambitious goals were a cornerstone of the global push toward sustainable development.
The withdrawal halts progress on these targets and eliminates billions of dollars in climate financing for developing countries. These funds were vital for supporting vulnerable nations in their fight against rising sea levels, extreme weather events, and other climate impacts.
- Notably, U.S. emissions fell only 0.2% last year despite Biden’s $1.6 trillion climate agenda.
Trump’s pro-fossil-fuel stance threatens to reverse these modest gains, raising concerns about long-term environmental and economic impacts.
While the Paris Agreement is nonbinding, its symbolic and practical importance cannot be overstated. It has driven global investments in renewable energy, encouraged technological innovation, and fostered international collaboration. Since its adoption, wind and solar energy have grown exponentially, and clean energy investments have nearly doubled compared to fossil fuels.
However, global emissions remain far from the reductions needed to meet climate targets—the U.S. withdrawal risks undermining this fragile progress at a critical juncture.
Interestingly, multibillionaire Elon Musk, who is a Trump cheerleader once posted on X in 2017 during Trump’s first exit:
“Climate change is real. Leaving Paris is not good for America or the world.”
Trump’s Fossil Fuel Agenda: A Step Forward to “Energy Dominance”, But a Step Backward for Climate Goals
Central to Trump’s decision is his administration’s prioritization of fossil fuels. During his second inaugural address, he declared a “national energy emergency” and emphasized the need to increase oil and gas production.
“We will drill, baby, drill,” he proclaimed, signaling a sharp pivot from the clean energy policies of the previous administration.
Trump’s energy policies aim to dismantle regulations that limit fossil fuel development and expand domestic production. This approach includes reopening federal lands for drilling, rolling back environmental protections, and halting incentives for renewable energy.
Critics argue that these policies reflect a short-term focus on economic growth at the expense of long-term environmental sustainability.
Remarkably, an analysis suggests that U.S. greenhouse gas emissions would be 28% below 2005 levels by 2030 if Trump wins a second term and rolls back Biden’s policies, falling short of the 50-52% target.
Under a Biden reelection, emissions would drop to around 43% below 2005 levels. Biden’s policies like the Inflation Reduction Act provided tax incentives for renewable energy projects and set ambitious standards for vehicle emissions and energy efficiency. Trump’s rollback of these policies could slow the adoption of green technologies and jeopardize the U.S.’s position as a leader in clean energy innovation.
In Trump’s scenario, U.S. emissions in 2030 would be about 1GtCO2e higher than under Biden, adding around 4GtCO2e cumulatively by 2030. These extra emissions would result in global climate damages exceeding $900 billion using the EPA’s carbon cost of $230 per tonne.
Resistance at Home
Coalitions of U.S. states, cities, and businesses are stepping up, vowing to meet climate targets despite federal inaction. The U.S. Climate Alliance, representing 24 states, pledges to cut emissions by 66% by 2035.
The America Is All In coalition, co-chaired by former Biden administration officials, represents states that account for nearly 60% of the U.S. economy. Gina McCarthy, the coalition’s co-chair highlighted these subnational actors’ vow to uphold the Paris Agreement’s targets, saying:
“By leaving the Paris Agreement, this administration has abdicated its responsibility to protect the American people and our national security…But rest assured, our states, cities, businesses, and local institutions stand ready to pick up the baton of U.S. climate leadership and do all they can — despite federal complacency — to continue the shift to a clean energy economy.”
Global Repercussions: A Ripple Effect on Climate Action
The international response to Trump’s withdrawal has been overwhelmingly negative. Climate advocates, scientists, and world leaders have condemned the decision, calling it an abdication of responsibility.
This is particularly concerning ahead of the COP30 climate talks in Brazil, where nations are expected to review and strengthen their commitments under the Paris Agreement.
Globally, Trump’s decision could embolden other nations to scale back their climate ambitions. Countries heavily dependent on fossil fuels may see the U.S. withdrawal as a justification for delaying their transitions to renewable energy. Additionally, the absence of U.S. leadership could undermine trust and cooperation in international climate negotiations, making it more difficult to achieve collective action.
As the world faces unprecedented climate challenges, the need for decisive action has never been greater. Trump’s withdrawal highlights the fragile balance between economic interests and environmental responsibility. While some estimates and projections exist, the real effects of Trump’s fossil fuel agenda remain to be seen and the world is on watch.
