The US could still get to net zero
The United States has the potential to slash nearly 90% of its greenhouse gas emissions by 2050, achieving significant strides toward combating climate change without relying on miraculous breakthroughs.
Amidst the discussions at COP28, global leaders are honing in on meeting the Paris Agreement’s ambitious goal of curbing warming to 1.5°C. The challenge’s magnitude is staggering, even for a nation as economically robust and innovative as the U.S.
Recent bipartisan legislation, including the infrastructure law and the Inflation Reduction Act, marks the largest federal investment in clean energy, decarbonization, and climate mitigation in American history. However, studies indicate that these laws alone won’t fully propel the U.S. toward its 2050 net-zero economy objective.
Surprisingly, current solutions offer a promising route to achieve this monumental goal. Three existing strategies—transportation electrification, building decarbonization, and the adoption of clean energy—stand out as game-changers.
Transportation electrification presents a pivotal opportunity. Scaling up electric vehicle (EV) adoption from approximately two million to 240 million by 2050 could significantly steer the U.S. toward net zero. Achieving this demands substantial expansion in battery manufacturing, sourcing minerals globally, and driving consumer EV adoption to sustain this decarbonization avenue.
Moreover, establishing an extensive network of public EV charging stations and enhancing the electric grid’s capacity are essential for enabling widespread transportation electrification.

The decarbonization of buildings, which constitute around 110 million structures in the U.S., holds immense potential. Upgrading these structures—via energy efficiency measures and electrification—requires over a billion interventions. From simple lighting enhancements to substantial transitions from natural gas to electricity, the scale of this endeavor necessitates both low-cost and substantial upgrades.
Simultaneously, electrifying transportation and buildings becomes more impactful when coupled with clean energy sources like solar and wind power. To optimize this, the U.S. must exponentially increase renewable energy generation to constitute 85% of total electricity by 2050, alongside reducing reliance on unabated fossil fuel sources.
This transition entails not only harnessing solar and wind but also enhancing storage capabilities through technologies like batteries. A clean energy grid serves as the linchpin for broader decarbonization efforts across various sectors.
While this roadmap to a net-zero economy is viable, it’s not without challenges, costs, and trade-offs. Achieving such drastic emission reductions demands a collaborative effort involving the federal government, utilities, local governments, NGOs, businesses, and the public.
The journey to a net-zero economy will necessitate addressing multifaceted challenges while maintaining energy reliability, enhancing resilience, securing financing, and ensuring equity. Approaching this complexity with clear-eyed realism is crucial as nations navigate this intricate path toward mitigating the severe impacts of climate change.
