Global Net-Zero Reached
Global net CO₂ emissions reach zero — total anthropogenic CO₂ emissions are balanced by removals through natural sinks and engineered carbon capture.

The world achieves a genuine balance between CO₂ emissions and removals. The transition, however uneven across economies, completes. Warming stabilizes.
The 2050 net-zero target proves too ambitious. Emissions trajectories miss the mark — partial progress is made, but net-zero is pushed past 2065 or remains aspirational.
Where things stand
The 2050 net-zero target is a policy commitment — not a trajectory. The IPCC AR6 synthesis finds that policies in place as of the early 2020s would lead to approximately 3.2°C of warming; national pledges under the Paris Agreement bring this to roughly 2.4–2.8°C. Reaching 1.5°C requires net-zero CO₂ by approximately 2050. The gap between pledged and implemented policy is substantial.
Hard-to-abate sectors define the core problem:
- Aviation and shipping account for roughly 5% of global CO₂ and have no near-term decarbonization pathway at commercial scale
- Steel and cement require either green hydrogen or carbon capture and storage — neither competitive as of 2026
- Agriculture and land use, including methane from livestock, represent emissions that carbon removal must compensate for
Carbon removal is the area of greatest uncertainty. Net-zero by 2050 in IPCC scenarios requires billions of tonnes of CO₂ removal per year by mid-century through bioenergy with carbon capture (BECCS) and direct air capture (DAC). As of 2026, global DAC capacity is measured in tens of thousands of tonnes per year — a five-to-six order-of-magnitude scale-up required in under 25 years.
What would move this probability: China’s peak-emissions date is the single largest lever. China accounts for roughly 30% of global emissions; an early peak and aggressive decline would change the trajectory substantially. India’s development path and coal dependency is the second-largest uncertain variable. On the technology side: a step-change reduction in DAC costs (analogous to solar panel cost curves) would shift the feasibility calculation for the final 10–20% of emissions.
The p_ever of 0.60 reflects that the physics and engineering are achievable, but the required political economy — simultaneously, across every major economy — is not historically precedented.
