Greenhouse gases leaving the air as fast as we add them, so global temperatures stop rising.

The goal in brief

GoalGreenhouse gases leaving the air as fast as we add them, so global temperatures stop rising.

of warming above pre-industrial in 20251
1.44°C
carbon dioxide in the air in 2024, a record2
423.9 ppm
emissions cut by 2035 under current plans3
−12%

Why it matters

Earth was 1.44°C warmer in 2025 than in 1850 to 1900,1 and carbon dioxide in the air reached a record 423.9 ppm in 2024.2 Countries’ current plans would cut emissions only about 12% by 2035, far short of the 55% cut needed to hold warming to 1.5°C.3

How we’ll know it’s done

Finish line
Net-zero emissions by 2050, the pace needed to hold warming to 1.5°C as the Paris Agreement calls for.3
What counts
Net emissions: what we release, minus what forests, soils and proven technology durably take back out.
How it’s checked
Countries’ emissions reports under the UN climate treaty, checked against measured CO₂ in the air and global temperature records.
Our part
We’ll fund this once our vetting team vets an organization working on it.

What follows

  • Heat waves, floods and droughts stop getting worse.H-14Establish a global resilience fund for disaster relief and prevention
  • Oceans absorb less new carbon dioxide, slowing acidification.O-07Rebalance ocean pH to 8.2 (eliminate ocean acidification)
  • Farmers spared ever-rising heat and drought.H-01Eliminate global hunger and malnutrition
  • Coral reefs spared further warming, giving them a chance to recover.O-06Protect and regenerate key ocean ecosystems

How it can be solved

The approaches to this goal, and how many of the organizations taking each one we’ve vetted.

  • Direct air capture

    Machines that pull carbon dioxide straight out of the air.

    3 organizations

  • Biochar

    Turning plant waste into charcoal that locks its carbon away for centuries.

    2 organizations

  • Ocean and mineral removal

    Using minerals and the sea to soak up carbon dioxide.

    1 organization

  • Capture at the source

    Catching carbon dioxide from engines before it escapes.

    1 organization

  • Low-carbon materials

    Building materials that store carbon or skip the emissions of cement.

    2 organizations

  • Carbon markets and certification

    Certifying, trading and advising on carbon credits so removal gets paid for.

    3 organizations

Who’s working on it

We only call a solution proven, measurable and scalable once our vetting team has vetted it. Everything else here, the team is tracking.

Vetted0 organizationsReviewed by our vetting team, and passed all three tests.

  • Proven

    It has worked, with results to show.

  • Measurable

    Its impact can be counted.

  • Scalable

    It can grow toward the size of the goal.

None on this goal yet. When our vetting team vets an organization working on it, it appears here with its vetting report.

Not vetted12 organizationsTracked by our vetting team. Not vetted yet, so we make no claims about them.

Listing an organization isn’t an endorsement. Not vetted means just that: our vetting team is tracking it, and we make no claims about it yet. Last reviewed October 2026.
