Every Meal Should Require Less Forest.

Lower fuelwood demand reduces pressure on forests while returning time to households and strengthening climate resilience.

This Is What Cooking Fuel Looks Like.

Every piece is gathered, carried, purchased, transported, stored, and burned.

Less Wood Means Less Carrying.

Measured at the Cooking Task.

PWS now reports task-specific fuel savings rather than extrapolating a single household-wide or fleet-wide wood-savings figure.

Forests Protect More Than Trees.

Forests support soil stability, water retention, watersheds, and climate resilience. Less fuel demand gives the landscape more room to recover.

The Difference Is Visible in a Single Pot.

Traditional: ≈2.5 kg wood to boil 5 liters.

La Mazateca Gen 2.x: ≈0.9 kg.

≈64%

less wood for the 5-liter boil task.

Tortilla cooking uses approximately 50% less wood. PWS does not currently publish a single household-wide or fleet-wide wood-savings percentage.

PWS does not publish a numeric CO₂ reduction yet. The public claim remains reduced fuel demand, reduced forest pressure, and contribution to climate resilience.
