What We Mean by 'Measurable Impact'

Beyond Feel-Good Metrics

Many sustainability apps tell you you're "making a difference" without showing how. PfPE is different. We calculate real environmental impact for every quest completed.

What We Measure

CO₂ Emissions Saved

Every transport, energy, and food quest calculates estimated CO₂ reductions based on established research:

• Cycling instead of driving: ~0.21 kg CO₂ per km
• Meatless meal: ~2.5 kg CO₂ per meal
• LED bulb switch: ~40 kg CO₂ per year

Waste Diverted

Recycling and waste reduction quests track:

• Weight of waste diverted from landfill
• Types of materials recycled
• Food waste prevented

Energy Reduced

Energy-focused quests measure:

• Estimated kWh saved
• Equivalent CO₂ reduction
• Cost savings (where applicable)

Nature & Biodiversity

Nature quests track:

• Trees planted
• Green spaces maintained
• Wildlife habitats supported

How We Calculate

Our impact calculations are based on:

• Published research from DEFRA, IPCC, and academic sources
• Conservative estimates — we'd rather undercount than overstate
• Transparent methodology — we publish our calculation methods
• Regular updates — we refine calculations as better data becomes available

Why It Matters

Measurable impact serves everyone:

• Individuals see their real contribution
• Schools can report on programme outcomes
• Councils get data for sustainability targets
• Partners can verify the ROI of their campaigns

Impact you can see. Progress you can prove.
