Build a Carbon Footprint Calculator with AI

Estimate your annual CO2 emissions from transportation, home energy, diet, and consumer habits. Compare your footprint to national averages, get personalized reduction tips, and calculate the cost to offset your emissions through verified carbon credit programs.

Build Prompt

Copy this prompt into Claude Code

Build a static HTML carbon footprint calculator. Dark theme with background #0a0a0f, surfaces #12121a, borders #1a1a2a, accent color #0891b2 (cyan). Data from inline `const EMISSION_FACTORS = [...]`, `const AVERAGES = [...]`, `const TIPS = [...]`. Categories: (1) Transportation — car type (gas/hybrid/EV), annual miles, flights (short/medium/long haul, frequency), public transit usage. (2) Home Energy — electricity kWh/month, natural gas therms/month, heating fuel, renewable energy %. (3) Diet — meat frequency (daily/few times/weekly/rarely/never), dairy, local/imported food ratio. (4) Shopping — clothing purchases/year, electronics, general consumption level (minimal/moderate/high). Emission factors: CO2e per mile by vehicle type, per flight by distance, per kWh by grid region, per food type, per consumer good category. Layout: Header with title. Step-by-step wizard: one category per step with sliders and selectors. Results dashboard: total annual CO2 (metric tons), comparison to US average (16 tons), global average (4 tons), and Paris Agreement target (2 tons). Category breakdown donut chart. Reduction tips: personalized based on highest emission categories with estimated CO2 savings per tip. Offset calculator: tons to offset × cost per ton. Include "What is a Carbon Footprint" guide, "Top 10 Ways to Reduce Emissions" list, and country comparison table. Save results to localStorage. SEO: title, meta description, OG tags.
