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.
