Climate ToolsetClimate & Sustainability
Tools for tracking carbon footprint, energy usage, and environmental impact.
Appliance Efficiency Label Reader
Checks an appliance energy label photo's file type and size in your browser. It does not read the label. No AI model runs; nothing is uploaded.
AQI Calculator
Convert PM2.5, PM10, ozone, CO, and NO2 readings into the U.S. EPA Air Quality Index using the current breakpoints, including the 2024 PM2.5 update, or look up the concentration behind any AQI value.
Bortle Scale & Light Pollution Calculator
Enter an SQM reading or a naked-eye limiting magnitude to get your Bortle class, how much brighter your sky is than natural darkness, what you can see, and what the skyglow means for wildlife.
Carbon Offset Claim Checker
Paste a carbon-neutral or offset claim and an AI model in your browser lists what it says, its evidence and open questions. Free, private, no signup.
Climate Risk Brief Summarizer
Paste a climate risk brief and an AI model in your browser groups the hazards, cited figures and preparedness gaps. Free, private, no signup.
Commute Emissions Note Analyzer
Paste a commute note and an AI model in your browser pulls out distances, vehicles and fuel figures, plus lower-carbon options. Free, private.
Dew Point Calculator - Free Online Tool
Calculate your dew point with our free online tool. Get accurate results instantly. No signup required.
Electricity vs Tree Offset Calculator
Calculate the carbon emissions reduction achieved by switching to renewable energy versus planting trees.
Enhanced Fujita Scale Calculator
Convert an estimated tornado wind speed in mph, km/h or m/s to an EF rating, compare it with the original Fujita scale, and look up the wind range for any EF level.
EV vs ICE Emissions Calculator
Compare the carbon emissions of electric vehicles (EVs) and internal combustion engine (ICE) cars based on usage.
Flight Carbon Footprint Calculator
Calculate the carbon emissions from air travel.
Frost Date Calculator
Calculate your frost-free growing season from average last spring and first fall frost dates, with risk-adjusted planting dates for a cautious, typical or aggressive plan.
Greenwashing Language Detector
Paste a green marketing claim and an AI model in your browser flags vague wording and the proof each claim needs. Free, private, no signup.
Growing Degree Days Calculator
Total growing degree days from daily highs and lows with corn, soybean, wheat, alfalfa, cotton, and codling moth presets. Compare the simple average, the 86/50 modified method, and the single-sine method.
Heat Index Calculator
Calculate the feels-like temperature from air temperature and relative humidity using the National Weather Service heat index method.
Home Energy Note Classifier
Describe a home energy problem and a text model in your browser matches it to an area like insulation, windows or heating. Free, private, no signup.
Mulch Calculator
Calculate how much mulch you need in cubic yards, cubic feet and bags for one or more rectangular, circular or measured beds. Includes depth guidance and optional bulk or bagged cost.
Plant Hardiness Zone Finder
Find your USDA plant hardiness zone by ZIP code using the official 2023 USDA map data, or from your area's average annual extreme minimum temperature.
Raised Bed Soil Calculator
Work out how much soil fills your raised beds in cubic feet, cubic yards and bags, then split the total into ingredients for a 60/30/10, Mel's Mix or 50/50 recipe.
Recycling Photo Sorter Preview
Photograph an item and an image model in your browser names it and suggests a recycling stream. Check local rules. Free, private, no upload.
Snow Day Calculator
Estimate the odds of a school closure or delay from forecast snowfall, timing, temperature, ice, wind and how used to snow your region is. A transparent heuristic estimate, not an official announcement.
Soil Texture Triangle Calculator
Classify soil into one of the 12 USDA texture classes from sand, silt and clay percentages, and see the point plotted on the soil texture triangle.
Sustainable Swap Suggester
List everyday habits and an AI model in your browser suggests a practical lower-waste or lower-carbon swap for each. Free, private, no signup.
Topsoil Calculator
Estimate how much topsoil to order in cubic yards, bags and tons for a new lawn, a topdressing or a garden bed. Includes a settling allowance and an editable soil density.
Utility Bill Emissions Tagger
Paste utility bill usage lines and an AI model in your browser tags each source with quantity, unit and period for an emissions calculator. Private.
VPD Calculator (Vapor Pressure Deficit)
Calculate leaf and air vapor pressure deficit from air temperature, relative humidity and leaf temperature, with a color-banded VPD chart for propagation, vegetative and flowering stages.
Weather Alert Priority Classifier
Paste a weather alert and an AI model in your browser lists hazards, timing and who is at risk, and rates urgency. Free, private, no signup.
