Eco Toolkit
How to use
What it does
A few small calculators about environmental impact and resource use: estimate the carbon emissions from a household's electricity, gas and travel, look up which bin a common item belongs in, estimate daily water consumption, and work out how many trees would be needed to offset a given amount of carbon. Useful for getting a rough sense of how much environmental load your everyday routine carries.
How to use it
Four calculators share the top of the page. The emissions estimator takes electricity units, gas usage and travel mode with distance item by item, then totals them and breaks down the shares; recycling search takes an item name and returns the bin and any caveats; the water estimator works from household size and habits; and the offset calculator converts an annual emissions figure into a number of trees.
FAQ
How accurate is the carbon estimate?
It sums whatever you enter for electricity, gas and travel, so it is an order-of-magnitude figure — useful for seeing which item dominates your footprint, not a substitute for formal carbon accounting.
How does the recycling lookup work?
Type an item name into the search box and it returns the right bin plus handling caveats — far more practical than memorising the sorting table.
How is the tree offset calculated?
Enter your annual emissions and it returns the number of trees. Treat the figure as theoretical; its value is building a sense of scale between a lifestyle and the trees it costs.
