Convert emissions or energy data to the equivalent amount of carbon dioxide (CO2) emissions. The calculator helps you translate abstract measurements into concrete terms you can understand, such as the annual emissions from cars, households, or power plants. This calculator may be useful in communicating your greenhouse gas reduction strategy, reduction targets, or other initiatives aimed at reducing greenhouse gas emissions.

The Carbon Conscience tool is based on a broad research inquiry into embodied carbon in constructed landscapes. The app assists designers with evaluating proposed urban design and planning projects in respect to carbon-related impacts. The key metrics per land use (landscape, architectural, and ecological) considered are carbon emissions, storage, and sequestration.

This  web-based application allows registered users to estimate the carbon footprint and time to carbon neutral for landscape projects based on site design and management. Projects receive carbon feedback in the form of a Climate Positive Scorecard.  It may be used for projects in the design phase or already completed projects.

i-Tree is a state-of-the-art, peer-reviewed software suite from the USDA Forest Service that provides urban and rural forestry analysis and benefits assessment tools. The i-Tree tools can help strengthen forest management and advocacy efforts by quantifying forest structure and the environmental benefits that trees provide. i-Tree has nine core tools: ones for individual trees, tree canopy area, and tree planting. Try starting with i-Tree Eco.
