About this calculator
The grid carbon intensity calculator estimates CO₂ emissions from electricity consumption in Brazil. Using ~90 g CO₂/kWh as an average, it accounts for the country's energy mix, including renewable sources (hydropower) and fossil fuel-based thermoelectric plants.
It applies the formula: total emissions = consumption (kWh) × carbon intensity (g CO₂/kWh). For example, 100 kWh would result in ~9 kg CO₂. Suitable for calculating carbon footprints of businesses, households, or sustainability projects.
Use it when comparing energy providers, planning transitions to clean sources, or assessing new equipment impacts. Note that intensity varies regionally based on local energy sources. Official data from Brazil's Court of Auditors and MME is used as a reference.
For precision, consult regional or provider-specific data. This calculator provides a useful approximation but shouldn't replace detailed emission inventory analyses.
Frequently asked questions
How does the calculation formula work?
The formula is total emissions = consumption in kWh × carbon intensity (~90 g CO₂/kWh). The intensity reflects Brazil's average energy mix, including renewable and non-renewable sources.
Why does intensity vary by region?
The mix of energy sources (e.g., hydropower in southern regions vs. thermoelectric plants in northern regions) affects values. Each region has different proportions of clean and polluting sources.
Is the result exact?
It's an approximation based on national data. For precision, use region-specific or provider-specific energy mix information.
How to use this to reduce emissions?
Compare providers with different energy mixes, choose renewable energy sources, or promote energy efficiency in your home or business.
