About this calculator
The 'CO₂ Recycling Savings' calculator estimates the reduction of carbon dioxide (CO₂) emissions achieved by recycling materials. It uses specific coefficients for paper (-2.5 kg/kg), plastic (-1.5 kg/kg), and glass (-1 kg/kg), representing the emission savings per kilogram recycled compared to producing new materials. Simply input the amount of each material recycled to calculate the total environmental impact.
The formula multiplies the weight of the recycled material by its corresponding coefficient. For example, recycling 10 kg of paper avoids 25 kg of CO₂ (10 × 2.5). This tool is ideal for individuals, businesses, or organizations looking to measure the contribution of their recycling programs to sustainability.
Accurate data input is crucial, as materials with different coefficients significantly affect results. The calculator also helps identify which materials offer the highest environmental impact, encouraging focus on actions with the greatest ecological return.
Frequently asked questions
Why does paper have the highest CO₂ savings coefficient?
Recycling paper requires less energy than producing new paper from raw materials, significantly reducing emissions.
Can I calculate savings for multiple materials at once?
Yes, enter the amounts of paper, plastic, and glass separately. The calculator will sum the results automatically.
What if the recycled material isn't listed?
The tool currently supports paper, plastic, and glass. For other materials, refer to specific studies or suggest additions for future updates.
How to ensure input data accuracy?
Use official records from your recycling program or estimates based on your waste management reports.
