A web application which enables users to keep a tab on their monthly Carbon footprint using their electricity, LPG, and fossil fuel usage data.

4 factors have been taken into account:

• Units of electricity (in KWh)- elec_units
• LPG consumed (in Kg)- LPG
• Petrol consumed (in L)- petrol
• Diesel consumed (in L)- diesel

Emmision factors for the above factors are extracted from trusted recources of -
Central Electricity Authority
Green House Gas Protocol

Emission_Factor_Electricity = 0.8 Kg/KWh;
Emission_Factor_Petrol = 2.296 Kg/L;
Emission_Factor_Deisel = 2.653 Kg/L;
Emission_Factor_LPG = 2.983 Kg/Kg;

Net Kg of CO2 can be calculated as the sum due to individual sources elec_cf + petrol_cf + diesel_cf + LPG_cf which when divided by 1000 will give the Tonnes of CO2.

We are following the policy which ensures that the more regularly a user reduces carbon footprint, the more rewards a he/she would receive. To maintain, a non overflowing, readable value of Total coins- the following factor has been used- 0.5 * streak * 100

This is multiplied to the difference of current and previous month's carbon footprint, and rounded of to the nearest integer-

add_to_balance = Math.round((past_cf - cf_basic) * scaling_factor);
