Carbon footprint is a measure of the impact human activities have on the environment in terms of the amount of greenhouse gases produced, measured in carbon dioxide equivalents.

Nitrogen (N2) is not a greenhouse gas, as it does not absorb and trap heat in the atmosphere like other greenhouse gases.

Landfills are a major source of methane due to the decomposition of organic matter, such as food scraps and paper products, in the absence of oxygen.

While planting trees can help absorb carbon dioxide from the atmosphere, it is not directly related to reducing carbon footprint, which focuses on reducing greenhouse gas emissions.

Recycling is the process of converting waste materials into new materials and objects, reducing the use of raw materials and energy.

Recycling actually helps reduce the amount of waste sent to landfills, thereby conserving landfill space.

Composting is the process of breaking down organic matter, such as food scraps and yard waste, into a nutrient-rich soil amendment.

Composting does not directly generate electricity.

Incineration is the process of burning waste materials at high temperatures to reduce their volume and produce energy.

Incineration actually helps reduce the amount of waste sent to landfills.

Landfilling is the process of disposing of waste materials by burying them in the ground.

Landfilling does not directly generate renewable energy.

Waste footprint is a measure of the amount of waste produced per person or household.

Reducing waste footprint involves reducing consumption and waste, not buying more products.

Eco-design is the process of designing products and services to minimize waste and environmental impact throughout their life cycle.
