Carbon Footprint aspects

A carbon footprint is the total amount of greenhouse gases (GHGs) emitted directly or indirectly by an entity, product, service or event throughout its life cycle. It is expressed in tonnes of carbon dioxide equivalent (tCO₂e), a unit that lets the climate impact of different gases be compared on the basis of their global warming potential.

Greenhouse gases and the greenhouse effect

GHGs such as carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) trap heat in the atmosphere and raise global temperatures. This greenhouse effect is natural and essential for life, but its intensification by human activity is accelerating climate change.

Why measuring the carbon footprint matters

• Understanding the impact: it identifies the main emission sources and quantifies their contribution to climate change.
• Setting reduction targets: it provides the baseline for goals aligned with international agreements and national policies.
• Implementing mitigation: it reveals opportunities to cut emissions through energy efficiency, renewable energy and better resource management.
• Strengthening reputation: it lets companies demonstrate their commitment to sustainability and meet growing stakeholder expectations.

Carbon footprint scopes

The Greenhouse Gas Protocol, the most widely recognised international standard, defines three scopes:

Scope 1: direct emissions

GHG emissions from sources owned or controlled by the entity, such as fuel combustion in its facilities or vehicles. See Scope 1 emissions.

Scope 2: indirect emissions from energy

Emissions associated with the generation of the electricity, heat or steam purchased and consumed by the entity. See Scope 2 emissions.

Scope 3: other indirect emissions

All other indirect emissions across the value chain, including the supply chain, transport and distribution, business travel, product use and end-of-life. See Scope 3 emissions.

Measuring these scopes is the starting point for any credible reduction strategy. At Manglai we help companies measure their carbon footprint and prepare their sustainability reporting. Discover how Manglai can help you.
