Carbon & ESG FAQ hub
Long-form answers on footprints, calculations, ESG basics, transport, electricity, renewables, and industry benchmarks—each page links to our free calculators and related guides so you can go from reading to modeling in minutes.
- What is a carbon footprint? Learn what a carbon footprint measures, how CO2e differs from CO2, which activities count, and how to model your footprint with a free calculator.
- How to calculate a carbon footprint Step-by-step guidance for calculating a personal or small-business carbon footprint using activity data, emission factors, and sanity checks.
- What is ESG reporting? Understand ESG reporting goals, common frameworks, how environmental data fits in, and how calculators complement—not replace—disclosures.
- What does ESG stand for? ESG means Environmental, Social, and Governance. Learn what each pillar covers and how it connects to carbon tools you can run today.
- How do businesses reduce carbon emissions? Practical levers for businesses: efficiency, electrification, travel policy, logistics, renewable procurement, and employee engagement—with calculator links.
- What activities produce the most carbon emissions? See which personal and business activities usually dominate carbon footprints, why context matters, and how to test your own mix in a calculator.
- How is CO2 emission calculated? Understand activity data, emission factors, renewable adjustments, and how calculators convert usage into kg CO2e.
- What is Scope 1, Scope 2, and Scope 3 emissions? Learn GHG Protocol scopes: direct emissions, purchased energy, and value-chain emissions—with examples and calculator links.
- How can I lower my carbon footprint? Prioritized actions to lower a personal carbon footprint: mobility, home energy, diet, consumption, and offsets—with calculator experiments.
- What is the average household carbon footprint? How national averages are built, why your household may differ, and how to benchmark responsibly using calculators.
- How does electricity usage affect carbon footprint? Grid intensity, renewable share, time-of-use nuances, and how to model household electricity emissions accurately.
- How much CO2 does a car produce? Estimate car CO2 from distance, fuel type, and efficiency; compare petrol, diesel, and EV grid scenarios with calculator links.
- What is a net zero carbon goal? Understand net zero versus gross zero, residual emissions, offsets, and how households can align actions with science-informed pathways.
- How do renewable energy sources reduce emissions? Wind, solar, hydro, and geothermal displace fossil generation; learn modeling limits and how to reflect renewables in calculators.
- What is carbon offsetting? Learn how carbon offsets work, quality signals, additionality, permanence, and why offsets complement but rarely replace reductions.
- How does air travel impact carbon footprint? Why flights dominate many footprints, radiative forcing basics, class factors, and how to model trips in calculators.
- What is an ESG score? How ESG scores are built, why ratings disagree, and how our educational ESG calculator differs from institutional ratings.
- Why is ESG important for companies? Capital access, regulatory trends, employee retention, and customer trust—why ESG data increasingly shapes business outcomes.
- How does solar energy reduce carbon emissions? Generation vs avoided grid emissions, inverter losses, embodied carbon, and how to reflect solar in household calculators.
- What industries have the highest carbon emissions? Sector-level overview: power, cement, steel, chemicals, aviation, and agriculture—plus why rankings shift with boundaries.
