Carbon footprint aims to quantify the greenhouse gas emissions across the entire life cycle of an organization or product, identifying major emission sources. Based on international standards (GHG Protocol or ISO 14064), it systematically collects data on energy use, transportation, supply chains, and other areas to quantify greenhouse gas emissions and create a carbon emissions inventory. By analyzing key processes, it enables the development of science-based emission reduction pathways and action plans, promoting energy efficiency improvements, renewable energy substitution, and low-carbon operations. This supports the achievement of carbon neutrality goals and enhances environmental responsibility, reputation, and sustainable development capabilities.
