Como você pode medir a pegada de carbono usando LCA?

Life Cycle Assessment (LCA) is a methodology used to measure the carbon footprint of a product or process comprehensively. It involves assessing the environmental impact across all stages of a product's life cycle, including raw material extraction, manufacturing, distribution, use, and end-of-life disposal. To measure carbon footprint using LCA, quantify the greenhouse gas emissions associated with each stage, considering factors like energy consumption, transportation, and waste. Use emission factors, which are standardized values for different activities, to convert resource use into carbon equivalents. LCA tools and software can facilitate this complex analysis.

LCA is a method that is used to assess how a product or service throughout its life cycle, from raw material extraction to production, use, and disposal, has an impact on the environment. Identifying the carbon hotspot in a product value chain using the LCA methodology will help you as a business owner get the data and insights to help communicate with stakeholders on how to implement reduction strategies.

Carbon Footprints are based on LCA methodology and enable Industries to quantify greenhouse gas (GHG) emissions for each stage of their product lifecycles. A sustainability expert can guide through the calculation process or perform CFs, helping in identifying carbon hotspots in the products’ value chains. This provides the industries / companies with data-driven insights for communicating with the suppliers, customers and other relevant stakeholders to achieve emissions reductions and advance decarbonization strategy toward a net–zero goal.

Life Cycle Assessment (LCA) emerges as a beacon in the realm of sustainable practices, offering a systematic and all-encompassing perspective on a product's journey from inception to conclusion. This meticulous approach takes into account every facet, weaving together the intricate threads of raw material extraction, manufacturing, distribution, utilization, and eventual disposal or recycling. These measurements take place within system boundaries, which are defined by the person performing the LCA. LCA is a rather flexible set of methodologies that can be used for impact measurement, including Carbon Footprints.

Life Cycle Assessment (LCA) quantifies the carbon footprint by analyzing the environmental impacts of a product or service throughout its entire life cycle, from raw material extraction to disposal. It assesses emissions associated with production, transportation, use, and end-of-life stages. By collecting data on energy consumption, material usage, and emissions at each stage, LCA calculates the total carbon footprint, providing a comprehensive understanding of environmental impacts and enabling informed decisions for mitigation strategies.

When calculating CO2 in the life cycle assessment, the transportation of goods from the sourcing of raw materials to processing / production and distribution is often not taken into account. The transportation sector accounts for around 20% of THG and has a significant impact on the product carbon footprint. Over the last 10 years, the European standard EN16258 and the ISO14083 version, which has been updated in 2023 and allows for international accounting, have proven to be effective for calculation purposes. The new version also takes transshipment into account. Professional tools ensure that the correct emission factors are used, the allocation to orders is correct and the biofuel component is also correctly taken into account.

The first step in conducting a carbon footprint assessment through LCA is to clearly define the boundaries of the study. This involves determining the stages of the product life cycle that will be included, such as raw material extraction, manufacturing, transportation, use, and disposal.

Carbon footprint can be calculated by aggregating carbon emissions through carbon accounting at all stages of a product with defined system boundary and scope. After inventorization, assessment can be done by using life cycle impact assessment and finally interpreted in terms of carbon footprint.

Carbon Footprint is a part of all common software solutions for Life Cycle Assessment. In accordance with ISO 14040, the aim and scope of the study must first be defined. In the second step, Life Cycle Inventory, the model that is suitable for determining the carbon footprint with the defined scope must be simply selected.

Measuring carbon footprint using Life Cycle Assessment (LCA) involves: Defining the Scope: Select the product, service, or process and its life cycle stages. Inventory Analysis: Gather data on energy and materials used, and emissions at each stage. Emission Calculation: Calculate greenhouse gas emissions for each stage, converting to CO2 equivalents. Interpretation: Analyze results to identify high carbon footprint stages and potential improvements.

To measure carbon footprint using LCA: first you have to define goal and scope, conduct Life Cycle Inventory, calculate emissions, collect data on energy/material/water usage, allocate shared burdens, assess impacts, interpret results, normalize and benchmark, identify improvement opportunities, document findings transparently, and consider third-party verification. This approach enables informed decision-making for sustainability benchmarking and improvements.
