Environmental metrics

Environmental footprints, Life Cycle Assessment (LCA), value chain approach, quantitative and qualitative indicators.

Do you want to integrate the environmental dimension into the development and communication of your products and services?
• Measure the environmental footprint
• Identify priority challenges of the supply chain
• Identify and prioritize improvement opportunities
• Compare different technologies and practices
• Compare different technical routes in agriculture
• Communicate the performance and benefits of your products

“Life Cycle Assessment” or LCA is the standardized reference method for quantifying environmental impacts and benefits of products and services throughout the value chain: from the extraction of raw materials to processing, packaging, transport, distribution, use and end of life (disposal, recycling).

The figure below presents the life cycle of a food product.

LifeCycle

LCA is a systemic and holistic approach. It covers the entire value chain and crosses different environmental aspects (climate change, air, water, soil pollution, use of resources).

It identifies hotspots in the value chain, and prioritizes improvement topics. LCA is the starting point for a circular economy approach.

It feeds eco-design, communication and strategic decisions of a sustainable business.

Sayari performs LCAs in accordance with international standards (ISO 14040 and 14044) as well as simplified LCAs. Contact us for more information.

Bio-based raw materials

Many industries use bio-based raw materials in their products. Whether it is cosmetics, food, biobased packaging, green chemistry…

In value chains of these products, the raw material part (agricultural production, plants, algae, seafood)  is  most of the time one of the hotspots of the environmental footprints.

• Life Cycle Analysis method allows a proper assessment of their carbon footprint.

• However, carbon footprint is not sufficient to grasp the whole environmental picture of various agricultural practices (quantity of inputs, fertilizers or pesticides; agro-ecology, etc.). Impacts on biodiversity and soil quality are not thoroughly addressed.

• Carbon footprint is not sufficient either for seafood. The impacts of overexploitation of some freshwater or marine species are not addressed.

For these products, we suggest supplementing the quantitative LCA with qualitative indicators. Based on our work on biodiversity, we developed additional qualitative metrics.
