Biodiversity, a key environmental issue

Scroll

Biodiversity is the cornerstone of our economy and society. It is defined as diversity between species, within species, ecosystems and their interactions. Biodiversity and nature’s benefits to humanity influence almost every aspect of human development and are essential to achieving the United Nations’ Sustainable Development Goals (SDGs). They contribute to food production, water purification, climate regulation, and disease control, called ecosystem services. However, these resources are being depleted and degraded much faster than at any other time in human history, almost exclusively due to human activities.

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) estimates that 50% of global GDP will be affected by biodiversity loss. In this respect, biodiversity is crucial and at the heart of the business model of companies, since they benefit from ecosystem services. The erosion of biodiversity affects the functioning of these services and poses a threat to financial stability.

Integration in the investment analysis process

Sienna IM integrates biodiversity-related issues into its extra-financial analysis processes.
This involves the application of exclusion policies (tobacco, unconventional oil, etc.) and the evaluation of companies’ practices with regard to biodiversity.
Each expertise (listed assets, private debt) applies a specific methodology that includes biodiversity analysis criteria in ESG scores and in the analysis of controversies

Engagement

Sienna IM prioritizes engagement over dialogue over exclusion.
It participates in working groups and collective initiatives such as SPRING and Finance for Biodiversity Pledge.
It establishes partnerships such as the ecological accounting chair at Agro Paris Tech.

Monitoring Impact

Calculation and annual monitoring of the biodiversity footprint of Sienna IM investments.
Measured via Mean Species Abundance (MSA), a metric provided by Iceberg DataLab since 2023.
From 2025, an analysis of sectors and emitters with a high biodiversity impact, with a comparative scoring in Km² MSA

Monitoring dependencies

Sienna is committed to mapping sectors dependent on ecosystem services as early as 2025.
The objective is to understand the financial risk associated with biodiversity loss and to improve knowledge of double materiality
