Each year, Earth Day highlights the urgent need to protect our planet and rethink our relationship with the natural world. As climate change accelerates and biodiversity continues to decline, the way we design, build, and manage infrastructure is becoming increasingly critical.
Transport and energy systems are essential to our societies, enabling mobility, connectivity, and economic growth. At the same time, they exert significant pressure on ecosystems, contributing to habitat fragmentation, land use change, and biodiversity loss. Addressing these challenges requires not only reducing impacts, but also transforming how infrastructure and nature coexist.
This is where SYMBIOSIS plays a key role.
From impact mitigation to ecosystem integration
Aligned with global calls for action such as those promoted by the United Nations Environment Programme, SYMBIOSIS aims to transform how biodiversity is considered in transport and energy infrastructure. Instead of approaching nature as a constraint to be mitigated, the project promotes a perspective in which biodiversity is fully integrated into infrastructure planning, operation, and renewal. This reflects a broader transition towards nature-positive development, consistent with:
- SDG 13 (climate mitigation and resilience)
- SDG 15 (ecosystem protection and restoration)
- SDG 9 (sustainable infrastructure systems)
By bringing together partners from across Europe, SYMBIOSIS combines expertise in transport, ecology, engineering, and policy to develop practical tools and approaches. These support infrastructure managers and decision-makers in embedding biodiversity into their daily practices and long-term strategies.
The project addresses this challenge throught a set of complementary actions including biodiversity monitoring, nature-based solutions, policy alignment, and stakeholder engagement reflecting the need for coordinated and cross sectoral approaches.
Building nature-positive infrastructure
In line with UNEP’s emphasis on ecosystem restoration and pollution reduction, SYMBIOSIS contributes to the transition towards nature-positive infrastructure, where transport and energy systems not only minimise environmental impacts but actively support ecosystem restoration and resilience.
This transition requires embedding biodiversity into decision-making from the earliest planning stages and throughout the full infrastructure lifecycle. It is supported by strengthening enabling frameworks, including transport policies, environmental impact assessment procedures, corporate sustainability reporting.
In parallel, the project develops practical tools and approaches to enhance biodiversity while improving infrastructure resilience, performance, and cost-effectiveness. These efforts are complemented by advances in environmental data collection, monitoring, and analysis, enabling more informed and forward-looking decisions.
SYMBIOSIS also fosters communities of practice, bringing together rail operators and key stakeholders across Europe to harmonise biodiversity data and support the development of a shared and scalable framework beyond the rail sector.
Together, these actions contribute to more integrated, resilient, and sustainable infrastructure systems that better balance societal needs and environmental protection.
A collective effort for systemic change
Echoing the UNEP message that environmental progress depends on both individual and systemic action, Earth Day is also a reminder that meaningful progress depends on collective action. Governments, infrastructure managers, industry stakeholders, researchers, and civil society all have a role to play in shaping more sustainable systems.
SYMBIOSIS actively contributes to this dynamic by fostering collaboration and dialogue among these different actors. Through stakeholder engagement activities and knowledge-sharing initiatives, the project helps ensure that solutions are grounded in real-world needs and can be effectively implemented across different contexts.
Looking ahead
As we mark Earth Day, the need to align infrastructure development with environmental objectives is clearer than ever. Protecting biodiversity and addressing climate change must go hand in hand with the evolution of our transport and energy systems.
SYMBIOSIS contributes to this transition by providing the knowledge, tools, and collaborative framework needed to support more sustainable decision-making.
By bridging the gap between science, policy, and practice, the project helps lay the foundations for infrastructure systems that are not only efficient and resilient, but also better integrated with the natural environment.
