What is iESG?

iESG is the SIERA Alliance’s strategic concept to foster a culture of environmental responsibility, sustainability and impact. iESG completes the ESG framework by combining it with real-world impact aligned to the SDGs.

Engineering for a Better Tomorrow

Developed by SIERA Alliance, iESG directs attention to the environmental engineering solutions for most pressing sustainability challenges across two core dimensions:

At its core lies the periodic table of impact, that highlights the complete list of services by SIERA Alliance members within the precise categories and subcategories.

Impact: Focused Action That Drives Change

iESG organizes impact into three priority areas where transformation becomes tangible.

Sustainable Infrastructure & Energy

Sustainable Infrastructure & Energy

We support resilient, efficient, and low-carbon infrastructure—from city-wide development to renewable energy and geotechnical safety. Services include infrastructure audits, energy systems optimization, ISO certifications, carbon footprint planning, and site investigations based on DIN standards.

Sustainable Cities & Municipalities

Sustainable Cities & Municipalities

We help transform cities through energy-efficient buildings, brownfield redevelopment, and circular site management. Our services cover DGNB-certified real estate, soil remediation, urban planning, and construction oversight that respects both environment and culture.

Impact Technologies

Impact Technologies

We harness AI, geospatial tools, and ESG software to power sustainability reporting and decision-making. From climate modeling to automated CSRD compliance, our tech solutions enable smarter resource use, transparent impact finance, and streamlined ESG performance tracking.

Environment

Climate

Climate

We support organizations in managing climate-related responsibilities through targeted services such as greenhouse gas management, climate protection strategies, and adaptation planning. This includes decarbonization roadmaps, emissions reduction initiatives, and future-proof infrastructure design to align with the ESRS E1 standard and contribute to the EU’s net-zero objectives.

Environmental Protection

Environmental Protection

Our environmental protection services focus on reducing pollution and mitigating environmental risks across project lifecycles. This includes managing building pollutants, rehabilitating contaminated sites, clearing explosive ordnance, and applying advanced environmental technologies—ensuring regulatory compliance and protecting ecosystems.

Water

Water

We offer integrated water management solutions that cover groundwater protection, surface and stormwater management, flood defense systems, and efficient urban water infrastructure. These services help companies use water responsibly, minimize risks, and meet ESRS E3 disclosure requirements.

Ecosystems

Ecosystems

Our ecosystem services aim to preserve and enhance biodiversity through nature and species protection, environmental planning, and ecological landscape design. We also support restoration and renaturation projects, helping organizations reduce their ecological footprint and safeguard long-term environmental resilience.

Circular Economy

Circular Economy

We enable companies to transition toward circular resource use through landfill modernization, waste and soil management, site remediation, refurbishment, and dismantling. These services support material efficiency, reduce waste, and align operations with the principles of a sustainable circular economy.

Social & Governance

Social & Governance

Social & Governance

For the Social and Governance part of the iESG, we offer tailored, on-demand training to help your teams confidently implement ESRS S1–S4, G1 standards. Our expert-led sessions combine practical guidance with real-world examples, reducing external dependency and building in-house capability.

We empower industries to explore the opportunities for market leadership through strategic transformation.
