Materiality Assessment

Prioritizing what’s important to our sustainability strategy

Stakeholder engagement

We proactively engage with key external and internal stakeholders to identify the most material sustainability-related topics and metrics for enterprise-wide sustainability strategy, as well as public disclosure. Consistent with Global Reporting Initiative (GRI) guidelines, our selection of stakeholders to engage is based on five criteria pertaining to their relationship with Trane Technologies:

  1. Responsibility
  2. Influence
  3. Proximity
  4. Dependency
  5. Representation

External stakeholders include customers, supply chain partners, industry groups, non-governmental organizations (NGOs), investors, External Sustainability Advisory Council members, rating agencies and regulators. Internal stakeholders include leaders of business units and functions, Internal Sustainability Council members and employees. We engage with these stakeholders through interviews and surveys, augmented by benchmarking and desktop research.

We consistently work to synthesize GRI sustainability indicators and materiality criteria with metrics we believe are relevant and material to Trane Technologies and its stakeholders. In addition, these materiality indicators mirror the feedback and insights we gather through ongoing external and internal stakeholder interactions at every level and at all our locations around the world.

We considered the following sustainability topics in our materiality assessment:

Environment

  • Climate Change
  • Greenhouse Gas (GHG) Emissions
  • Energy
  • Water Use
  • Waste
  • Resource Use and Circular Economy
  • Energy Efficient and Low-Emission Products
  • Nature and Biodiversity
  • Pollution

  • Employee Benefits and Wellness
  • Inclusive Workplace
  • Human Rights
  • Occupational Health and Safety

Governance

  • Business Integrity and Oversight

Topic prioritization

Our priority topics guide our sustainability strategies, initiatives, enterprise risk intelligence and commitments. Some of the highest priority material topics for our business include Greenhouse Gas (GHG) Emissions, Energy, Energy Efficient and Low Emissions Products and Climate Change.

We take an active approach to maintaining, managing and monitoring all sustainability topics relevant to Trane Technologies, including those that lie outside our highest priority classification. Over time, our focus on these topics may shift due to stakeholder interests or business opportunities, among other factors. We update our materiality assessment regularly to ensure our sustainability strategies remain relevant, targeted and impactful.
