   1. ‌Our ESG Commitments

      As we strive to integrate ESG best practices throughout our real estate investment, development, asset, risk and talent management processes, we commit to:

      1. ‌Environmental Sustainability

         We are committed to achieving Net Zero greenhouse gas emissions across our operations and value chain by 2050 in line with the Paris Agreement's 1.5°C pathway Ireland's Climate Action Plan. This includes the setting of science-based emissions reduction targets across Scopes 1, 2, and 3 and embedding Net Zero Principles into our decision-making, procurement and operational strategies. To reach Net Zero, we will:

         • Implement energy efficiency measures across our assets

         • Procure renewable energy sources and low-carbon technologies

         • Engage suppliers on sustainability, and take other actions across our value chain.

         • Integrate circular economy principles to reduce waste and resource consumption

         • Prioritise low-carbon materials and design in new developments and refurbishments

           Our climate strategy also supports the UN Sustainable Development Goals (SDGs) particularly those related to climate action (SDG 13), and partnerships for the goals (SDG17). We will report annually on our emissions reduction progress and related SDG contributions in our annual Sustainability report.

           We recognise the environmental impacts of real estate and construction and our responsibility to minimise our carbon footprint. We commit to aligning our ESG Management System to ISO40001 for environmental management. We will track, monitor and report on (where data capture is possible), and work to reduce energy, water, waste, and materials consumption across our portfolio. New developments and major renovations will utilise sustainable design and construction practices, including renewable energy, electric vehicle charging, sustainable materials selection, and waste diversion goals.

           We recognise the importance of transitioning to a circular economy that designs out waste, pollution, and carbon emission. To embrace circular economy principles, we will select recycled, recyclable and responsibly sourced materials with low embodied carbon, enable closed-loop approach, design for flexibility and adaptation, engage residents and OMCs on waste reduction, collaborate with vendors to recover and divert waste from landfill, and minimise total waste generation across our portfolio. We will raise awareness and work with stakeholders across our value chain to improve resource efficiency, reduce waste, conserve embedded energy in materials, design for the future, and procure responsibly.

           We will assess climate-related risks and opportunities across our portfolio according to applicable regulatory guidelines or frameworks. Climate resilience considerations, including flooding, heat, and energy security will be evaluated and addressed at both existing and new assets.

           We recognise the importance of protecting and restoring biodiversity and natural habitats. We will identify opportunities to enhance native landscaping, improve biophilia and support local ecosystems, where practicable.

      2. ‌Social Sustainability

         We are committed to serving our communities and creating positive local social impact. We will support local communities, economic development, and sustainability initiatives through partnerships, volunteer programs, donations, and sponsorships. Our charitable giving will align with community needs assessments and input from local stakeholders.

         Our buildings aim to enhance health, wellness and quality of life for residents. We will enhance features of our portfolio including access to daylight, ventilation, air quality, circular economy, and connections to nature, where practicable. Our stakeholder engagement strategy includes regularly collecting feedback from residents and partners. We will regularly engage with key stakeholders to ensure we are aware of, and are able to respond to, their expectations.

      3. ‌Governance

Our Board oversees ESG strategy and performance through a dedicated Sustainability Committee. Elements of executive compensation will be linked to ESG goals to demonstrate accountability to our commitments. We will conduct ethical business practices throughout our operations and supply chain by implementing robust anti-corruption, human rights, whistleblowing, supplier code of conduct and responsible sourcing policies.

We believe that good governance practices are essential to a successful and sustainable business, and therefore we ensure that they are integral to us. We
