Our Clients
Whether you are a startup, an SME, or a large corporation, regardless of where your company position is on the sustainability journey - from the initial stages to striving for industry leadership - we are here to support you.
Real Estate Investment Manager
The client lacked a formal sustainability plan for their portfolio and faced increasing stakeholder expectations. We designed an energy efficiency and sustainable investment strategy targeting the top 45% of energy-consuming properties in the US. This solution delivered an 18% reduction in utility costs, 28% energy savings per property, and $77M in annual savings, while boosting portfolio value by $1.5B.
Real Estate Investment Trust
Facing a non-structured ESG program and pressure to meet investor expectations, the client needed a comprehensive solution. We developed a robust ESG program with clear strategies, policies, and objectives, improving their ratings and alignment with benchmarks. This work enabled cost-saving initiatives and led to their first ESG report, enhancing their market reputation and long-term sustainability strategy.
Investment Management Firm
Our GRESB Infrastructure reporting delivered transformative results in just one year. By enhancing data collection, strengthening policies, and optimizing management for over seven assets, we drove a 60%+ improvement in GRESB Infrastructure Asset Scores. This progress positioned their performance well above GRESB and peer averages, with two of their investment management firm’s infrastructure funds achieving top-tier ratings in a diversified portfolio. These standout assets now boast scores exceeding 90 points
Global Banking Group
Struggling with reputational damage and a lack of sustainability expertise, the client required robust policies and strategies. We developed sector-leading policies on sensitive industries and a multi-year sustainability strategy, working with NGOs and internal teams to ensure acceptance and implementation. These policies have since set industry standards and reinforced the client’s credibility in environmental and social responsibility.
International NGO
Limited resources hindered the client’s ability to produce an influential report on biodiversity financing needs. We co-conceptualized, researched, and authored Financing Nature: Closing the Global Biodiversity Financing Gap, in collaboration with leading organizations. This widely endorsed report shaped global discussions on biodiversity conservation funding and solidified the client’s leadership in the field.
Investment Bank
The client’s outdated framework for environmental and social risk management left them vulnerable to market changes and reputational risks. We collaborated with global stakeholders to revise the Equator Principles, creating a modernized framework now adopted by over 100 international banks. This positioned the client as a leader in sustainability risk management for infrastructure finance.
