“In my role, collaborating with OnePointFive on Climate Corps Foundations Week was a clear win for the fellows. Neil and Matthias led two 75-minute, practitioner-led workshops, one on renewable energy procurement and one on energy efficiency, and both were among the best-received sessions of the week.

What stood out to me was how practical and hands-on the training was: the activities OPF designed gave the fellows something they could actually apply, not just sit and listen to. The fellows I serve come in with a wide range of experience and go straight into their summer placements, so building real confidence quickly matters, and OPF delivered that. The feedback from fellows was outstanding, and both trainers were genuinely well-liked across the cohort. OPF clearly does this for a living, and it shows."

“Partnering with OnePointFive on our five-part green skills webinar series was a team effort that paid off. We saw around 600 registrants, and the sessions were high-quality, engaging for our audiences with thoughtful questions asked; plus, we received strong survey feedback, which outperformed past webinars we've run.

The content was well structured, practitioner-informed and academically grounded, which were important to us. As the sessions were recorded, we have been able to extend the value of these trainings through repackaging the content & co-marketing it together with OPF.”

“Since completing the program, I’ve already used the knowledge in real ways: from reviewing ESG reports of major Sri Lankan companies to engaging stakeholders on their climate commitments and understanding local policy impacts. These are conversations I simply wouldn’t have been able to lead before.

As a country director, I’m now better equipped to ask the right questions, strengthen partnerships, and connect our work in Sri Lanka to broader opportunities. The training has expanded both my perspective and my ability to act.”

“I was part of Cohort 3 of OPFA and started using what I learned in our company to drive emissions measurement and decarbonization decisions. The OPFA community has been a source of inspiration and information from day one through now. I’m still attending OPFA events and learning from everything the team and community share online.”

“I joined OPF Academy to bridge the gap between theory and practice. My degree didn’t give me the hands-on skills or network I needed, but OPF did. The OPF community helped me realize that climate work can happen anywhere—even in roles not explicitly labeled “sustainability.” I learned to stop boxing myself in and instead ask: How do I want to feel about my work? That led me to my new job.”

"As a company without in-house sustainability expertise, we needed a partner who could guide us through the EcoVadis submission process—and OPF delivered. They brought a structured, accountable approach that kept us on track and focused on real, tangible outcomes. What stood out most was their ability to translate complex sustainability goals into practical steps tailored to our size and capacity, always tying actions back to what would truly add value—not just in dollars, but in health, safety, and environmental impact. Thanks to OPF, we achieved an EcoVadis medal and now possess a meaningful roadmap for future enhanced sustainability and customer satisfaction”

“Working with OnePointFive has been exceptional. Their expertise, professionalism, and collaborative approach set them apart. OnePointFive demonstrated a deep understanding of our needs and through their guidance, Sarona is able to sharpen its climate lens. We now understand better the climate opportunities and risks across our portfolio. As an investor in emerging markets, we espouse transparency and accountability. We engage in impact measurement and management with our investees. After working with OnePointFive, Sarona is now confident and better equipped to develop its system for climate reporting and disclosures and align with evolving sustainability reporting standards for the private equity industry.”

“Even as I begin this new position, I’m already applying the knowledge I gained during the program. The slides, notes, and presentations continue to be a valuable resource—both for refreshing my memory and serving as examples in real-world scenarios. OPFA not only gave me the skills and confidence I needed but also equipped me with tools that will support my growth for years to come.”

“While in between jobs, I noticed gaps in my skills and experience that I wanted to address to support sustainability efforts more effectively. Certifications seemed overwhelming in terms of time and cost, but OPFA offered a practical and hands-on approach that resonated with me. Receiving a scholarship allowed me to participate in this impactful program, where I gained both technical skills and a supportive network of sustainability professionals.”

“The Academy gave me in depth knowledge of Corporate Sustainability such as CDP, ISO, LCA, and GHG it contained everything I needed to be knowledgeable to get internships and interviews, now I am putting this knowledge and my experiences to use during my interviews to land my first ever Sustainability-Climate role!”

“I now feel confident in guiding teams through the intricacies of sustainability projects, from setting clear goals to managing implementation and adapting strategies as needed”

“If you're seeking a career pivot, wanting to build your sustainability acumen, or looking to network with like-minded professionals, OPFA is a great opportunity to do all three”

“It’s often very hard to find climate experts in the space that can provide answers specifically on EEIO (Environmental-Extended Input-Output). The ability for us to dive deep with topic areas [with OPF] was really great—better than general sustainability consultants who cannot go as deep into environmental concepts. Working with OnePointFive was superb.”

“The knowledge experience of OPF’s founders in the Carbon space was the key driver [to work together]. They’ve found a niche and very few in the space could have delivered a quality piece of work and display the level of versatility that this team did. By the end of the workshop, most folks were up to speed on the key elements of the space that were relevant to making business decisions on, and how to participate in the space going forward."

"The program’s emphasis on holistic learning, practical applications, and collaboration with diverse stakeholders has prepared me to tackle complex sustainability challenges effectively. The supportive community and access to industry experts have been particularly beneficial, providing insights and inspiration that have shaped my vision for the future."

“OnePointFive supported the enhancement of our internal climate incubator, helping us create a strategic roadmap forward from concept to concrete plan. OPF’s expert insights and ability to synthesize complex research into actionable insights helped to move forward a project that our international nonprofit has been eager to invest in for a while.”

“Working with OnePointFive was like having an in-house sustainability team. The OPF team deeply understood KraveBeauty's vision, mission, and values, and reflected our ethos in developing a sustainability roadmap that's unique to us. They met us where we were by having the agility to bring on subject matter experts in each stage of execution.“

“OPF has extensive climate expertise across its diverse and growing global climate team from emissions modeling and climate policy, to climate reduction strategy building. Together, we will be able to make a tremendous impact by decarbonizing companies across the globe.”

“I contracted OnePointFive to run user interviews and insights gathering for our emissions reduction potential tool, CRANE. I appreciated how OPF worked seamlessly alongside our RhoAI team—managing the end-to-end interviewing process, and integrating insights into the final user report alongside our survey results. I look forward to partnering with them in the near future!”

“What I appreciated about OPF was the ease with which their team integrated into ours and how their style of work synced up with our organization. OPF’s team became an integral part of ours and cultivated a powerful trust that propelled us forward. Their expertise helped our organization orient towards an authentic and transformative trajectory.”
