Harri Timonen - SEA Case Story

Harri Timonen, SEA is a Sustainability Consultant in Lisbon, Portugal. He recently launched his own consulting business to add additional possibilities to offer sustainability knowledge and services onsite or remotely.

What brought you to this moment in your career where the Sustainability Excellence Associate (SEA) credential made sense for you?


My sustainability journey started roughly ten years ago. I found studying again when I moved abroad in my late thirties. I started to study for a master's in development management because I wanted to understand the real reasons behind the last financial crisis, not only from a banking perspective (I have worked in banks) but from economic and social perspectives. Hence, I gained a Postgraduate Diploma in 2014. During my studies, I came across the corporate social responsibility concept, and I immediately was keen to know more. 


For someone who had only worked in the private sector, it seemed something I could relate to and I recognised common matters which overlap with enterprise risk management. However, I couldn’t find any globally recognised CSR certification. But, I discovered the ISSP website and I decided to study for the SEA certification on my own while I was working. I remember writing all the key terms, acronyms, events, organisations, etc. on post-it notes and putting them in sensible groups. As you know, there are quite a few terms to learn. I had four walls full of those notes grouped in different colours. (If only I had known this technique when I was in high school.) I achieved my SEA certification in March 2018, which now feels like ages ago. So much has happened since, both personally and globally, as we all know. And, also in the sustainability field. During the pandemic, I continued my studies and earned certifications in green project management (2020) and the GRI sustainability professional (2021). Furthermore, there is quite a lot going on around sustainability reporting, and I deepened my knowledge with various standards and frameworks such as GHG Protocol, TFCD, and TFND. Additionally, the EU CSRD directive and standards will come into effect next year. The ISSB standards will follow soon after. The ISSP SEA has provided a solid foundation for all of my later studies.


How are you putting the knowledge, skills, and ability demonstrated in the SEA to work in your career (or work) today?


During the pandemic, I was fortunate enough to be able to work from home with a laptop. I decided to continue my studies to connect the dots between sustainability, enterprise risk management, data analysis, and project management. I have previously worked as a risk consultant, and I am able to bring many things from there to sustainability. The risk and opportunity assessment workshop structure can also be modified to identify materiality issues, and business continuity planning and impact analysis improve organizational resiliency. Furthermore, the workplace equity plan and occupational health and safety plan can improve employee satisfaction and reputation. Scenario analysis is a risk management technique that has gained a lot of publicity due to recognition in the finance sector and science-based initiatives.


As we all know, there exist so many best practices, frameworks, standards, etc. At least I was a bit confused and needed to figure out the big picture. Thus, earlier this year, I began writing LinkedIn articles to share my understanding of known best practices. It has been a great way to summarise my thoughts in a way which others would understand too. It will be beneficial to me in future positions and projects, as I am currently designing my own consulting business. Starting my business ended one studying era, and I am excited to put my new skills and knowledge into practice.


What advice do you have for newcomers to this sustainability work?


Firstly, a career change can be overwhelming as there are other things in life as well. When things don’t go as planned, be gentle with yourself. Keep moving towards your goal, even if it is just a few small steps at a time. Take advantage of your earlier experiences and knowledge. Consider your previous working experiences, hobbies, and other interests and how you could combine them with sustainability matters. You may discover surprising connections and things that you already know. For example, for a long time, I was unsure how I could use my earlier experience in risk management and banking with sustainability. However, sustainability reporting brought all of those together, and the finance sector is also beginning to understand that our planet is important too.


Secondly, don't be discouraged by all the new terms, acronyms, and organizations. There are so many of them, and more are likely to come if the past can be used as an indicator. However, you should build your own understanding of various concepts and keep yourself updated. Don't overwhelm yourself, but instead pick some newsletters, news sites, and organizations to follow.


Lastly, I find watching nature documentaries soothing. Since childhood, I have enjoyed them, and during the pandemic, they had a nice calming effect amid the same bad news every day. You can travel back in time to the places you have visited in real life, or even learn a language with them.

March 23, 2026 I spend a lot of time thinking about how we teach sustainability. Not just the what , but the how and why . At TripleWin Advisory , a woman-founded, -owned, and -led sustainability consultancy and registered public benefit company, we believe real progress on circularity requires more than good intentions. It requires practitioners who are genuinely equipped to act. That conviction is what led us to develop two courses now available through ISSP: Cultivate and Mitigate . Both courses have since been adopted by universities and are reaching sustainability students across the country. Knowing what went into building them makes me want to share the story behind each one. Mitigate: Built From Practice, Not Textbooks Mitigate was created from hands-on work with partners tackling one of the most pressing issues in sustainability: food waste. Reducing food waste is consistently ranked among the highest-impact solutions to climate change, and yet it remains one of the most underfunded and under-addressed areas in the field. TripleWin Advisory has worked with the World Wildlife Fund (WWF) and the Pacific Coast Food Waste Commitment (PCFWC) , a public-private partnership whose frameworks were ultimately adopted at the national level. Those assets, that research, and those hard-won insights form the backbone of Mitigate. When we talk about food waste reduction strategies in this course, we're drawing on frameworks that have been tested and refined in real supply chains and policy environments. For learners who want to do this work professionally, that grounding matters. The University of Wisconsin has integrated Mitigate into their undergraduate and graduate sustainability programs, which speaks to what the course offers academically: rigorous, applied content that bridges the classroom and the field.

February 20, 2026 As someone who works closely with sustainability practitioners and leaders, I constantly hear the same themes: “How do I get leadership to say yes?” “How do small businesses realistically do this?” “How do we scale change without burning out?” That’s exactly why I’m so excited about our upcoming webinar and working sessions. These aren’t theoretical discussions. They’re practical, interactive, and designed for those of us doing the hard work of driving sustainability forward — often without formal authority, large budgets, or perfect systems. Here’s what’s coming up and why I believe these sessions matter right now! Webinar: The advantages and challenges for small businesses in sustainability March 5, 12:00pm EST REGISTER HERE We often center sustainability discussions on large corporations. ESG frameworks. Reporting mandates. Multi-billion-dollar net-zero commitments but small businesses make up the majority of our economy. In our upcoming webinar, The Advantages and Challenges for Small Businesses in Sustainability , Colleen Spear brings clarity and practicality to this often overlooked audience. As the founder of Spearpoint Strategies in New England, Colleen works directly with small businesses across industries — from bottle manufacturing to law to clothing design. She helps organizations embed sustainability into operations and strategy through certification support, fractional management, and strategic planning. This session will explore: The barriers small enterprises face in sustainable business spaces Why most sustainability advice overlooks small business realities The natural strengths small businesses possess How to apply sustainability practically within constrained environments Small businesses often lack the complexity — and bureaucracy — of larger corporations. That agility can be a major advantage. Decision-makers are accessible. Values can be integrated quickly. Cultural shifts can happen faster. Rather than positioning small businesses as behind, this session reframes them as powerful drivers of innovative, community-centered solutions. If you work with small enterprises, advise them, or operate one yourself, this webinar will provide actionable insights and language you can apply immediately. Webinar: Influencing Up: Strategies for Sustainability Leaders April 28, 5:00pm EST REGISTER HERE Our upcoming session with Dr. André Taylor, Strategies for ‘Influencing Up’ as a Sustainability Leaders , focuses on one of the most critical — and underdeveloped — skills in sustainability work: influencing without authority. Dr. Taylor brings a powerful combination of experience. He began his career as an environmental manager and scientist before earning a mid-career PhD in leadership at Monash University. Today, he serves as Leadership Specialist and Adjunct Associate Professor at the International WaterCentre and works extensively with sustainability and executive leaders. Why does this matter? Because sustainability practitioners rarely have direct authority over finance teams, executives, procurement departments, or policymakers. Yet we are expected to influence all of them. This session will explore: How to gain buy-in from senior leaders How to navigate functional silos How to influence across sectoral boundaries How to build authority when you don’t have the title What I appreciate most about this session is that it reframes influence as a skill — not a personality trait. We’ll dive into practical tools and concepts that help sustainability leaders: Speak the language of decision-makers Align initiatives with strategic priorities Understand motivations and incentives Work effectively across power dynamics If you’ve ever felt stuck waiting for approval, resources, or executive sponsorship, this webinar is designed for you. Implementing the AIMS Framework: From Momentum to Scale Four Interactive Working Sessions: March 18th (12pm EST) | Amplify REGISTER HERE April 22nd (12pm EST) | Influence REGISTER HERE May 12th (12pm EST) | Multiply REGISTER HERE June 25th (12pm EST) | Scale REGISTER HERE For those ready to go deeper, we’re offering a four-part interactive working series led by Dr. Jacqueline Kerr. Dr. Kerr has been published in Harvard Business Review and is in the top 1% of cited social scientists worldwide. Her work blends behavior change, implementation science, and systems thinking to help sustainability leaders deliver results — even in resource-constrained settings. These sessions aren’t passive webinars. They’re Miro-based, hands-on working sessions built around real initiatives participants are leading. Here’s how the journey unfolds: AMPLIFY — Recognizing Hidden Success We begin by mapping sustainability wins — even small ones — and identifying their ripple effects. Participants will: Surface hidden ROI Identify informal impact makers Recognize patterns across companies Publicly commit to amplifying a success story Key insight: change is already happening — it’s just often invisible. INFLUENCE — Removing Barriers Without Authority We diagnose stalled initiatives using an Action Audit framework. Together, we map barriers across: Strategy & Design People & Engagement Systems & Structures Feedback & Adaptation Participants will leave with: Clear barrier diagnoses Peer-tested influence strategies Commitment to remove one key blocker The big realization here? Most stalled initiatives are people challenges embedded within unsupportive systems. MULTIPLY — Creating Action Hubs We explore what makes groups succeed versus stall and design collaborative “action hubs” around shared problems. Participants will: Identify high-impact problems worth solving together Map who needs to be involved Develop invitation language Learn facilitation tactics that build ownership When groups co-design solutions, momentum becomes self-sustaining. SCALE — Building Systems That Spread Change Finally, we design pathways for scaling impact beyond individual teams. We’ll: Map where wins can spread Identify facilitator pipelines Explore how peer networks enable growth Commit to developing new leaders The insight here is transformative: when you train facilitators and activate system levers, change no longer depends on one sustainability champion pushing relentlessly. Why These Sessions Matter Now Across sectors, sustainability professionals are navigating political tension, budget constraints, competing priorities, and burnout. What excites me about this lineup of upcoming webinars and working sessions is that they address the real work: Influence without authority Practical sustainability in small enterprises Behavior change and implementation Scaling change through systems, not heroics These experiences are designed not just to inform — but to equip. Whether you're looking to sharpen your executive influence, support small business transformation, or move from isolated wins to systemic impact, there’s a session built for you. And perhaps most importantly, these sessions create community. You won’t just learn frameworks — you’ll see patterns across organizations, borrow strategies from peers, and build networks that last beyond a single meeting. If you’re serious about driving sustainable change in 2026, I invite you to join us. We’re not just talking about sustainability. We’re building the leadership capacity to deliver it.

January 16, 2026 At the International Society of Sustainability Professionals (ISSP), strategy is not theoretical. It is practical, action-oriented, and grounded in the real needs of sustainability professionals working in complex and rapidly evolving environments. The ISSP 2026 Strategic Plan is a one-year, execution-focused roadmap designed to strengthen ISSP’s role as a global professional association for sustainability practitioners. Built directly from member feedback gathered through Town Halls, surveys, and ongoing conversations, the plan focuses on three strategic priorities: financial stability, relevant professional knowledge, and meaningful member engagement. This article explains what the 2026 Strategic Plan is, why these priorities matter, and how member input directly shaped ISSP’s direction. What the ISSP 2026 Strategic Plan Is—and Is Not The 2026 Strategic Plan is not a long-term vision statement or a five-year forecast. It is a focused, one-year plan designed to deliver measurable progress. The plan is intended to: Strengthen ISSP’s financial sustainability Modernize sustainability education and credential resources Improve the member experience across career stages Each priority includes defined actions, timelines, and success metrics, ensuring accountability and transparency.
