Patrick Sherwin, founder and CEO of GoSun, explains why clean-energy technologies must deliver more than emissions reductions. Drawing on decades of experience with solar and distributed energy, he discusses solar economics, EV charging, resilience, manufacturing, efficiency, and product design, emphasizing that reliability, usability, realistic costs, and strong implementation ultimately determine whether climate technologies succeed.

Josh Harrison, Director of the Center for the Study of the Force Majeure at UC Santa Cruz, argues that climate adaptation requires systems thinking. Wildfire resilience depends on ecological forest restoration, viable uses for removed wood, local processing capacity, and long-term management. Mass timber can support lower-carbon construction, but only with responsible sourcing and traceability. In cities, green roofs, vegetation, stormwater systems and other nature-based infrastructure can reduce heat, flooding and energy demand, although permitting, financing and fragmented benefits remain major barriers to wider adoption.

In this Net Zero Compare podcast, Albert Slap, President of RiskFootprint, explains why physical climate risk should be treated as a practical property, financial, and operational issue, not just an ESG reporting concern. Traditional due diligence and flood-zone maps can miss important hazards, while single risk scores may hide severe exposures. Slap argues for property-level assessments that consider building vulnerability, potential damage, financial loss, and downtime. He highlights the ASTM Property Resilience Assessment as a framework for identifying hazards, evaluating vulnerabilities, and selecting cost-effective resilience measures. For large portfolios, companies should screen assets, prioritize strategically important high-risk properties and target investment accordingly. Resilience can reduce repair costs, business interruption, and recovery time, while supporting insurance, financing, and asset value decisions. The key message: climate data becomes valuable only when it leads to practical action at the asset level.

Wayne Visser discusses how companies can distinguish genuinely transformative climate technologies from hype. He argues that promising solutions should combine meaningful environmental impact with evidence of falling costs, improving performance, and growing adoption. Solar, wind, batteries, EVs, and Earth information systems are already relatively mature, while green hydrogen, low-carbon cement, bioplastics, cultivated meat, and other emerging technologies still face cost or scaling barriers. AI and robotics can create significant value when applied to physical systems such as agriculture, recycling, monitoring, and logistics. Visser emphasizes that every technology has trade-offs, so businesses should assess lifecycle impacts, infrastructure, economics, and real-world results. His advice is to experiment through pilots and partnerships, invest early where technology could transform the core business, and avoid chasing trends without evidence.

Frédéric Pouyot, founder of GPEKS, explains why net-zero infrastructure requires systems thinking rather than isolated solutions. Drawing on more than two decades of experience, he argues that buildings, energy, finance, mobility, and communities must be planned together to deliver lasting environmental and economic value. The conversation explores how better design can reduce energy demand before technologies such as solar panels or heat pumps are added, and why investments should be assessed using life-cycle costs rather than upfront price alone. Pouyot also discusses resilient and affordable housing, renewable energy integration, Indigenous and community participation, workforce development, and the need to break down professional silos. His central message is that the transition to net zero depends not only on cleaner technologies, but on connecting people, planning, finance, and infrastructure into adaptable systems designed to perform for generations.

In this Net Zero Compare podcast, Karol Kaczmarek speaks with Manuj Aggarwal, founder and Chief Innovation Officer of TetraNoodle Technologies, about the practical role of artificial intelligence in sustainability. The discussion explores how AI can support emissions reduction, ESG reporting, supply-chain oversight, resource efficiency, predictive maintenance, and operational decision-making. Aggarwal stresses that companies should begin with a clearly defined business problem rather than the technology itself. Reliable data, strong governance, privacy controls, measurable outcomes, and human oversight are essential, particularly when AI is used for compliance or public disclosures. The episode also examines private AI systems, digital traceability, the environmental footprint of AI, and the reasons many pilot projects fail to reach full implementation. The key message is that AI can improve sustainability performance, but it cannot compensate for poor data, weak processes, or unclear accountability.

Sustainability strategy now extends beyond emissions reporting and ESG compliance to include supply chain resilience, energy security, trade policy, critical minerals, and geopolitical risk. Dr. Anita Renda Kellogg explains that clean-energy technologies often depend on highly concentrated mineral-processing networks, creating exposure to trade disputes, export restrictions, and supply disruptions. Companies should map suppliers beyond Tier One, reassess just-in-time models, diversify sourcing, consider friend-shoring, and weigh resilience alongside purchase price. ESG, procurement, finance, legal, and strategy teams should share a common risk view, as poor data and limited supplier visibility can undermine both carbon accounting and business continuity. The central message is that credible decarbonization plans must account for access to materials, suppliers, and infrastructure, as well as stable policy, in an increasingly uncertain world.

Credible reforestation is not just about planting large numbers of trees. In this Net Zero Compare podcast, Hank Dearden, Founder and Executive Director of ForestPlanet, explains that successful projects depend on local expertise, healthy nurseries, appropriate species selection, community incentives, and realistic reporting. ForestPlanet funds experienced local planting partners rather than operating as a formal carbon-credit developer. Dearden stresses that companies should understand what they are funding, what evidence they will receive, and what claims they can responsibly make. Tree planting can support biodiversity, livelihoods, coastal protection, and climate goals, but it should not be treated as a verified carbon offset unless proper carbon-credit methodologies, monitoring, and verification are in place. The key message is that reforestation can be valuable, but credibility depends on project design, transparency, and long-term survival.

Tom Raftery argues that sustainability is becoming part of everyday business management, linked to cost, risk, resilience, and efficiency. Clean energy is increasingly an economic decision, helping companies reduce exposure to volatile fossil fuel prices and improve energy security. Supply chain visibility is essential for measuring emissions, managing risk, and improving procurement decisions. Scope 3 reporting requires supplier cooperation, starting with the suppliers responsible for the largest share of emissions. AI can support complex supplier analysis, but only when companies have reliable data. The main message: start by measuring emissions, engage priority suppliers, and integrate environmental data into financial and operational systems.

Helen Neal, founder of HN Communications and creator of Zena, explains why sustainability communication has become a governance issue, not just a marketing task. She argues that greenwashing often results from weak internal processes rather than intentional deception, especially when sustainability, legal, marketing, and corporate affairs teams work separately. The discussion covers how companies can reduce risk by defining claim scope, keeping evidence, clarifying methodologies, involving teams earlier, and reviewing content before publication. Neal also highlights greenhushing, where companies avoid communicating legitimate progress due to fear of criticism. The podcast emphasizes that credible sustainability communication should be accurate, evidence-based, transparent about limitations, and adapted to different regulatory markets.
