Climate Rising

Marcelo Medeiros, co-founder and CEO of re.green, joins Climate Rising to discuss how his company is restoring millions of hectares of degraded land in Brazil’s Atlantic Forest and Amazon biomes by producing high-quality nature-based carbon removal credits. Marcelo explains how re.green combines data science, forest restoration, and long-term land ownership to deliver durable carbon sequestration—and why they chose a for-profit model to scale impact. He discusses price transparency, quality verification, and how re.green is preparing for a future where compliance carbon markets may accept removal-based offsets from nature-based solutions. Marcelo also shares how winning the Earthshot Prize brought global visibility, how AI is improving ecosystem planning, and how the company works with clients like Microsoft and Telefónica under long-term offtake agreements.

As bonus episode of Climate Rising, we feature a conversation among Tata Power CEO Dr. Praveer Sinha, Harvard Business School Professor Vikram Gandhi, and HBS Chief Marketing and Communications Officer Brian Kenny  that explores how India’s largest private power company is navigating its net-zero commitment while supporting a rapidly growing economy. With energy demand projected to quadruple by 2047, Tata Power has committed to phasing down coal and expanding renewables, distributed generation, and smart grid investments. This conversation, based on the HBS case “Tata Power and India’s Energy Transition” and originally recorded for the HBS Cold Call podcast, explores how Tata Power balances profitability and purpose, the role of technology and grid modernization, and how energy transition in the Global South differs from the Global North. Dr. Sinha also shares insights on employee reskilling, engaging customers as “prosumers,” and why long-term vision is critical to executing a climate-aligned business strategy. This episode is part of Climate Rising’s Global South series, which features companies and organizations at the intersection of business and climate in India and Brazil.

Parth Jindal and Prabodha Acharya of JSW Group join Climate Rising to discuss how one of India’s largest industrial conglomerates is reducing the carbon intensity of its steel business while scaling infrastructure for a fast-growing economy. They share how JSW built vertically integrated operations—from power to cement to ports—through industrial symbiosis, and why energy efficiency, renewable power, and circular practices are at the heart of its decarbonization roadmap. The conversation explores India’s dual challenge: meeting rising domestic steel demand while managing its climate vulnerability. Parth and Prabodha explain JSW’s green investments, hydrogen pilots, carbon capture initiatives, and why cost competitiveness, stakeholder pressure, and industrial policy shape the path forward. This is part of our Global South series, which also features Tata Power and organizations in Brazil at the intersection of business and climate. Explore more episodes at climaterising.org.

Galen Nelson, Chief Climate Officer at the Massachusetts Clean Energy Center (MassCEC) explains how the state is helping accelerate climate innovation through early-stage grants, equity investments, and infrastructure support. Galen outlines how MassCEC targets “market failures” where private investors hesitate—such as pilot and demonstration projects—and how these public investments help attract follow-on capital, inform policy, and build economic resilience. Galen shares examples across climate tech verticals including energy efficiency, carbon-intensive materials like cement, and urban heat resilience. He also discusses how MassCEC is responding to the shifting federal policy landscape, its new authority to fund climate adaptation technologies, and how the agency’s public-private model balances innovation with accountability.

Jonathan Schrag, Deputy Climate Chief for the Commonwealth of Massachusetts, joins Climate Rising to discuss how the state is tackling emissions, electrifying infrastructure, and responding to a shifting federal policy landscape. Jonathan shares how Massachusetts’ newly created Climate Office coordinates across agencies—from housing to public health to corrections—to embed climate action into all corners of state government. He discusses the state’s emissions targets, the role of local municipalities in building codes and EV infrastructure, and the growing headwinds from federal rollbacks, tariffs, and canceled clean energy grants. He also reflects on market uncertainty, offshore wind, geothermal pilots, and the promise of small modular nuclear reactors.
