CO2gether: The Latest Updates

Bicycles are widely recognized as one of the most environmentally friendly forms of transportation. However, taking a closer look at the manufacturing process and material waste left behind reveals that bicycles are not entirely free from environmental impacts. Bicycles' environmental cost begins to accumulate from their manufacturing stage. Aluminum is the most common material used in bicycle frames, which requires a highly energy-intensive manufacturing process. Producing o

Nearly 20,000 people can gather in one building for just three hours, yet the largest source of greenhouse gas emissions associated with the event never existed within the building at all. This is an odd reality of professional basketball games: the most environmentally costly component of an NBA game is not the dazzling scoreboard, the colorful lights of the arena, or even the players’ flights in luxury private jets. It is the crowd’s transport to and from the avenue that ad

The first Earth Day on April 22, 1970 drew twenty million Americans into the streets, a scale of unified environmental action that feels almost unimaginable in today's polarized landscape of climate discussions. In this interview, Tia Nelson, daughter of Earth Day's founder Senator Gaylord Nelson, discussed the personal lessons she carries from her father's legacy and what it takes to rebuild the same kind of broad, bi-partisan climate action that defined the early Earth Day

Solar power has become the foundation of the global clean energy transition, but some of its most promising innovations are being developed far beyond Earth. At the Korea Advanced Institute of Science and Technology (KAIST), there is ongoing research to design perovskite solar cells to withstand the extreme temperature fluctuations of space, where durability is as critical as efficiency. In this interview, Lee Seung-min, a solar cells researcher at the KAIST Department of Mat

Environmental responsibility is no longer viewed solely as a corporate commitment, but is increasingly becoming an important factor in long-term business strategy and investment decisions. In the logistics industry, where transportation accounts for a significant share of emissions, companies are under growing pressure to improve efficiency while reducing their environmental impact. In this interview, Yoo Hyun-chul, Investor Relations Manager at CJ Korea Express, discusses ho

As investors, regulators, and businesses gradually recognize climate risk as a driver of corporate performance, sustainable finance has emerged as a central force in the transition to a net-zero economy. In this interview, Kang Chang-mo, an Associate Professor of Finance at the Hanyang University School of Business, shared how climate risk influences corporate value, why financial markets play a critical role in driving sustainability, and what policies are needed to encourag

The transition to cleaner energy depends not only on renewable power and batteries, but also on the innovations that make energy systems more efficient, namely cooling technologies. Refrigerants and thermal management solutions are one way to reduce energy consumption in electric vehicles. In this interview, Cho Dong-seop shared insights into the growing demand for advanced thermal management solutions and how innovations in cooling technologies could contribute to a more sus

As the demand for clean energy and emerging technologies continues to grow, batteries are becoming the foundation of electric vehicles and artificial intelligence infrastructure. In this interview, Lee Seung-jun, Media Relations Manager at Samsung SDI, discussed the company's next-generation battery technologies, efforts to build a more sustainable battery lifecycle, and how innovations such as energy storage systems are shaping the future of the energy transition. First, cou

Financial institutions are playing an increasingly important role in accelerating the transition to a low-carbon economy by directing capital toward sustainable industries. In this interview, Lee Eun-ha at the Shinhan Financial Group's SDGs Planning Team discussed the importance of climate-related financial disclosures, the need for sustainable finance strategies, and how financial institutions can support businesses in balancing economic growth with decarbonization. First, c

Brazil already runs cars on pure ethanol, and countries like the Philippines and Vietnam blend it into gasoline to cut sulfur emissions. However, in Korea, low-carbon fuel has barely entered the domestic market. In this interview, Kim Sun-wook of the Korea Alcohol Group discussed how the company sources and exports fuel ethanol across Asia, why unclear government policy remains the biggest obstacle to adopting it domestically, and the natural limits like arable land that keep

EVs are increasingly becoming an important part of the global transition to net-zero, and public understanding of battery technology has become just as important as technological innovation itself. Beyond developing safer and more sustainable batteries, companies must also communicate their environmental impact transparently while addressing public concerns about safety, affordability, and sustainability. In this interview, Choi Ki-bong, PR Team Leader at SK On, shared how st

As the global energy transition accelerates, geophysics is playing an increasingly important role beyond traditional oil and gas exploration, supporting emerging technologies such as carbon capture and storage (CCS). In this interview, Lim Bo-sung, a senior geophysicist at TotalEnergies, discussed how geophysical techniques are used to identify and monitor CO2 storage sites and how new seismic survey methods are cutting the carbon footprint of exploration. First, could you te
