Fifteen years ago, when the reality of climate change began to sink in, it became clear that avoiding a climate disaster would be an unprecedented challenge. The solution seemed to lie in aggressive investments in clean-energy innovation and deployment. Today, we have made significant progress, but the task ahead remains daunting. Annual greenhouse gas emissions continue to rise, pushing us further away from limiting global temperature rise to safe levels. Clean technologies are not yet practical or cost-effective enough to be deployed at scale. To overcome these challenges, we must embark on the largest crisis response in human history.

The Complexity of the Energy Transition: The 51 billion tons of annual greenhouse gas emissions come from nearly every aspect of human activity. While progress has been made in the electricity sector, accounting for only 26 percent of global emissions, other sectors like transportation, agriculture, buildings, and manufacturing still pose significant challenges. The dependence on emissions-intensive processes in manufacturing, such as cement, plastic, and steel production, further complicates the transition to cleaner alternatives. Moreover, addressing climate change requires a global effort, as emerging economies now account for a significant share of total greenhouse gas emissions.

The Three-fold Solution: Addressing the “everything, everywhere” challenge necessitates a three-fold approach. First, we must invent clean technologies to replace emissions-intensive processes in various sectors, from steel production to long-distance travel. Second, the cost of these technologies must be driven down to compete globally, ensuring they are accessible in all countries. The reduction of the “Green Premium” (the price difference between current technologies and clean alternatives) is crucial for widespread adoption. Third, we must deploy these cost-competitive technologies rapidly, replacing existing infrastructure dedicated to old methods with infrastructure aligned with the new clean paradigm.

Progress and Challenges: Over the past decade, both public and private investments in climate-related research and development (R&D) have increased significantly. Climate-focused venture capital funds and clean-energy start-ups have witnessed substantial investments, fostering innovation and creating a diverse pipeline of technologies. Established companies have also shifted their investments and expertise toward net-zero commitments. Public policies have become more ambitious, with governments passing laws and enacting targets to support the energy transition. However, challenges remain, including geopolitical tensions, investment in new fossil fuel projects, and the need for inclusive, just transitions for communities affected by the shift.

The Path Forward: To navigate the path to net zero, three key actions must be taken. First, continued investment in research, development, and demonstration is essential to make clean technologies more competitive. Sustainable liquid fuels, CO2 capture methods, and additional renewable energy sources require significant attention. Second, a fair and workable process for scaling up clean technologies must be established, considering the potential disruptions and ensuring a just transition for affected communities. Balancing responsible tradeoffs and engaging with communities will be crucial. Finally, investments in adaptation measures are necessary to help communities cope with the already-changing climate.

Measuring Success: While the ultimate measure of success is achieving zero greenhouse gas emissions, interim success can be gauged by reducing Green Premiums. By 2040, Green Premiums need to approach or reach zero for a wide range of products and processes. This will facilitate the scaling up of clean technologies and indicate progress towards a sustainable future. Europe and the United States, as historically significant emitters, have a responsibility to eliminate their emissions and invest aggressively to drive down Green Premiums. This will enable other countries to reduce their emissions while achieving economic growth and an improved standard of living.

Key Takeaways: The challenge posed by climate change is unparalleled, but humanity has proven its ability to mobilize in times of crisis. With the right investments, policies, and collective efforts, we can avert.
