Sweeping political changes are nothing new. While the recent U.S. elections pose challenges for climate progress, we must not waver. Now is the time to double down on efforts to zero out emissions. Here’s what’s top of mind for us at Speed & Scale: 🧵

KNOW WHICH WAY THE WIND BLOWS 🌬️ The Trump administration has frozen 150+ proposed onshore wind farms. Meanwhile, China installed 3x as much wind power capacity as the rest of the world combined in 2025. More in our latest newsletter 🔗https://t.co/8GGjlLJl5B

A “coalition of the willing” from 57 countries met in Colombia in April to chart a path toward global decarbonization, without fossil fuel interests in the room. The goal: move past stalled consensus and build momentum for a fossil-free future.

Money is a critical enabler—and constraint—of the energy transition.

Even as clean energy investment grows, public energy R&D has fallen to about $53B in 2025.

Thanks to renewables, the world avoided $467B in fossil fuel spending in 2024. Cost curves are moving—but not everywhere.

Progress now depends on pushing advantages in cost into harder-to-abate sectors.

Climate progress isn’t just about tech—it’s about people and the pressure they bring to bear. And momentum is building.

4/5 people want their governments to take stronger climate action.

Climate solutions don’t implement themselves—and the gap between ambition & action is striking.

Even if all current pledges were met, the world would still be headed for 2.3–2.5°C of warming.

Cutting emissions isn’t enough. We also need carbon removal at scale.

Progress so far is limited. Despite more than $2 billion of investment, barely a thousand tons of CO2 have been removed.

We’ve revamped the Speed & Scale Climate Tracker to improve our measurement of real-world progress toward net zero.

The data shows momentum is building, but not fast enough. Emissions are still rising, and progress is uneven.

Steel, cement, and chemicals power the global economy, but they also drive a major share of global emissions.

Protecting nature is one of the fastest ways to cut emissions—and this Earth Day is a reminder of what’s at stake.

The world lost nearly 30M hectares of forest in 2024. We’ve got to turn this around.

Fixing food means changing how we grow, move, & consume food.

In the US, food waste totaled 70M tons in 2024, barely down from 71M tons in 2016. New solutions are emerging, but the challenge is to scale them.

Not all parts of the grid are moving forward together.

Solar + wind are accelerating, storage is lagging, 24/7 clean power isn’t scaling fast enough, and methane + fossil fuels are at code red.

EVs now account for 1 in 4 new car sales globally. Cars are on track—but trucks, buses, aviation, and shipping are lagging or failing in our updated Tracker.
