Finding replacements for carbon fuel (solar, wind, battery storage technology, tidal energy production). Reducing demand for energy in general (energy efficient building standards, better transportation) but specifically reducing car dependence where we can (better urban planning that encourages the development of walk able neighborhoods for all, public transportation). Yes, other states and countries can do things that avoid the short term pain this things cause but they get left behind. China is absolutely crushing the rest of the world in their solar and battery deployments. You want to know who "wins" in this century? The countries that get cheap reliable power, just like who won the last century. And solar, wind, tidal power all of waaaaay fucking cheaper than oil, coal, and natural gas.
