English Environment & Climate Vocabulary

By the end of this page you can…

…talk about the natural world, describe climate change and extreme weather, discuss energy and pollution, and say what people do to protect the planet.

How this list was chosen

Every word here comes from the English frequency list (hermitdave/FrequencyWords), which ranks words by how often they appear in a large collection of everyday subtitles. From that list we kept the environment and climate words a B2 learner needs and grouped them by theme rather than by rank. The Rank column is the word’s real position in the list — a lower number means the word is more common. Several key topic words (such as renewable and sustainable) sit low on the list but are essential here, so they stay in.
