The Most Impactful Things You Can Do for the Climate Aren’t What You’ve Been Told

New WRI research shows that pro-climate behavior changes, such as driving less or eating less meat, could theoretically cancel out all the greenhouse gas (GHG) emissions an average person produces each year1 — specifically among high-income, high-emitting populations.

But it also reveals that efforts focused exclusively on changing behaviors, and not the overarching systems around them, only achieve about one-tenth of this emissions-reduction potential. The remaining 90% stays locked away, dependent on governments, businesses and our own collective action to make sustainable choices more accessible for everyone. (Case in point: It’s much easier to go carless if your city has good public transit.)
