Present the data, argue the policy, and make the case for the planet — out loud.
First, the word choice that marks your region: sostenible and sustentable mean the same thing, and Mexico leans sustentable while both alternate in Colombia. In activist circles el cambio climático shrinks to el CC, and Mexicans call el calentamiento global simply el calentón in protests and on social media. The policy vocabulary has colloquial doubles too: el impuesto al carbono becomes el impuesto verde in Colombia and Chile, regulation without enforcement gets dismissed as es papel mojado, and the standard reproach against corporate eco-marketing is puro greenwashing.
Below: the sustainability, policy and activism vocabulary lesson by lesson, how real activists actually say it, and a way to learn it with no flashcards — every term used out loud in a live debate.

Olivia
Your vocabulary teacher for this pack
Nothing to memorize, nothing to fill in — in the Eco Activist lessons you make the argument, and Olivia supplies each term the moment your case needs it. One lesson you're on a climate summit panel, presenting las emisiones de CO2 and proposing policy measures. Another is a community activism meeting, where technical talk won't land and you have to advocate in plain, persuasive Spanish — crear conciencia, not lecture. Then an environmental impact assessment, walking stakeholders through la evaluación de impacto ambiental and what mitigation actually looks like. Out loud, with Olivia challenging the weak points.
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.
Quick answers
Both — they mean the same thing. Sustentable is the more common choice in Mexico, and Mexico and Colombia alternate freely between the two. You'll also hear the noun form: apostar por lo sostenible.
La huella de carbono. In eco conversations in Colombia and Peru it's often just la huella — the carbon part is understood. The wider concept is la huella ecológica.
El impuesto al carbono — colloquially el impuesto verde in Colombia and Chile. And when environmental law exists but nothing gets enforced, the standing complaint is es papel mojado.
Formally it's la protesta pacífica, but everyone says la marcha — nos vemos en la marcha por el clima. In Argentina young activists get the affectionate label los pibes ambientalistas, and raising awareness is crear conciencia rather than the stiff la concienciación.
El calentamiento global is the temperature rise; el cambio climático is the whole system shift it drives — advanced Spanish keeps them distinct, just like el reciclaje versus reuse. Colloquially Mexicans compress the first to el calentón.
