If you teach English, you already know the subject is secretly a life skills course in disguise. You don’t just teach grammar and essays; you teach students how to notice, question, empathize, argue, imagine and make meaning. That’s exactly why English is one of the most natural places to weave in sustainability.

Green education doesn’t have to mean swapping your entire curriculum for climate documentaries or forcing every creative writing prompt to involve melting ice caps. It can be quieter (and often more powerful): selecting texts with environmental angles, inviting students to think critically about the language used in climate communication, and encouraging them to write for real audiences and with real-world stakes.

Below are ways to integrate sustainability into English lessons while still meeting literacy goals, plus a note on using AI consciously – because even our digital tools come with an environmental footprint.

1. Start with “green reading”: texts that open doors, not close them

The simplest entry point is text selection. Sustainability themes appear across genres and time periods, and you can choose materials that fit your students’ maturity level and your existing curriculum goals.

Ideas to try:

• Short stories that explore human-nature relationships, scarcity, or future societies shaped by environmental change.
• Poetry that foregrounds place, seasons, biodiversity or loss. Nature poetry is an easy bridge into imagery, tone and figurative language.
• Nonfiction articles on fast fashion, food waste, wildfires, local conservation projects or “greenwashing” in advertising.
• Speeches and opinion pieces that let students analyze rhetoric, claims, evidence, emotional appeals and bias.

A useful approach is to build a “paired text” routine: pair a literary text with a current nonfiction piece. Students can practice comparative analysis while also seeing how themes evolve from art into public discourse.

2. Teach language as power: sustainability is a rhetoric unit waiting to happen

Sustainability conversations are full of persuasive language, sometimes honest, sometimes manipulative. That makes them perfect material for rhetoric and media literacy.

Mini-lessons you can try:

• Greenwashing detective work: bring in ads or brand sustainability statements. Ask: What claims are being made? What evidence is offered? What’s vague? What’s measurable?
• Framing and connotation: compare “climate change” vs. “climate crisis,” “carbon-neutral” vs. “net zero,” “natural” vs. “organic.” What do these terms imply and who benefits?
• Tone analysis: how do different outlets report the same environmental story? Neutral? Alarmist? Dismissive? Hopeful? Students can annotate for diction and bias.

This helps students become more thoughtful readers and more ethical communicators, two outcomes worth aiming for even when the topic isn’t sustainability.

3. Make writing real: sustainability projects with authentic audiences

When students feel their writing has a purpose beyond “hand it in, get a grade”, quality and investment usually rise. Sustainability offers plenty of authentic writing opportunities, even at a small scale.

Writing tasks that work well:

• Letters or emails to the school administration proposing a realistic change (recycling signage, reducing single-use plastics at events, a second-hand uniform swap).
• Op-eds for the school newsletter on an issue students care about (food waste in the cafeteria, bus vs. car drop-offs, energy use).
• Instructional writing: “How to…” guides for greener habits (thrifting, repairing clothes, reducing digital clutter).
• Podcast scripts or short documentary-style narration about a local environmental story.

The trick is to keep the scope manageable. Sustainability writing doesn’t need to save the planet; it needs to strengthen students’ ability to argue clearly, use credible evidence and write with voice.

4. Use storytelling to build empathy and avoid burnout

Many students feel overwhelmed by environmental news. English teachers are well placed to counter “doom fatigue” by using narrative, especially stories that hold complexity.

Try prompts that balance realism with agency:

• Write a scene where a character makes a small decision that has ripple effects.
• Create a “future news report” set 20 years from now, showing both challenges and adaptations.
• Write from a non-human perspective (a river, an old tree, an urban fox) to practice voice and point of view.

The goal isn’t to sugarcoat realities, but to make room for imagination and nuance: people can be contradictory; systems shape choices; hope can be practical, not sentimental.

5. Build sustainability into routine classroom habits (so it’s not just a topic)

Sometimes, green education is less about what you teach and more about how the classroom runs.

Small changes can become teachable moments:

• Encourage digital submissions only when they truly help, and be mindful of unnecessary printing (but also avoid assuming digital is “free”; more on that below).
• Reuse materials. Create a “paper bank” for scrap writing and drafting.
• Do a short “language + environment” warm-up once a week: a new word (like “circular economy” or “biodiversity”) used in a sentence, then discussed for nuance.

When sustainability becomes the norm rather than a special unit, students absorb it as part of everyday thinking.

6. A necessary addition: conscious use of AI (because it has an environmental cost)

AI can be a helpful classroom tool, especially for brainstorming, drafting models, generating sentence stems or supporting students who struggle to start. But it’s worth naming what often stays invisible: AI requires energy. Data centers, model training and even repeated daily queries contribute to electricity and water use, depending on how systems are cooled and powered.

That doesn’t mean “never use AI”. It means modelling the same critical thinking we want students to use everywhere else: use it with intention.

Practical guidelines for greener, more ethical AI use:

• Use AI when it replaces a bigger footprint. For example, generating one strong mentor text instead of printing five random worksheets.
• Batch tasks. One well-planned prompt is better than ten quick “try again” prompts.
• Teach prompt discipline. Have students plan what they want first, then query once. This improves learning and reduces unnecessary use.
• Be transparent. Treat AI like a tool with trade-offs: useful, imperfect and not environmentally neutral.
• Prioritize human thinking. AI should support reading and writing, not replace the process that actually builds skill.

Framing AI this way turns it into another sustainability lesson: every choice. digital or physical, has a cost, and responsible people learn to weigh trade-offs.

English is where sustainability becomes personal

Sustainability isn’t only a science topic; it’s a human story. It’s about values, choices, culture, language, power and the way we imagine the future. English teachers already teach students how to read between lines and write with purpose. Integrating eco-conscious tasks simply gives those skills somewhere urgent and real to land.

Start small: a poem, a paired article, a writing task with an authentic audience, a quick discussion about greenwashing, a mindful approach to AI. Over time, your classroom can become a place where students don’t just learn English, they learn how to speak for the world they’re growing up in.

In Part 1, we looked at how to build a sensible measurement philosophy for language training using KPIs and the Global Scale of English (GSE). We’ve established that language programs shouldn’t be treated as a calendar entry, but as a strategic lever, and that independence, granularity and credibility are the secret sauce.

Now it’s time to move from how to why: how these datapoints translate into tangible business outcomes, and how to make sure your investment in English doesn’t just look good on slides but actually delivers value when the CFO walks in.

From measuring to meaning: translating KPIs into ROI

Let’s be blunt: only a reckless stakeholder invests without expecting a return. Weighing costs and benefits, however, can get tricky. Without some operational clarity, ROI quickly becomes either a fairy tale or a labyrinth, both of which are bad news in risk-averse corporate cultures.

From a client’s perspective, it’s vital to include all components in your calculation: direct delivery fees, platform access, materials and, ideally, a provider capable of offering the full package. And please don’t forget the indirect cost of time. Two hours of lessons per week equals more than 100 hours per learner per year. Add the asynchronous learning that every serious learner contributes, and we’re suddenly talking about real numbers.

If you skip that, the ROI will look spectacular on paper until someone performs a reality check and the budget line gets a little uncomfortable. If you’re an L&D manager reading this, add sensible estimates for coordination and reporting. Ideally, your provider helps you keep those to a minimum. At choices®, which provides language services, we see this as part of the service rather than a side quest. Trust me, it saves everyone time and sanity.

It’s that time of year again. Students are heading off on their winter breaks to spend time with their friends and family. It’s the perfect time to think about what we can do to keep our students motivated to practice their English during the break.

Reading is a great way for students to expand their vocabulary and improve their language skills from the comfort of their sofas. The problem learners often have, however, is finding a book that is both suitable for their level and entertaining enough to hold their attention.

Here are three festive readers that you can recommend to your students to keep them busy this holiday season. We have also included downloadable teaching notes and audio samples so you can introduce them in your classes and get an idea of how these could be used as teaching materials.
