2026: the year your climate resolutions finally stick
Every start of the year, millions of French people make resolutions — lose weight, read more, travel more. In 2026, one resolution stands out with particular urgency: reducing your carbon footprint. But like any resolution, intention alone is not enough. What you need is a concrete, progressive, and realistic action plan that fits into your daily life without asking you to change everything overnight.
Here is your monthly roadmap for 2026.
Start by measuring: you can't reduce what you don't know
Before setting goals, you need to know your starting point. A French person emits an average of 8.9 tonnes of CO2 equivalent per year. But this average masks very different realities depending on lifestyle, geographic location, housing, and consumption habits.
Calculate your personal carbon footprint before January 31. Recommended tools: ADEME's simulator (nosgestesclimat.fr), the Carbone 4 calculator, or the OFFSET app which uses your banking data for an estimate based on your actual spending. For a detailed method, check out our guide on how to calculate your personal carbon footprint.
January-February: housing — the biggest savings potential
Housing accounts for an average of 25% of the carbon footprint of French households. It is also the sector where quick actions have the greatest impact.
- Lower your thermostat by one degree: going from 20°C to 19°C reduces your heating consumption by 7%. Below 19°C, the effort is harder but the savings continue to grow.
- Descale your radiators: 1 mm of limescale increases consumption by 7%. A properly bled radiator heats better and consumes less.
- Install weatherstripping on doors and windows: heat loss through poorly sealed joints often accounts for 10 to 15% of heat loss.
- Request an energy audit: if you're a homeowner, a DPE energy audit will help identify priority work and available subsidies (MaPrimeRenov').
Monthly goal: reduce home energy consumption by 10% in January-February.
March-April: mobility — rethinking your daily commute
Transportation accounts for approximately 30% of the average individual carbon footprint in France. It is the second major lever.
- Map out your recurring trips: work, errands, leisure activities. For which ones are cycling, public transit, or carpooling viable options?
- Try public transit for a month: many French people underestimate the quality of local networks simply because they don't know them. A one-month trial lets you judge with full knowledge.
- Adopt eco-driving if you still need to drive: anticipation, steady speed, gradual deceleration. Estimated savings: 15 to 20% on fuel.
- Consider carpooling for your commute: apps like Karos, Klaxit, or BlaBlaCar Daily help you find ride partners.
Monthly goal: reduce solo driving by at least 20%.
May-June: food — eating better, not less
Food accounts for approximately 25% of the individual carbon footprint. Good news: dietary changes are among the most impactful and most financially accessible.
- Cut red meat down to once a week: beef emits 25 to 30 kg of CO2 per kg produced. Replacing one beef meal with a vegetarian one per week reduces your food footprint by 8 to 10%.
- Join a CSA or local farm delivery service: buying local and seasonal reduces transportation emissions and supports committed farmers.
- Reduce food waste: 30% of food produced is wasted. In France, each person throws away an average of 29 kg of food per year. A well-used freezer, a strict shopping list, and meal planning work wonders.
- Plan seasonal menus: an out-of-season tomato grown in a heated greenhouse emits 8 times more CO2 than a field-grown tomato in July.
Monthly goal: reach 4 days per week without red meat by the end of June.
July-August: vacation — traveling without blowing your carbon budget
Summer vacations are often the biggest carbon category of the year for households that travel. A round-trip flight from Paris to New York emits more than 3 tonnes of CO2 per passenger — that's 30 to 50% of the annual target for 2050.
- Choose a destination reachable by train: all of Europe is accessible from Paris in under 24 hours by rail — and the journey is part of the adventure.
- If you fly, offset your emissions through a certified project and reduce your other summer emissions (less driving, more plant-based food).
- Stay in France: French regions offer exceptional diversity — sea, mountains, countryside, heritage — without any flight-related emissions.
Monthly goal: plan at least one week of vacation without flying.
September-October: consumption — buying less and better
The back-to-school season invites impulse purchases: clothes, supplies, electronics. This is the time to put new consumption rules in place.
- The 30-day rule: wait 30 days before any non-essential purchase. Often, the desire passes.
- Buy refurbished or second-hand electronics: a refurbished smartphone costs 40 to 60% less and emits 80% less CO2.
- Repair before replacing: the anti-waste law requires a repairability index on electronic devices. Use it.
- Rent instead of buy for seldom-used equipment: power drills, bikes, camping tents...
November-December: automate and sustain your actions
The last two months of the year are decisive for anchoring the habits built throughout the year. It's also the period most prone to overconsumption (Black Friday, Christmas).
- Automate your carbon offsetting: set up a monthly automatic transfer to a certified project — or use an app like OFFSET that does it with every purchase.
- Do your year-end review: recalculate your carbon footprint in December and compare it to January. Even a 10 to 15% reduction is a significant victory.
- Keep Black Friday at arm's length: if you need to buy gifts, favor local artisans, durable products, and second-hand goods.
"The best resolutions are not the ones you make in January. They're the ones that survive in June. The key: make them easy, automatic, and enjoyable."
— BJ Fogg, behavioral science researcher, Stanford
Your 2026 dashboard
To stay on track, here are the indicators to monitor throughout the year:
- Estimated carbon footprint (recalculate quarterly).
- Kilometers driven alone (vs. carpooling + public transit).
- Number of days per week without red meat.
- Share of second-hand or refurbished purchases in total consumption.
- Amount offset through certified carbon projects.

2026 can be your carbon year. Not because you'll have changed everything overnight, but because you'll have started — truly started — to change over the long term. That's how the climate battle is won: one action, one month, one resolution at a time.
