30 Green New Year’s Resolutions for a More Eco-Friendly Life

New Year’s resolutions are a well-established tradition, yet few of us follow through. The United Nations Environment Programme (UNEP) and the IPCC both identify demand-side changes in diet, transport and housing as a significant part of the emissions reductions needed. Individual choices are not a substitute for policy, but they add up and they influence markets and neighbours.

Why do environmental resolutions matter?

Because environment and health are linked. The World Health Organization (WHO) estimated that unhealthy environments caused about 12.6 million deaths in 2016, roughly one in four of all deaths. Vague resolutions produce vague results, so every resolution below comes with a specific action you can take this week.

30 Green New Year’s Resolutions

Food and diet

1. Cut red meat to two meals per week or fewer. Poore and Nemecek (2018) estimate that beef from beef herds emits about 50 kg CO2e per 100 g of protein, against about 0.4 kg for peas. Swapping a few beef meals a week for legumes cuts your food footprint noticeably.
2. Weigh your food waste for two weeks in January, then cut it by half. Eurostat reports that EU households generate roughly 70 kg of food waste per person per year. Identify your three most-wasted items and target them with a meal plan and proper storage.
3. Switch your daily coffee or tea to oat, soy or almond milk. Poore and Nemecek (2018) estimate about 3.2 kg CO2e per litre for cow’s milk and about 0.9 kg for oat milk, a cut of around 70% for each serving.
4. Set up a home compost system by the end of January. A kitchen caddy with a weekly transfer to an outdoor bin or a Bokashi fermenter keeps food scraps out of landfill. In Germany, municipalities must offer organic waste collection (Biotonne), so use it for every food scrap.
5. Shop at a package-free or refill store once a month. Bring jars and bags for staples such as pasta, rice, legumes, nuts and spices. Such stores exist in many cities in Germany, the UK and Canada.

Transport and travel

6. Replace one return flight this year with a train journey. The EEA’s figures show rail at roughly 14 g CO2e per passenger-kilometre against roughly 285 g for domestic flights, so the saving can be large. Check a carbon calculator for your specific route before booking.
7. Walk or cycle every journey under 3 km for one month. Roughly half of all car trips in Germany cover less than about 5 to 6 km, according to the Federal Environment Agency (Umweltbundesamt). Commit to car-free short trips for January and track the habit.
8. Switch off your car engine when you stop for more than a minute. Idling burns fuel with no benefit, so turn the engine off at rail crossings, in car parks and at school pick-ups.
9. Carpool for at least one regular journey per week. Coordinate with a neighbour, colleague or school parent for one fixed weekly trip, which halves the per-person emissions and fuel cost of that trip.
10. Use a public transport app for two journeys a week that you would otherwise drive. In Germany try DB Navigator or your local operator’s app, and check the Deutschlandticket if you commute. In the UK try Citymapper, and in Canada try Moovit or Transit.

Home energy

11. Get a home energy audit in the first quarter and act on the top recommendation. In Germany, the Verbraucherzentrale offers subsidised energy advice. In the UK, the Energy Saving Trust provides guidance, and in the US the Department of Energy’s Home Energy Score helps. Draughts and poor insulation are common culprits.
12. Switch to a renewable electricity tariff by the end of February. German examples include Naturstrom, Greenpeace Energy and EWS Schönau, and UK examples include Octopus Energy and Ecotricity. Check that the tariff is certified and adds new renewable capacity, because tariffs differ in quality. These examples are not endorsements.
13. Enable power-saving mode and cut standby use. The IEA estimates that standby power accounts for a noticeable share of household electricity, often put at 5 to 10%. Switchable power strips and sleep settings cost almost nothing.
14. Replace your five most-used bulbs with LEDs if you have not already. The US Department of Energy says LEDs use at least 75% less energy than incandescent bulbs and last much longer, so payback is usually quick.
15. Lower your thermostat by 1°C and add a layer. A commonly cited rule is that each degree lowers heating energy by roughly 6%, though the exact saving depends on your home and climate.

Plastics and waste

16. Carry a reusable water bottle and coffee cup every day. They replace hundreds of single-use items a year. Buy once and use for years.
17. Run a one-week plastic audit. Count every single-use plastic item you discard and pick the top three to remove. Common targets are cling film (use reusable lids or beeswax wraps), sandwich bags and produce bags (use cloth or mesh).
18. Switch to a solid shampoo bar and solid dish soap by March. Solid formats avoid plastic bottles, and one bar typically replaces two to three bottles.
19. Take batteries, small electronics and unused medicines to the right collection point. In Germany, retailers take back batteries, and you should check your municipality’s advice on medicines, since many advise the residual waste bin and not the sink or toilet. In the UK, retailers take back electronics and pharmacies take back medicines, and in Canada, Call2Recycle covers batteries.
20. Stop buying single-use plastic water bottles by using a filter jug or a tap. Where tap water is safe, a filter jug costs little and replaces many bottles a year.

Fashion and consumption

21. Buy no new clothing for three months. Estimates of fashion’s share of global greenhouse gas emissions range from about 2 to 8%, depending on the source. A pause breaks the buying habit and shows what you actually need.
22. Check second-hand first. Look at Vinted, Kleinanzeigen, eBay, charity shops or local swaps before buying new. It extends garment life, avoids new production and saves money.
23. Wash at 30°C instead of 60°C. Lower temperatures use roughly half the energy per cycle, and modern detergents work well at 30°C for everyday loads.
24. Look for GOTS or Fairtrade certification when you buy new. The Global Organic Textile Standard (GOTS) covers chemical use and social criteria along the supply chain. Note that the EU’s Empowering Consumers Directive has banned generic green claims since September 27, 2026, so look for certification, not vague labels.
25. Host or join a clothing swap. A swap is free and social, and it circulates garments that would otherwise be discarded.

Finance and systemic change

26. Check your bank’s fossil fuel financing record. BankTrack and the Banking on Climate Chaos report track it, and the 2023 edition found that major banks provided USD 673 billion in fossil fuel financing in 2022. Banks with published exclusion policies include GLS Bank and Triodos in Germany, Triodos and Charity Bank in the UK, and Vancity, a values-based credit union, in British Columbia. Compare fees and services, and treat this as general information, not financial advice.
27. Check whether your pension is invested in fossil fuels. Make My Money Matter (UK) and Fossil Free Funds (US) provide tools. Most workplace schemes now offer a sustainable fund option, so ask for a switch if it suits you.
28. Set up a regular donation to one evidence-based environmental organisation. Examples include ClientEarth (EU and UK legal advocacy), BUND (Germany), the Environmental Defense Fund (US) and the David Suzuki Foundation (Canada). Regular gifts help these groups plan.
29. Write to your elected representative about a specific environmental issue. In Germany use abgeordnetenwatch.de, in the UK writetothem.com, and in Canada openparliament.ca. Specific, personal messages are more likely to get a response than form letters.
30. Calculate your personal carbon footprint in January and set one reduction target. Use a reputable tool such as the WWF Footprint Calculator, the Umweltbundesamt’s CO2 calculator or Carbonfootprint.com. Identify your largest category, set a quantified target such as cutting food emissions by 30%, and review it quarterly.

The greatest responsibility for systemic change lies with governments and corporations, but individual steps taken with intention and measured against evidence add up. Start with one resolution from each section, build the habit, measure your progress, and then add more.
