1. Insulate your home

From installing a heat pump to turning down the heating, there is <a href="https://www.bbc.co.uk/news/uk-58967580">a raft of changes around the home that can help the planet </a>."Switching from a gas or oil-powered heating system to an electric heat pump makes a considerable difference," according to Dr Neil Jennings, an academic from Imperial College London.We can change our homes by improving insulation in our walls, ceilings and windows.Draught-proofing is one of the cheapest and most effective ways to save energy, <a href="https://energysavingtrust.org.uk/advice/draught-proofing/">according to the Energy Saving Trust (EST) </a>.

Livestock creates <a href="https://www.fao.org/news/story/en/item/197623/icode/">14% of all greenhouse gases </a>, with cattle being by far the largest contributor. Dr Jonathan Foley, who investigates climate change solutions, says you can <a href="https://www.bbcgoodfood.com/howto/guide/how-reduce-food-waste">save money and reduce waste </a>by making smaller portions and saving leftovers for later at home. The world wastes between 25% and 30% of its food, according to the <a href="https://wrap.org.uk/taking-action/food-drink/actions/action-on-food-waste">Waste & Resources Action Programme </a>.

2. Changing The Way We Shop & Eat.

Living car-free might be "the most impactful thing we can do to reduce our transport emissions", according to Dr Jennings. Small steps still have an impact, like walking and cycling to the local shops or sharing car journeys with friends or neighbours. Electric cars are becoming more widespread, but they are still expensive. And it is only truly green travel if the electricity used to power the car comes from green energy sources, such as wind or solar. Low-carbon sources made up <a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1016822/UK_Energy_in_Brief_2021.pdf">58% of the UK's electricity in 2020, including nuclear </a>.

3. Change The Way We Commute Or Travel

Switching to a green energy provider or a green tariff can significantly reduce your household's carbon footprint. But a recent increase in wholesale energy price means many providers have withdrawn their offers.

4. Green Energies

Humanity only has 100 Months to Agree upon and deploy Climate Solutions before Human Extinction becomes A likely inevitability.

Small changes to our lifestyles and choices could limit our personal carbon footprint.
