Drive less
Walk, bike, carpool or take mass transit more often. You'll save one pound of carbon dioxide for every mile you don't drive!

Recycle more
You can save 2,400 pounds of carbon dioxide per year by recycling just half of your household waste.

Check your tires
Keeping your tires inflated properly can improve your gas mileage by more than 3 percent. Every gallon of gasoline saved keeps 20 pounds of carbon dioxide out of the atmosphere.

Use less hot water
It takes a lot of energy to heat water. Use less hot water by taking shorter and cooler showers and washing your clothes in cold or warm instead of hot water (more than 500 pounds of carbon dioxide saved per year).

Avoid products with a lot of packaging
You can save 1,200 pounds of carbon dioxide if you reduce your garbage by 10 percent.

Adjust your thermostat
Moving your thermostat down just 2 degrees in winter and up 2 degrees in summer could save about 2,000 pounds of carbon dioxide a year.

Plant a tree
A single tree will absorb one ton of carbon dioxide over its lifetime.

Turn off electronic devices
Simply turning off your television, DVD player, stereo, and computer, when you're not using them, will save you thousands of pounds of carbon dioxide a year

Eating more vegetables, fruits, whole grains, legumes, nuts, and seeds, and less meat and dairy, can significantly lower your environmental impact. Producing plant-based foods generally results in fewer greenhouse gas emissions and requires less energy, land, and water. Switching from a mixed to a vegetarian diet can reduce your carbon footprint by up to 500 kilograms of CO2e per year (or up to 900 kilograms for a vegan diet).
-Throw away less food

When you throw food away, you're also wasting the resources and energy that were used to grow, produce, package, and transport it. And when food rots in a landfill, it produces methane, a powerful greenhouse gas. So use what you buy and compost any leftovers. Cutting your food waste can reduce your carbon footprint by up to 300 kilograms of CO2e per year.
-Make your money count

Everything we spend money on affects the planet. You have the power to choose which goods and services you support. To reduce your environmental impact, choose products from companies who use resources responsibly and are committed to cutting their gas emissions and waste. If you have money that is being invested for you, through a pension fund for instance, it may be supporting fossil fuels or deforestation. Making sure your savings are invested in environmentally sustainable businesses can greatly reduce your carbon footprint.
