Share green ideas with your landlord.  Understanding monetary and maintenance benefits of going green can create incentives to create a more green rental unit atmosphere.

Use soy candles. Soy candles are petroleum free and have less soot, resulting in a cleaner burn without nasty smoke marks.

Get a green shower curtain and avoid curtains that off-gas chemicals that interrupt hormone levels (hormone disruptors).

Use non-leaching aluminum bottles.  The less we use plastic, the better.  While more plastic is recyclable there is growing concern about leached chemicals in plastic to keep it soft for use.

Get houseplants.  Houseplants clean the air.  This guide will help you choose houseplants that do more work for your space.

Swap out incandescent bulbs for compact florescent bulbs.  They use significantly less energy and last much longer.  Advances in color light output make them much more user friendly than they used to be.

Buy or make your own eco-friendly cleaning products.  This can ensure you avoid annoying or harmful off-gassing and even save you money.

Recycle.  This can seem difficult do to lack of space.  Organizing small bins or sharing your green ideas with your landlord (to set aside recycling areas) can help.

Utilize sunlight.  Sunlight has health benefits.  Letting sunlight come in can lessen dependency on electricity (for lights) and even help create a mentally alert and happy atmosphere.

Use reusable bags.  These are great for short trips to local stores and reduce the use of plastic bags.

Use the breeze.  Indoor pollution is usually much higher than outdoor pollution.  Encouraging air circulation by opening windows and door is not only pleasant, it's healthy.
