Bicycles produce no greenhouse gas emissions!

I have been convinced for years of the viability of bicycle transportation and its possibilities of being one of the simplest and most elegant strategies to reduce carbon emissions from transportation. In 2008 I started keeping close track of my bicycle riding miles, as opposed to automobile travel, and how many days I could refrain from automobile use. I also keep track of how many days a year I ride a bike.

Until May of 2011, when we moved to Madison, we lived on a farm in rural Kansas. Bicycle use was much more challenging there, since a lot of travel was on unimproved gravel roadways, and there was a complete absence of dedicated bike paths or lanes. The lower automobile miles after moving to Madison is a direct reflection on how an urban environment with a bicycle-friendly slant has made it possible for me to pare down automobile use to mostly long trips out of town. Below is the record so far.

Tar Sands

The Tar Sands Campaign is fighting Enbridge tar sands pipelines in Wisconsin. Our aims are to block expansion of Line 61 and to halt plans for an adjacent Line 66. We support efforts led by those most impacted, including tribes, landowners, and affected community members.

Divest & Defund

The Divest & Defund Team works to convince institutions that investments in fossil fuels are not only ethically and fiscally irresponsible, but are literally wrecking the planet we call home—all for profit. We are currently focusing on banks that fund pipeline projects.

Community Energy

The Community Energy Campaign focuses on taking responsibility for our own fossil fuel use. We work to create and change policies that impact our energy use and nurture a culture of reducing energy use and using clean, renewable energy to reduce our carbon footprint.
