Food and Water Action "OFF Fossil Fuels" pledge: https://www.foodandwateractionfund.org/content/elected-official-pledge

I accept the science that says humankind’s use of fossil fuels is the primary driver of dangerous global climate change.
  Therefore, as your elected representative, I pledge to be a leader on climate change issues and will support efforts in my community to move us off fossil fuels and achieve a just transition to 100% clean, renewable energy. While current research suggests that this transition will need to be completed by 2035 at the latest to avoid catastrophic climate impacts, we cannot wait and must act now.
  I will oppose any project that will expand fossil fuel production, and its use or transport, and will work to quickly phase out existing fossil fuel infrastructure in my jurisdiction.  I vow to put people and the planet before any corporation’s profits, and will support efforts to address the toxic legacy of fossil fuels in all of our communities, especially those most impacted including indigenous peoples, communities of color, low income people and rural communities.
