Climate Change and Energy Use


Climate change is perhaps the biggest challenge we face this century.  While natural cycles of warming and cooling characterize Earth’s history, human activities have heightened recent warming.  Our overuse of fossil fuels, such as oil, are a significant source of this problem.   Reducing our oil usage in transportation will not only begin to address global warming, but lead to more diverse energy use.  WILMAPCO has been considering these issues for some time.


The greenhouse effect is a result of greenhouse gases (GHGs), such as carbon dioxide and methane, trapping the sun’s energy in our atmosphere rather than allowing it to escape into space.   Levels of GHGs have intensified the greenhouse effect beyond what can be attributed to natural cycles, leading to increases in average global temperatures. View this BBC Guide for some illustrations.

Alterations in weather patterns resulting  from the greenhouse effect are known as climate change.  While tough to predict, serious global consequences can result from this change.  Visit the Intergovernmental Panel on Climate Change website for details.

Fossil fuels are a major source of GHGs.  As shown in the graph below, our oil-dependent transportation system accounted for some 26% of GHG emissions in the U.S. in 2014.


Reducing our oil dependence and improving transportation’s energy efficiency makes for good environmental, political and economic policy.

In the transportation sector, we feel these two issues can be tackled simultaneously by:

  • Reducing growth of vehicle miles traveled (VMT)
  • Improving system and operational efficiencies
  • Transitioning to low-GHG fuels
  • Improving vehicle technologies

Current Efforts

Our Regional Transportation Plan (RTP) contains objectives and actions that, if implemented, would both address climate change and lower energy use.  Many actions could lead to the reduction of the region’s greenhouse gas (GHG) emissions, in turn slowing warming.  Such actions include:

  • Greater investment in public transit
  • Greater investment in the non-motorized network
  • Measures to boost ride-sharing
  • Steps to ease highway congestion
  • Supporting investments relevant to surrounding land-use



We are working with local and federal partners to develop the best ways to check global warming and reduce energy use in our transportation system.  We have, for example, joined with the Environmental Protection Agency and other MPOs in the Mid-Atlantic to share ideas about environmental sustainability.  In Delaware, we participated in the update of the State’s Energy Plan, developing recommendations to curb energy use through reductions in VMT and the promotion of more energy-efficient vehicles.  Follow this link for that plan’s recommendations.



Sea-level Rise (SLR) is a consequence of rising global temperatures, one that threatens the transportation systems of coastal regions with increased flooding and complete inundation.
