GREENOVATE BOSTON 2014 CLIMATE ACTION PLAN UPDATE EXECUTIVE SUMMARY6

The Greenovate Boston 2014 Climate Action Plan Update builds upon seven years of work in reducing citywide greenhouse gas (GHG) emissions and prepar-ing for the unavoidable impacts of climate change. Beginning with the 2007 Executive Order, the City of Boston set GHG reduction goals of 25 percent below 2005 levels by 2020 and 80 percent by 2050 for munici-pal operations, and requires the City to plan and pre-pare for the impacts of climate change. In 2011, the City released A Climate of Progress -munity-wide plan, which set the same GHG reduction goals for all of Boston, while continuing to prepare for the impacts of climate change.

goals. Citywide, GHG emissions are 17 percent lower than they were in 2005. Emissions from City govern-ment operations have been reduced by almost 25 per-cent since 2005. Meanwhile, it has become increas-ingly clear that Boston must also prepare for the unavoidable impacts of climate change. The 2014 Update builds upon the 2011 Plan in six key areas:

1. More comprehensive climate preparedness strategies;

2. Cross-cutting themes including social equity, economic development, and public health and safety;

3. More extensive and inclusive community engagement;

4. An updated, more rigorous greenhouse gas inventory and emission projections;

5. A look at Boston’s 80 percent by 2050 GHG reduction goal (80x50);

6. A website that tracks implementation, performance measures, and lessons learned.

subcommittees, active engagement of thousands of people through neighborhood meetings and events, and with support from City staff.

In early 2015, implementation plans for the action items will be developed with continued community input and regular progress updates will be included in the online version. The online version also includes a system of rigorous metrics and targets that connect the strategies to Boston’s carbon footprint.

Equally important to reducing Boston’s GHG emissions are the cross-cutting themes that are critical to creat-ing a more sustainable city. As the City conducts edu-cation and outreach on climate change, Bostonians must understand how climate action addresses their near-term needs. The strategies and actions in the Plan address the importance of community engagement, social equity, public health and safety, and economic development.

The 2014 Climate Action Plan will ensure Boston’s continued global leadership in reducing GHG emissions and preparing for climate change. With this Plan, Boston will continue to develop as a vibrant and sustainable city for current and future generations and champion the actions needed to meet the global challenges of climate change.

Boston reduced GHG emissions by approximately 17% from 2005

through 2013. Most of these reductions were due to a cleaner

electric grid. The next 8% of reductions needed to get to Boston’s

2020 goal will be harder to achieve. Reaching the 2050 goal will

require a transformation of our energy and transportation

infrastructure.
