President’s Climate Action Plan

•Reduce carbon pollution from 

power plants

• Prepare the U.S. for the impacts 

of climate change

• Lead international efforts to 

address global climate change

5
This Proposal Deals With the Largest Source 

of GHG Emissions in the U.S.

6
Reducing Carbon Pollution From Power Plants

President’s Directive to EPA:

Develop carbon pollution standards, regulations or 

guidelines, as appropriate, for:

1. New power plants

• Proposed: January 8, 2014

2. Modified and reconstructed power plants

• Proposal: June 2014

• Final: June 2015

3. Existing power plants

• Proposed Guidelines: June 2014

• Final Guidelines: June 2015

• State Plans due: June 2016

7
• Establishes a mechanism for controlling air pollution from 

stationary sources

• Applies to sources for which the Administrator, in her judgment, 

finds “causes, or contributes significantly to, air pollution which 

may reasonably be anticipated to endanger public health or 

welfare”

• Can apply to new, existing, modified and reconstructed sources. 

• More than 70 stationary source categories and 

subcategories are currently regulated under section 111

• A full list of sources regulated under section 111 can be found in 40 

CFR Part 60

8

EPA’s Regulatory Approach

Clean Air Act Section 111
• Lays out different approaches for new and existing 

sources

• New sources under section 111(b)

• Federal standards for new, modified and reconstructed 

sources

• Existing sources under section 111(d) 

• State programs for existing sources that are equivalent to 

federal guidelines

•Applies the “Best System of Emissions Reduction” 

(BSER)

• Feasibility

• Costs

• Technology

• Size of Reductions

EPA’s Regulatory Approach

Clean Air Act Section 111
States and Communities with 

Programs That Reduce Carbon Pollution

State programs that reduce carbon 

include carbon cap and trade programs 

and energy efficiency and renewable 

energy standards or goals. 10
Building Block Strategy EPA Used to 

Calculate the State Goal

Maximum Flexibility:

Examples of State 

Compliance Measures

1. Make fossil fuel-fired

power plants more 

efficient

Efficiency Improvements Efficiency improvements

Co-firing or switching to natural 

gas

Coal retirements

Retrofit CCS (e.g.,WA Parish in 

Texas)

2. Use lower-emitting 

power sources more

Dispatch changes to 

existing natural gas 

combined cycle (CC)

Dispatch changes to existing 

natural gas CC

3. Build more zero/lowemitting energy sourcesRenewable Energy

Certain Nuclear

New NGCC

Renewables

Nuclear (new and up-rates)

New coal with CCS

4. Use electricity more 

efficiently

Demand-side energy 

efficiency programs

Demand-side energy efficiency 

programs

Transmission efficiency

1 From Goal Computation Technical Support Document, Appendix 5 – 2012 Emissions Rate and Building Block Application

2 From Table 1 to Subpart UUUU of Part 60 – State Rate-Based CO2 Emission Performance Goals, Proposed
Flexibilities Available To States

• Timing: 

• Up to 15-year window in which 

to plan for and achieve 

reductions in carbon pollution. 

• Up to two or three years to 

submit final plans. 

• Form of goal: States can use either 

a rate-based or mass-based goal.

• Single or multi-state plans: States 

can collaborate and develop plans 

on a multi-state basis.

• Selection of measures: 

• States will choose how to meet 

the goal through whatever 

collection of measures reflects 

its particular circumstances and 

policy objectives. 

• State measures may impact and, 

in fact may be explicitly 

designed to reduce, CO2

emissions from utilities on a 

regional basis.

• EPA would support building off 

existing reduction programs.

Benefits and Costs

• Estimated costs of the plan are $7.3 billion to $8.8 billion in 2030.

• Estimated benefits by 2030

• CO2 emissions from the power sector reduced by approximately 30% from 

2005 levels.

• Pollutants that contribute to the soot and smog reduced by over 25%

• Avoid an estimated 2,700 to 6,600 premature deaths 

• Avoid 140,000 to 150,000 asthma attacks

• These reductions will lead to public health and climate benefits worth an 

estimated $55 billion to $93 billion in 2030. 

• Health and climate benefits far outweigh the estimated annual costs of 

meeting the standards.

• Proposal protects children and other vulnerable Americans from the 

health threats posed by a range of pollutants.

• Move us toward a cleaner, more stable environment for future 

generations. 

• Ensures an ongoing supply of the reliable, affordable power needed for 

economic growth.
