History & Overview• Paris agreement:
• Country NDC targets for 2025/2030
• Long-term global goal of remaining
well below 2°C of warming
• Invited Parties to submit mid-century
low-GHG gas strategies by 2020.
• Canada, Mexico and U.S. and Germany
released their mid-century strategies at
COP22 in Marrakech November 2016
• Sets out a long-term vision for cost-
effectively decarbonizing our economy
• Illustrates pathways to achieve an 80
percent economy-wide emission
reduction by 2050
• Describes U.S. action across 3 major categories:
• Transitioning to a low-carbon energy
system
• Sequestering carbon through forests, soils
and CO2 removal technologies
• Reducing non-CO2 emissions such as
methane, nitrous oxide and HFCs

Main Scenarios and Negative Emissions Scenarios
Benchmark Scenario: Technology assumptions from DOE Advanced Technology Case; maintained land
carbon sink and a broad range of low-GHG technologies, including CO2 removal technologies
No CO2 Removal Technology Scenario: CO2 Removal technologies like bioenergy w/carbon capture and
storage (BECCS) are unavailable
Limited Sink Scenario: Limited availability of CO2 removal technologies and limited success in
maintaining and enhancing the land sink

MCS Vision for a Low-Carbon U.S. Energy System in 2050
1. Improving energy efficiency, including smart growth.
2. Near-complete decarbonization of electricity.
3. Switching to electricity and other low-carbon fuels in transportation, buildings, and industry.

The combination of technology advances and additional policies can drive
greater emission reductions than the sum of each approach on its own.

Electricity Strategy
• Near-complete decarbonization, driven by deployment of renewable energy
(primarily wind and solar), nuclear energy, and fossil-fuels and bioenergy with CCS
• A major expansion of generation resources supports both economic growth and the
electrification of other sectors

Transportation Strategy
• Increasing fuel efficiency
• Developing low-carbon transportation fuels and vehicles, including electric vehicles, fuel cell electric vehicles and biomass-fueled vehicles
• Reducing vehicle miles traveled through smart growth and other strategies

Buildings Strategy
• Increasing energy efficiency
• Increasing electrification of end-uses

Industry Strategy
Two crosscutting themes:
• Efficiency improvements in new materials and methods
• Switching to low-carbon fuels and feedstocks, including clean electricity
Industry is very heterogeneous, so decarbonization will be
industry- and process-specific.

Opportunities for Reducing Non-CO2 Emissions
• MCS Benchmark non-CO2 emissions in 2050 decline modestly compared to current
levels but are ~50% lower than the No Mitigation scenario in 2050.
• The Mid-Century Strategy does not account for major technological advances that
may be achievable with increased RD&D investment to identify and drive down the
costs of opportunities to further reduce non-CO2 emissions.

Reducing Net Emissions with U.S. Lands
• Finding efficient ways to structure carbon-based incentives in the land sector will
be important
• Achieving land sector goals of MCS will require cooperation across a diverse group
of stakeholders
• Carbon reporting, accounting and monitoring tools can ensure that we are
supporting cost-effective and flexible mitigation strategies
• Timing of land action is critical, and delivering significant land sequestration by
2050 requires investing soon.
• Policy “check points” are vital to assess the impacts of these activities on the land
sector
2050 land sector and
CO2 removal
technologies could
sequester 30 to 50
percent of economy-
wide GHG emissions

The combination of technology advances and additional policies can drive
greater emission reductions than the sum of each approach on its own.
MCS scenarios that achieve 80 percent reductions in economy-wide net GHG emissions show energy CO2 reductions of 74 to 86
percent.
