The document discusses the persistent rise in global greenhouse gas emissions, despite some encouraging trends in major emitters like the US and China. It identifies four key measures to halt emissions growth by 2020 while maintaining economic growth, including improving energy efficiency and limiting inefficient coal use. The importance of the energy sector adapting to climate change is emphasized, alongside the need for international cooperation ahead of a global agreement expected in 2020.

Context
 Climate change is slipping down the policy agenda,
even as the scientific evidence continues to accumulate
 Energy sector accounts for two-thirds of greenhouse gas emissions
 Mixed news on energy trends
Price dynamics between gas and coal support emissions
reductions in some regions, but impede them in others
Renewables are on the rise, but investment slowed in 2012
Efficiency policies are gaining momentum in many countries
Nuclear is facing challenges and CCS still remains distant

In 2012, total CO2 emissions in the US were back at the level of the mid-1990s,
while total CO2 emissions growth in China was one of the lowest in the last decade

Four measures to keep the 2 °C target alive
 National efforts in this decade need to buy time for an international
agreement, expected to come into force in 2020
 Measures to 2020 should meet key criteria:
 Significant near-term emissions reductions
 No harm to countries’ economic growth
 Reliance only on existing technologies and proven policies
 Significant national benefits other than climate change mitigation
 Our 4-for-2 °C Scenario proposes four measures that meet these
criteria

emissions growth by 2020
Emissions savings in the 4-for-2 °C Scenario, 2020
Four measures can stop the growth in emissions by 2020 at no net economic cost,
reducing emissions by 3.1 Gt, 80% of the savings required for a 2 °C path

Measure 1: Improve energy efficiency
Emissions savings in the 4-for-2 °C Scenario, 2020
Energy efficiency reduces emissions by 1.5 Gt, led by minimum energy performance
standards – additional investment is more than offset by fuel bill savings

In 2010, methane releases were 1.1 Gt CO2-eq;
halving the level in 2020 would save twice the gas production of Nigeria today

Key messages
 Despite encouraging steps in some countries, global emissions
keep rising and the scientific evidence of climate change increases
 Early national action is required while negotiating towards a
global deal in Paris in 2015 that then comes into force by 2020
 Four measures can stop emissions growth by 2020 and keep the
2°C target alive, without harming economic growth
 There is a need for parallel action to deploy critical low-carbon
technologies at scale after 2020, including CCS
 The energy sector must adapt to climate change, both in the
resilience of its existing assets and in future investment decisions
