1 Chapter 4 Natural gas

2 Are we entering a Golden Age of Gas? Natural gas can enhance security of supply: global resources exceed 25 years of current producaon; while in each region, resources exceed 75 years of current consumpaon

3 Natural gas use will grow regardless of the policy landscape World primary natural gas demand by scenario bcm Current Policies Scenario New Policies Scenario 45 Scenario In the New Policies Scenario, demand grows from 3.1 tcm in 29 to 4.8 tcm in 235 an increase of 55% or 1.7% per year

4 UnconvenAonal gas takes a growing share Largest natural gas producers in 235 Russia United States China Iran Qatar Canada Algeria Australia India Norway ConvenLonal UnconvenLonal bcm UnconvenAonal natural gas supplies 4% of the 1.7 tcm increase in global supply, but best pracaces are essenaal to successfully address environmental challenges

5 Gas demand growth comes from China, Middle East, India Natural gas demand by selected region in the New Policies Scenario, 29 and 235 bcm AddiLonal to North America European Union Middle East Russia China India Japan Gas demand grows fastest in the non- OECD regions, led by China, which accounts for more than a quarter of the worldwide increase in demand between 29 & 235

6 Power will be the main driver of demand in most regions Incremental primary natural gas demand by region and sector in the New Policies Scenario, China Middle East E. Europe/Eurasia Other Asia OECD Americas OECD Europe India LaLn America Africa OECD Asia Oceania Power generalon Other energy sector Industry Buildings Other bcm Power generaaon accounts for over 41% of the increase in global gas demand between 29 & 235, as gas is increasingly favoured over coal &, in some cases, nuclear

7 Inter- regional gas trade booms Net gas trade by major region in the New Policies Scenario E.Europe/Eurasia Africa Middle East OECD Oceania LaLn America OECD Americas India OECD Asia China OECD Europe Importers Exporters bcm Gas trade between WEO regions doubles from 59 bcm in 29 to almost 1 2 bcm in 235, with China s imports increasing the most

13 Power investment focuses on low- carbon technologies Share of new power generaeon and investment in the New Policies Scenario, % 35% GeneraLon Investment 3% 25% 2% 15% 1% 5% % Coal Gas Nuclear Hydro Wind Solar PV Renewables are o^en capital- intensive, represenang 6% of investment for 3% of addiaonal generaaon, but bring environmental benefits & have minimal fuel costs

14 New policies help tame the rampant growth in power sector emissions Global CO 2 emission savings in power generaeon relaeve to the 29 fuel mix in the New Policies Scenario Gt More efficient plants Nuclear Hydro Biomass Wind Other renewables CCS 29 fuel mix New Policies Scenario CO 2 emissions reducaons arise mainly from the shi^ away from coal- & oil- fired generaaon towards lower- carbon nuclear and renewables- based technologies

15 Low- carbon power technologies come of age GW Global installed power generaeon capacity in the New Policies Scenario Fossil- fuel addilons Nuclear addilons Renewable addilons ExisLng 21 capacity Renewables and nuclear power account for more than half of all the new capacity added worldwide through to 235

25 The 45 Scenario illustrates what the 2⁰C goal will require World energy- related CO 2 emissions by scenario Gt 45 4 OECD Non- OECD Current Policies Scenario 28% 71% 7 Gt 35 3 New Policies Scenario 33% 15 Gt Scenario 65% Holding greenhouse- gas concentraaon to 45 ppm would limit temperature increase to 2⁰C, compared with 3.5⁰C in the New Policies Scenario & 6⁰C in the Current Policies Scenario

26 MeeAng the 2⁰C goal requires a rapid shi^ away from fossil fuels World primary energy demand by fuel & scenario Mtoe : New Policies Scenario 235: 45 Scenario 2 1 Coal Oil Gas Nuclear Hydro Biomass & waste Other renewables ConsumpAon of coal unsurprisingly falls most in favour of more nuclear & renewables, but the scope of cuang oil use is limited by a lack of commercially viable subsatute fuels

27 Efficiency gains can contribute most to emissions reducaons World energy- related CO 2 emissions abatement in the 45 Scenario relaeve to the New Policies Scenario Gt New Policies Scenario Scenario Abatement Efficiency 72% 44% Renewables 17% 21% Biofuels 2% 4% Nuclear 5% 9% CCS 3% 22% Total (Gt CO 2 ) Energy efficiency measures driven by strong policy acaon across all sectors account for 5% of the cumulaave CO 2 abatement over the Outlook period

28 All countries need to contribute to emissions reducaons Energy- related CO 2 emissions in the 45 Scenario and abatement relaeve to the New Policies Scenario by region, 29 and 235 Gt CO 2 abatement relalve to New Policies Scenario, 235 CO 2 emissions, 235 CO 2 emissions, 29 2 Around three- quarters of the global abatement of CO 2 emissions in the 45 Scenario relaave to the New Policies Scenario occurs in 5 countries and in the European Union China United States India European Union Russia Japan Other OECD Other non- OECD

29 The power sector holds the key to geang emissions down World energy- related CO 2 abatement by sector in the 45 Scenario compared with the New Policies Scenario Power generalon Reduced electricity demand Transport Industry Buildings Other sectors Gt - 15 The power sector accounts for 2/3 of cumulaave emissions abatement to 235, through switching to less carbon- intensive generaaon, more efficient plant & lower electricity demand

30 Climate policy acaon would cut local & regional polluaon Emissions of major air pollutants by region in the 45 Scenario Mt 1 8 OECD Non- OECD Sulphur dioxide Nitrogen oxides ParLculate mafer Policies to cut CO 2 emissions also have the effect of reducing substanaally emissions of other air pollutants that have a negaave impact on human health & the environment

31 ...and cut the cost of imported oil Oil- import bills in selected regions by scenario Billion dollars (21) : New Policies Scenario 235: 45 Scenario Japan United States India European Union China Lower oil- import requirements & internaaonal oil prices slash the oil- import bills of imporang countries as a group by $8.4 trillion over

32 The door to 2 C is closing, but will we be locked- in? World energy- related CO 2 emissions in the Current Policies and 45 Scenarios and from locked- in infrastructure in 21 and with delay Gt C trajectory 2 C trajectory Delay unel 217 Delay unel 215 Emissions from exiseng infrastructure Without further acaon, by 217 all CO 2 emissions permiled in the 45 Scenario will be locked- in by exisang power plants, factories, buildings, etc.

33 Delayed CCS or second thoughts on nuclear make 2 C even harder CumulaEve share of abatement relaeve to the New Policies Scenario in the 45 Scenario, Delayed CCS 45 Case and Low Nuclear 45 Case Share of abatement 1% 8% 6% 4% 2% Trillion dollars (21) Efficiency Renewables Biofuels Nuclear CCS AddiLonal investment (right axis) % 45 Scenario Delayed CCS 45 Case Low Nuclear 45 Case 14.5 If CCS deployment was delayed or nuclear not deployed as expected in 45, miagaaon costs would rise and put unprecedented pressure on other technologies

34 Coal has to bear the brunt of emissions reducaons World energy- related CO 2 emissions by fossil fuel in the 45 Scenario Gt Coal Oil Gas Gas overtakes coal by 235 as the 2 nd - largest source of emissions, with coal- based emissions peaking early in the projecaon period & falling rapidly therea^er

35 The cheapest kwh of electricity is that which is not consumed Change in world energy- related CO 2 emissions from the power generaeon sector in the 45 Scenario compared with the New Policies Scenario Reduced demand Renewables Nuclear CCS More efficient use of fossil- fuel plants - 8 Gt - 1 Widespread emissions trading, enabling policies for low- emissions technologies, stronger support to renewables & energy- efficiency measures drive power- sector emissions savings

36 A big shi^ in investment is required CumulaEve energy sector investment by scenario, Trillion dollars (21) Total supply side investment New Policies Scenario 45 Scenario Industry Buildings Transport Biofuels Power plants Power T&D Oil Gas Coal Change in investment rela>ve to New Policies Scenario Scenario Trillion dollars (21) Investments need to be shi^ed away from fossil fuels towards low carbon technologies, and improved energy efficiency across all sectors

37 Delaying acaon is a false economy Change in investment in power generaeon in the Delayed 45 Case, relaeve to the 45 Scenario Billion dollars (21) Renewables Nuclear Gas and coal plants retrofitted with CCS Efficient coal plants and coal plants fitted with CCS Gas plants including plants fitted with CCS Inefficient coal Net change in investment Delaying acaon unal 215 reduces investment costs in the period unal 22, but for every $1 saved, an addiaonal $4.3 must be spent in to compensate
