  • Annual averages of the global mean sea level (mm). The red curve shows reconstructed sea level fi elds since 1870 (updated from Church and White, 2006); the blue curve shows coastal tide gauge measurements since 1950 (from Holgate and Woodworth, 2004) and the black curve is based on satellite altimetry (Leuliette et al., 2004). The red and blue curves are deviations from their averages for 1961 to 1990, and the black curve is the deviation from the average of the red curve for the period 1993 to 2001. Error bars show 90% confi dence intervals.
  • For the Arctic as a whole, there was a substantial loss in glacial volume from 1961 to 1998. Glaciers in the North American Arctic lost the most mass (about 450 km3), with increased loss since the late 1980s. Glaciers in the Russian Arctic have also had large losses (about 100 km3). Glaciers in the European Arctic show an increase in volume because increased precipitation in Scandinavia and Iceland added more to glacial mass than melting removed over that period.
  • Solid lines are multi-model global averages of surface warming (relative to 1980-99) for the scenarios A2, A1B and B1, shown as continuations of the 20th century simulations. Shading denotes the plus/minus one standard deviation range of individual model annual averages. The orange line is for the experiment where concentrations were held constant at year 2000 values. The gray bars at right indicate the best estimate (solid line within each bar) and the likely range assessed for the six SRES marker scenarios. The assessment of the best estimate and likely ranges in the gray bars includes the AOGCMs in the left part of the figure, as well as results from a hierarchy of independent models and observational constraints.
  • Energian kulutus on kasvanut tasaisesti vuosi vuodelta. Keskeisimmät syyt kulutuksen voimakkaaseen laskuun vuonna 2005 olivat erittäin leuto talvi, metsäteollisuuden tuotannon lasku työselkkauksen vuoksi sekä tavanomaista huonompi suhdannetilanne terästeollisuudessa. Vuonna 2006 energiankulutus oli noin 35 Mtoe eli noin 1500 PJ.

  • Climate Change and Energy Updated PowerPoint show about climate change and energy sector
  • Research results of climate change
  • Global warming is due to strengthened greenhouse effect Greenhouse effect The Earth has a natural temperature control system. Certain atmospheric gases are critical to this system and are known as greenhouse gases. On average, about one third of the solar radiation that hits the earth is reflected back to space. The Earth's surface becomes warm and as a result emits infrared radiation. The greenhouse gases trap the infrared radiation, thus warming the atmosphere. Naturally occurring greenhouse gases create a natural greenhouse effect. However, human activities are causing greenhouse gas levels in the atmosphere to increase. Source: National Geographic
  • Earth’s energy budget Source: Nasa, Atmospheric Science Data Center
    • The six greenhouse gases under the Kyoto Protocol:
    • Carbon dioxide or CO 2
    • Methane or CH 4
    • Nitrous oxide or N 2 O
    • Perfluorocarbons or PFC compounds
    • Hydrofluorocarbons or HFC compounds
    • Sulphur hexafluoride or SF 6
    • Other greenhouse gases:
    • Ozone or O 3
    • Bromine compounds or halogens, e.g. CF3Br
    • Freons or chlorofluorocarbons or CFC:s
    • Water vapour or H 2 O (g)
    • Global atmospheric concentrations of greenhouse gases have increased markedly as a result of human activities!
    Strengthening of greenhouse effect is due to increase of greenhouse gases in the atmosphere Source: IPCC Fourth Assessment Report
  • Different greenhouse gases have different meaning to global warming Source: IPCC Fourth Assessment Report
  • Meaning of carbon dioxide to global warming
    • Carbon dioxide is the most important anthropogenic greenhouse gas .
      • The primary source of the increased atmospheric concentration of carbon dioxide results from fossil fuel use in power and heat production as well as transport .
      • The change of land use provides another significant but smaller contribution.
      • The atmospheric concentration of carbon dioxide exceeds by far the natural range over the last 650,000 years .

  • Climate treaties and –policy
  • United Nations Framework Convention on Climate Change
    • The United Nations Framework Convention on Climate Change (UNFCCC or FCCC) is an international environmental treaty produced at the United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit, held in Rio de Janeiro in 1992.
    • Its’ stated objective is to achieve stabilization of greenhouse gas concentrations in the atmosphere at a low enough level to prevent dangerous anthropogenic interference with the climate system.
    • UNFCCC members that ratify this treaty admit officially that climate change is a serious problem.
    • 192 nations have signed the UNFCCC.
    Source: UNFCCC *Tähän diaan on liitettynä muistiinpanoja
  • Kyoto Protocol 1/2
    • The Kyoto Protocol is the principal update of UNFCCC
    • Notable international agreement
      • 178 countries have ratified Kyoto Protocol
    • Countries that ratify this protocol commit to reducing their emissions of carbon dioxide and five other greenhouse gases
      • CO 2 , N 2 O, CH 4 , SF 6 , HFC, PFC
      • carbon dioxide is primary target
    • 2008-2012 developed countries have to reduce their greenhouse gas emissions by a collective average of 5% below their 1990 levels
    • EU will reduce 8 % .
      • Reduction has been shared between EU countries by burden sharing agreement
    Lähde: UNFCCC
  • Kyoto Protocol 2/2
    • Emission reduce targets for 38 countries, e.g.
      • EU-15 - 8 % (Burden Sharing Agreement)
      • USA - 7 % (has not ratified)
      • Japan and Canada - 6 %
      • Australia + 8 % (has not ratified)
      • Russia, Ukraine, New Zealand 0 %
      • Eastern European transition economy countries (not all) - 8 %; incl. 8 new EU countries
    • Eastern European countries have to do nothing. Emission are already well below their levels
    • Many countries haven’t got limits e.g.
      • Oil countries in the Middle-East, China, India, South-America, Asian developing industrial countries, South-Africa,…
      • The idea was that those countries will start reducing their emissions in the future
    Source: UNFCCC
  • Burden sharing in EU-15
    • EU shared targets between member states.
    • Finland have to reduce emissions to same level as 1990.
    • Percentages don’t tell how challenging the target is.
      • The target for Finland is estimated as one of the most expensive in many analyses
    • Finland’s emissions
      • 1990 ca. 71 MtCO 2 -eq.
      • 2008-2012 on average ca. 83 MtCO 2 -eq.

    • 3 %
    Finland´s need to reduce emissions from WM 2008-2012 - 12,2 MtCO2/a + - 2 MtCO2/a*
    • Industry
    • 1,5 MtCO2/a
    • 7 %
    • Electricity and DH
    • 10,6 MtCO2/a
    • 41 %
    New entrants reserve 1,4 MtCO2/a * EU Comission required Finland to reduce the amount of emission allowances by 2 MtCO2/a
  • The EU Emission Trading System 1/2
    • The EU Emission Trading System started 2005
    • Aim is reduce green house gas emissions and reach Kyoto target.
    • Companies that are in emission trading system are bound to:
      • apply for a permission to green house gas emissions
      • track and validate the actual emissions in accordance with the relevant assigned amount
      • retire the allowances after the end of each year
    • Member states set a quota for GHG emissions
      • the total amount of allowances is less than the amount that would have been emitted under a business-as-usual scenario.
  • The EU Emission Trading System 2/2
    • The second phase (2008-12) expands the scope significantly:
      • emission allowances available 200 MtCO 2 /year less than 2005-2007
      • companies will reduce emissions or buy emission allowances
      • total emissions will reduce
      • Finland has emission allowances 16 % (8 Mt CO2/year ) less than 2005
      • Reduction has been allocated mainly to power and district heating production.
  • Emission trade sectors
    • Energy Industry
      • over 20 MW (thermal) power plants, oil refineries and coke furnaces
      • under 20 MW power plants for district heating if in same network is one or more over 20 MW power plant in Finland
      • Excluding incineration of municipal and hazardous waste
    • Steel Industry
      • roasting and sintering units of metallic minerals
      • iron and steel production and founding if production capacity is over 2,5 t/h
    • Construction Industry
      • Production of cement, lime, glass, fiberglass, bricks, porcelain and burned stone products.
    • Paper and Forrest Industry
      • Production of pulp, paper and board if production capacity is over 20 t/h
  • Scope of emission trading
    • Emission trading covers ca. 60 % greenhouse gas emissions of the EU.
      • 500 Energy and Industry plants in Finland
      • 12 000 plant in the EU
    • Possibly enlarging the scope of the scheme to new sectors, including aviation, petrochemicals, ammonia and the aluminum sector, as well to two new gases (nitrous oxide and perfluorocarbons)
    • All 27 countries of the EU are in emission trading
  • Emission trading affects fuel prices and competitiveness
  • Purpose of the emission trading system is to affect demand and supply through CO 2 price
    • Emission free and low emission energy sources will gain competitive edge
      • enhance investments and increase utilization factors
      • One funding source for new investments is the emission allowances of high CO2 emission energy sources
    • Changes in product prices effect the demand
    • Competition on the market aims to minimize price increase
    The goal is to reduce green house gas emissions in a cost-effective way
  • Emission trading and Kyoton mechanisms ” Additional” emission allowances through Kyoto mechanisms by the state (JI, CDM, Global ETS) Installations in EU ETS ca. 55 % of emissions CO2 emissions from other sectors and other GHG ca. 45 % of emissions Additional emission allowances through EU ETS Additional emission allowances through Kyoto mechanisms Finland’s emission ceiling 2008-2012 (ca. 71 MtCO2-ekv/a without Kyoto mechanisms and EU ETS)
  • Climate Policy - Responsibilities 2008-2012
  • Link directive brings to the carbon market emission reductions though so called Kyoto- mechanisms
    • Link directive published 13.11.2004, In Finland implemented by changing the emission trading law 12.1.2007
    • Makes it possible to utilize emission reduction executed outside EU in EU’s ETS
      • Clean Development Mechanism (CDM)-projects executed in developing countries provide CER-units, which have been used since 2005
      • Joint Implementation (JI) -projects executed in industrial countries provide ERU-units, which have been used since 2008
    • Limits the price increase of emission allowances in the EU
    • Makes the carbon market global
    • CDM, Clean Development Mechanism,
    • CDM is an arrangement under the Kyoto Protocol allowing industrialized countries with a greenhouse gas reduction commitment to invest in projects that reduce emissions in developing countries as an alternative to more expensive emission reductions in their own countries. Distribution of CDM emission reductions, by country. The CDM allows net global greenhouse gas emissions to be reduced at a much lower global cost by financing emissions reduction projects in developing countries where costs are lower than in industrialized countries
    • Additionality A crucial feature of an approved CDM carbon project is that it has established that the planned reductions would not occur without the additional incentive provided by emission reductions credits, a concept known as "additionality".
    Flexibility mechanisms (Kyoto mechanisms) 1/2
  • Flexibility mechanisms (Kyoto mechanisms) 2/2
    • JI, Joint Implementation
    • Through the Joint Implementation, industrialized countries with a greenhouse gas reduction commitment (so-called Annex 1 countries) may fund emission reducing projects in other industrialized countries as an alternative to emission reductions in their own countries. Typically, these projects occur in countries in the former Eastern Europe. Emission reductions are awarded credits called Emission Reduction Units (ERUs).
  • Climate credits (Carbon credits)
    • Emission Reduction Unit, ERU Emission reduction unit (ERU) refers to the reduction of greenhouse gases, particularly under Joint Implementation, where it represents one tonne of CO2 equivalent reduced.
    • Certified Emission Reduction, CER Like ERU, but CERs are climate credits (or carbon credits) issued by CDM.
  • Future Prospects
  • Growth scenario of global energy use
  • Electricity supply by energy sources scenario in Finland
  • Development of power consumption
  • Target of United Nations Framework Convention on Climate Change is stabilize greenhouse gas emissions to safety level 5 10 15 20 25 Source: UK DEFRA CO 2 -emissions (GtC) Basic Scenario Developed countries Undeveloped countries 550 ppm stabilization 0 30 1990 2000 2010 2020 2030 2040 2050 2060 2070 2080 2090 2100 450 ppm stabilization
  • Scenarios compared to actual emissions
  • EU in international climate negotiations
    • Communication on Limiting Global Climate Change to 2 degrees Celsius
    • Independent commitment to reduce GHG emissions by 20% from 1990 level
    • If an international agreement signed, 30% GHG reduction compared to 1990 + developing CDM
    • Targets will be reached by:
    • Developing EU ETS
    • Improving energy efficiency (20 % by 2020)
    • Increasing share of renewable energy (20 % by 2020)
    • CCS-technology, other R&D, reducing emissions from transportation and other sectors
  • Finland’s energy and climate strategy and current political climate –Kyoto period
    • Main Messages of the Government
      • All energy sources must be exploitable
      • Renewable energy must be promoted
      • Industrial Electricity Tax reduced
      • Major Part (ca.8Mt/a) of the emission reduction allocated to emission trading sector, other sectors need to reduce emission 1Mt/a
      • Finland (state) will utilize Kyoto mechanisms 2Mt/a

  • Carbon Capture and Storage - CCS
    • CCS is an approach to mitigate global warming by capturing CO 2 from large point sources such as fossil fuel power plants and storing it. Technology for large scale capture of CO 2 is already commercially available and fairly well developed. Although CO 2 has been injected into geological formations for various purposes, the long term storage of CO 2 is a relatively untried concept and as yet no large scale power plant operates with a full CCS system.
    • CCS could reduce CO2 emissions approximately 80-90%, increase the fuel needs of a coal-fired plant with CCS by about 25% and increase the cost of energy from a new power plant with CCS by 21-91% [ IPCC special report on Carbon Dioxide Capture and Storage 2005]
  • CO 2 capture
    • In post-combustion, the CO 2 is removed after combustion of the fossil fuel - this is the scheme that would be applied to conventional power plants. Here, carbon dioxide is captured from flue gases at power stations. The technology is well understood and is currently used in other industrial applications.
    • Pre-combustion is widely applied in fertilizer, chemical, gaseous fuel (H 2 , CH 4 ), and power production. In these cases, the fossil fuel is partially oxidized, for instance in a gasifier. The resulting syngas (CO and H2) is shifted into CO 2 and more H 2 . The resulting CO 2 can be captured from a relatively pure exhaust stream. The H 2 can now be used as fuel; the carbon is removed before combustion takes place.
    • In Oxy-fuel combustion the fuel is burned in oxygen instead of air. To limit the resulting flame temperatures to levels common during conventional combustion, cooled flue gas is recirculated and injected into the combustion chamber. The flue gas consists of mainly carbon dioxide and water vapour, the latter of which is condensed through cooling. The result is an almost pure carbon dioxide stream that can be transported to the sequestration site and stored.

  • CO 2 Storage (sequestration)
    • Various forms have been conceived for permanent storage of CO2. These forms include:
      • gaseous storage in various deep geological formations (including saline formations and exhausted gas fields)
      • liquid storage in the ocean
      • solid storage by reaction of CO2 with metal oxides to produce stable carbonates
