Implementing mitigation actions can bring social, economic and environmental co-benefits. The sectors with the biggest mitigation potential are: energy, industry, transport, agriculture, forestry and waste. Given the fundamental changes required to achieve low carbon development, mitigation actions needs to be integrated with broader development goals and plans. Many countries have made pledges to reduce their emissions. However current pledges are not sufficient to prevent dangerous climate change (global temperature increase beyond 2°C). There are several international mechanisms to support mitigation, many of them created under the Kyoto Protocol.

- This section provides a definition of climate change mitigation and related concepts. It further gives an overview of greenhouse gases (GHGs), current emission levels, as well as pledges of different countries to reduce GHG emissions in the future. The section concludes with some examples of co-benefits of climate change mitigation.
- In order to prevent dangerous anthropogenic interference with the climate system, actions need to be taken to stabilize greenhouse gas concentrations in the atmosphere. Such actions are referred to as “climate change mitigation”. More specifically, mitigation involves: reducing GHG emissions, e.g. by making older equipment more energy efficient; preventing new GHG emissions to be released in the atmosphere, e.g. by avoiding the construction of new emission-intensive factories; preserving and enhancing sinks and reservoirs of GHGs, e.g. by protecting natural carbon sinks like forests and oceans, or creating new sinks (“carbon sequestration”). UNFCCC (2009). Fact Sheet: The Need for Mitigation UNEP website/
- Mitigation Options: In order to reduce or limit GHG emissions and/or increase carbon sequestration, a variety of mitigation options can be taken. They can be as complex as a low-emission plan for the energy sector, or as a simple as improvements to a cook stove design. Mitigation options can vary greatly from one country to the other and need to be adapted to specific national circumstances (referred to as “Nationally Appropriate Mitigation Actions” – NAMAs). Low Carbon and Green Economy: In a nutshell low carbon development implies ‘using less carbon for growth’. The term green economy likewise encompasses the reduction of greenhouse gas emissions, but also covers other environmental issues which are not directly related to climate change (such as protecting human health and the environment from mercury). The green economy concept also puts emphasis on social benefits. Mulugetta Y. & Urban, F. (2010). Deliberating on Low Carbon Development. Energy Policy UNEP (2010). Towards a Green Economy UN Sustainable Development Knowledge Platform
- In order to make informed mitigation decisions, it is important to consider different greenhouse gases, their sources and contribution to climate change. The most important gas in terms of quantitative emissions is carbon dioxide. It accounted for 76% of total GHG emissions in 2010. Other important factors to be considered include the capacity of different gases to trap heat in the atmosphere, or their so-called “global warming potential” (GWP), as well as the time a certain gas remains in the atmosphere (see Module 1 on Climate Change Science for further information). IPCC (2007). Fourth Assessment Report UNEP (2012). The Emissions Gap Report, p11
- The global community has committed itself to hold warming below 2°C (compared to pre-industrial temperatures) to prevent dangerous climate change. The 2013 IPCC report on the physical science basis of climate change provides a “budget approach” to this goal, looking at total allowable CO2 emissions level to meet the 2°C target. The report states that in order to have a greater than two in three chance of keeping global warming below 2°C, cumulative emissions of CO2 cannot exceed 1,000 Gigatonnes of carbon (GtC). As of 2011, more than half this amount, or over 500 GtC, has already been emitted since 1861-1880. When the effects of other greenhouse gases are included, even less CO2 could be emitted to keep below a 2°C warming. Current annual emission levels are at 9.5 GtC and are likely to grow every year due to population growth and economic development patterns. If annual emissions continue to grow as in past years (“business as usual” scenario) the carbon budget will be exhausted in the next three decades. IPCC (2013). Climate Change 2013 – The Physical Science Basis, Summary for Policymakers Further information: The 2°C target is not universally agreed. Small Island Developing States (SIDS) and Least Developed Countries (LDCs) have identified global warming of 1.5°C as warming above which there would be serious threats to their own development and, in some cases, survival.
- In Copenhagen in 2009, Parties to the UN Framework Convention on Climate Change (UNFCCC) made pledges to reduce their GHG emissions to keep temperature increase below 2°C. The pledges were formalized in the Cancun Agreements in 2010 (see also Module 2). This map shows the different categories of pledges made by countries. Furthermore, many countries provided information on planned actions to mitigate emissions, without specifying concrete reduction targets. UNEP (2012). The Emissions Gap Report, Executive Summary
- UNEP’s 2012 Emissions Gap Report states that there is a significant gap between current pledges and emission reductions needed to meet the 2° goal. According to the report, emissions would need to peak before 2020 and be at about 44 Gt of equivalent carbon dioxide (CO2e) per year in order to have a likely chance of meeting the 2ºC target. Depending on countries’ capacity and willingness to implement reductions pledges and the effectiveness of accounting rules, there are several possible scenarios for emission levels in 2020, that are consistent with the current reduction pledges. The most optimistic scenario (case 4) sets emissions in 2020 at 52 GtCO2e level. If countries, both developed and developing, fully implement their reduction targets, this will reduce emissions to below the ‘business-as-usual’ level in 2020 but not to a level that is in line with the agreed upon target of 2°C (i.e. about 44 GtCO2e). This projection presents a minimum of a 8 GtCO2e gap of necessary emission reductions, and currently there is no indication as to how this gap is going to be closed. UNEP (2012). The Emissions Gap Report, p2 & 3
- If emission targets are not raised in the coming years, we can expect a level of global temperature increase considerably higher than 2°C. The graph shows that with a fossil fuel intensive business-as-usual pathway (IPCC SRESA1FI), warming will exceed 4°C towards the end of the 21st century. If current emission pledges by developed and developing countries are achieved, this is likely to translate into a global warming of 3°C by 2100. However more can be done. There are technically and economically feasible emission pathways that could limit warming to 2°C by 2100, with is the agreed level above which ‘dangerous’ global warming will occur. With developing countries increasingly contributing to GHG emissions growth in the atmosphere, the responsibilities for mitigating climate change is shared and substantial emission reductions are needed on the part of both developed and developing countries, as further illustrated in the following slides. IPCC (2007). Fourth Assessment Report World Bank (2012). Turn Down the Heat, p23 & 24
- The following three graphs compare past, current and expected GHG emission levels for G20 countries that made mitigation pledges. (European countries are depicted as a group.) The present graph shows total emissions per country. In 1990, the largest emitter was the United States of America. However, in 2010 the USA was clearly surpassed by China in terms of total emissions. The difference is even more pronounced when it comes to projected emission levels for 2020. The following slides look at emission levels on a Gross Domestic Product (GDP) and per capita basis. UNEP (2012). The Emissions Gap Report, p19
- This graph depicts GHG emissions per unit of GDP. In the case of China, the decrease in GHG per unit of GDP from 1990 to 2010 indicates the extent to which China has managed to decouple GHG emissions from economic growth. However, emissions per unit of GDP remain often higher in developing countries than in developed countries, in particular if a lot of emissions come from the forestry sector, as is the case in Indonesia. UNEP (2012). The Emissions Gap Report, p19
- This graph shows emission levels per capita. While China’s total emissions are high, the per capita emissions are relatively low. Countries such as Australia, Canada and USA, with very high per capita emissions, might achieve an overall reduction by 2020 if they meet their pledges, but in comparison to other countries their per capita emissions would still remain high. UNEP (2012). The Emissions Gap Report, p20
- While climate change mitigation is often discussed in terms of constraints, there are actually various environmental, economic, and social co-benefits that may arise as a result of mitigation actions. For example, forest conservation limits GHG emissions while at the same time protecting biodiversity and ecosystems. The promotion of renewable energies can lead to increased local employment due to decentralized energy production. Reducing GHG emissions has health benefits e.g. through lower urban air pollution concentrations. Successful mitigation measures can also lead to potential cost savings due to a reduced need for adaptation actions.
- Farming communities around the world are embracing alternative methods of obtaining energy that are more affordable and better for the environment. In China, a Government programme is helping poor farmers convert animal and human waste into biogas, improving the livelihoods of families while contributing to climate change mitigation. The programme is supported by the International Fund for Agricultural Development (IFAD).
- This section explores opportunities for integrating mitigation into development planning through Low-Emission Development Strategies (LEDS). It first introduces basic characteristics and elements of LEDS. The section then provides examples of policy instruments and other mitigation actions that could be promoted through LEDS.
- Mitigating climate change requires a fundamental change in the way decision-makers, the public and the private sector perceive and pursue economic development. The slide presents three important dimensions of low carbon development, including new political thinking, more resource efficient patterns of consumption and production, as well as incentives to redirect investment flows. Given the fundamental changes required to achieve low carbon development, mitigation actions needs to be integrated with broader development goals and plans. Low Emission Development Strategies (LEDS) can help to outline the intended overall economic, energy, and emissions trajectory for a country, set clear targets, and identify and prioritize policy interventions that contribute to national development goals. EU and UNDP Low Emission Capacity Building Programme website
- A LEDS is a national, high-level, comprehensive, long-term strategy, which aims at decoupling economic growth and social development from greenhouse-gas (GHG) emissions. It provides long-term guidance for daily policy decisions. In order to be effective and relevant, a LEDS should build upon and influence existing national strategies and processes, such as national development plans, poverty reduction strategies, sectoral strategies, etc. GIZ (2012). LEDS Factsheet
- The form, scope and content of LEDS vary from country to country. Some countries have developed self-standing national low-carbon or green economy strategies. For example, Ethiopia has embarked on the development of a Climate-Resilient Green Economy (CRGE) Strategy addressing both climate change adaptation and mitigation objectives. The strategy builds on the country’s five-year Growth and Transformation Plan (2010/11 – 2014/15). Other countries have integrated green/low-carbon considerations directly in their national development plans. For example, South Korea in 2009 enacted a Framework Act on Low Carbon Green Growth, the first law of its kind in the world, and released a National Strategy for Green Growth and a Five-Year Plan for Green Growth. Under the Five-Year Plan, Korea is investing annually about 2 % of its GDP in the field of green growth. UNDP website UNCSD website
- There is no internationally agreed definition of what a LEDS includes. According to the German Development Cooperation (GIZ), LEDS comprise most or all of the following elements: A long-term strategic vision based on national development priorities, global agreements and scientific projections Baseline GHG emissions analysis and projections under a “business as usual” scenario Prioritization of key mitigation sectors and measures (according to e.g. abatement potential, costs, co-benefits, feasibility, timeframe of implementation, socio-economic and environmental impacts, synergies with existing national strategies and policies, etc) Identification of policies, measures and definition of targets Further information: The approach for developing a LEDS depends on the national framework conditions. For example, some rainforest countries may focus primarily on the forestry and agriculture sectors and include adaptation aspects, as these sectors are very vulnerable to climate change. Some newly industrializing countries may have the resources and data available to perform a comprehensive analysis of all sectors. Mitigation Partnership website GIZ (2012). LEDS Factsheet
- An essential element of a LEDS is the identification of concrete policy measures. Policy-makers have the choice between various instruments to promote mitigation and low carbon development. Market based mechanisms, such as emissions trading schemes, establish an overall level of emissions allowed, and then let the open market determine the price. Financial incentives to promote mitigation include, for example, subsidies for renewable energies or access to capital for clean technology start-ups. Fiscal instruments, such as carbon taxes, follow the “polluter pays” principle. That means they charge producers or consumers at the point that they are responsible for the creation of a emissions. Other instruments include support for research and development of low carbon development technologies or the establishment of environmental standards (e.g. on energy efficiency). Investing in appropriate skills development, e.g training workers in the renewable energy sector, can also support the implementation of a low carbon development strategy.
- LEDS do not only include national policy instruments, but can promote a wide range of mitigation actions, including individual mitigation projects or sectoral initiatives. This spectrum of actions is summarized under the term “Nationally Appropriate Mitigation Actions (NAMAs)”. The relationship between LEDS and NAMAs can be top-down or bottom-up. For example, a LEDS might be developed beginning from an overall policy objective and emission reduction goal of the country, before moving on to identifying NAMAs in various sectors. This approach usually relies upon the results of macro-economic modeling. Or it might be bottom-up, with emission reduction options/NAMAs in various sectors identified and prioritised first, which are then integrated within an overall emission reduction goal of a LEDS. EU and UNDP Low Emission Capacity Building Programme website
- Mitigation actions are already underway in countries all over the world. Several databases have been created to compile information on NAMA development and implementation and to help facilitate exchange of information and knowledge sharing. Thus, decision-makers can learn from other countries experiences and gain insights into how mitigation activities can support the low-carbon development of their countries. The slide shows a selection of NAMAs underway in different regions of the world.
- This section presents seven sectors which have a particularly high mitigation potential (including energy, transport, buildings, industry, agriculture, forestry, and waste management). For each of these sectors, examples of specific mitigation measures that can be undertaken are being provided.
- The graph illustrates the mitigation potential of different sectors, as identified by the IPCC. This categorization is now largely recognized and applied on national and international levels. The percentages indicate the share of global GHG emissions in 2010 per sector. UNEP (2012). The Emissions Gap Report, p11
- The energy sector poses particular challenges in the context of low carbon development due to its size and potential transformational effects for the development of other sectors. A wide variety of mitigation options can be applied in the energy sector. Renewable energies can make a major contribution to reducing emission levels. Changes in energy production patterns need to be supplemented with improvements in energy distribution systems (e.g. improved power grids) to avoid inefficient use of energy resources. New technologies for climate change mitigation, include for example Carbon Capture and Storage (CCS). CCS allows depositing carbon dioxide from large point sources (such as fossil fuel power plants) in an underground storage site, preventing it from entering the atmosphere. Combined heat and power (CHP) allows the use of a heat engine or power station to simultaneously generate electricity and useful heat.
- From 2005 to 2009, an average growth rate of 17% per year was observed in the domestic demand for electricity in Bhutan. Wider rural electrification coverage is expected to make the domestic demand supply balance even tighter. In view of the rising demand for electricity and increasing reliance on hydropower as an energy source, it was deemed critical to broaden the energy mix by means of harnessing other forms of clean renewable energy sources. The new Renewable Energy Policy seeks to diversify the energy supply base through wind, solar, biomass, and micro hydropower. Specific options which Bhutan has started to explore and implementing (with the help of international partners, such as the Asian Development Bank) include: on-grid rural electrification sourced from hydropower, off-grid rural electrification sourced from solar power, establishment and grid-connection of pilot wind power generation mills, a pilot program to promote domestic biogas plants.

- The main challenges for the transport sector include high consumption of liquid fossil fuels, growing emissions, as well as chronic traffic congestion in many of the world’s urban areas. Key mitigation technologies developed in the transport sector focus on the design of more fuel efficient vehicles and the use of alternative energy sources such as biofuels. Policy interventions such as more affordable urban public transport and more bicycle lanes can also contribute to mitigating the impacts of the transport sector. In addition, consumer behaviour plays an important role, for example in terms of purchasing smaller vehicles, or taking the bus, bike or train instead of a personal car.
- The TransMilenio Bus Rapid Transit (BRT) system of Bogotá, Colombia reduces emissions by facilitating the use of public transportation. It also has co-benefits for the urban poor: as a result of the BRT the traveling time of the lowest income groups which live in the city periphery is now considerably shorter, resulting in increased labour productivity and access to work, services and education.

- How we design and build our homes, offices, commercial and industrial buildings can make a big contribution to reducing carbon emissions. In developed countries, opportunities for reducing emissions from the building sector are found mainly in retrofitting existing buildings (e.g. improved insulation, more efficient light bulbs, etc). For the majority of developing countries, which have a significant housing deficit, the greatest potential to reduce energy demand comes from a new generation of green buildings with more efficient design, less energy intensive materials, and higher performance standards.
- Sofia, like many cities in Eastern Europe, is surrounded by sprawling prefabricated housing estates, built during the socialist period. With soaring energy prices, incentives are high to improve the energy efficiency of such buildings. Energy bills can be cut by as much as 50 percent in some cases, and hence the money invested in renovations can be recouped in a couple of years. With half of Sofia's GHG emissions coming from buildings, there are great opportunities for lowering the city’s carbon footprint, while at the same time improving the living conditions of citizens and creating employment.
- Industry consists of a vast array of activities involving thousands of different processes that are often site-specific in design. Whereas the buildings and transportation sectors can utilize a limited number of energy conservation measures that may be widely applied, the industrial sector requires more of a focus on options in specific industries. Generic technologies that cut across industries represent only part of the full range of opportunities, and even these generic technologies are typically customized for particular applications. Generally, low-carbon measures in the industrial sector include more efficient use of energy and better use of materials and recycling. Thereby, the greatest increases in the efficiency of energy and materials use often do not come from direct efforts to reduce consumption, but rather from pursuing other goals such as improved product quality and lower production costs.

- Erel Cement is a cement producer in Darkhan, Mongolia and produces approximately 80,000 tons cement per year. The dust emission removal and control system at the gypsum feeding point to the cement mill was poor, an dust emissions were only visually monitored. Twelve electro motors were installed at the strew conveyors and the dust control system was better sealed off. This resulted in a net GHG emission reduction of 11,007 tons CO2 per year.

- Mitigation of GHG emissions in the agriculture sector can be achieved through reducing/avoiding emissions or by creating carbon sinks. To reduce emissions from farming systems, several means are available. For example, in crop and feed production, the use of inorganic fertilizer can be optimized, or in some cases, replaced by organic fertilizers. In terms of carbon sinks also different approaches exist, such as increasing biomass (and carbon) by incorporating trees and bushes to farming systems. Great potential also lies in increasing the carbon content of soils. Through the restoration of degraded soils, especially in vast grassland and pasture areas, by regulating animal numbers and pasture improvement, the soil carbon sequestration rate is improved.
- The agriculture sector faces complicated and intertwined challenges. It needs to ensure food security, adapt to the impacts of climate change, and mitigate its contribution to GHGs emissions. Climate-smart agriculture refers to “agriculture that sustainably increases productivity, resilience (adaptation), reduces/removes greenhouse gases (mitigation) and enhances achievement of national food security and development goals”. FAO’s website dedicated to climate-smart agriculture features a number of production services that are already being used by farmers and food producers to address these intertwined challenges.
- Reducing deforestation, establishing a forest where there was no forest (afforestation) or restocking depleted forests (reforestation) are some of the prime mitigation options that can be applied in the forestry sector. Forest management plays an important role in reducing deforestation and eliminating illegal logging. At policy level the promotion of voluntary certification schemes for sustainable forest management can contribute to ensuring that trees, an important carbon sink, are managed in a sustainable manner.
- Indonesia’s forest land comprises 60 % of the country’s land area, which makes it the third largest area of tropical rainforest in the world. The Indonesian rainforests are also among the world’s richest in terms of biodiversity and cover a significant proportion of the planet’s tropical deep peat. Indonesia’s forest is therefore important not only for the national economy and local livelihoods, but also for the global environment. The Government of Indonesia estimates that, for each year between 2003 and 2006, around 1.17 million ha of forest was cleared or degraded. Since 2009 UN-REDD has been working with relevant government agencies, NGOs, academics and the private sector at the national level and in the pilot province, Central Sulawesi. The Programme has supported the development of several decrees. A methodology for Reference Emission Level was developed and a National Forest Inventory database has been set up.
- Waste generates methane emissions. By applying mitigation technologies such as landfill methane recovery a dual purpose is fulfilled: not only is less methane emitted into the atmosphere but methane can also be used to generate electricity. Other mitigation technologies that can be used are waste incineration with energy recovery or the composting of organic waste, a method that can be applied by households.
- Landfill sites, with wastes undergoing a methanogenic stage of biodecomposition, produce large volumes of landfill gas (LFG) typically containing some 40-60% methane. At Marianhill Landfill site, Durban, South Africa, a methane capture system converts the methane into electrical energy that is then fed into the national electricity grid. This method of electricity production entails higher costs and is not competitive as compared with other options in South Africa. However, the project is made possible via carbon financing, channelled through the World Bank’s Prototype Carbon Fund (PCF), a Public Private Partnership with participants from several countries worldwide. The Marianhill Landfill site is the country’s first Clean Development Mechanism (CDM) project.
- This section presents an overview of the different ways international support is provided for mitigation activities. It first presents the financial mechanisms found in the Kyoto Protocol and the recently negotiated New Market Mechanism (NMM). It then provides a summary of selected UN agencies and programmes that provide technical of financial support for mitigation.
- Various international instruments provide assistance to countries in reaching their emission reduction targets. Under the Kyoto Protocol three flexible market mechanisms were established, including the Clean Development Mechanism (CDM), Joint Implementation (JI) and Emission Trading. A New Market Mechanism (NMM) to complement the flexible market mechanisms is under negotiations. Some countries/regions have established their own carbon offset and trading schemes, such as the European Union Emissions Trading System (EU – ETS) , the New Zealand Emissions Trading Scheme (NZ ETS), Regional Greenhouse Gas Initiative (RGGI) in the US and the Tokyo Metropolitan Emissions Trading Scheme. In addition, non-market mechanisms exist, which in principle include all mitigation actions as long as these are not considered as market-based approaches.
- The three mechanisms for emission reductions established under the Kyoto Protocol create flexibility for Annex I Parties to meet their obligations under the Protocol. Joint Implementation (JI), for example, allows Annex I Parties to implement emission reduction projects in other Annex I countries as an alternative to reducing emissions domestically. The Clean Development Mechanism (CDM) on the other hand allows Annex I Parties to invest in sustainable development projects in non-Annex I countries. The third mechanism, emission trading, gives Annex I Parties the possibility to acquire carbon credits, so called Assigned Amount Units (AAU), from other Annex I Parties that have spare AAUs because of emission reductions beyond their Kyoto commitment. The price for carbon credits is determined by the market. For more detailed information about the Kyoto Protocol see Module 2
- Further mitigation efforts are necessary globally to stay below a 2°C increase in global average temperature. New carbon market mechanisms could contribute to the needed efforts in a cost-effective manner, including in developing countries. In this context some countries have proposed scaled-up market mechanisms, based on policies or sector-wide reductions (instead of project based emission reductions). During COP 17, Durban 2011, it was decided by Parties to the Convention that a international New Market Mechanism (NMM) is to be established to complement the CDM and JI. Further information: While the details of the new mechanism are still under negotiation a few parameters have been set out: The mechanism will operate under the guidance and authority of the Conference of the Parties (COP). Participation in the mechanism will be voluntary. The mechanism should include “standards that deliver real, permanent, additional, and verified mitigation outcomes, avoid double counting of effort and achieve a net decrease and/or avoidance of greenhouse gas emissions”.

- Emission trading scheme? Cap and trade? What do these words mean? And how does it all contribute to reduced emissions of greenhouse gases? This animation shows how the scheme works. By the Norwegian Ministry of Environment.
- Various work programmes and initiatives have been developed to support countries in meeting their Convention obligations. The Nairobi Framework aims to assist countries with CDM implementation and to enable countries to identify, develop, submit and process CDM projects. The UN REDD Program seeks to create a financial value for the carbon that is stored in trees. It offers incentives for developing countries to reduce emissions from forested lands and to invest in low-carbon development paths that are sustainable. At COP 16, Cancun 2010, Parties decided to establish a registry where NAMAs seeking international support (demand) can be matched with finance, technology and capacity-building support (supply).
