Atmospheric concentrations of CO₂e are rising due to increasing anthropogenic emissions. Unchecked, rising concentrations of CO₂e in the atmosphere will lead to catastrophic climate change.
Public electricity and heating in Annex I countries accounted for over 6.68 billion tons of CO₂e emissions annually in 2007.
Transport is responsible for approximately 20% of global anthropogenic emissions, or more than 4.63 billion tons of CO₂e annually. Source: UNFCCC, 2009.
Buildings are responsible for an estimated 1.45 billion tons of CO₂e in Annex I nations and over 20% of global anthropogenic emissions annually. Source: UNFCCC, 2009.
Annex I industry emissions are over 1.3 billion tons of CO₂e annually. Global industry emissions account for approximately 24% of annual anthropogenic emissions. Source: UNFCCC, 2009.
Emisisons from agriculture in Annex I countries totaled more than 1.43 billion in 2007 CO₂e emissions.
The EIA estimates that 2006 energy-related emissions from non-OECD countries accounted for approximately 30%, of global anthropogenic CO₂e emissions, or 15.4 billion tons. Source: EIA, 2009.
Biochar could potentially remove over 1 billion tons of CO₂e annually. In general, carbon management solutions could remove billions of tons of CO₂e from the atmosphere annually.
Industrial energy use accounts for 37% of global energy use and is the source of more than 10 billion tons of CO2e emissions annually, or 20% of anthropogenic emissions. Industrial energy use has grown about 2% each year since 1975 according to the IPCC and is projected to continue increasing under business-as-usual scenarios.

At a 2% annual growth rate, energy-related emissions from industry will reach 18.1 billion tons of CO2e in 2020 and contribute significantly to rising concentrations of atmospheric CO2e that lead to catastrophic global climate change.
About half of current industrial energy consumption can be attributed to the iron, steel, and chemical production sectors. Much of the growth in industrial energy demand has come from emerging economies. China accounts for about 80% of the growth in the last twenty five years and is the world’s largest producer of iron, steel, ammonia, and cement, according to IEA 2007 data.
Energy is a substantial part of industry costs, which makes efficiency technologies attractive to businesses. Harvesting of waste heat for energy and recycling of materials, for instance, can both improve the bottom line while reducing energy consumption and associated emissions. In many cases steps taken to reduce industrial energy use can be achieved at a negative cost.

There are a number of approaches to reducing industrial energy use:
Combined, the IEA estimates mitigation potential for CO2e from these measures to be approximately 5.4 billion tons annually by 2050. The potential to achieve these reductions in a shorter timeframe, by 2020, will depend on the ability to accelerate adoption of efficiency measures and low-carbon technology in these sectors.
Market-based Approaches
Energy savings are available in almost all segments but involve an upfront investment; hence one of the biggest challenges to be addressed is financing. The global recession has made financing more difficult but this is likely a short-term hurdle. As financial institutions look for new classes of investments, industrial efficiency could be a promising if positioned correctly.
The industrial sector has experienced limited innovation around energy efficiency and low-carbon technologies, in comparison to the energy sector, and represents a nascent market. Lack of information is a market-inhibitor. Successful efficiency projects need to be showcased and opportunities for savings highlighted.
Also, without guarantees, such as those offered by Energy Services Companies (ESCOs), industries may understandably be nervous about investments in energy efficiency. Examples can help address this; guarantees may be required in some cases.
