ENVIRONMENTAL IMPACTS OF THE CCU̶ POTENTIAL CO 2 MARKET
the potential anthropogenic CO• 2 supply could reach over 12.7 Gt/y
the current global annual CO• 2 consumption is estimated to be 222.5 to 299 Mt CO2/y
the potential CO• 2 demand in the near-term of up to 10 years is estimated to be ≤300 Mt/y, and 650-700 Mt/y by 2050

ENVIRONMENTAL IMPACTS OF THE CCU̶ CCU’S ROLE IN CLIMATE CHANGE MITIGATION
CCU is the key element to transform the current linear economy to a •circular carbon economy
CCU enables the move of chemical and energy industry towards low• -carbon production that reduce CO2 emissions sustainably
CCU presents expanded options and reduced costs for climate change •mitigation
CCU can help to • accelerate the uptake of CCS by offsetting the costs

KEY MESSAGES
CCU provides routs to use CO• 2 to substitute fossil fuels and introduce renewable energy into the production processes, allowing transformation of manufacturing industry to new sustainable production systems at minimal costs
CCU should form part of an overall strategy to mitigate climate change, •along with improved efficiency, curtailed consumption, expansion of renewable energy use and CCS
CCU technologies are rapidly advancing with some are already in •commercial operation and more are emerging in the commercial market. In a short-to-medium-term, CCU will continue its progression, especially in areas that are technologically more advanced such as CO2-derived polymers, CO2 carbonation and methanol production
In the long term, CCU will become a key element in a circular carbon •economy with sustainable, low-carbon chemical and energy production
