As an approved third-party verifier of CBI, CTI will provide professional services including pre-issuance verification and post-issuance continuous information disclosure and verification for climate bond issuers.

While setting the carbon targets, enterprises must consider the background of the global climate crisis, and also ensure the scientific and ambitious level of the objective, that is, to set emission reduction target that meets the requirements of the Paris Agreement or the United Nations Intergovernmental Panel on Climate Change (IPCC) to control the global temperature rise within 2℃ or 1.5℃.

Product carbon footprint is defined as the various Greenhouse Gas (GHG) emissions of a product in its whole life cycle, that is, the GHG emissions in all stages from raw materials to production, distribution, use and disposal/reuse, expressed as CO₂e. The process of measuring the carbon footprint of various products in their whole life cycle can help companies to collect the information they need, so that they can: reduce various GHG emissions, identify opportunities for cost saving, integrate the impact of emissions into decisions on supply, material, product design, manufacturing and other processes, and present their leadership in environmental responsibility or corporate responsibility in order to meet the needs of customers for carbon footprint information.

Since CTI Certification was qualified as a third-party auditing agency for CCER projects after being approved by the National Development and Reform Commission in August 2014, with the service concept of "Customer-centered", and with the efforts of a group of experienced, rigorous and efficient auditors with high communication abilities, the auditing of low-carbon emission reduction projects of CTI Certification has obtained high reputation in the industry in recent years.

Under the framework of the United Nations Framework Convention on Climate Change, the Kyoto Protocol introduces three market-based emission reduction mechanisms. CDM is one of the most effective mechanisms. Its theoretical basis comes from the idea of "tradable emission permits", which is commonly known as "carbon trading". CTI (Centre Testing International Group Co., Ltd) Certification is a Designated Operational Entity (DOE) approved by the Executive Committee (EB) of the United Nations Clean Development Mechanism (CDM). It is qualified to carry out the certification and verification of CDM projects.

Energy audit is a kind of activity that the audit unit will check, verify, analyze and evaluate the energy utilization process of enterprises and other energy using units according to the relevant national energy saving regulations and standards. It is the effective means and method for the government to strengthen the scientific management of enterprise energy and to save energy, It has played a strong role in supervision and management.

Carbon neutrality, also known as "Net Zero Emission", refers to the carbon emission necessary for human economic and social activities, which is captured, utilized or stored by forest carbon sink and other artificial technology or engineering means, so that the net increase of greenhouse gas emitted into the atmosphere is zero. CTI Certification takes sustainable development business such as green, low-carbon and energy efficiency services as the key direction of its future development, and has been qualified for a variety of greenhouse gas project auditing and energy-saving services at both home and abroad
