[0003] At present, the calculation of carbon neutrality of listed companies mainly measures the greenhouse gas emissions of listed companies. Professional carbon monitoring agencies measure the company's fossil fuel combustion CO2 emissions. 2 Emissions, Carbonate Use Process CO 2 Discharge, wastewater anaerobic treatment CH 4 Emissions, CH 4 Recovery and destruction amount, CO 2 The CO2 emissions implied by the amount of recycling, net purchased electricity and heat, and the important role of listed companies in carbon-neutral development, the evaluation methods of investment opportunities and development potential are missing

Embodiment
[0050] The present invention will be further described in detail below in conjunction with the examples, and the specific examples described here are only for explaining the present invention, rather than limiting the present invention.
[0051] A specific example of a carbon neutral evaluation method for a listed company:
[0052] The first choice is to collect the underlying data sources of listed companies, including company annual reports, social responsibility reports, announcements, various information provider databases, public disclosure news, official authoritative websites, and calculate the underlying scores based on the underlying data sources, using natural language processing (NLP) technology Identify alternative data, alternative data through keyword matching technology, keywords such as carbon emissions, energy-saving equipment, etc., to score some indicators of the underlying data source, and identify whether listed companies are classified into hydropower, pho...

The invention relates to the technical field of carbon neutralization evaluation, in particular to a listed company carbon neutralization evaluation method, which comprises the following steps of: collecting a bottom layer data source, calculating a bottom layer index score according to the bottom layer data source, weighting different scores by using an analytic hierarchy process according to the bottom layer index score to obtain a fourth-level index score, and according to the fourth-level index score, weighting different scores to obtain a third-level index score by adopting an analytic hierarchy process, and calculating a second-level index score and a first-level index score according to the weight in sequence, compared with the prior art, collecting detailed traditional data and alternative data of the listed company by using a natural language processing technology, a pressure test method and an AHP (Analytic Hierarchy Process); a four-level scoring index system is set, weighted scores of all levels are calculated from bottom to top, and the key effect of listed companies in the carbon neutralization field is evaluated.
Description
technical field [0001] The invention relates to the technical field of carbon neutrality evaluation, in particular to a carbon neutrality evaluation method for listed companies. Background technique [0002] Carbon neutrality refers to offsetting the carbon dioxide emissions generated by human activities through afforestation, greening, environmental protection travel, energy saving and emission reduction within a certain period of time, so as to reduce the net carbon dioxide emissions to zero. In the process of achieving the goal of "carbon neutrality", it will promote the revolution of energy production and consumption, the establishment of a green industrial system and the low-carbon development of urbanization, gradually reverse the situation of rapid growth of greenhouse gas emissions, and effectively promote high-quality economic development and ecological protection. The synergy of high-level environmental protection improves the efficiency and effectiveness of econom...
