National Climate Targets Classifier - Climate Policy Radar

A multi-label text-classifier trained on the National Climate Targets dataset by Climate Policy Radar.

Using the climatebert/distilroberta-base-climate-f model as a starting point, this classifier is trained on the ClimatePolicyRadar/national-climate-targets dataset to predict Net Zero ("NZT") , "Reduction" and "Other" targets in a multi-label setting. The training data is an expert annotated subset of national laws, policies and UNFCCC submissions.

For more information on the annotation methodology and classifier training see our paper.

Getting started

from transformers import AutoModelForSequenceClassification, AutoTokenizer


model_name = "ClimatePolicyRadar/national-climate-targets"
example = "The Net Zero Strategy, published in October 2021, was the first "\
    "document of its kind for a major economy. It set out the government’s "\
    "vision for a market-led, technology-driven transition to decarbonise "\
    "the UK economy and reach net zero by 2050."


model = AutoModelForSequenceClassification.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)

# using sigmoid because the model is multi-label
pipe = pipeline("text-classification", model=model, tokenizer=tokenizer, function_to_apply="sigmoid")


pipe(example, padding=True, truncation=True, return_all_scores=True)

>>> [[{'label': 'NZT', 'score': 0.9142044186592102},
  {'label': 'Reduction', 'score': 0.04552844911813736},
  {'label': 'Other', 'score': 0.07590094953775406}]]
