Model Card for netzero-reduction

Model Description

Based on this paper, this is the fine-tuned ClimateBERT language model with a classification head for detecting sentences that are either related to emission net zero or reduction targets. We use the climatebert/distilroberta-base-climate-f language model as a starting point and fine-tuned it on our human-annotated dataset.

How to Get Started With the Model

You can use the model with a pipeline for text classification:

IMPORTANT REMARK: It is highly recommended to use a prior classification step before applying ClimateBERT-NetZero. Establish a climate context with climatebert/distilroberta-base-climate-detector for paragraphs or ESGBERT/EnvironmentalBERT-environmental for sentences and then label the data with ClimateBERT-NetZero.

from transformers import AutoModelForSequenceClassification, AutoTokenizer, pipeline
from transformers.pipelines.pt_utils import KeyDataset
import datasets
from tqdm.auto import tqdm
 
dataset_name = "climatebert/climate_detection"
tokenizer_name = "climatebert/distilroberta-base-climate-f"
model_name = "climatebert/netzero-reduction"
 
# If you want to use your own data, simply load them as 🤗 Datasets dataset, see https://huggingface.co/docs/datasets/loading
dataset = datasets.load_dataset(dataset_name, split="test")
 
model = AutoModelForSequenceClassification.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(tokenizer_name, max_len=512)
 
pipe = pipeline("text-classification", model=model, tokenizer=tokenizer, device=0)
 
# See https://huggingface.co/docs/transformers/main_classes/pipelines#transformers.pipeline
for i, out in enumerate(tqdm(pipe(KeyDataset(dataset, "text"), padding=True, truncation=True))):
  print(dataset["text"][i])
  print(out)
