Task: Sentence-level classification — determine if a sentence is Sustainability-Related (Yes / No).
Base model: roberta-base, fine-tuned on a labeled ESG corpus from the Green-Guard dataset.
Repository: GitHub → Green-Guard Project

🚀 Quick Inference

You can load and run the model directly:

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

model_id = "salitahir/roberta-esg-relevance-green-guard-v1"
tok = AutoTokenizer.from_pretrained(model_id)
mod = AutoModelForSequenceClassification.from_pretrained(model_id).eval()

text = "We reduced Scope 2 emissions by 24% in 2024."
inputs = tok(text, return_tensors="pt", truncation=True)
pred = torch.softmax(mod(**inputs).logits, dim=-1)
label_id = pred.argmax(-1).item()
label = mod.config.id2label[str(label_id)]
print(label, float(pred[0][label_id]))

✅ Expected output:

Yes 0.94

🧠 Intended Use

This model acts as Stage 1 in the two-stage Green-Guard ESG classifier, filtering sustainability-related sentences before ESG-type categorization.
