The Climate Intelligence Framework - Build climate-aware applications with AI-driven orchestration

GreenLang - The Climate Intelligence Framework

Build climate-intelligent applications with the power of AI-driven orchestration. The LangChain of Climate Intelligence is here.

What is GreenLang?

GreenLang is a developer-first Climate Intelligence Framework that brings LangChain-style modularity to sustainable computing. It provides a comprehensive toolkit for building climate-aware applications across industries - from smart buildings and HVAC systems to industrial processes and renewable energy optimization.

Key Features

• AI-Powered Climate Intelligence: Intelligent agents for automated emissions analysis and optimization recommendations
• Modular Architecture: Composable packs and pipelines for rapid development
• Multi-Industry Support: Buildings, HVAC, solar thermal, cement, and expanding
• Global Coverage: Localized emission factors for 12+ major economies
• Developer-First Design: Clean CLI, Python SDK, and YAML workflows
• Type-Safe APIs: 100% typed public interfaces with strict validation
• Explainable Results: Transparent calculations with full audit trails
• Real-World Data: Integration with industry-standard datasets and benchmarks

Installation

# Basic installation
pip install greenlang-cli

# With analytics capabilities
pip install greenlang-cli[analytics]

# Full feature set
pip install greenlang-cli[full]

# Development environment
pip install greenlang-cli[dev]

Quick Start

CLI Usage

# Initialize a new GreenLang project
gl init my-climate-app

# Create a new pack for emissions calculation
gl pack new building-emissions

# Run emissions analysis
gl calc --building office_complex.json

# Analyze with recommendations
gl analyze results.json --format detailed

# Execute a pipeline
gl pipeline run decarbonization.yaml

Python SDK

from greenlang import GreenLang
from greenlang.models import Building, EmissionFactors
from greenlang.agents import BuildingAgent, HVACOptimizer

# Initialize GreenLang
gl = GreenLang()

# Create a building model
building = Building(
    name="Tech Campus A",
    area_m2=50000,
    location="San Francisco",
    building_type="office"
)

# Calculate emissions
agent = BuildingAgent()
results = agent.calculate_emissions(
    building=building,
    energy_data=energy_consumption,
    emission_factors=EmissionFactors.get_region("US-CA")
)

# Get optimization recommendations
optimizer = HVACOptimizer()
recommendations = optimizer.optimize(
    building=building,
    current_emissions=results.total_emissions,
    target_reduction=0.30  # 30% reduction target
)

print(f"Current emissions: {results.total_emissions} tCO2e/year")
print(f"Potential savings: ${recommendations.estimated_savings:,.2f}")
