UN Decarbonisation Task Team
The UN Decarbonisation Task Team (DTT) is a dedicated platform coordinating UN agencies' efforts to reduce their energy-related emissions and advance sustainable energy solutions across humanitarian, development, and peace operations.
It drives progress in the decarbonisation of on-site energy generation within UN operations and promotes sustainable energy solutions in line with the target of a 45% reduction in UN greenhouse gas emissions by 2030, as outlined in the UN Sustainability Strategy 2020–2030.
Based on the 2025 Greening the Blue report, 44% of the UN systems reported emissions originated from the operation of facilities; out of that total, 46.6% came from Generators. Additionally, the humanitarian sector spends over $100 million annually on diesel generators and fuel to power field operations, generating over 194,000 tonnes of CO2e. Reducing these emissions through investment in cost-effective renewable energy supply and energy efficiency measures is essential for delivering on the sector’s commitments to furthering global climate action and protecting the communities it serves, many of which are living on the front lines of climate change.
