Our approach

Origins


The UN’s journey towards climate neutrality began on 5 June 2007 when UN Secretary-General Ban Ki-moon publicly called on all UN agencies, funds and programmes to ‘go green’ and become climate neutral. Find out about the origins of the UN’s work to create a more sustainable UN, who is involved and how the work is being coordinated.

Measuring and reporting greenhouse gas emissions 


A process for measuring and reporting the UN’s greenhouse gas emissions is now in place. Find out what the UN Greenhouse Gas inventory covers and how the UN's greenhouse gas emissions are calculated. In 2016, for the first time, the UN also reported data on waste.

Measuring and reporting waste


In 2016, for the first time, the UN provided data on waste management for a number of UN entities.

Reducing our impacts


In addition to the work that’s going on within individual UN organizations, there’s also a considerable amount of activity at the UN System level to reduce the UN’s environmental impacts.

Offsetting


Whilst the UN continues to do all it can to reduce its emissions, some are unavoidable. Where emissions are unavoidable organizations are exploring the feasibility of offsetting.
