During the last year, travel to international meetings and conferences has slowly started to pick up again. While we learned a lot about how to interact virtually in the two years of the COVID pandemic, we also learned the value of personal interactions. The challenge now is to balance our responsibility to keep carbon emissions as low as possible with the importance of building professional relationships. The WCRP Guidelines on Reducing Carbon Emissions from Travel aims to reduce carbon emissions from WCRP-related travel, while also helping the community to think strategically about how to deliver meetings in ways that reduce the carbon footprint of the Programme.
