I’ve been trying to limit my flights for 3 years now. I still fly about once per year (to do field work or to attend major conferences) but I’m planning to cut back even further. I’m also encouraging my colleagues to fly less. The major challenge (as a New Zealand scientist) is that we are surrounded by ocean and so it’s very hard to find an alternative way to visit international labs or conferences…there are no trains I can take to travel to Europe or North America! I’m actively exploring virtual conference options and trying to use internet video calls to keep collaborations going. As a senior scientist this works ok, but for younger New Zealand scientists this is very difficult, as they need to forge links around the world. In the long run, we may need to accept more limited collaborations in science to help protect the environment.
