One of the biggest mental blocks people have in regards to climate change, is not being able to separate carbon emissions from general environmental angst. In short there's nothing stopping us from converting our civilization to being carbon neutral, but our very existence will always have some environmental impact there is no getting past that. Aviation in particular will be carbon neutral either through synthetic hydrocarbon fuel (Prometheus Terraform), new hydrogen engines, or a network of shorter hop flights with battery powered aircraft (Eviation). In fact it may turn out to be one of the easier industries convert to carbon neutral. If you're really worried, you can work on one of these. If you don't have the skills or the time there's always politics, since you approaches like this will face regulatory and political hurdles that are at least as big as the technical hurdles.
