I think the following would be a great start:

- Stop destroying forests (such as Amazon) which are a huge carbon sink for cows which are a carbon source.

- Build more buildings out of wood (wood buildings are carbon sinks) instead of concrete (carbon source)

- All building lumber should be self-sustaining (i.e. replant trees you used to build)

- Stop over fishing and allow oceans to grow unchecked (all living things sequester carbon while they are alive... the ocean is potentially the biggest carbon sink of all and could have several magnitudes more fish and plankton life sequestering billions of tons of carbon)

- Supplement all of the above with man-made carbon sequestration tech
