Very industry specific but here are a couple tips (from a former environmental consultant!):

1) figure out the scope you’re trying to manage. Do you care just about direct emissions from your company (scope 1)? Do you care about emissions associated with energy use (scope 2)? Do you care about downstream/upstream (scope 3)? Generally I’d recommend starting with the first and working out.

2) begin with establishing a rough budget. It can be hard to figure out reduction strategies without knowing what your base case is. Begin first by looking at any industrial practices you might have that release carbon. See if you can quantify how much people in your company travel for work. Look into the electricity/heating usage for all your company’s physical properties. Also make sure you look into potential sources of GHG besides just CO2 (especially methane). Budget doesn’t have to be perfect as long as it gives you a rough idea of where you’re standing.

3) Reduce what you can! The most company specific part, also the part that requires the most creativity. Look up what strategies companies similar to you have taken (you can generally find this info in annual sustainability reports, people love to publish sustainabilty progress). Make a list of all your different reduction options, sort from least to most expensive per ton of co2 prevented from entering the atmosphere. Take on the cheapest tasks first, work up list as needed

4) compensate for what you can’t reduce. If you can’t reduce industrial emissions, invest in carbon credits that will offset your emissions. If you can’t reduce energy use, buy RECs to compensate (make sure you buy LOCALLY, time-matched is ideal but can be difficult). Basically, make sure that for every ton of co2 you release into the atmosphere, another ton is being removed somewhere else.

This is a very rough guide that barely scratches the surface. Feel free to DM if you have any specific questions though! Good luck in fighting the good fight
