Over the past few years, market conditions have changed so dramatically that today, regardless of their products or services, every company is also doing business in the environmental field. Spurred on by the real impacts of climate change, many consumers are now demanding environmental action from corporations and preferring to buy products marketed as green. Many companies therefore market their products as "net zero" or "carbon neutral" - and commit to becoming "net zero" as a business by a certain date. To support these pledges, companies often purchase carbon credits from voluntary carbon markets to voluntarily offset or mitigate their carbon emissions.
