The most common method of carbon capture is called point source capture and it's  actually been around since the 1970s.

最常见的碳捕获方法称为点源捕获，实际上自 1970 年代就已存在。

It is critical that governments, both local and national, as well as companies, assess the potential for carbon capture at a local level, start to capture the cheapest sources of CO2 and build up the network from there.

至关重要的是，地方和国家政府以及公司都应评估地方层面的碳捕获潜力，开始捕获最便宜的 CO2 来源并从那里建立网络。
