Reduce
Once targets have been set the next step is to achieve them – and this should be done through the most cost effective mix of internal and external emission reductions.
Internal reductions are those that take place within the boundary of the ‘thing’ (company, product, service or business process) that is being measured. External reductions are those that take place in projects outside the boundary of the thing that is being measured (known as ‘carbon offsets’). These external emissions reductions are packaged up and traded as carbon credits to ‘offset’ emissions.
The dilemma that many organisations face is how to balance internal and external reductions. Should they, for example, seek to reduce emissions ‘as far as possible’ internally before considering offsetting? The problem with this approach is one of time and material impact: you cannot change overnight the profile of a car fleet or a manufacturing process; with substantial commitment, many organisations could see carbon reductions of 20% in the medium term. But scientists are calling for 80% reductions, now.
Carbon offsetting enables an immediate reduction of CO2 emissions to net zero, and then time to put in place effective strategies for cuts to internal emissions.
One of the values of using external reductions or carbon credits within your strategy is that they provide a benchmark against which to evaluate alternative internal reduction opportunities. For example, if the cost of carbon credits is £10/tCO2, then internal emissions reduction measures which cost more than this – based on any capital investment needed, annual cost savings achieved (e.g. in the case of energy efficiency measures) and the lifetime of the measure – should be considered carefully before the investment is made.
Taking this systematic approach will ensure that the most cost-effective combination of internal and external emission reduction projects are selected to deliver on the agreed target.
The quality of carbon credits selected is vitally important if they are to be viewed as a credible part of any strategy. A number of standards have emerged lasting recent years as leaders: The Clean Development Mechanism of the Kyoto Protocol (CDM); The Voluntary Carbon Standard (VCS); the Gold Standard. Credits certified to one of these standards will be viewed positively by stakeholders. Clients must also ensure that the offset provider is willing and able to guarantee delivery of any credits bought – actual project performance can vary considerably from plan and clients will want offset providers to be responsible for making good any shortfall caused by project underperformance.
