Voluntary emission reductions (VERs) focus on sustainability rather than just carbon reduction and allow renewables projects to produce truly game-changing results. So says Tom Morton of ClimateCare, a developer and marketer of this type of offset internationally. 'It's important to intervene early in a country's development to introduce sustainable, low-carbon practice rather than wait until unsustainable practices develop,' he said, suggesting that, for example, micro-renewable energy technology funded by VERs could avoid the need for a centralised grid fuelled by large-scale coal.
